An Event-Related Potential Study of Emotional Processing to Personal Experience of Everyday Things

摘要

This study used a self-attitude judgment paradigm to investigate the electrophysiological correlates of emotional processing (positive, neutral and negative) to everyday things/ events (objective word). Participants were asked to judge whether they like (positive item) or dislike (negative item) objective word which represented everyday things/events according to their personal experience. Results showed that similar with emotional word; both positive and negative items of objective word elicited a larger late positive component (LPC) than neutral item between 400ms and 700ms, which might reflect recollecting personal experience with special feelings and emotions. This might be the first one to use ERP technique to study the neural basis of emotional processing to personal experience of everyday things/events, and this result supported the idea that emotion feeling might not only be governed by the properties of the stimuli, but also in large part shaped by individual values.
