The present study investigated the dynamic aspects of facial movements in spontaneously elicited and posed facial expressions of emotion. We recorded participants' facial movements when they were shown a set of emotional eliciting films, and when they posed typical facial expressions. Those facial movements were recorded by a high-speed camera of 250 frames per second. We measured facial movements frame by frame in terms of displacements of facial feature points. Such microtemporal analysis showed that, although it was very subtle, there exits the characteristic onset asynchrony of each part's movement. Furthermore, it was found the commonality of each part's movement in temporal change although the speed and the amount of each movement varied along with expressional conditions and emotions.
