Are those who are more invested in developing and maintaining interpersonal relationships able to provide more accurate judgments of others' personality characteristics? Previous research has produced mixed findings. In the present study, a conceptual framework was presented and methods were used that overcome many of the problems encountered in past research on judgmental accuracy. On four occasions, 102 judges watched a 12-min videotaped dyadic interaction and described the personality of a designated target person. Judges' personality characteristics were described by self, parents, and friends. Results revealed that psychological communion was positively associated with judges' accuracy in rating targets' personality characteristics. In addition, whereas women were more communal and provided more accurate judgments than men, the relationship between communion and accuracy held after controlling for the effect of gender. Finally, preliminary findings suggested that interpersonally oriented individuals may sometimes draw on information about themselves and about stereotypical others to facilitate accurate judgments of others.
