A social relations variance partitioning of dyadic behavior.

The authors investigate the relative importance of actor and interaction partner as determinants of dyadic behavior. Using the social relations model (D. A. Kenny, 1994a; D. A. Kenny & L. La Voie, 1984), the authors estimate the variance attributable to each determinant plus the reciprocity of behavioral responses from 7 studies. The authors find evidence for moderate behavioral consistency in a person's behavior across interaction partners, little or no evidence that people consistently engender the same behavioral response from others, and preliminary evidence of unique responding to particular partners. They also consider several methodological issues concerning behavioral measurement as well as the implications of the results for the study of accuracy.
