本研究主要目的，為透過操弄自我聚焦注意來探討高社交焦慮者在社交評估情境中的心像反應，並釐清心像內涵與形成視野以及對焦慮情緒的影響。過去對於高社會焦慮者的負向自我心像，究竟是在社會威脅情境下，就會自發性的發生；還是只有在高社會焦慮者具有自我聚焦注意時，才會發生，目前尚未有實徵研究的探討，此為本研究最主要的研究目的。 本研究篩選出高社交焦慮組37人與低社交焦慮組36人參加實驗，受試者在接受所分派的自我聚焦注意操弄後，進行社交評估作業，並針對內在心像的內容進行進一步的調查。 研究結果發現，接受自我聚焦注意操弄的高社交焦慮者，其心像內容明顯充滿較高比例的負向訊息，且在實驗前後的焦慮情緒改變也相對較高，而未接受自我聚焦注意操弄的高社交焦慮組，以及兩組低社交焦慮組皆未觀察到較高的負向心像內容，在呈現形式以及焦慮情緒上亦無顯著的差別。 高社交焦慮者的自我心像會受到當下注意力投注狀態的影響，當越處於自我聚焦的狀態下，其心像的內容也充滿越多的負面訊息，心像呈現的方式也越傾向以被他人所觀察的形式。由於自我聚焦注意在社交焦慮症狀發展與維持上扮演相當重要的角色，故在釐清高社交焦慮者在自我聚焦注意下的心像內容，有助於選擇適當的治療策略，協助高社交焦慮者因應環境中的威脅。 / This study aimed to explore the imagery of high social anxious individuals in the social-evaluative context by manipulating self-focused attention , and also attempted to clarify the content of the imagery, the perspective formed by the context, and the influence on the anxiety emotion. The past studies on the issues of whether the negative self-imagery of high social anxious individuals spontaneously occurred in a social threat context or only occurred in the self-focused attention have not carried out any empirical research so far, and thus it is the main research purpose of this study. In this study, 37 high and 36 low social anxious individuals were selected to conduct the experiment. After being manipulated the self-focused attention according to the groups to which they had been assigned, the participants had to engage in a social evaluation task, and a further investigation would be undertaken according to their content of inner imagery obtained in the task. The research results showed that high social anxious individuals being manipulated the self-focused attention apparently had a higher proportion of negative messages in their content of imagery and also had a relatively higher change in their anxiety emotion before and after the experiment. On the contrast, no higher proportion of negative messages in the content of imagery was observed in the group of high social anxious individuals that were not being manipulated the self-focused attention and in other two groups of low social anxious individuals. Similarly, there were no significant differences in the forms presented and the anxiety emotion in those groups as well. The inner imagery of high social anxious individuals would be influenced by the present status of the focus of attention. While in a higher self-focused attention, the content of imagery tends to be more negative, and tends to be observer perspective.
