Dyad rapport and the accuracy of its judgment across situations: A lens model analysis

Ecology of rapport and its perception within 2 contexts (i.e., adversarial and cooperative) were examined from a Brunswikian perspective. A lens model analysis determined (a) which observable cues were indicative of rapport, (b) whether observer judgments covaried with such cues, and (c) whether observers could assess accurately the rapport between opposite-sex interactants. Whereas the manifestation of rapport was context specific, judgment policies used by observers were not. Rapport judgments were driven by target expressivity regardless of social context. Results suggest an ''expressivity halo'' in behavioral stream judgments that is analogous to the physical attractiveness halo found in judgments made from still photos. Finally, social perception accuracy was higher in the cooperative context where rapport was more strongly associated with target expressivity.
