[Reflection of the capacity of children for solving mental tasks in EEG activity]. / Otrazhenie v EEG-aktivnosti rabotosposobnosti detei pri reshenii myslitel'nykh zadach.

The present study is devoted to estimation of intellectual work ability of 47 subjects aged from 11 to 13, by the character of their integrative brain activity organization as reflected in EEG and recorded during solution of mental tasks. A comprehensive material (1374 EEGs) reveals four basic forms of brain activity organization, reflecting four fundamental mechanisms of information processing in the course of thinking, the adequate interaction of which ensures successful solution of tasks. The suggested method of evaluation of intellectual ability for work by means of EEG provides for its correct identification in 94-83% (learning sample) and in 92-72% (control test) with high degree of significance (probability 0.999).
