\r\n\tThis book will describe the self-assembly of materials and supramolecular chemistry design principles for a broad spectrum of materials, including bio-inspired amphiphiles, metal oxides, metal nanoparticles, and organic-inorganic hybrid materials. It will provide fundamental concepts of self-assembly design approaches and supramolecular chemistry principles for research ideas in nanotechnology applications. The book will focus on three main themes, which include: the self-assembly and supramolecular chemistry of amphiplies by coordination programming, the supramolecular structures and devices of inorganic materials, and the assembly-disassembly of organic-inorganic hybrid materials. The contributing chapters will be written by leading scientists in their field, with the hope that this book will provide a foundation on supramolecular chemistry principles to students and active researchers who are interested in nanoscience and nanoengineering fields.

1. Public significance statement
Positive illusions, the tendency to view self, others, or other phenomena more positively than objective criteria suggest, is common to the human experience. This study explores the impact of positive illusions in the context of personal relationships. How one views ones’ partner (positive illusion or objectively) has important consequences on the success of that relationship.
2. The influence of self- and partner-enhancement, perceptual congruence and personal identity on relational satisfaction among married couples, dating couples and same-sex roommate dyads
When Taylor and Brown [1] presented research evidence that positive illusions—the belief that I rate higher in any given domain than objective evidence would suggest—have a beneficial influence on a person’s life satisfaction, well-being, and relational success; heated debate followed. Early on Colvin and Block [2], Colvin et al. [3] were the primary antagonists questioning both Taylor and Brown’s methodology and conclusions and went on to cite research that demonstrated the benefits of perceptual accuracy (e.g., [4, 5]).
A good deal of research has provided support for the Taylor and Brown perspective (e.g., [6, 7, 8, 9, 10]), but other researchers have demonstrated the opposite. For instance, Robins and Beer [11] found that positive illusions may produce short term benefit but often result in long-term negative consequences. Other studies also demonstrated challenges with positive illusions and the benefits of greater accuracy of perception (e.g., [12, 13, 14, 15, 16]).
Since there appears to be evidence on both sides of the issue, this study attempts to unravel the dynamics of when illusion or accuracy produces better results. Baumeister [7] has already demonstrated that as the magnitude of illusion increases, the benefit diminishes. But we extend beyond Baumeister’s efforts to explore a number of factors that may influence when illusion (or enhancement) is beneficial or harmful.
To accomplish this, three different types of ratings are employed: subject ratings, partner ratings and test results.
Subject ratings. The subjects rate themselves on six traits, four temperaments and 15 personal characteristics on 7-point scales.
Partner ratings. The partners rate the subjects on the same six traits, four temperaments and 15 personal characteristics on the same scale.
Tests. The subjects take personality or temperament tests (details provided later) that measure the six traits and four temperaments.
Then the influence of enhancement or congruence on relational satisfaction is explored. Specifically, the study addresses congruence or enhancement in three different settings:
Self-enhancement: do Subjects rate themselves higher than test results;
Partner-test enhancement: do the Partners rate the Subject higher than test results; and
Partner-Subject enhancement: do Partners rate the Subjects higher than the Subjects rate themselves.
We pause a moment to operationalize several terms or phrases. The term Subject (always capitalized) refers to the primary participant who self-rates on a number of qualities and then takes tests for comparison with the self-ratings. The Partner (always capitalized) refers to the other member of the dyad who assesses how he or she thinks the Subject rates on the same personal qualities. Enhancement refers to positive differences among test results, Subject ratings, and the Partner ratings. Deviation refers to the differences (absolute values) among the same three. The term relational satisfaction is the score on the Dyadic Adjustment Scale (DAS, [17]) and represents the primary dependent variable. To avoid redundancy we form two abbreviations: Subject RS and Partner RS.
A second issue explored is what George and George [18] call “essence qualities”. It parallels Erikson’s view of personal identity [19, 20], but differs in that essence qualities identify specific areas in which an individual is heavily defined. In the questionnaire, 15 different personal qualities are Presented and Subjects rate to what extent they are defined by each of the 15 on 7-point scales. The Partners then rate the Subjects on the same 15 qualities.
The inclusion of essence qualities allows two additional types of exploration:
First, since Subjects rate themselves and Partners rate the Subjects on essence qualities, contrasts between Subject- and Partner-ratings can be employed to measure the impact of these differences on relational satisfaction. This broadens the overall investigation to 25 different personal characteristics to test enhancement or congruence between Subjects and Partners Twenty-five is far more extensive than most studies in this area.
Second, the influence of the strength of essence qualities on relational satisfaction can also be measured. Linville [21] research allows some interesting parallels. She found that self-complexity has a significant positive impact on relational success and overall life satisfaction. It is anticipated that strength of essence qualities would have a similar effect.
3. Literature review
Positive illusions: do they exist and how are they measured. There is little controversy about the existence of positive illusions. The tendency to view one’s self and important people in one’s environment more positively than reality is common to the human experience (e.g., [1, 22, 23, 24, 25, 26]).
Several methods have been used to measure positive illusions: A common one is to measure one’s self on a particular quality then measure hypothetical others on the same quality (e.g., [1, 26, 27]). In relationships, illusion may be measured by comparing an individual’s perception with the perception of their partner (e.g., [9]). Lewinsohn et al. [28] contrasted the opinion of experts with the opinion of the subjects. In the objective world, there is often opportunity to compare with actual standards (e.g., [29]). Example: I think I’m really smart. A test reveals an IQ of 87. My perception is illusion. In the medical world, one’s perception of likelihood or speed of recovery can also be contrasted with actual results (e.g., [26]). Example: A cancer patient thinks he will live another six months. He actually lives another four months. His opinion was illusion. In the present study we employ the method of research found in the objective domain: Self-perception is contrasted with results of an assessment instrument.
In addition to illusion about self, there is also a significant literature that deals with illusion about someone else. In the context of romantic relationships, the illusion applies to one’s partner. The phrase “love is blind” dates back 650 years [30]. The meaning then and now is identical, and refers to the tendency to view one’s partner with an unrealistically positive bias. Gagné and Lydon [31] and Solomon and Vazire [32] both address this phenomenon and argue that it is possible for one to have both positive bias and realistic appraisals of their romantic partner. In the present study, equal attention is devoted to both self-bias and partner-bias.
Positive illusions are associated with greater relational satisfaction. The logic of beneficial positive illusions was suggested by Bandura [33] who stated that if everyone viewed themselves entirely accurately they would only attempt tasks they could easily accomplish. Those who view themselves more positively often put in “the extra effort needed to surpass their ordinary performances” (p. 1176).
In addition to Taylor and Brown’s work [1, 26], Murray, Holmes and Griffin’s [10] longitudinal research with a sample of dating couples revealed that good relationships were a combination of accepting certain negative qualities and idealizing (positive illusions) the strengths of their Partners. A year later, Murray and Holmes [9] included married couples into their study with similar results. Neff and Karney [34] and George et al. [35] found that people with higher relational satisfaction tend to see their Partners in a more positive light, to idealize their positive qualities and to view their own relationship as superior to others. Babincak [6] with a sample of 154 undergraduates found that those with an inflated view of themselves experienced greater personal and relational satisfaction. Morry, Reich, and Kito [8] found that with a sample of 92 cross-sex friendships, 90 dating couples and 94 married couples partner enhancement resulted in greater feelings of being understood, validated and overall relationship quality. This is only a sampling of an extensive literature on this topic (e.g., [36, 37]).
Partner enhancement is associated with poorer relational satisfaction. The logic of a negative impact of a Partner having positive illusions about a Subject, is suggested by the marriage proposal. Many times, agreement to marry is concomitant with the rosy glow that renders inflated perception (positive illusions) of personal characteristics of their partner and ends down the line with divorce.
Robins and Beer [11] revealed that in personal relationships, positive illusions about one’s partner may produce immediate happiness but result in long term diminishment of well-being, self-esteem and poorer relational success. Tucker and Anders [16] found that anxiously attached married men experienced poorer marital satisfaction due to their inability to accurately perceive their Partner’s feelings. Cooper, Chassin, and Zeiss [13] found that congruence between the husband’s self-concept and the wife’s perception of the husband’s self-concept was associated with greater relational satisfaction. An older study [15] found that greater relational satisfaction was associated with congruence between the husband’s expectations and the wife’s perception of those expectations.
Personal qualities. The influence of personal qualities on relational satisfaction has been explored in many studies. Research has found that four of the six qualities used in this study are related to greater relational satisfaction: emotional stability (e.g., [38, 39]); agreeableness (e.g., [38]); social skills (e.g., [40, 41]); and spirituality (e.g., [42, 43, 44, 45]; Shaffer, 2008). Hostility and depressiveness are predictors of lower relational satisfaction (e.g., [46, 47]).
