The effects of attitudinal similarity and task-relevant affiliative status, together with three situational factors (presence or absence of a monetary reward, choice of information source or work partner, and choice made before or after Ss completed preliminary work on the task), on the choice of comparison others were examined. The most significant determinant of the comparison other chosen was attitude similarity (p < .01). There was also a significant interaction between attitude similarity, task-relevant affifliative status, and time of choice (p < .05). The nature of the interaction suggested that general impressions such as conveyed by general attitudinal information may be more important in the selection of referent others than comparability on situation-specific factors.
