【摘要】：社交焦虑个体会优先加工威胁相关的信息,对威胁性刺激存在注意偏差。本研究使用点探测范式考察了非临床社交焦虑个体对不同注视方向快乐和轻蔑表情的初始注意偏差,并使用眼动技术,通过分析眼动特征探究了后期的注意偏差特点。本研究由三个研究组成,共包括五个实验。研究一使用点探测范式,探究在注意加工过程的初始阶段,非临床社交焦虑个体对轻蔑表情的注意偏差,包括实验一和实验二。实验一考察直视的轻蔑表情,实验二考察斜视的轻蔑表情。在实验一中,还将初步考察性别差异。研究二探究非临床社交焦虑个体对快乐表情的初始注意偏差,包括实验三和实验四,分别考察直视的快乐表情和斜视的快乐表情。研究三由实验五组成,使用眼动技术,通过分析非临床社交焦虑个体浏览不同注视方向快乐和轻蔑表情的注视点个数及注视时间,考察其在注意加工后期的注意偏差特点。由实验结果得出了以下结论:1)在注意加工过程初期,相比于中性表情,非临床的社交焦虑个体更优先加工直视的轻蔑表情,即存在负性注意偏向。2)在注意加工过程初期,对直视轻蔑表情的负性注意偏向仅出现在高社交焦虑水平的女性被试中,男性被试无此表现,即负性注意偏向存在性别差异。3)在注意加工过程初期,轻蔑表情只有当与直视结合时,高社交焦虑个体才会表现出注意偏向,斜视的轻蔑表情不会引起注意偏差。4)在注意加工过程初期,相比于中性表情,低社交焦虑个体更优先加工快乐表情,存在正性注意偏向,但高社交焦虑个体对积极刺激存在加工缺陷,无此表现。5)在注意加工过程后期,相比于低社交焦虑个体,高社交焦虑个体对面孔的眼睛区域存在普遍的回避现象,表现为相对注视次数较少,相对注视时间较短,并且这种回避现象主要表现在对轻蔑直视、轻蔑斜视和快乐斜视表情的注视上。6)在注意加工过程后期,相比于快乐表情,高社交焦虑个体更避免注视轻蔑表情的眼睛区域。本研究考察了在注意加工过程的不同阶段,非临床社交焦虑个体对不同注视方向面部表情的注意偏差。一方面,这将对社交焦虑的原因探索、以及临床诊断等有潜在意义;另一方面,将有助于提高以此为基础的注意训练程序的有效性。
[Abstract]:This study uses point detection paradigm to investigate the initial attention deviation of non clinical social anxiety individuals on happy and disdainful expressions in different gaze directions, and uses eye movement techniques to explore the later attention deviation by using eye movement and analyzing eye movements. This study consists of three studies, including five experiments. A use of a point detection paradigm to explore the initial stage of the attention processing process, the attention deviation of non clinical social anxiety individuals on disdainful expressions, including experiment one and experiment two. Experiment one inspects the light contempt expression of direct vision, and experiment two examines the disdainful expression of strabismus. In the first experiment, a preliminary study of gender differences. Study two explored the initial attention deviation of non clinical social anxiety individuals on happy expressions, including experiment three and Experiment four, which examined the happy expression of direct vision and the happy expression of strabismus. Study three was made up of experiment five, using eye movement technology to analyze non clinical social anxiety individuals. Look at the number of gaze points and gaze time of the happy and disdain expressions in different gaze directions, and examine the characteristics of attention deviation in the later period of attention. The following conclusions are drawn from the experimental results: 1) in the early stages of attention to the process of processing, the non clinical social anxiety body is more preferred to process the disdainful expression of direct vision, that is, the negative sex is negative. Attention bias to.2) at the beginning of the process of attention to the process of processing, the negative attention bias toward the direct contempt expression is only in the high social anxiety level of female subjects, the male subjects have no performance, that is, negative attention biased towards the existence of gender difference.3) in the early stage of attention processing, the disdainful expression only when combined with direct vision, the high social anxiety individual only Showing attention bias, the disdainful expression of strabismus does not cause attention bias.4) in the early stages of attention processing, compared to neutral expressions, low social anxiety individuals have preferred to process happy expressions and have positive attention bias, but high social anxiety individuals have additive defects on active stimulation, and no.5) in the later period of attention to the process of processing. Compared to the low social anxiety individuals, there is a general avoidance phenomenon in the eye area of the high social anxiety individuals, which shows that the number of relative fixations is less and the relative fixation time is shorter, and this avoidance phenomenon is mainly manifested in the.6 of contempt, disdainful strabismus and happy strabismus, in the later period of attention processing. On happy expressions, individuals with high social anxiety avoid looking at the eye areas of disdainful expression. This study examines the attention deviations of non clinical social anxiety individuals on facial expressions in different gaze directions at different stages of attention processing. On the one hand, it will be of potential significance for the exploration of social anxiety, and the clinical diagnosis. On the one hand, it will help to improve the effectiveness of the training program based on this.