4. Summary
The present research is exploratory. Since there is such a diversity of research outcomes in this field, hypotheses are difficult to form. What this study does contribute is a more objective assessment of enhancement or congruence by including comparisons with test results. Then, greater validity is achieved because of 25 personal qualities are used in these comparisons (see [48] for a discussion of these issues). Finally, the ability to include enhancement, congruence, diminishment, or deviation as predictors (of relational satisfaction) allows greater comprehensiveness.
The dependent variable is relational satisfaction as measured by the Dyadic Adjustment Scale (DAS). As mentioned earlier, subject relationship satisfaction is designated “Subject RS”; partner relationship satisfaction is designated “Partner RS”. This study explores whether enhancement (Subject-test, Partner-test, Partner-Subject), congruence (Subject-test, Partner-test, Partner-Subject), deviation—the absolute value of differences between the same three contrasts, and strength of essence qualities has a significant impact on relational satisfaction. These comparisons are measured for the entire sample (N = 406) and for the three subsets of the sample: Married couples (N = 203), dating or engaged couples (N = 100) and same-sex roommates (N = 103).
5. Method
5.1 Participants
A total of 812 subjects participated. They were assessed as dyads and were identified as the Subject and the Partner. Thus, there were 406 Subject-Partner pairs: 203 were married couples, 100 were dating or engaged couples, and 103 were same-sex roommates. The married couples were defined as legally married or cohabiting for at least one year. Dating and engaged couples were self-identified. Roommates were defined as living in the same dorm room or house and were restricted to same-sex roommates in a non-romantic relationship. All romantically involved couples were heterosexual.
Gender breakdown included 432 women (53%) and 380 men (47%). The ethnic composition of the group was 56% Caucasian, 11% Black, 11% Asian, 15% Hispanic and 7% other. The mean age of the married couples was 43.1 years (range 21–85); mean age of the dating/engaged couples was 25.1 years (range 18–59) and the mean age of roommates was 22.8 (range 18–61). Other demographics included religious affiliation, amount of education, and duration of the relationship. Married couples averaged: 3.4 years of college and 16.7 years married (range: 2–47 years). Dating couples: 2.6 years of college, 2.0 years dating (range: 1 month – 5 years). Same-sex roommates: 2.6 years of college, 1.6 years as roommates (range: 1 month – 3.4 years).
6. Materials
Materials included separate questionnaires for the Subjects and the Partners. The Subject questionnaire was four pages (2-sided) and the Partner questionnaire was two pages (2-sided). The questionnaires were identical for married and dating/engaged couples. They were also identical for roommates except for the relationship-satisfaction questions, which were adapted to measure satisfaction in the context of a non-romantic relationship.
The questionnaires. The Subject questionnaire began with 2/3 page of instructions, including the sponsoring organization, brief description of the study, assurance of confidentiality, informed consent, debriefing and further instructions about how to complete the hardcopy or the online versions. This was followed by six demographic items, 18 items that measured Essence Qualities, 10 items that allowed Subjects to make a self-rating on each of 10 personal qualities, and 60 items assessed social skills, agreeableness, depression, hostility, emotional stability and spirituality. Next followed a 24-item test adapted from the DISC that measured temperament types, and the final page measured relationship satisfaction with the Dyadic Adjustment Scale (DAS, [17]).
The Partner questionnaire included the same instructions and the demographic items. However, for the 18 Essence Qualities, the six personality measures, and the four DISC temperament measure, rather than rating themselves, they rated the Subject. The Partner questionnaire concluded with the Dyadic Adjustment Scale (DAS) to measure their own relational satisfaction.
6.1 Procedure
Students from an undergraduate research-methods class at a university in Central Alberta, collected data for partial class credit. They were provided with a script to use when approaching potential participants. The method of approach included face-to-face, telephone, email, and a variety of social media resources—always using the pre-prepared script.
Two different methods of assessment were used: Hard-copy and online versions of the questionnaire: 180 dyads completed the hard copy; 226 completed the online version. After hard-copy forms were completed, Subjects sealed the survey in a coded envelope and returned it to one of several collection boxes on campus. For online forms, when Subjects completed all questions, results were automatically forwarded to the central database.
All data were entered and analyzed. Irregular or incomplete forms were discarded prior to data entry. The most common type of discarded form was when one individual from the dyad responded but their Partner did not. More specifically, there were 812 valid forms. An additional 50 forms were discarded due to being incomplete or irregular. A depressing 292 forms were valid but were unpaired with a Partner and thus were unusable in the present study.
6.2 Variables
Overview. The study is complex and includes several different classes of variables and several types of analyses or manipulations of those variables. Because of this, the following road map will provide context.
Classes of variables include:
Demographics: Subjects and Partners each report their own demographics.
Six different personality traits: Three types of measures occur here: (a) a single self-rating by the Subject, (b) a single Subject-rating by the Partner, and (c) a test to measure each trait— completed by the Subject only.
Four different temperament types: Three types of measures occur here: (a) a single self-rating by the Subject, (b) a single Subject-rating by the Partner, and (c) a test to measure each temperament—completed by the Subject only.
The Essence Qualities: Two types of measures occur here: (a) a single self-rating for each of the 15 by the Subject, (b) a single Subject-rating for each of the 15 by the Partner.
Four broad classes of analysis include:
The direct influence of all variables on RS (Relational Satisfaction).
The influence of three types of enhancement (Subject-test, Partner-test, Subject-Partner) on RS.
The influence of three types of deviation (Subject-test, Partner-test, and Subject-Partner) on RS.
The Profile Similarity Correlation (described later) computes the similarity of ratings among test results, Subject ratings, and Partner ratings.
Demographics. Included are gender, ethnicity (Black, White, Asian, Hispanic, Other), age, religious affiliation (several prominent Protestant denominations, Catholic, agnostic, atheist, other) amount of education (scale ranging from less than high school to doctorate), and duration of the relationship.
The self-ratings. Subjects were asked to rate themselves on the six personal qualities: agreeableness, emotional stability, social skills, spirituality, depressiveness, and hostility and the four DISC temperaments: Dominant, Influencer, Supportive, Conscientious. Each of the self-ratings was scored on a 7-point scale. For trait measures, the upper and lower anchors varied based on the qualities being measured. The middle score was 4 (about as much as others) or an equivalent phrase. For temperament measures, the anchors were identical: 1 (not in the slightest) to 7 (yes, that’s me!).
Appreciate that a self-rating on a trait is attempting to measure a single quality. Temperament, by contrast, is multi-faceted and statements appear to be not only double-barreled, but multi-barreled. The unique value of temperament measures (in a counseling or seminar context) and the difficulty of measuring these constructs for use in research, is fully appreciated. Because of this, the temperament measures see only limited use in this study. Two examples follow:
[trait—social skills] I have excellent social skills in a wide array of situations. 1 (very poor social skills), 4 (about as good as others), 7 (excellent social skills).
[temperament—“S” Supportive] I am cooperative, kind, loyal, patient, and enjoy encouraging and supporting others 1 (not in the slightest), 4 (to some extent), 7 (yes, that’s me!)
Personality trait measures from assessment instruments. The choice of the six traits was based on the experience of the authors and their colleagues in a counseling context. All six personality variables have demonstrated their influence in the success and non-success of relationships. All variables produced a final measure ranging from 1 to 7 with 1 representing low levels of a particular quality and 7 associated with high levels.
Spirituality. Personal spirituality was assessed by 12 questions selected from the 18-item George-Mabb-Walsh Spirituality Scale [49]. All questions were measured on 7-point scales; anchors varied depending on the nature of the question. Three of the items were reverse coded. The final spirituality measure was the mean of the 12 items with 1 representing low levels of spirituality and 7 high levels.
Agreeableness, Emotional stability. Two predictors were selected from the Big Five Personality Inventory [50]: Agreeableness (9 items) and Neuroticism/emotional stability (8 items) were rated on 7-point scales that ranged from 1 (Strongly disagree), to 4 (Neutral) and 7 (strongly agree). The final measure for both variables was the mean of the relevant items.
Social Skills. Social skills was measured by 11 questions selected from the Carlsmith Social Skills Scale [40]. Items were rated on 7-point scales. Anchors varied based on the nature of the questions. Three of the items were reverse coded. The final measure was the mean of the 11 ratings.
Depression. Depression was assessed by 11 statements that measured depression from the Anxiety and Stress Scale [47]. Scales, scoring and the final measure were identical to those for Social skills. Thus, 1 represents low levels of depression and 7 high levels.
Hostility. Hostility was measured with 10 items selected from the State Hostility Scale [46]. Subjects indicated to what extent they agreed or disagreed with each of ten statements. Each statement was scored on a 7-point scale with the same anchors as those used in the Big 5. The final Hostility measure was the mean of the 10 items with 1 representing low levels of hostility and 7 indicating high levels.
