Аннотация: Emotional Intelligence (EI) is a psychological concept which has been investigated over a relatively long time period. However, research into the related neurobiological mechanisms underlying EI is relatively novel. While the effects of individual differences in EI on several ERP components in response to facial expressions have been demonstrated (Raz et al., 2013), the question of how people with high and low EI recognize emotional and neutral faces has not yet been investigated. In this study, we have analyzed the effects of individual differences in EI on the late positive potential (LPP) of the brain, in response to emotional and neutral facial expressions. Thirty-five healthy individuals (26F, 9M) participated in our study. To measure EI, we administered the Emotional Intelligence Test (EIT, Sergienko et al., 2019). For the facial emotion recognition task we used 40 grayscale photographs (20 male and 20 female faces) from the WSEFEP Database and Chicago Face Database (Ma, Correll, Wittenbrink, 2015). Stimuli were presented randomly for 600 ms. The participants were asked to recognize facial expressions by choosing one of the suggested options (1 — neutral expression, 2 — happiness, or 3 — anger). EEG brain responses were registered with 64 active electrodes, placed according to the international 10-10 system, recorded with the Brain Products ActiChamp amplifier (BrainProducts, Munich, Germany). In line with the previous findings, our results showed significant differences between high and low EI groups in the mean amplitude area of LPP (340-500 ms) in response to angry (p=0.051) and neutral faces (p=0.046) at parietal areas. Contrary to the previous studies, the same analysis for frontal and occipital areas revealed no significant differences (p>0.05). Overall, the current study reveals the effect of EI levels on the brain parietal areas’ activity during facial emotion recognition. Our results suggest that individuals with higher EI allocate greater cognitive resources to processing emotional and non-emotional faces at late processing stages.
