报告简介：

Eye gaze is very important for attentional orienting in social life. By adopting the event-related potential (ERPs) technique, we explored whether attentional orienting of eye gaze is modulated by emotional congruency between facial expressions and the targets. Analyses of the late positive potential (LPP) elicited by targets revealed a significant modulation effect of emotional congruency on the gaze cuing effect. Threatening targets elicited larger LPPs when validly cued by gaze in faces with negative expressions (fearful, angry). Similarly, neutral targets showed larger LPPs when validly cued by faces with neutral expressions. Such effects were not present after happy face cues. Source localization in the LPP time window revealed that for threatening targets, the activity of right medial frontal gyrus could be related to a larger gaze orienting effect for the fearful rather than the angry condition. Our findings provide electrophysiological evidence for the modulation of emotional congruency on gaze cuing effect.
