Abstract
The formation of perception and voluntary attention functions is the basis for the development of the child's cognitive activity. The implementation features of the voluntary attention processes on the models of simple and complex visual search in groups of subjects with an age range from 8 to 18 years old were studied. Reaction time, errors (goal's omissions, false alarms), time for cognitive processes, correlations and features of attention efficiency in subjects with various academic performances were analyzed. The search time for a single element in a random location of an empty grid decreases with age. Errors such as "false alarm" prevail in younger age groups. The effectiveness of visual search can be one of the criteria for academic performance. Young men and women with low academic performance make significantly more mistakes such as "false alarm" in visual search tasks. The front-parietal attention system is the main one for the implementation of sensorimotor reactions. The maturation of this system can be the basis for increasing the attention effectiveness with age.

Summary
Использование компьютерных устройств для поиска, хранения и предъявления информации привело к очевидным изменениям в жизни общества и отдельного человека, причем дети начинают интенсивно использовать такие средства с раннего возраста [9]. 1. Время поиска одного элемента в случайном месте пустой решетки прогнозируемо было самым длительным в группе детей 8–9 лет по сравнению с группами 10–12 лет, 13–15 лет и 18–19 лет (t = 3,7, p = 0,0004; t = 3,3, p = 0,001; t = 6,7, p = 0,004). Среднее время сенсомоторных реакций при осуществлении простого поиска не различалось в группах детей 10–12 лет и 13–15 лет.
