Abstract: Perceptual processing of emotional facial expressions occurs very quickly, even without awareness.To determine whether the fast processing of facial expressions is categorical, we studied temporal characteristics of categorical perception (CP) of facial expressions.We investigated the effect of shortening stimulus duration on participant performance with respect to identifying and discriminating morphed facial expressions.The results of two experiments showed that CP was attenuated or even disappeared when facial stimuli were presented for as briefly as 50-75 milliseconds.These findings indicate that CP is irrelevant to the fast perceptual processing of facial expressions.
