| Abstract: | In this study, we investigated the emotional effect of dynamic presentation of facial expressions. Dynamic and static facial
expressions of negative and positive emotions were presented using computer-morphing (Experiment 1) and videos of natural
changes (Experiment 2), as well as other dynamic and static mosaic images. Participants rated the valence and arousal of their
emotional response to the stimuli. The participants consistently reported higher arousal responses to dynamic than to static
presentation of facial expressions and mosaic images for both valences. Dynamic presentation had no effect on the valence
ratings. These results suggest that dynamic presentation of emotional facial expressions enhances the overall emotional experience
without a corresponding qualitative change in the experience, although this effect is not specific to facial images.
