For the recognition of six basic expressions (happiness, surprise, fear, sadness, anger and disgust) using, as the stimulus, Japanese facial expression images composed on the basis of the FACS (Facial Action Coding System), the time spent by the observer was measured for scanning each facial area (forehead, brow, eye, nose, mouth and cheek) of the stimulus. In Bamba and Uemura (2007), the visual fixation point seen by the observer preceding the presentation of each stimulus was located in the area corresponding to the middle of the two eyes of the stimulus. In the present study, we examined the observer's fixation under four different conditions for the prefixation point, viz. corresponding to the upper, lower, left and right positions of the subsequent stimulus. The fixation time was measured by means of an Eye-tracker. Twenty undergraduate and graduate students of a women's university participated as the observers. The results showed that the longest fixation time required was in the eye area in all the six facial expressions, regardless of the location of the pre-fixation point.
