In the Event-related Potential (ERP) session, electroencephalographic (EEG)data was recorded for 90 participants, 60% of whom were females. The participants responded to30 universal emotional pictures, randomly chosen from the International Affective Picture System(IAPS), which were classified as invoking high, moderate, and low intensity of emotional arousal.Results:
From the analysis of variance of two-way mixed design, the interaction betweensex and emotional intensity was observed in the occipital regions (O2), indexed by the amplitudeof P300 and N200 components.
