AbstractThe paper presents the results of tests on visual cognitive evoked potentials in 215 schoolchildren with high level of anxiety aged 13–18 years. Boys have increased latency and decreased amplitude of P2 and Р300 components of visual cognitive evoked potentials, which reflect the activation of specialized information processing systems, final stimulus identification and decision-making. No such reactions were observed in girls with high level of anxiety aged 13–17 years. In addition, 13-year-old boys and 14–15-year-old girls had reduced amplitude of N2 peak. N2 amplitude reflects the processes of focused attention, and its reduction may indicate attention deficit in girls and boys with high levels of anxiety. Thus, high level of anxiety leads to most pronounced changes caused by brain bioelectrical activity in boys and is characterized by changes in both early and late components of visual cognitive evoked potentials.Keywordsschoolchildren, high anxiety, visual cognitive evoked potentials, brain bioelectrical activity.References
