Overall, EEG patterns exhibited qualitative consistency with PAD emotional evaluations, supporting the valence hypothesis. The findings elucidate the mechanisms by which decorative oil painting styles and interior environments jointly influence emotional experiences. This study provides scientific evidence for interior design optimization, art curation, and environmental psychology research, offering practical references for enhancing visual experience and emotional congruence in interior spaces.
