The present study examined effects of thinking on social judgment. The following two hypotheses were tested: (1) The subjects who thought about a stimulus person would judge statements concerning the person with smaller latitude of acceptance, with larger latitude of rejection, and with smaller latitude of noncommitment than the subjects who were distracted from thinking. (2) The subjects who thought about the stimulus person would spend less time to form the judgments above than the subjects who were distracted from thinking. Twenty-four male undergraduates watched a video-tape which showed a stimulus person. Half of the subjects were instructed to think about the stimulus person for two minutes. The other half of the subjects were distracted from thinking for two minutes. Nine statements which described the behavioral intentions toward the stimulus person were displayed on a screen of a micro-computer. The subjects first judged whether the statements were acceptable, and then judged whether the statements were rejectable. Their judgments and the response time which they spent to judge were measured. The results supported both of the hypotheses.
