Abstract

The accurate recognition of emotion is important for interpersonal interaction and when navigating our social world. However, not all facial displays reflect the emotional experience currently being felt by the expresser. Indeed, faces express both genuine and posed displays of emotion. In this article, we summarize the importance of motion for the recognition of face identity before critically outlining the role of dynamic information in determining facial expressions and distinguishing between genuine and posed expressions of emotion. We propose that both dynamic information and face familiarity may modulate our ability to determine whether an expression is genuine or not. Finally, we consider the shared role for dynamic information across different face recognition tasks and the wider impact of face familiarity on determining genuine from posed expressions during real-world interactions.

Highlights

Face perception is a crucial part of social cognition, and on a daily basis, we encounter many faces
Much behavioral and neural work suggests that dynamic information can be useful in face expression recognition, when recognition is difficult
We propose that for familiar faces, there may be additional cues that help us determine whether an expression is genuine or not, for example, a particular lop-sided smile associated with the genuine smile of a friend

Summary

INTRODUCTION

Face perception is a crucial part of social cognition, and on a daily basis, we encounter many faces. It is important to consider the way in which expression sets are created They are created by telling or showing the “actors” how to display prototypical expressions [based on facial action coding scheme (FACS) coding; Ekman and Friesen, 1978]. Our overall aim is to explore the role of dynamic information in determining genuine from posed expressions. We consider the role of dynamic information when recognizing facial expressions. We critically consider the difference between genuine and posed emotional expressions, in terms of the static- and dynamic-based cues available. We consider the possible mediating effect of dynamic information and face familiarity when discriminating between genuine and posed expressions