DISC Temperament Scale measures. Four temperament qualities were assessed by an adaptation of an on-line version of the DISC Temperament Scale. Each of the four temperaments is associated with one of the four letters of D-I-S-C (Dominant, Influencer, Supportive, Conscientious). For instance, the description of the S (supportive) temperament is “I am cooperative, kind, loyal, patient, and enjoy encouraging and supporting others.”
The DISC assessment instrument included 24 lines of four randomly distributed words. In each line one of the words reflected the D (dominant) perspective; one of the words was associated with I (influencer); one with S (supportive) and the fourth word related to C (conscientious). Participants selected one word in each of the 24 sets. The raw score for D, I, S, and C was the sum of words that were circled. For this data set, D-scores ranged from 0 to 20; I-scores from 0 to 16; S-scores from 0 to 17; and C-scores from 0 to 17. To create metrics similar to other variables, raw scores were converted to 7-point scales based on a normal distribution of values utilizing the IBM SPSS® “Rv.Lnormal” procedure.
Essence qualities. Essence Qualities were assessed by Subjects rating to what extent 15 different attributes, widely found to be common defining qualities [18], were central to their identity. The items included: understanding, social, perceptive, generous, cherish family and family events, love of learning, deeply spiritual, ever growing, creative, disciplined, neat and orderly, musical, logical, and enthusiastic pursuit of fitness. The 15th item asked their profession and three additional lines were provided to include other options. These additional lines were heavily used as 67% of participants included at least one additional quality; 39% identified three additional qualities. All 18 items were rated on 7-point scales. The lower and middle anchors varied based on the quality described. The high anchor was 7 (central to my identity) for all 18. An example follows:
1. Disciplined. 1 (follow my urges), 4 (when necessary), 7 (central to my identity).
To reduce bias, the Partners also rated the Subjects on the same 15 measures. The final measure of the strength of each of the 15 Essence Qualities was the mean of the Subject’s and the Partner’s rating. This “criss-cross” method of reducing bias is widely employed in couples’ research (see [51]). The overall measure was the mean of the 15 criss-crossed scores. A score near 1 represents many low ratings across the 15 contrasting qualities; a score near 7 indicates many high ratings across these diverse qualities. The variable being measured is: “To what extent am I heavily defined across a number of contrasting qualities.”
Relational satisfaction, the primary dependent variable. Relational satisfaction was assessed by the Dyadic Adjustment Scale (DAS, [17]) and was scored in the manner specified by the authors. For the roommates (in non-romantic relationships), some of the questions did not fit their setting, such as “quality of sexual relationships.” Because of this, three of the 32 questions were deleted and one was adapted to better reflect a roommate setting (instead of “likelihood of divorce or separation,” roommates’ version was “likelihood of finding another roommate”).
Both Subjects and Partners completed the Dyadic Adjustment Scale (DAS) so the study could assess how different variables influenced both the Subjects’ relational satisfaction (Subject RS) and the Partners’ relational satisfaction (Partner RS).
6.3 Difference scores
Enhancement measures. The measures of enhancement and congruence in the present study involved difference scores. These differences were calculated between (a) Subject self-ratings and test results (to measure self-enhancement), (b) Partner’s ratings of the Subject and test results (to measure Partner enhancement), and (c) Partner’s rating and the Subject’s rating (to measure whether Partners rated Subjects higher than Subjects rated themselves). Also included was (d) Essence qualities. Since there were only Subject and Partner ratings only Partner-Subject enhancement could be measured
Once differences were calculated, they were changed to z scores to create metrics similar to other variables. Correlations or regressions between the difference scores and relational satisfaction identified whether enhancement benefits, had no effect, or diminishes relational satisfaction.
Congruence measures. There were also four different congruence measures. The congruence measures are simply the absolute value of the four types of enhancement measures listed above. Congruence measures assessed to what extent participants deviated from congruence either with test scores or with the Subject self-ratings. A score near zero suggests high congruence whereas larger scores suggest deviation from congruence—whether enhancement or diminishment.
6.4 Profile similarity correlation
The Profile Similarity Correlation measure is increasingly used in couples’ research (e.g., [52, 53]) but shows promise as a tool to better understand the dynamics of relational satisfaction. The PSC is designed to measure similarity of profiles between two members of a dyad. In the present study, PSCs were computed across 10 variables, the six personality variables and the four temperaments.
Four PSC measures were computed in the present study: (a) the correlations between the Subject’s 10 self-ratings and the Subject’s test results; (b) the correlation between the Partner’s 10 Subject-ratings and the Subject’s test results; (c) the correlation between the Partner’s 10 Subject-ratings and the Subject’s self-ratings; and (d) the correlation between Subject’s ratings of 15 Essence Qualities and the Partner’s rating of the Subject’s 15 Essence Qualities.
An example illustrates the usefulness of PSC. Let us say the Subject rates himself 4 s and 5 s on the 10 of the Essence Qualities and 1 s and 2 s on the other five. A hypothetical Partner rates the Subject 5 s and 6 s on the same 10 Essence Qualities and 2 s and 3 s on the other five. This profile illustrates two separate outcomes: Enhancement of the Subject by the Partner (the Partner consistently rates the Subject higher than the Subject rates himself) and a strong correlation between the two sets of values (a high PSC) due to the similarity of profile (high and low ratings by the Subject are matched by high and low ratings by the Partner).
If correlations between PSC and relational satisfaction are computed, a high correlation suggests that similarity of ratings is associated with relational satisfaction.
7. Results
The primary purpose of the study is to determine the influence of enhancement, congruence or diminishment on relational satisfaction among couples. In addition, we explore some related findings such as the influence of personal qualities and strength of Essence Qualities on relational satisfaction. We begin by reporting the psychometric validity of our variables and comparing our results with Baumeister’s.
7.1 Psychometrics

A comparison of the 360 (44%) participants who completed the hard-copy questionnaires with the 452 (56%) who completed the online version found few systematic differences between the two sets. The authors judged that the two groups were sufficiently similar to combine into a single data set.
7.2 Influence of degree of enhancement on relationship satisfaction
First, present results partially confirmed the Baumeister findings that more extreme illusions are less beneficial. However, there was only one setting where enhancement increased relational satisfaction: The Partner’s RS was higher if the Partner rated the Subject higher than the Subject rated him or herself (r[404] = .21, p < .001). However when the squared term was added in a stepwise regression analysis, the benefit dropped off significantly as the enhancement becomes greater: β = −.19, R = .40, R2 = .16, R2 change = .024, F-change (1, 403) = 11.523, p = .001. See Figure 1 that illustrates a positive linear relationship and a negative curvilinear relationship.
Figure 1.
Diminishment of benefit as enhancement becomes greater.
7.3 Influence of enhancement on RS
A brief overview of the central issue now takes place. The degrees of freedom for all correlations is 404 unless otherwise specified. Self-enhancement diminished both the Subjects’ (r = −.21, p < .001) and the Partners’ (r = −.14, p = .005) RS. The Partner-test enhancement resulted in lower Subject RS (r = −.18, p < .001) and had no effect on Partner RS (r = .08, p = .10). The Partner-Subject enhancement showed no effect for Subjects (r = −.03, ns) and, the one instance of support for Taylor and Brown, enhanced RS for Partners (r = .21, p < .001).
A different pattern emerged when considering enhancement of Essence Qualities. Since no instrument measures Essence Qualities, the only enhancement possibility is a comparison of Subject ratings on each of the 15 with the Partner rating of the Subjects’ Essence Qualities. The results found that Partner-Subject EQ enhancement was associated with greater relational satisfaction for the Subject (r = .14, p = .005) and even more so for Partner (r = .34, p < .001). Greater detail may be found in Table 2. Thus, with the exception of Partner-Subject enhancement, there was a consistent pattern of enhancement being associated with lower relational satisfaction.

Deviate: Absolute value of the enhance score. Positive correlation: greater deviation associated with greater RS. Negative correlation: greater deviation associated with lower RS.
7.4 Influence of deviation on relational satisfaction
Recall that deviation from congruence is the absolute value of (a) subject minus test, (b) partner minus test, and (c) partner minus subject. A score of zero indicates no deviation whereas a larger score indicates greater deviation.
The Subject-test deviation was associated with poorer RS for the Subjects (r = −.15, p = .002) and the Partners (r = −.17, p = .001). The Partner-test deviation predicted lower RS for the Subjects (r = −.17, p = .001) and the Partners (r = −.16, p = .001). Partner-Subject deviation was associated with lower RS (marginal) for the Subjects (r = −.10, p = .056) and the Partners (r = −.12, p = .016). Finally Subject-Partner Essence-Quality deviation showed a similar trend: lower RS for the Subjects (r = −.13, p = .010) and the Partners (r = −.14, p = .007). While no results were particularly robust, there was a consistent pattern of deviation being associated with lower relational satisfaction. Table 2 contains additional detail on how Marrieds, Dating, and Roommates fared on the same comparisons.
