Neurophysiological Correlates of the Aesthetic Judgment Formation in Conditions of Joint Paintings Perception

The article is devoted to the study of neurophysiologicalcorrelates of art work (paintings) perception under the conditionsof conscious (implicit) formation of the evaluative opinion aboutthem. Participants (24 subjects, 18–60 years old, median 22.5 years,6 male, 18 female) visited the exhibition of modern artists andin pairs viewed the paintings selected by each other and sharedtheir opinions on the selected paintings. For each participant,the spectral powers of the EEG were compared in the states of “viewingyour own choice” and “viewing the painting selected by the partnerin the pair”. According to the EEG spectral analysis, a group ofsubjects can be divided into 2 subgroups, between which there were nodifferences when viewing a self-selected painting, but there weredifferent reactions when viewing paintings that were chosen by apartner. In the first subgroup (14 people), lower power values (theta(4–8 Hz), alpha-1 (8–10 Hz) and alpha-2 EEG bands) were obtainedduring perception of the own chosen painting while in the secondsubgroup (9 people), lower power values (in delta (1.6–4 Hz), theta(4–8 Hz), beta-1 (13.7–18 Hz) and beta-2 (13–30 Hz) EEG bands) wereobserved when viewing the paintings chosen by the partner. We canassume a difference in the strategies for evaluating a painting chosenby another person.
