The chapter summarizes an author’s research in the field of child neuropsychology, devoted to the dynamics of non-verbal visual gnosis in 365 children aged 4–6 with typical development. Data from a study of perceptual operations in difficult conditions (a sample to identify incomplete images), the deficits in which they are considered as a predictor of dyslexia, are analyzed. Against the backdrop of a predominantly analytical (left brain) strategy in the processing of visual incentives, a progressive improvement in the holistic (right brain) strategy was also noted, especially in children aged 6. The positive dynamics of identifying visual stimuli in difficult conditions by integrating distinct signs in the 4–6-year period is explained both by the activation of the holistic processing strategy and by the increasing participation of the prefrontal cortex in the functioning of the complex forms of non-verbal visual gnosis.
