Abstract
: We provide an overview of the current state-of-the-art regarding research on facial behavior from what we hope is a well-balanced historical perspective. Based on a critical discussion of the main theoretical views of nonverbal facial activity (i.e., affect program theory, appraisal theory, dimensional theory, behavioral ecology), we focus on some key issues regarding the cohesion of emotion and expression, including the issue of “genuine smiles.” We argue that some of the challenges faced by the field are a consequence of these theoretical positions, their assumptions, and we discuss how they have generated and shaped research. A clear distinction of encoding and decoding processes may prove beneficial to identify specific problems – for example the use of posed expressions in facial expression research, or the impact of the psychological situation on the perceiver. We argue that knowledge of the functions of facial activity may be central to understanding what facial activity is truly about; this includes a serious consideration of social context at all stages of encoding and decoding. The chapter concludes with a brief overview of recent technical advances and challenges highlighted by the new field of “affective computing” concerned with facial activity.
