The purpose of this chapter is to review the various theories of facial emotion lateralization and to provide an examination of the research conducted to date that addresses these theories, drawing upon evidence primarilyfrom behavioraland lesion studies. The chapter focuses on human research, but studies from primates are also considered. The lateralization of facial emotion is discussed in terms of demographic factors (e.g., age and gender), valence (i.e., positive or negative emotions), and elicitation procedure (i.e., posed vs. spontaneous). The chapter evaluates theories pertaining to hemispheric specialization (e.g., the valence hypothesis) and location-specific differences (e.g., upper vs. lower face) during facial emotional expression. Finally, the chapter concludes with suggestions about directions for future research.
