Hypothesis-testing processes in social interaction.

This research is concerned with the processes by which individuals use social interaction to actively test hypotheses about other people. In four separate empirical investigations, female participants were provided with hypotheses about the personal attributes of other individuals (quot;targetsquot;). Participants then prepared to test these hypotheses (i.e., that their targets were extraverts or that their targets were introverts) by choosing a series of questions to ask their targets in a forthcoming interview. In each investigation, participants planned to test these hypotheses by preferentially searching for behavioral evidence that would confirm these hypotheses. Moreover, these search procedures channeled social interaction between participants and targets in ways that caused the targets to provide actual behavioral confirmation for the participants hypotheses. A theoretical analysis of the psychological processes believed to underlie and generate both the preferential search for hypothesis-confirming behavioral evidence and the interpersonal consequences of hypothesis-testing activities is presented. In the course of social relationships, individuals often attempt to make judgments about the personal attributes of other people. At times, this quest for knowledge may involve the testing of hypotheses about other people. When we form our early impressions of new acquaintances, we may wish to test hypotheses based upon our expectations about their personal dispositions (Is this new acquaintance as friendly as a mutual friend has This research and the preparation of this manuscript
