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 (Ntotal = 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.