7.5 Influence of profile similarity coefficient (PSC) on relational satisfaction
Profile Similarity Correlations (for the entire data set) included:
Subject-test PSC. A high PSC predicted greater Subject RS (r = .26, p < .001) and Partner RS (r = .22, p < .001). A similar pattern emerged for all subsets except for the dating couples.
Partner-test PSC. A high PSC predicted greater Subject RS (r = .27, p < .001) and Partner RS (r = .34, p < .001). A similar pattern of significance emerged for all subsets.
Partner-Subject PSC. A high PSC predicted greater Subject RS (r = .31, p < .001) and Partner RS (r = .33, p < .001). A similar pattern emerged for all subsets except for dating couples.
Subject-Partner PSC for Essence Qualities. A high PSC predicted greater Subject RS (r = .11, p = .032) and Partner RS (r = .11, p = .035). Although results in the context of Essence Qualities are barely significant, the pattern is consistent with other PSC measures.
Thus in all four setting similarity of correlations (high PSC) is associated with greater relational satisfaction for both subjects and partners. See Table 2 for detail.
7.6 Influence of strength of essence qualities on personal characteristics and RS
The influence of Essence-Quality strength on relational satisfaction was consistent with Erikson’s theory. Stronger Essence Qualities on the part of the primary Subject was associated with greater RS for both the Subjects (r = .30, p < .001) and even more so for the Partners (r = .37, p < .001). A similar pattern of results was observed for all subsets.
7.7 Influence of personal traits on relational satisfaction
Both Subjects’ and Partners’ relational satisfaction was enhanced if they were more emotionally stable, agreeable, socially skilled, and spiritual, and was diminished if they were more hostile or depressed. The r-values ranged from .22 to .43 for the Subjects; from .12 to .28 for the Partners (all significance values were p < .001). It is interesting to note that the pattern of relationships was the same for both Subjects and Partners but the effect for Subjects was more robust in every instance.
7.8 Insights from regression analysis
This data set is not primarily designed for regression analysis or structural equation modeling. The study addresses several specific factors associated with relational satisfaction and there is no intent for it to be comprehensive. The objective of the regressions in this setting is not so much to attain high R2 values but rather to test the relative importance of the predictor variables and also partial correlations after other variables are accounted for.
Two analyses were conducted: the first included a criterion variable of Subject RS, the second a criterion variable of Partner RS. Predictors for both analyses included six discrepancy variables (the last six variables in Table 1), four PSC variables (subject-test, partner-test, subject partner, subject-partner essence qualities), essence qualities (single combined variable), and the six tested personality variables. For all analyses, Stepwise Multiple regression was conducted with a p to enter of .07 and a p to drop of .10. Note: Additional regressions were conducted with subsets of these variables; contact the first author for additional information.
Analysis 1. The regression on Subject RS found four variables entering the equation: Depression, β = −.27; Partner-Subject PSC, β = .12; Essence Qualities, β = .11; and hostility β = −.11. This generated R, R2 and DF values of: .47, .23, 1, 401.
Analysis 2. The regression on Partner RS also found four variables entering the equation: Essence Qualities, β = .23; Partner enhance Subject, β = .21; hostility, β = −.17; and Partner-Subject PSC, β = .14. This generated R, R2 and DF values of: .50, .25, 1, 401.
Thus, three qualities significantly influenced both Subject and Partner relational satisfaction: Strength of essence qualities, congruence between subjects and partners on the ten self- and partner-ratings (Subject – Partner PSC), and the negative impact of hostility. Depression was the greatest single predictor (negative) of the subjects’ relational satisfaction. The partner viewing the subject higher than subject self-ratings was the second-ranked predictor of the partners’ relational satisfaction.
7.9 Other differences
Analysis of gender differences were remarkable more for the similarity between men and women than for any differences. When contrasting type of relationships, for both Subjects and Partners, dating couples had the greatest RS (Ms = 4.86, 4.85), marrieds were next (Ms = 4.71, 4.67), and roommates were lowest (Ms = 4.32, 4.37). All pairwise comparisons were significantly different (α = .05).
8. Discussion
As the discussion progresses, the reader is reminded of the overall perspective of this study. Taylor and Brown [1] research supported the benefits of positive illusions in many settings. Subsequent research has instances of support or non-support for the Taylor and Brown Theory. Present findings are discussed in the context of identifying the influence of enhancement or congruence on relational satisfaction in several contexts.
8.1 The influence of enhancement
Three types of enhancement are explored in this study: Subject-test, Partner-test, and Partner-Subject. In contrast with the Taylor and Brown theory in almost all instances enhancement (positive illusions) is detrimental to relational satisfaction; both for the Subjects and the Partners. The only instance of support for Taylor and Brown is when Partners rate Subjects higher than Subjects rate themselves, the Partner’s relational satisfaction is enhanced.
This pattern holds true for each of the subsets except for married couples. Their results are in the same direction but not significant for the Subject and show a non-significant positive trend for the Partner. The contrast of the married couples is perhaps in the nature of their relationship. In an on-going and committed relationship, researchers find that attention to (and even enhancement of) the positives and the ignoring of the negatives is one key to success in many marriages (see [9, 34, 35]).
8.2 The influence of deviation from accuracy of perception
For all three settings, a deviation from congruence from either the test results or the Subjects’ self-ratings results in diminished relational satisfaction for both Subjects and Partners. When the Subject self-ratings deviate from the test results, the outcome is lower RS for Subjects and Partners and for each subset. An identical pattern occurs for deviation of the Partners’ Subject-ratings with test results, also significant (for the entire sample). The results are less robust for the Partner deviating from Subject ratings. Both show negative impact but are barely significant. Although marrieds, dating and roommates show a similar pattern of results their outcomes are often do not achieve significance. The influence of PSC helps to create a more complete picture.
8.3 The influence of profile similarity correlation (PSC)
The Profile Similarity Correlation measures how similar (highly correlated) are the pattern of ratings between the couples on a given set of variables. Also, as suggested in the introduction, the PSC can also measure enhancement or diminishment.
The PSC produced some of the strongest results in the entire data set. For three of the PSC measures (Subject-test, Partner-test, and Partner-Subject), not only are benefits to the relational satisfaction of both Subjects and Partners for entire sample significant at the .001 level, most of the subsets achieve the same significance.
The message is clear. When the results of deviation from accuracy and the PSC are considered, one may say that relational satisfaction (whether for Subjects or Partners) is associated with reasonable accuracy of judgment and congruence with both the Subject self-ratings and test results. When the occasional benefit of enhancement occurs (only for the Partner rating the Subject higher than the Subject rates herself) one is motivated to ask the question: Is this the type of enhancement spoken of by Robins and Beer [11] that yields short-term benefit but long-term misfortune?
8.4 The influence of essence qualities
In the present study, those high in Essence Qualities scored a perfect record (all at ps < .001) of being more agreeable, emotionally stable, spiritual, better social skills, while being less hostile, and depressed.
The results were nearly as strong with the benefit on Subject’s and Partner’s RS. Of all possible correlations (between Essence Qualities and relational satisfaction), the effect was significant at the .001 level for the entire sample and all subset except dating couples.
These results, despite being robust, should not be that surprising. Erikson [19, 20] anchored a strong personal identity (Stage 5) as the prerequisite to successful intimate relationships (Stage 6). Linville [21] also found emotional and relational health associated with her concept of self-complexity. The utility of essence qualities as a unique concept (despite similarities to Erikson and Linville) is their usefulness in a counseling or seminar context. George and George [18] have documented that almost never do a couple share identical essence qualities. In counseling, then, the couple can learn to enjoy the strength of shared essences and explore how to deal with essences that differ.
8.5 Variations based on the subsets
When considering the three primary subsets (marrieds, dating couples, roommates) responses were reasonably consistent with the overall results, except for the dating couples. Of 26 comparisons between the three groups, the dating couples produced similar but weaker results 16 times, completely opposite results 3 times, and were reasonably congruent results on the other six. Essentially, we found less influence on Subject and Partner RS by the dating couples than for the entire sample or the other two groups. Researchers speculate that the “in love” factor may be instrumental. “In love” is not an issue with the roommates and is less of a factor with the marrieds with an average duration of the relationships of 17 years. Perhaps the tendency of in-love Partners to idealize each other, renders the effects of enhancement, congruence or similarity to be not so great an influence. This also underlines the contention [18] that the dynamics of successful friendship (roommates in this case) are quite similar to the dynamics of successful romantic relationships.
