Comparisons of amplitudes of the indexes for neuronal habituation between groups. The S2_Index_habituation (top panel) and S3_Index_habituation (bottom panel) of N1 (left panel), P2 (middle panel), and LNC (right panel) amplitudes were compared between High-AQ (solid bars) and Low-AQ (dotted bars) groups during the Pain Judgment Task (blue bars), Gender Judgment Task (grey bars), and Passive Listening Task (red bars). The High-AQ group exhibited altered neuronal habituation of empathic responses to others’ vocal pain during the Passive Listening Task. Data in bar charts are expressed as Mean ± SEM. *: p < 0.05, **: p < 0.01, ***: p < 0.001.
