Abstract:
The purpose of this research was to examine dynamic aspects of facial movements involving “posed” (intended) facial expressions versus “elicited” (unintended) emotional facial expressions. Participants were shown Gross & Levenson’s set of standardized emotional film stimuli1, and their facial expressions were recorded by a high-speed video camera (250 frames/second), which allowed us to analyze facial movements very closely in image sequences. These movements cannot be seen with a regular video camera (30 frames/second). In addition, participants were asked to produce facial expressions of happiness, surprise, and disgust based on the Facial Action Coding System (FACS). The findings suggested that the patterns of facial movements in posed facial expressions and elicited emotional facial expressions are not significantly different, but that there are differences in the intensity of the facial expressiveness.
