Interpersonal dynamics may play a crucial role in the perpetuation of stereotypes. In an experimental study, participants interacted with a confederate who provided either stereotypeconsistent or stereotype-inconsistent descriptions about the elderly. Based on the assumption that mimicry represents a social glue that fosters interpersonal liking and affiliation, we assessed the extent to which participants mimicked the nonverbal behaviors of the confederate as a function of the stereotypicality of the descriptions. Results showed that nonconscious mimicry was more likely when the speaker relied on stereotypes rather than on stereotype-inconsistent information. In Study 2 the effect was replicated in relation to national stereotypes. This finding indicates that stereotypers are faced with subtle nonverbal cues from the audience that can retroactively reinforce their behaviors and thus make stereotype dismissal so difficult to be achieved.

Indeed, intraindividual cognitive processes tend to selectively enhance the encoding and memory for stereotype-consistent information (see Fiske, 1998), and interpersonal communication processes tend to favor stereotype-consistent information (Lyons & Kashima, 2003;Ruscher, 1998; see Kashima, Klein, & Clark, 2007, for a review). For instance, when a story is transmitted through communication chains, it rapidly undergoes very specific transformation such that stereotype-consistent information is retained whereas stereotypeinconsistent information tends to be omitted (Lyons & Kashima, 2001. In this way, recipients of communication are finally left with biased descriptions of persons and events. In addition, stereotype-consistent and -inconsistent information is transmitted at different levels of abstraction, and the use of abstract language in the case of stereotypical information further conveys the idea that stereotypes do generalize across situations and group members (Wigboldus, Semin, &