8.6 Limitations of the study and conclusions
More might be done with the temperament measures. In this study, temperament was used only in the PSC correlations. The challenge of their multidimensionality provides difficulty for any researcher, but the multidimensionality is intrinsic to the concept of temperament. Their power in a counseling or seminar setting demonstrates that continued effort to provide effective ways to measure and employ them in research is desirable.
A possible solution is, perhaps, suggested by the measure of Essence Qualities in the present study. Essence Qualities are defined as contrasting qualities that define an individual. Yet a measure was derived “the mean of the 15” that measures strength of identity across a wide range of diverse qualities. Perhaps this provides some insights into the measure of temperament. Temperament should be easier to measure and conceptualize (than essence qualities) because the set of qualities are often highly correlated with each other.
Perhaps the greatest limitation of the study is that the areas in which enhancement or congruence were assessed (the six personality variables) is limited. There are thousands of areas in couple relationships that might also be assessed. How well do results from six variables extrapolate to enhancement or congruence across the wide array of other personal characteristics? Future studies might begin to systematically explore different classes of variables to gain a more complete picture.
8.7 A final word
The present study reveals that asking whether positive illusions are beneficial is too simplistic. The study appears to illustrate that positive illusions by the Partner may sometimes have benefit. But, this finding is overwhelmed by the weight of evidence that 1. assessment that is congruent with Subject ratings or test results, 2. assessment that does not deviate too far from the test or partner ratings, and 3. a high correlation between the perspectives of the one doing the judging and one being judged is beneficial to relational satisfaction.

1. Introduction
Bats are truly remarkable creatures, and fossil records indicate that they first appeared in the Eocene, some 50–55 million years ago [1]. They belong to the Order Chiroptera. This Order name means “hand-wing” as the bats can hold food between their forearms. Despite this primate-like gesture, it took quite some time for people to understand that bats are mammals and not birds. In the third book of Moses in the Old Testament, bats were identified as birds, while the world-famous Swedish taxonomist, Carl von Linné (or Linnaeus), only reclassified bats as mammals and not birds as late as 1758 in the 10th Edition of his “Systema Naturae” [2]. Because of the resemblance in dentition and such external phenomena as the thoracic position of the mammae, etc., the great Linnaeus himself ended to place the bat along with man in the order Primates [3].
Contemporarily the bats were divided based upon morphology and behavior into two suborders, Microchiroptera (Microbats) and Megachiroptera (Flying Foxes and Old World Fruit Bats) [4]. New molecular biology findings indicate that there are two new Suborders, Yinpterochiroptera and Yangochiroptera, not coinciding with the earlier subordinate classification [5].
There are more than 1400 bat species worldwide, and they make up roughly 20% of the world’s extant mammals [6]. They are hugely beneficial to man and play a major role in the well-being of the world’s ecosystems. Not only do they prey upon insects that are harmful to agriculture, but they also prey upon mosquitoes and other virus-carrying insects and play a major role in pollinating and spreading the seeds of many of the fruits we enjoy. In some parts of the world, they are a valuable food source, and their body parts are used in traditional medicine, while their guano is collected and used as agricultural fertilizer [7]. Why is it then that while in some parts of the world this beneficial creature is seen as a symbol of good luck and good fortune, in many societies it is viewed with fear and loathing? Here, using documented narratives, surveys, popular literature, and cinema, we will explore the various myths, legends, and attitudes to bats from around the world.
2. Europe
In the Bible, the bat is seen to be “unclean” [8], while its nocturnal activities ally it to malevolent spirits that roam the land when darkness has fallen. It is no real surprise that in a Christian Europe throughout history, the bat has been associated with the Devil, evil spirits, and witches [9]. Bats also have wings. Tertullian, an early Christian author from Carthage (155–220), claimed that the Devil and his angels had wings [10], and around 1314, Dante wrote that the Devil’s wings had no feathers, “but was in form and texture like a bat’s” [11]. In 1332, a French noblewoman, Lady Jacaume of Bayonne [12], “was publicly burned to death as a witch because ‘crowds of bats’ were seen about her house and garden.”
William Shakespeare (1564–1616) also equated bats with witches, spells, and curses. In Macbeth (1605), there is the incantation of the three witches: “Eye of newt, and toe of frog, wool of bat, and tongue of dog,” while there is Caliban’s curse on Prospero in The Tempest (1610–1611): “All the charms of Sycorax, toads, beetles and bats, light on you.”
There is also, of course, the European connection with bats to vampirism. Vampires had been part of Slavic folklore in Eastern Europe since the seventeenth and eighteenth centuries, but it was not until the nineteenth century that popular fictional literature, predominantly through Bram Stoker’s “Dracula” in 1897, would forever tie bats and vampires together, with the protagonist, Count Dracula, being able to transform himself into a huge bat [13]. While the three species of true vampire bats (common vampire bat Desmodus rotundus, hairy-legged vampire bat Diphylla ecaudata, and white-winged vampire bat Diaemus youngi) are microbats, measuring just a few centimeters in length, it was the exaggerated reports from early explorers and adventurers that gave the public the image of these huge bloodsucking creatures. In 1796, John Stedman wrote of being bitten by a vampire in Guiana, describing it as “a bat of monstrous size, that sucks the blood from men and cattle when they are fast asleep, even sometimes till they die.” [14]. This association between giant bats and vampires continues to the present day through popular fiction and cinema (Figure 1).

As with that other iconic nocturnal creature, the owl, the bat has a myriad of very strange old wives’ tales and superstitions surrounding it [15]. Here are just a few:
If a bat flies into your house, look out for bedbugs.
A bat flying into a building means that is going to rain.
It’s unlucky to see a bat in the daytime.
Killing a bat shortens your life.
Bats in a church during a wedding ceremony is a bad omen.
Bats in the house mean a death in the house or is a sign that the occupants will soon be leaving.
Bats flying vertically upwards and then dropping back to earth means that the Witches Hour has come.
Bats are symbolic of bad luck, especially when they call while flying early in the evening.
If a bat flies into a house and then escapes, there will be a death in the family. Kill the bat before it escapes, and everyone will be safe.
If a bat flies into a kitchen and at once hangs on to the ceiling, it is a lucky omen, but if it circles the room twice before alighting, it is a bad omen.
One of the most enduring old wives’ tales from Europe is that bats will get tangled in women’s hair and would have to be removed with a pair of scissors. Between 1958 and 1961, Gathorne-Hardy, Fifth Earl of Cranbrook, a renowned conservationist and a founding member and former President of the Mammal Society, decided to put this old superstition to the test [16]. Using two willing female teenagers, one with “relatively short curly hair” and one with “longer wavy hair was done up behind in a bun,” Cranbrook took turns in placing four different species of bat on their heads. A noctule bat Nyctalus noctula, a long-eared bat Plecotus auritus, a Natters bat Myotis nattereri and a Daubenton’s bat Myotis daubentonii. In all four cases, the bats each walked about the volunteers’ hair without becoming entangled in any way and finally took flight without any difficulty. The experiment was repeated several times with the same results [16].
3. Africa
Bats have fascinated humans for millennia, and this cultural and spiritual relevance is reflected in the presence of bat symbols in Egyptian tombs from 2000 BC [7]. In Africa, “house bats” occur in distinct colors and sizes, but they are usually hard to identify. Although they live near humans and are common, it appears that some of the species have not been described and given scientific names [17]. To date, ethnobiological information regarding bats in Africa has mainly focused on utilitarian aspects of bats as food and medicine, whereas knowledge concerning symbolism and beliefs surrounding bats in that continent has not been assembled, apart from ancient Africa [18], Ghana [19, 20], Kenya [21], and Madagascar [22].
Among the Ibibio people of southern Nigeria, bats are associated with witchcraft, and for any bat to fly into a house and touch a person is a sure sign that this person is thereafter bewitched and will soon perish because his or her heart is eaten at night while he or she sleeps. Also, in Nilotic Sudan, witchcraft was usually performed at night, and therefore, owls and bats were associated with it. In the Anglo-Egyptian Sudan, spirits, devils, and witches had their general name “Bitaboh,” wood-goblins being specially called “Ronga.” All the bats were comprehended under the same name, especially the Yellow-winged Bat Lavia frons, formerly Megaderma frons, which flutters about from tree to tree in broad daylight [18].
In Cameroon, the superstition of the vampire is attached to bats. Among the Ndop people, bats, owls, and bush-cats are said to be witch shapes. Should a bat or an owl come near the house, or a bush-cat defecate in the compound, the owner must go at once to diviner to discover what remedies must be taken to ward off the evil. A witch shape is believed to be capable to suck out the life of a sleeping man or woman [18].
