Abstract: The study analyzes the relationship between the psychophysiology of EEG waves and the personality factor called extraversion in the Big Five model. We monitored the brain activity of the participants using EEG (scanning was done with Unicorn Hybrid Black) and collected information about their personality traits (DAS++ Questionnaire), especially the level of extraversion. The results of the study showed that there is a significant correlation between certain characteristics of the EEG waves and the level of extraversion of the individual. This finding suggests that there is a link between brain function and personality traits, in this case extraversion. The study helps to understand how biological and psychological aspects of the individual interact to influence human personality and behavior. Personality determination contributes to the correct estimation of expectations and behavior, with significant effects on the personalization of products and services.
