EEG CORRELATIONS OF IMPLICIT PERCEPTION OF SENTENCES EMOTIONAL COLORING WITH STRATEGIES OF REAPPRAISALAND SUPPRESSION OF EMOTIONS
The aim was to study the relations of individual characteristics of emotional regulation with changes of bioelectrical activity of the brain during the implicit perception of emotional coloring of verbal information. The study involved 43 volunteers (26 women) aged from 18 to 34 years, the individual characteristics of emotion regulation strategies were measured by using the Emotional Regulation Questionnaire (J. Gross), and the total electrical activity of the brain (EEG) during presentation negative, positive and neutral sentences was analyzed. In order to distract attention from the emotional content of sentences, subjects were given a task to search for a syntax mistake. The search for a syntax mistake had to be performed as quickly as possible, while the presence of the emotional content in the sentence was not emphasized. We revealed that Cognitive reappraisal positively correlated with theta rhythm in interval from 100 ms to 300 ms during the presentation of negative sentences which did not contain a syntax mistake. Also, Suppression of emotions positively correlated with the beta rhythm in the range from 100 ms to 1300 ms during the presentation of positive sentences with a syntax mistake.
