【摘要】:自我概念清晰性是個(gè)體對(duì)自我概念了解的清楚程度,受自我威脅的影響.杏仁核是威脅信息加工的重要腦區(qū),該區(qū)域的異常在特質(zhì)焦慮等焦慮個(gè)體中均有所體現(xiàn).雖然,目前缺乏杏仁核與自我概念清晰性之間關(guān)系的直接證據(jù),但是通過研究特質(zhì)焦慮-杏仁核-自我概念清晰性的關(guān)系,或許可以有助于進(jìn)一步理解二者之間的關(guān)系.本研究基于體素的形態(tài)學(xué)分析(VBM)技術(shù),在研究杏仁核與特質(zhì)焦慮關(guān)系的基礎(chǔ)上,探討杏仁核對(duì)自我概念清晰性的預(yù)測作用.結(jié)果表明,特質(zhì)焦慮和自我概念清晰性呈顯著負(fù)相關(guān);VBM分析發(fā)現(xiàn),基底外側(cè)杏仁核的區(qū)域灰質(zhì)體積與特質(zhì)焦慮顯著正相關(guān),而且該區(qū)域可以顯著預(yù)測個(gè)體的自我概念清晰性水平.這些結(jié)果共同說明,隨著杏仁核體積的增大,個(gè)體更易于受到自我威脅的影響,進(jìn)而表現(xiàn)出較低的自我概念清晰性.
[Abstract]:The clarity of self-concept is the degree of understanding of self-concept, which is influenced by self-threat. Amygdala is an important brain area for the processing of threat information, and the abnormality of this area is reflected in anxiety individuals such as trait anxiety. Although there is no direct evidence of the relationship between amygdala and self-concept clarity, studying the relationship between trait anxiety, amygdala and self-concept clarity may be helpful to further understand the relationship between them. Based on the morphologic analysis of voxel (VBM) and the relationship between amygdala and trait anxiety, this study explored the predictive effect of amygdala nucleus self-concept clarity. The results showed that there was a significant negative correlation between trait anxiety and self-concept clarity. VBM analysis showed that the regional gray matter volume of the basal lateral amygdala was positively correlated with trait anxiety. Moreover, the region can significantly predict the level of self-concept clarity of an individual. These results suggest that with the increase of amygdala volume, individuals are more vulnerable to self-threat, and thus show lower self-concept clarity.
