【 摘 要 】

The investigation of emotional face processing has largely used faces devoid of context, and does not account for within-perceiver differences in empathy. The importance of context in face perception has become apparent in recent years. This study examined the interaction of the contextual factors of facial expression, knowledge of a person's character, and within-perceiver empathy levels on face processing event-related potentials (ERPs). Forty-two adult participants learned background information about six individuals' character. Three types of character were described, in which the character was depicted as deliberately causing harm to others, accidently causing harm to others, or undertaking neutral actions. Subsequently, EEG was recorded while participants viewed the characters' faces displaying neutral or emotional expressions. Participants' empathy was assessed using the Empathy Quotient survey. Results showed a significant interaction of character type and empathy on the early posterior negativity (EPN) ERP component. These results suggested that for those with either low or high empathy, more attention was paid to the face stimuli, with more distinction between the different characters. In contrast, those in the middle range of empathy tended to produce smaller EPN with less distinction between character types. Findings highlight the importance of trait empathy in accounting for how faces in context are perceived.
