Abstract
Objective: Set functional peculiarities of the organization of cognitive activity of the high-school students caused by the type of interhemispheric asymmetry of the brains.
Methods: Comparative analysis of central nervous system was conducted among 250 students (9–11 grades) using variational chronoreflexometry, computer test “Landolt ring” and intelligence test.
Results: Teenagers having left hemisphere type of functional brain asymmetry prevailed (56%). The number of schoolchildren with the domination of right hemisphere didn’t exceed 40.4%. Equi-hemispheric students made 3.6%. Higher level of functional mobility of the nervous system was detected among children having left hemisphere type of functional brain asymmetry. It defined the optimal level of cognitive performance.
Conclusions: Low level of the development of cognitive functions’ dynamics among students having right hemisphere domination determines the necessity of training games usage for the purposes of the development and improvement of the cognitive abilities defining the level of academic performance of the students.