From Sierra Leone comes an account of the gruesome habits of the Hammer-headed Fruit Bat Hypsignathus monstrosus. It is the largest bat found in continental Africa and was believed to suck the blood of sleeping children until they die. It was called “Boman,” and it was able to turn into a stone or a snake at will. Interestingly, blood sucking has been attributed to bats both in Cameroon and Sierra Leone despite the countries being widely separated and when no such type of bat is found in Africa [19].
Although the bats roost in the sacred forest in Ghana, they are not regarded as sacred animals. Bat hunting is illegal, but hunters readily admitted to having hunted bats and even directed the research people to other hunters. Bat meat is widely consumed because it is considered more delicious than other types of meat. However, consumption was influenced by religious beliefs, food taboos, and some myths about bats. Muslims and Seventh Day Adventists did not consume bat meat. Men hunt and consume bats more often than women who have fears that consuming bat meat would give them strange or deformed children. Bats are not associated with any diseases, and it was felt to be safe to eat bat meat, but both studies were conducted before the 2013 Ebola outbreak (Figure 2) [19, 20].

In Kenya, a bat attitude questionnaire was presented to 394 people living around the Arabuko-Sokoke forest. Belief in myths seemed to prevail among those surveyed. Just over one-third of the respondents (36%) did not see any benefits of bats to humans. Nearly another third reported actively killing bats or destroying bat roosts, and most respondents associated bats with the destruction of farmers’ fruits, especially mangoes. Female respondents in this study showed more negative attitudes and a stronger belief in myths about bats than males. Only older and somewhat educated people reported more positive attitudes toward bats than others [21].
In Madagascar, the exploitation of bats for bush meat regularly takes place during periods of food shortage, especially fruit bats, which are heavily hunted. The study estimated that in the karstic Mahafaly Plateau some 50–100 caves are exploited for bats and that between 70,000 and 140,000 Microchiroptera bats may be collected annually in the region. This is bound to threaten the continued existence of local bat populations. Thus, more famine relief food aid is desperately needed to reduce the bush meat use during the food crises, which are nearly annual in the region [22].
In Malawi, negative bat superstitions caused recently quite disproportionate behavior when rural people in southern parts of the country killed nine people accusing them to be “vampire bats” [23]. The police arrested 200 vigilante youth suspected of involvement in gangs that attacked persons allegedly engaged in vampirism. Medics said there is no truth or clinical evidence that blood suckers or vampires exist in Malawi, and the United Nations mission withdrew its personnel from the riots-affected areas [24].
4. Southwest Asia
In southwest Asia, bat folklore has been documented between Iran, India, and Myanmar [25, 26, 27]. In southwest Asia, the bat is predominantly perceived as a strange, negative, and demonic animal that should be avoided. Usually, it is regarded as a bad omen even if seen in a dream. The bat is a devil who flies only in the night because it would die if flying in the daytime [25].
In India, a total of 3059 high school students from 36 schools were questioned on their bat perceptions. Most students (56%) reported seeing bats in their locality. Half of the students knew that bats are mammals, but 26% believed them to be birds, some thought of them being amphibians (12%) or reptiles (11%); 37% disliked the bats, and 27% liked them remaining seeing them as indifferent. A substantial proportion (53%) thought that bats have medicinal value, but 35% saw them only as harmful creatures. They were believed to destroy trees and damage fruits in gardens. Over half of the students (57%) did not know anybody in their neighborhood who would hunt bats. The felling of roosting trees was mentioned as bat death reason by 29% and hunting by 18%. Most students wanted to participate in bat conservation activities, including some students who disliked bats. The study concluded that conservation-related education should be included in the school curriculum to ensure that students would appreciate not only the importance of bats but of all wildlife [26].
Bats are also revered throughout India. In Madurai, worshippers of the Muni god regard Indian Flying Fox Pteropus medius, formerly Pteropus giganteus, as sacred and protect colonies for fear of heavy punishment. However, after offering prayers, dead bats found on the ground can be eaten. In Pudukkottai, roosting P. medius is seen as the guardian of the sacred groves, and in Bihar, that bat brings wealth. Orchard owners in Myanmar believe that allowing bats to roost and feed in the garden ensures prosperity and well-being. Flying fox’s emergence time is believed in Myanmar to indicate the weather: an early or no emergence foretells a coming storm. Bats are also used as allegories to denote romantic or parental love in the poetry of Tamil Sangam literature in India [27, 28, 29].
In Hunza, Pakistan, a witch appears in the shape of a bat, and it plays a role in magical practice in southwest Asia. In the Punjab, northern India, magicians use bat bones to prepare their concoctions, and with the bat blood, they write amulets for malevolent and antisocial magic. Between Iran and Rajasthan, north-western India, there is the widespread public belief that if a bat lives somewhere in the house or hangs on the roof, this would mean bad luck for the owner [25]. In Pakistan, one belief is that if a bat enters one’s ear, it can never be removed and contact with bat urine is thought to cause eczema. On the other hand, the body fat of Indian Flying Fox is used to make massage oil to cure rheumatic pains, while drinking water from a bat’s wing is said to sharpen one’s memory [30]. In Sri Lanka, it is believed that one may be reincarnated as a bat for denying another person drinking water [31].
Pre-Islamic magical belief in Hunza said that “if the lady would once offer the cooked meat of bat to her guests, hiding it behind her back while serving” her family would never be without meat for their whole life [25]. Interestingly, Islamic taboo,
considers bat as harām meaning that it is forbidden as food. The official Islamic view is exempting bats from being killed because it would carry bad luck to kill a bat [32]. One reason not to kill bats is that “female bats have breasts and are mothers like human females” [25].
Bats are also seen as useful in Iran, India, and Pakistan because people are collecting bat guano as a natural fertilizer.
5. Southeast Asia
Throughout Southeast Asia, bats are associated with luck and good fortune and used as spiritual totems [6, 27]. Since the fourteenth century, Chinese culture has regarded bats as lucky animals, and these blessing bat symbols have been prevalent in Chinese arts over the centuries [33]. In Indonesia, farmers in South Sulawesi believe that flying foxes roosting near their rice fields guarantee a good harvest [27]. Similarly, fishermen in the Philippines consider mangrove roosting flying foxes to be guardians of their fishing grounds and to increase fish and shellfish catch [27]. In Malaysian Borneo, people consider it taboo to disturb a fruit bat. If a man whose wife is nearing childbirth unthinkingly does so, some harm may befall the unborn baby [34].
In Malaysia, a face-to-face survey was conducted in Penang Island to assess knowledge and awareness level toward bat conservation efforts. The bat populations in Malaysia are decreasing in 26% of species and only 15% are still stable. Bats are shot for sport or to eradicate them from fruit plantations. Bats are also considered as wild exotic meat, which is widely consumed in urban areas. Besides hunting, the primary threats to bat species include habitat loss and degradation through logging. Most respondents were less likely to value the importance of bats in the ecosystem, so creating a conservation education to connect people with nature is not easy. The oldest age group (51–70 years old) of 150 respondents were mostly aware of the bat conservation efforts. The higher level of education was not always reflected in the positive attitudes toward environment and wildlife issues. Participation by local people is vital to achieving successful conservation programs [35].
Iban people in Sarawak, Borneo, believe that a bat flying into the house indicates a shaman bringing good vibes, conferring protection against any harm, while in Thailand, if a bat enters a house but immediately flies away, it is believed to change bad luck to good. Should the bat stay and eat the fruit in the house, bad luck will befall the owner [27].
In northern Thailand, harming bats incurs a curse because bats are sacred for Buddhists [36]. In Irian Jaya of Indonesia, former head-hunters considered flying foxes to be head-hunters too, as they took the “head” of the tree by consuming its fruit [37].
Despite positive associations toward bats, they are widely consumed as food and medicine throughout Asia, except in Brunei and Singapore. In Malaysia, ethnic Han Chinese, non-Muslim indigenous groups, and ethnic Malays hunt flying foxes and trade them to the Chinese [27]. In Indonesia, Iban people in Kalimantan also hunt fruit bats for consumption, and mainly Christian people in North Sulawesi regularly eat flying foxes (Black Flying Fox Pteropus alecto and Sulawesi Fruit Bat Acerodon celebensis) especially during the Christmas season [38, 39].
There exists a widespread belief in Southeast Asia that eating bat meat cures asthma [27]. In many parts of Indonesia, people specifically consume bats’ livers and hearts as medicine [39]. In Thailand, bat meat or blood is eaten for muscle pain, increasing virility and longevity [36]. In Malaysia, older generations prevented thievery by mixing flying fox blood with milky mangrove Excoecaria agallocha tree sap to cause violent intestinal inflammation [40].
