This article tests hypotheses derived from status-generalization theory and communication-accommodation theory that behaviors resulting from status inequalities emerge when attractiveness differentiates dyads. Relying on unobtrusive acoustic analysis of 24 women's voices, we test the extent to which(1) women adjust nonverbal behavior to one another; (2) more attractive women exert more influence than less attractive partners; and (3) the effects of attractiveness on influence are stronger if a greater relative difference exists between partners. Findings suggest that if two interacting women are similarly attractive, then they compete dynamically for status, which informs recent developments in the expectation-states research program. KEY WORDS: physical attractiveness; status accommodation; status characteristics.Individual physical attractiveness is a variable attribute, resource, and status characteristic that has evaluative meaning if people who are more attractive are more highly rewarded. Past research has found that perceptions of, or expectations for, certain desirable traits or outcomes vary with the attractiveness of people being judged. In particular, looks influence inferences about character traits, abilities, sociability, and intellectual competence (e.g., Jackson et al., 1995). Moreover, being attractive elicits social, psychological, and economic consequences (see Sullivan, 2001 for review). Such findings probably reflect the stereotyped expectation that "what is beautiful is good" (Dion, 1972:285).
