The study was aimed to investigate the connection between psychological personality traits and behavioral and EEG reactions to emotionally colored sentences with obscene words among 11 adult Yakuts and 42 Russians. During the experiment, every participant was asked to solve the error recognition task in 220 Russian written sentences containing emotionally colored words. 20 of these sentences contained an abnormal assessment of the aggressor. The results showed that grammatical errors were recognized slower and worse if a sentence described aggression in an abnormal form. In such sentences, the Yakuts were more successful in recognizing errors than Russians. For sentences with abnormal aggression, people with higher level of intelligence showed worse performance in recognition of grammatical error in comparison with lower intelligent participants. In women of both nationalities, EEG theta synchronization was significantly reduced when recognizing obscene vocabulary, as compared to men. Theta synchronization when considering sentences containing emotionally colored vocabulary in Russian men was greatly higher than in Yakuts.
