Extraverts Reap Greater Social Rewards From Passion Because They Express Passion More Frequently and More Diversely.

Passion is stereotypically expressed through animated facial expressions, energetic body movements, varied tone, and pitch-and met with interpersonal benefits. However, these capture only a subset of passion expressions that are more common for extraverts. Indeed, in an initial dyadic study of supervisors and their subordinates (N = 330), extraverts expressed their passion more strongly through these stereotypical expressions of passion, and observers perceived extraverts as more passionate than introverts. Across three studies (N_total = 1,373), we subsequently developed a more comprehensive passion expressions and behaviors scale (PEBS). Using this measure in a daily diary study (N = 206, k = 1,862), we found that extraverts not only expressed their passion in more stereotypical ways, but through a broader variety of expressions in general. Extraverts are perceived as more passionate because they have a broader behavioral repertoire, express their passion more frequently and diversely, and thereby attain greater interpersonal rewards.
