FACS

In the present study, we analyzed the facial expressions of surprise in two different situations (alone in the room and with another person in the same room; the alone condition and the same room condition) by using AU system of FACS. As a result, the effect of presence of another person is different between the emotion-instruction method and the photograph-instruction method. But the effect of presence of another person in the facial expression of surprise is not stronger than other facial expression. Consequently we consider that the display rule is not seen along the positive-negative dimension only, but it is different depending on the kind of emotion. The facial expression's consistency between the alone condition and the same room condition is significantly different. However because the instruction method in this study does not let the encoders show the spontaneous facial expression, in the future we must investigate the effect of presence of another person treating the spontaneous facial expression. The facial expression's constancy concerning JACFEE is significantly different. This result indicates the effect of the photograph-instruction method as the instruction method pf surprise, and the discrepancy between the facial expression of surprise in JACFEE and that in emotion-instruction method.
