How affect shapes status: distinct emotional experiences and expressions facilitate social hierarchy navigation.

All human societies are organized hierarchically, and individuals who occupy positions of high social rank typically acquire fitness advantages over lower ranking group members. Here, we argue that certain emotions function, at least in part, to help individuals successfully navigate these hierarchies. We review evidence suggesting that nine distinct emotions - pride, shame, anger, fear, sadness, disgust, contempt, envy, and admiration - influence social rank outcomes in important ways; most notably subjective experiences of these emotions motivate adaptive status-relevant behavior, and nonverbal expressions associated with these emotions send adaptive messages to others which facilitate expressers' attainment and maintenance of social rank. In sum, the reviewed emotions are thought to have intrapersonal and interpersonal consequences relevant to the navigation of social hierarchies.
