In our study it was shown, that active formation of attitude, which determined the following decision making process leads to ERP cognitive component late waves amplitude increase, especially - P3 wave. Important differences in evoked activity parameters between persons, who realized the covert logic of stimulation material and persons, who didn't realize this logic, are observed not only during poststimulus period, but also during prestimulus period, approximately 1,5 sec before stimulus presentation. The features of differen cortex regions EEG oscillation relations also testifyes to the presence of specific brain mechanisms, which were related to stimulation logic estimation, and which were observed during this time interval. It was shown in our study, that persons, who realized the covert stimulation logic, in compare with persons, who didn't realized it, have specific source of brain evoked activity in temporal cortex brain area, which is related to speech nervous centers (Brodman area 24).
