【摘要】：目的：社交焦慮是一種危害人類心理健康的嚴(yán)重心理問題，信息加工偏差對社交焦慮的發(fā)生發(fā)展有重要影響。社交焦慮者的這種偏差可以劃分為注意偏差、記憶偏差、消極自我意象和解釋偏差等認(rèn)知偏差，其中對威脅信息的注意偏差在社交焦慮的發(fā)生發(fā)展中具有重要作用。在社交情境中，與社交焦慮特異相關(guān)的威脅信息包括威脅性面孔和注視方向。目前關(guān)于社交焦慮的這種注意偏向效應(yīng)還未得到一致的結(jié)論，并且前人的研究多數(shù)只研究面部表情和注視方向兩個因素中的一個，然而面部表情和注視方向往往共同作用影響認(rèn)知加工過程，兩者共同作用對社交焦慮的信息加工產(chǎn)生怎樣的影響尚不清楚，其背后的機(jī)制也未得到研究。因此，本研究采用眼動技術(shù)和事件相關(guān)電位技術(shù)研究注視方向與面部表情的交互作用對社交焦慮個體信息加工過程的影響，探討其相互作用的行為學(xué)證據(jù)和電生理機(jī)制。方法：研究一：使用Liebowitz社交焦慮量表(LSAS)篩查安徽醫(yī)科大學(xué)本科生，根據(jù)LSAS量表得分將56名被試分為高社交焦慮組（HSA）和低社交焦慮組（LSA），采用配對的厭惡和中性面孔作為實驗刺激材料并記錄眼動數(shù)據(jù)。 研究二：使用Liebowitz社交焦慮量表(LSAS)篩查安徽醫(yī)科大學(xué)本科生，根據(jù)LSAS量表得分將40名被試分為高社交焦慮組（HSA）和低社交焦慮組（LSA），采用憤怒和中性面孔作為實驗刺激材料，記錄行為學(xué)數(shù)據(jù)與事件相關(guān)電位數(shù)據(jù)。結(jié)果：研究一：直視條件下，HSA組注視厭惡面孔的時間為（2311.09±521.41）ms,注視中性面孔的時間為（1910.69±607.59）ms,差異具有統(tǒng)計學(xué)意義（P 0.05），LSA組注視厭惡面孔與中性面孔的時間差異無統(tǒng)計學(xué)意義（P0.05）；斜視條件下，HSA與LSA注視厭惡面孔與中性面孔的時間差異均無統(tǒng)計學(xué)意義（P0.05）。 研究二：在ERP結(jié)果中，注視方向主效應(yīng)顯著(F(1,38)=12.42, P=0.001)，直視誘發(fā)更大的N300波幅(M=1.880,SE=0.43)。組別主效應(yīng)顯著(F (1,38)=6.54,P=0.01)，高社交焦慮個體(M=0.972, SE=0.61)比低社交焦慮個體(M=3.19, SE=0.61)誘發(fā)更大的N300波。電極點(diǎn)主效應(yīng)顯著(F (1,38)=136.79, P=0.000.)，N300波幅在前中部電極點(diǎn)最大(FZ: M=0.27, SE=0.43)。情緒×注視方向×組別交互效應(yīng)顯著(F (1,38)=5.00, P=0.03)。簡單效應(yīng)分析發(fā)現(xiàn)，高社交焦慮組情緒×注視方向交互效應(yīng)顯著(F(1,38)=5.98, P=0.02)，低社交焦慮個體交互效應(yīng)不顯著(F(1,38)=0.23, P=0.64)。進(jìn)一步研究發(fā)現(xiàn)，高社交焦慮個體注視方向效應(yīng)在憤怒情緒條件下(F (1,38)=15.36, P=0.001)顯著，在中性情緒條件下(F(1,38)=0.009, P=0.92)不顯著。直視(M=0.44, SE=0.74)比斜視(M=2.02, SE=0.72)引起更大的N300波幅。兩組被試行為學(xué)數(shù)據(jù)差異無統(tǒng)計學(xué)意義（P0.05）。 結(jié)論：研究一：注視方向影響了社交焦慮個體對厭惡表情的加工，，表明直視的厭惡面孔對于HSA個體來說是一種社交威脅信息,斜視的厭惡面孔不是明確的社交威脅信息。 研究二：高社交焦慮個體直視的憤怒面孔比斜視的憤怒面孔誘發(fā)更大的N300波。注視方向不影響中性面孔的加工。低社交焦慮個體未表現(xiàn)出注視方向和面部情緒的交互效應(yīng)。
[Abstract]:Objective: social anxiety is a serious psychological problem that endangers the mental health of human beings. Information processing deviations have an important influence on the development of social anxiety. These deviations can be divided into cognitive deviations, such as attention deviation, memory deviation, negative self image and interpretation deviation, among which the attention deviation to the threat information is found. Social anxiety has an important role in the development of social anxiety. In social situations, threats related to social anxiety include threatening faces and gaze directions. The current attention bias effect on social anxiety has not yet been agreed, and previous studies have only studied two causes of facial expression and fixation. One of the elements, however, the facial expression and the direction of fixation often affect the process of cognitive processing. It is not clear how the interaction of the two effects on the information processing of social anxiety is not clear, and the mechanism behind it has not been studied. Therefore, this study uses eye movement technology and event related potential technology to study the direction and face of the face. The effect