碩士 === 國立政治大學 === 心理學研究所 === 96 === The purpose of the present study was to utilize the directed forgetting task to investigate the memory bias in socially anxious individuals. Performance on a directed forgetting task was assessed in socially anxious (n=24) and nonanxious (n=20) individuals. Participants were presented with three types of words (negative social, neutral, positive social) and were cued to either remember or forget each word as it was presented. There were no between-groups differences on a free recall task for words in both remember and forget conditions. Follow-up analyses demonstrated that all subjects recalled more positive social words than either neutral words or negative social words in the remember condition, revealing the positive memory bias. However, only nonanxious individuals showed such positive memory bias in the forget condition, while high-social-anxiety individuals did not. Moreover, in the social anxiety group, the Fear of Negative Evaluation Scale (FNE) scores were positively related to the recall of positive social “to-be-remembered” words, and negatively related to the recall of negative social “to-be-forgotten” words. In the control group, FNE scores were negatively related to the recall of positive social “to-be-remembered” words. These results suggest that the protective positive bias was absent in socially anxious individuals. Thus, they were more likely than nonanxious individuals to forget positive evaluative information; therefore, they were vulnerable to negative evaluation. Furthermore, people with excessive social anxiety might try hard to inhibit the recall of negative evaluation and to remember positive evaluation. In other words, they made an effort to maintain a good impression by avoiding negative evaluative information.
