高社交焦慮者在指示遺忘作業之回憶表現--從遺忘觀點探討記憶偏誤 / Memory Bias in Socially Anxious Individuals: A Perspective from Directed Forgetting林肇賢, LIN, CHAO-HSIEN Unknown Date (has links)
本研究主要目的在於運用指示遺忘作業探討高社交焦慮者是否有記憶偏誤現象。高社交焦慮組24人與低社交焦慮組20人參與正式實驗,受試者被要求依據指示記住或忘記三種類型刺激詞(社交威脅、中性、社交正向)。作業結果未發現任何顯著之組間差異,但進一步分析發現,在指示記住項目的回憶上,所有受試者皆回憶出較多的社交正向詞(相對於中性詞以及社交威脅詞),顯示記憶的正向偏誤,然而,在指示忘記項目的回憶上,正向偏誤的現象僅出現在低社交焦慮組,不見於高社交焦慮組。此外,相關分析顯示,高社交焦慮組的FNE量表(Fear of Negative Evaluation Scale)得分與指示記住的社交正向詞回憶量成正相關,與指示忘記的社交威脅詞回憶量成負相關;低社交焦慮組的FNE量表得分與指示記住的社交正向詞回憶量成負相關。這些結果顯示高社交焦慮者可能缺乏正向偏誤的保護機制,較一般人更容易遺忘正向評價訊息,因而更容易受到負面評價的影響,於是他們傾向抑制負向評價訊息的回憶,將注意力投注在非威脅訊息,並努力記住正向評價,換言之,他們透過逃避負面評價的方式來維持良好的自我形象。 / 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.

高社交焦慮者的自傳式記憶特性--關於記憶清晰度的探討梁記雯 Unknown Date (has links)
本研究的主要目的在於運用自傳式記憶的作業探討高社交焦慮者是否有記憶偏誤的現象。根據Clark和Wells(1995)的模型,高社交焦慮者在社交焦慮情境中容易把大部分的注意力集中在自身相關(self-related)的訊息上,因而造成對自身相關訊息的記憶優於外界環境訊息的現象;然而根據Repee和Heimberg(1997)的模型則假設高社交焦慮者在社交情境中會關注與負向自我評價有關的訊息,而不論該訊息是來自自身或外界環境。本研究企圖同時檢測上述兩個模型。
本研究篩選出六十四名大學生分為高社交焦慮與低社交焦慮兩組,所有受試者皆須分別回憶一件社交焦慮事件及一件中性事件,受試者被要求先在腦海中形成對該事件的影像,然後寫下有關回憶事件的詳細描述並完成記憶清晰度的評估。
研究結果得出高社交焦慮者在進行社交焦慮事件的回憶時,傾向回憶出比低社交焦慮組更多的自身相關訊息;且高社交焦慮組在回憶社交焦慮事件時比低社交焦慮組更傾向評估自身相關訊息的記憶清晰度高於外界環境訊息,研究結果較支持Clark和Well(1995)的說法。 / The purpose of the present study was to utilize the autobiographical memory task to investigate the memory bias in socially anxious individuals. According to Clark and Wells’ (1995) view, socially anxious individuals were hypothesized to preferentially allocate almost attentional resources to self-related information and remember self-related information better than external information on entering an anxiety-provoking social situation. However, according to Repee and Heimberg’ s (1997) model, they supposed that socially anxious individuals tend to focus on negative self-evaluated information regardless of it were self-related or external information. The present study tried to examine the two models simultaneously.
Sixty-four undergraduate students were assigned to either high or low social-anxiety group. All subjects were asked to recall one anxiety-provoking social situation about public-speaking and another neutral situation. They were requested to form an image of the event and write a detailed description about it. They then completed rating of memory vividness for each situation.
The results revealed that high social anxiety group showed to retrieve more self-related information than low social anxiety group and displayed more preferential to rate the vividness of self-related information higher than external environmental information than low social anxiety group did when recalling anxiety-provoking social situation. The result supported Clark and Wells’ s model.
