The P2 component reveals the early perception of varied hues of colors differs between art majors and non-art major

The study investigating whether there are different perception cognitive processes in varied color hues between art and non-art groups remains unknow. The study aims to investigate how different color hues affect cognitive perception. Participants, divided into art (n=22) and non-art (n=22) groups, completed tasks using cool, warm, and neutral hues while their EEG and behavioral data were recorded. The behavioral findings indicated that participants from both groups consistently rated the emotional valence of warmer colors higher than that of cool or neutral hues. The event-related potentials results revealed that warm colors elicited larger P3 amplitude than the other two hues for both groups. Additionally, there was a significant interaction effect between group and hue for the P2 components. The P2 amplitudes for the three hues varied significantly for the non-art group, but not for the art group. Decoding analysis revealed that both the art and non-art groups showed significant difference between the three stimuli using permutesion test in the P2 component time-window. The t-test also showed that the decoding accuracies for the art and non-art groups were significant difference during the time window of P2 component. The pattern of findings in this study indicated that warm and cool colors induced stronger attention than neutral hues, with warm colors being the most positive in terms of emotional appraisal, and the early color perception of the art group may differ from the non-art group.