In Vietnam, many mounted bat species are sold in souvenir shops, and in Laos, bats are traded in several markets (Figure 3) [41, 42]. There is a Japanese word for bat, komori, which is said to mean “mosquito slaughterer.” In Japanese mythology, very old bats can transform into nobusuma, spirit animals resembling flying squirrels that land on their victims’ faces at night to feed off blood [43]. Indigenous Ainu people in Japan worshipped the crafty and wise bat god Kappa kamui, who kept away demons and diseases [44].

6. Pacific region
A legend tells that in Fiji, a giant white vampire bat acts as a messenger, and one finds bats as gods in both Tikopian and Tongan myths. The Tongan king’s Samoan wife was rescued by flying foxes, and she honored her rescuers later by naming her son Tonumaipe’a (= “rescued by flying foxes”) [45]. People in Vanuatu consider Pacific Flying Fox Pteropus tonganus as their ancestor and claim to be able to communicate with them [46]. In Makira, Solomon Islands, local people value traditional currency for transactions, such as bride price, and use the canine teeth of flying foxes as a traditional currency [47]. Samoan people prize flying fox meat as a delicacy and as a gift to elders, but commercial hunting and export of the meat are culturally frowned. The general attitude is that the flying fox is part of the forest, and the vast majority support the protection of Pteropus samoensis and P. tonganus [45]. Samoans said that flying foxes were cheeky and courageous, making it a popular tattoo motif [48].
In New Zealand, Māori people associate bats, pekapeka, with the mythical nocturnal bird hokioi that foretells death [49]. In 2021, a bat won New Zealand’s Bird of the Year competition name of which in Māori language is Te Manu Rongonui o te Tau, and the word “Manu” means “flying creatures,” including bats. The decision to include the New Zealand long-tailed bat Chalinolobus tuberculatus also known as pekapeka-tou-roa (Māori) in the 2021 Bird of the Year competition did cause a bit of controversy, some people saying the country had gone “batty.” However, the long-tailed bat got more than 7000 votes, bringing a clear victory to this critically endangered animal, despite not being a bird [50].
7. Central and South America
The diversity of South American bats is impressive as there are more bats, and more bat species, than in any other part of the world [51, 52]. In pre-Columbian Central and South America, the bat played an important role in the religions and social structures of the various cultures, most notably with the Moche people of Peru and the Maya of Guatemala. In northern Argentina, a Toba story tells of the leader of the very first people—a hero bat or batman who was teaching people all they needed to know as human beings. Similarly, the Ge tribe in Brazil moved through the night following a bat that looked for light toward which to guide the people (Figure 4) [51, 52].

The bat was central to Maya religion and social structure. One clan of the Cakchiquel Maya, of the highlands of Guatemala, was named the Zotzil (=belonging to the bat), whose deity was a bat. The Tzotzil Maya lived, and continue to live to this day, on the plateau of Chiapas in southern Mexico. They called themselves Zotzil uinic (batmen), claiming that their ancestors discovered a stone bat, which they took as their god, and their chief town was named Zinacantlan (=place of the bats) by Nahuatl merchants from Mexico [53]. Generally, the Maya revered a Vampire Bat god, Camazotz, the death bat, which killed dying men on their way to the center of the earth [51, 52].
The north coast of Peru is one of the South American regions where bat iconography is particularly prominent [51]. The Moche people in Peru were aware of the connection between bats and plants. On Mochica pottery, a bat is depicted with the Sweetsop Annona squamosa, a common fruit also known as Sugar Apple or Pinha, the seeds of which are dispersed by bats [51, 52]. Some of their ceramic vessels have an anthropomorphic bat that is an agent of human sacrifice, with a knife in one hand and a human head in the other. Sometimes a Mochica bat carries a warclub and a small human captive. The enormous size of the bat and the small human head or body indicate supernatural status for the bat [51].
The widespread sacrificial association derives largely from the habits of the Common Vampire Bat that feeds exclusively on the blood of vertebrates (Figure 5).

In many places, blood sacrifice was believed to benefit agriculture, and therefore, bats had agricultural, as well as death, connections for Pre-Columbian peoples and in Oaxaca, Mexico, a bat deity was associated with maize [51]. Surprisingly little folklore exists specifically about Vampire bats, and Pre-Columbian erotic scenes do not involve bats although some folklore portrays female bats as alluring to men.
One Yupa man in northern Colombia started night after night to drink and flirt with a female bat when he was returning from an evening hunt. Finally, his wife realized what he was doing and set fire to the tree and killed her husband and the bats [54]. Sometimes bats are husbands as in a Mataco lore from Argentina. A woman noted that her husband had a round tail and dropped the vessel of water she was bringing to him. The bat husband then cut off her head and those of other Indians and put all heads in the tree hole where he was living [55]. Also, a Tacana woman in Bolivia was killing a bat while not realizing that it was her husband [34].
In some folklore, bats often have sexual connotations, which may relate to fertility and agriculture as bats are important seed dispersers and pollinators of many fruit trees. Bat guano provides one reason for the fertility associations [56].
In Caribbean South America and the Antilles, bat images are associated with death rites and burials in archeological context [57], and in Cuba, a Taino ball court was bat-shaped, the ballgame being a sacrificial ritual [58]. In Jamaica, the bat and the owl were very important symbols in Taino mythology and death. The bat represented the opias (= spirits of the dead people) to the Taino. Fruit-eating bats such as Jamaican fruit bat Artibeus jamaicensis loves feeding on guavas, which is also the favorite food of the Taino spirits of the dead. In Jamaican folklore, bats are also perceived as death images [59].
In northern Guiana, Bat Mountain is the home of” killer bats,” and there is also a killer bat in folklore from Venezuela. Decapitating bat demons appears in various myths in Amazonia and to the south in northern Argentina. These myths associate killer bats with fire as the bat burns its victims and is, in turn, thrown into the fire [60, 61, 62]. One bat, whose habits may have fostered these tales of decapitating bats, is the false vampire Vampyrum spectrum. It is the largest New World bat with a yard wingspan. It is a carnivore, eating birds and other vertebrates, occasionally taking even other species of bats. When capturing its prey, it grabs the neck, sometimes killing the prey with a single powerful bite [51, 52].
8. North America
The artificial bat became a shorthand for horror in 1931, jiggled on a fishing line behind a Hungarian-American actor Béla Ferenc Dezsö Blaskó, known professionally as Bela Lugosi in the genre-defining movie Dracula. Shockingly, US news media recently reported shortages of Halloween decorations—plastic bats among them, doubtless—due to the world supply crunch [63].
Monstrous beyond imagining, all-consuming, blacker than blackest night, the hideous Satan in the Night on Bald Mountain section of Walt Disney’s animated film Fantasia (1940) spreads gigantic bat wings as it turns fiery eyes toward the lost souls about to be engulfed in wrath and flames [64]. This North American bat-like depiction should come as no surprise; it is merely another manifestation of the fear, horror, and superstition with which bats have been regarded down through ages [64]. Large, often man-eating, bats are found in Hawaiian traditions, and there is even a legend of an eight-eyed bat in Hawaii. Interestingly, giant bat stories have persisted in these” flying-fox-less” societies, which evolved from western Polynesians cultures where flying foxes have been prevalent [45].
Warner Shedd (2000) felt strongly that the level of fear about rabid bats sometimes rises almost paranoid concern in the United States, citing the State of New York as an example [63]. By using a million dollars annually “to educate” the public about the dangers of bat-caused rabies in humans simply exacerbates the already unreasonable fears, which many people have of bats. In its entire history, the state of New York has recorded only one case of bat-transmitted rabies [64]. Between the years 1950 and 2007, only 56 cases of bat-borne rabies transmission to humans occurred in the United States and Canada, which translates to 3.9 cases per billion person-years [65].
The recent introduction of a fungal disease (WNS = White-nose Syndrome) from Eurasia to North America has killed millions of bats in North America in the past decade. Although the exact source of the fungal pathogen, Pseudogymnoascus destructans, and its mode of introduction into North America remain unknown, the introduction was most likely mediated by humans, either through direct or indirect transfer of infectious propagules [66]. People can further move the fungus on their clothing and caving gear and spread the disease into an area that does not currently.
Even worse have been the vandalism and wanton destruction of bats and their habitat in North America. A variety of methods have been used to harass and kill these harmless and beneficial creatures, and some people have even gone so far as to dynamite caves and abandoned mines where bats roost or hibernate [64]. Lately, education seems to have some effect, and more and more people have started to appreciate how useful and amazing bats truly are. It remains to be seen, however, if this could halt or even reverse the decline of the North American bats [64].
