The course of improvement on recognition of facial expressions of emotion as a reflection of their inter-relationship

摘要

Present report includes two studies in which exposure duration of facial expressions of emotion was manipulated In Exp.1, participants observed facial photographs presented with varying durations of exposure, ranging from 4 ms to 64ms at a 4ms step and answered what was appeared. A dual scaling analysis extracted two major components that interpreted as valence and arousal. Results revealed that a positive emotion and a highly aroused emotion such as surprise and fear were easily recognized under a relatively brief exposure of the stimuli. Exp. 2 replicated and extended the findings of Exp.1, although different task demands might lead to somewhat discrepancy.
