The purpose of this study was to confirm the negativity bias in changes in impressions. The effects of the subjects' attributions regarding the stimulus person on the formation of impressions were also examined. The subjects (95 undergraduates) were requested to read either a positive or negative discription of the stimulus person in order to form impressions of him. Each description consisted of two different types, one with cues expected to induce situational attributions and one without. After 10-minute distraction, the subjects were requested to read the other description and to rate their impressions again. One week later, the subjects were asked to rate their recent impressions of the stimulus person without being manipulated or provided with any additional information on the stimulus person. The results revealed that negative impressions were more resistant to changes and more persistent even one week later. The introduction of the situational cues failed to manipulate the subjects' attributions. Furthermore, it is suggested that model behaviors have a dominant influence on both the evaluation and activity dimensions of impressions.
