How emotional expressions motivate action

Social adaptation requires humans to respond to others’ nonverbal emotional cues by selecting and executing adaptive motor responses. In this chapter, we provide a general overview of how visual perception of others’ emotional expressions, particularly threatening faces and bodies, promotes rapid processing and elaboration of multiple opportunities for action, at different levels of complexity. Notably, we will highlight how subcortical and cortical neural pathways interact to flexibly orchestrate our social behavior in response to threatening expressions, ranging from simple stimulus-driven reactions to more elaborated goal-directed actions. We will review recent findings from research on humans and other animals and discuss clinical implications, as well as future challenges and perspectives.
