| Abstract(in English) | It has been proved that a smile is perceived more accurately and promptly comparing with other facial expressions. Three types of facial expressions eg. a felt smile, a false smile and a neutral facial expression were used by controlling a fixation point and duration of a stimulus presentation, to investigate : (1)the effect of the partial and spatial frequency information on perception of a smile and (2)the factors which enhance the perceptual speed for a smile. The results show that the error rate of facial expressions is small when the fixation point was set between the eyes of a stimulus, and that a subject could not discriminate a felt smile from a false smile without the information of a mouth shape. Those result indicate the superiority of perceptual speed for a smile to that of other facial exrpressions is based on the information of a mouth. |