of facial expression interaction on the process of information processing of social anxiety individuals, the behavioral evidence and electrophysiological mechanism of their interaction. Methods: Study 1: the Liebowitz social anxiety scale (LSAS) was used to screen the undergraduates of Medical University Of Anhui, and 56 subjects were divided into high social anxiety group (HSA) and low social society according to the LSAS scale score. In the anxiety group (LSA), paired aversion and neutral faces were used as experimental stimuli and recorded eye movement data.
Study two: using the Liebowitz social anxiety scale (LSAS) to screen undergraduate students from Medical University Of Anhui, 40 subjects were divided into high social anxiety group (HSA) and low social anxiety group (LSA) according to the LSAS scale score. Anger and neutral face were used as experimental stimulus materials, and behavioral data and event related potential data were recorded. Under the condition of direct vision, the time for the HSA group to look at the disgust face was (2311.09 + 521.41) ms, the time for looking at the neutral face was (1910.69 + 607.59) ms, and the difference was statistically significant (P 0.05). The time difference between the disgust face and the neutral face in the LSA group was not statistically significant (P0.05). Under the strabismus condition, HSA and LSA watched the aversion face and neutral face with LSA. The time difference was not statistically significant (P0.05).
Study two: in the results of ERP, the main effect of gaze direction is significant (F (1,38) =12.42, P=0.001), and direct vision induces a greater N300 amplitude (M=1.880, SE=0.43). The main effect of the group is significant (F (1,38) =6.54, P=0.01), and the higher social anxiety individuals are more than the low social anxiety individuals. (F (1,38) =136.79, P=0.000.), N300 amplitude was maximum (FZ: M=0.27, SE=0.43) in the anterior central area (FZ: M=0.27, SE=0.43). The interaction effect of mood X direction X group was significant (F (1,38) =5.00, P=0.03). No significant (F (1,38) =0.23, P=0.64). Further studies have found that the gaze direction effect of high social anxiety individuals (F (1,38) =15.36, P=0.001) is significant in angry mood conditions (F (1,38) =0.009, P=0.92) is not significant in neutral mood conditions. There was no statistical difference in the difference of the data (P0.05).
Conclusion: Study 1: the direction of gaze affects the processing of social anxiety individuals on disgust expression, indicating that the disgust face of direct view is a social threat to HSA individuals, and the disgust face of strabismus is not a clear social threat.
Study two: the angry face directly viewed by high social anxiety individuals increased the N300 wave more than the angry face of the strabismus. The direction of fixation did not affect the processing of neutral faces. The low social anxiety individuals did not show the interaction effect of the direction of fixation and the facial emotion.
