According to the properties of the percept image, the information processing rate in the sensory
system and, as a result of this, its dissemination in the analyzer depends on a person’s individual qualities. The
goal of the research is to study the features of visual information distribution depending on the pole of cognitive
style: field-dependence/ field-independence (FD/ FID). Materials and methods of the research. The study
involved 60 healthy right-handed (according to self-report) males and females. Visually evoked potentials for
chess pattern (VEPCP) were registered, and the test “Gottschaldt figure” was used to study individual perception
features by the cognitive style FD/ FID. Results and discussion. The study of both linear and curvilinear
correlation relations in the system of VEPCP components allows us to characterize the intra-system connections
of the visual analyzer, and reflect individual characteristics as well. The analysis of the connections revealed
have showed that males are characterized by a continuous adjustment of visual attention directed at a geometric
object, which is confirmed by a high number of curvilinear connections; in females, the primary zone of the
visual cortex is mainly involved in the processing of visual information, and a high number of linear relations
between the latencies of VEPCP components. Field-independent males and females have initially a greater
number of intra-system connections of component latencies, which is characterized by a large amount of
subcortical and cortical structures being involved in the processing of visual information received directly during
attention concentration.