9. Fear of bats
An irrational fear of bats—Chiroptophobia—encompasses negative perceptions of bats as disease vectors, pests, or harmful creatures associated with devils and witchcraft, which represents an important barrier to bat conservation globally [27]. Especially Western cultural associations of bats with evil spirits, which have been recorded in Christian tradition as early as the fourteenth century [68] along with current media sensationalizing bats and the COVID-19 pandemic, are major hindrances toward bat conservation [69], although there is no reason why public health messages cannot be consistent with bat conservation.
In Western culture, bats are also associated with vampires causing hysteria and wrong nomenclature of non-sanguivorous bat species such as Large Flying Fox Pteropus vampyrus. Despite its scientific name, it feeds exclusively on fruits, nectar, and flowers and not blood (Figure 6) [70].
Figure 6.
Large flying fox Pteropus vampyrus suffers from its misleading scientific name as it is not blood-eating species but feeds only fruits and flowers. Photo credit: Masteraah. “Creative commons”—Wikimedia. https://creativecommons.org/licenses/by-sa/2.0/de/legalcode.
Since the fourteenth century, Chinese culture has associated bats with good luck and blessings [33].
Even cultures that value bats positively may have values conflicting with bat conservation. Fruit growers may view fruit bats as crop pests [71]. Han Chinese people attach positive esthetic values to bats but may still hunt bats at unsustainable levels [72]. In India, bats are revered in many areas, but still large bat-harvesting festivals take place. In Nagaland between 7000 and 25,000 cave-dwelling bats (Cave Nectar Bat Eonycteris spelaea, Great Roundleaf Bat Hipposideros armiger, and Leschenault’s Rousette Rousettus leschenaultii) have been annually harvested until recently [73]. So, using positive symbolism alone to promote bat conservation might be insufficient without accounting for day-to-day relationships of local communities with bats. Conversely, negative symbolism could promote conservation if it prevents unsustainable hunting and consumption [27].
It is imperative to obtain more current ethnobiological data to further our understanding of contemporary attitudes and relationships with bats—and to document other cultural traditions not covered in this review.
10. Conclusion
Cultural traditions and beliefs influence the future of the bats, which is threatened by human exploitation, both directly on bats and indirectly on the environment.
To summarize shortly the various findings: In the West, bats have been seen as animals of ill omen, alongside other nocturnal hunters such as owls and black cats. Around 62% of the Asia-Pacific people had only positive cultural values of bats, 8% had only neutral values, while 10% had only negative values [27]. The remaining cultures had combinations of positive, neutral, and negative values.
This suggests that the Asia-Pacific region and its cultures contain far more positive associations with bats than most European or American societies and, as such, offer promising examples and opportunities to promote human-bat coexistence. For example, a number of these countries are investing in the burgeoning industry of ecotourism by promoting organized visits to bat caves and “bat watching” [74, 75]. In 2005, the privately owned Montfort Bat Cave Sanctuary on Mindanao Island, south of the Philippines, opened for tourism. The five-chambered cave hosts the world’s largest known colony of the Geoffroy’s Rousette Fruit Bat, Rousettus amplexicaudatus, with an estimated 1.8–2 million individuals [76]. The tour includes a brief 20-minute conservation education lecture about bats, caves, and the history of the Montford Bat Cave Sanctuary. The cave prohibits hunting and guano harvesting, while income from this ecotourism chiefly flows into local economy and enhances the sustainability and protection of the cave site (Figures 7 and 8).

Our collection of global perceptions aims to promote a better biocultural richness for humans and bats as our long-term nocturnal companions. But it became obvious that the public attitude toward bats has still not been investigated extensively enough throughout the world, namely in contemporary Africa, America, Australia, and Europe.

Attention deficit is one of the main symptoms of Attention Deficits Hyperactive Disorder, ADHD. Further, impaired attention is often part of learning disorders in dyslexia and dyscalculia as well as in students with no medical diagnoses. In schools and higher education knowledge on attention and challenges caused by impaired attention, is typically scarce. Hence, this chapter aims to inform educational institutions by applying Mirsky’s model of attention, discuss challenges of impaired attention, and point to intervention effects. The positive effects of real-life interventions comprising target shooting practice are explained by immediate neurofeedback combined with individual adaption and caring. Moreover, as previously hypothesised, the sequential order of behaviour at the shooting range may benefit students with impaired attention. The term concentration is frequently used in Norwegian schools and counselling services. A definition of concentration in natural situations is suggested, and possible overlaps between concentration and attention are discussed. The chapter opens for empirical and theoretical questions and hopes for more research on target shooting practice as well as on other educational programmes applying neurofeedback in the school context to investigate attention.",signatures:"Audhild Løhre",authors:[{id:"418731",title:"Prof.",name:"Audhild",surname:"Løhre",fullName:"Audhild Løhre",slug:"audhild-lohre",email:"audhild.lohre@ntnu.no"}],book:{id:"10910",title:"Learning Disabilities",slug:"learning-disabilities-neurobiology-assessment-clinical-features-and-treatments",productType:{id:"1",title:"Edited Volume"}}}],collaborators:[{id:"190980",title:"Prof.",name:"Marwa",surname:"Mahmoud Saleh",slug:"marwa-mahmoud-saleh",fullName:"Marwa Mahmoud Saleh",position:null,profilePictureURL:"https://mts.intechopen.com/storage/users/190980/images/system/190980.jpg",biography:"Professor Marwa Mahmoud Saleh is a doctor of medicine and currently works in the unit of Phoniatrics, Department of Otolaryngology, Ain Shams University in Cairo, Egypt.

Biochemistry examines macromolecules - proteins, nucleic acids, carbohydrates, and lipids – and their building blocks, structures, functions, and interactions. Much of biochemistry is devoted to enzymes, proteins that catalyze chemical reactions, enzyme structures, mechanisms of action and their roles within cells. Biochemistry also studies small signaling molecules, coenzymes, inhibitors, vitamins, and hormones, which play roles in life processes. Biochemical experimentation, besides coopting classical chemistry methods, e.g., chromatography, adopted new techniques, e.g., X-ray diffraction, electron microscopy, NMR, radioisotopes, and developed sophisticated microbial genetic tools, e.g., auxotroph mutants and their revertants, fermentation, etc. More recently, biochemistry embraced the ‘big data’ omics systems. Initial biochemical studies have been exclusively analytic: dissecting, purifying, and examining individual components of a biological system; in the apt words of Efraim Racker (1913 –1991), “Don’t waste clean thinking on dirty enzymes.” Today, however, biochemistry is becoming more agglomerative and comprehensive, setting out to integrate and describe entirely particular biological systems. The ‘big data’ metabolomics can define the complement of small molecules, e.g., in a soil or biofilm sample; proteomics can distinguish all the comprising proteins, e.g., serum; metagenomics can identify all the genes in a complex environment, e.g., the bovine rumen.

The applications of this research cover many related fields, such as biotechnology and medicine, where, for example, Bioinformatics contributes to faster drug design, DNA analysis in forensics, and DNA sequence analysis in the field of personalized medicine. Personalized medicine is a type of medical care in which treatment is customized individually for each patient. Personalized medicine enables more effective therapy, reduces the costs of therapy and clinical trials, and also minimizes the risk of side effects. Nevertheless, advances in personalized medicine would not have been possible without bioinformatics, which can analyze the human genome and other vast amounts of biomedical data, especially in genetics. The rapid growth of information technology enabled the development of new tools to decode human genomes, large-scale studies of genetic variations and medical informatics. The considerable development of technology, including the computing power of computers, is also conducive to the development of bioinformatics, including personalized medicine. In an era of rapidly growing data volumes and ever lower costs of generating, storing and computing data, personalized medicine holds great promises. Modern computational methods used as bioinformatics tools can integrate multi-scale, multi-modal and longitudinal patient data to create even more effective and safer therapy and disease prevention methods. Main aspects of the topic are: Applying bioinformatics in drug discovery and development; Bioinformatics in clinical diagnostics (genetic variants that act as markers for a condition or a disease); Blockchain and Artificial Intelligence/Machine Learning in personalized medicine; Customize disease-prevention strategies in personalized medicine; Big data analysis in personalized medicine; Translating stratification algorithms into clinical practice of personalized medicine.",coverUrl:"https://cdn.intechopen.com/series_topics/covers/7.jpg",hasOnlineFirst:!0,hasPublishedBooks:!0,annualVolume:11403,editor:{id:"351533",title:"Dr.",name:"Slawomir",middleName:null,surname:"Wilczynski",slug:"slawomir-wilczynski",fullName:"Slawomir Wilczynski",profilePictureURL:"https://s3.us-east-1.amazonaws.com/intech-files/0033Y000035U1loQAC/Profile_Picture_1630074514792",biography:"Professor Sławomir Wilczyński, Head of the Chair of Department of Basic Biomedical Sciences, Faculty of Pharmaceutical Sciences, Medical University of Silesia in Katowice, Poland.
