【摘要】：孤独症的缺陷主要是缺乏用于社会交往的非言语性行为,如目光对视、面部表情以及躯体姿势等。其中面部表情是人类传递情绪信息的重要媒介,面部情绪识别能力对于个体正确并完整地了解社会性环境十分必要。因此,面部表情识别障碍严重影响了孤独症个体的人际交往和社会互动。在Gepner的孤独症快速视-动觉整合缺陷综合症和Nuske等人提出的一般领域加工与特殊领域加工关联模型的基础上,本研究分别从面部表情呈现强度和面部表情呈现速度两个方面设计两个实验,以考察面部表情刺激材料的特征对孤独症儿童面部表情识别障碍的影响。 实验一,向被试呈现不同情绪强度的情绪面孔刺激来探究不同情绪强度和不同情绪类型的情绪面孔对孤独症的面部表情识别是否有影响。结果发现被试类型主效应显著,正常组的表情识别反应时和正确率显著小于孤独症组,说明孤独症个体在识别面部表情时有一定的障碍；结果还发现,情绪类型主效应显著,个体对快乐表情的识别的反应时显著小于对愤怒表情的识别；面部表情的强度主效应显著,且100%强度表情的识别反应时显著小于50%强度表情的识别。 实验二,向被试呈现不同速度的面孔情绪刺激来探究情绪呈现速度和不同情绪类型对孤独症的面部表情是否有影响,结果发现,正常组被试在面部表情呈现速度较快(600ms)的情况下,反应时最小,面部表情的识别最好；然而,与之相反的是,孤独症被试在呈现速度较慢(1800ms)的情况下,面部表情的识别最好。事后多重比较发现,孤独症组对1800ms呈现的面部表情识别显著快于600ms和1200ms的呈现速度。即孤独症被试在情绪面孔的呈现速度越慢的情况下,对面部表情的识别越好。 最后,从研究方法和刺激材料的生态效度等方面反思了本研究的不足,并对未来的研究方向进行了展望,也对本研究的理论意义和现实意义进行了探讨。
[Abstract]:The main defect of autism is the lack of non-verbal behavior used in social communication, such as eye, facial expression and body posture, among which facial expression is an important medium for human to transmit emotional information. Facial emotion recognition is essential for individuals to understand the social environment correctly and completely. Facial expression recognition disorder seriously affects the interpersonal and social interaction of autistic individuals. Based on the association model of general domain processing and special domain processing proposed by Gepner's autism rapid visual and kinesthetic integration deficiency syndrome and Nuske et al. In this study, two experiments were designed from two aspects of facial expression intensity and facial expression presentation speed to investigate the effect of facial expression stimulation material on facial expression recognition disorder in autistic children. In the first experiment, the subjects were given different emotional facial stimuli with different emotional intensities to explore whether the emotional faces of different emotional intensity and different emotional types had an effect on the facial expression recognition of autism. The results showed that the main effect of the subjects was significant. The response time and correct rate of facial expression recognition in normal group were significantly lower than those in autism group, indicating that there were some obstacles in recognition of facial expression in autistic individuals, and the results also showed that the main effect of emotion type was significant. The response time of the individual to the recognition of happy expression was significantly less than that of the angry expression, and the intensity of facial expression was significant, and the recognition time of 100% intensity expression was significantly less than 50% of the intensity expression. In experiment two, the subjects were given different facial emotional stimuli at different speeds to find out whether the speed of emotional presentation and the different types of emotions had an effect on the facial expressions of autism. In the normal group, the reaction time was the least and the facial expression recognition was the best when the facial expression presented faster than 600 Ms; however, in contrast, the autistic subjects showed a slower speed of 1 800 Ms). Facial expression recognition was the best. After multiple comparisons, it was found that the face expression recognition of 1800ms in autistic group was significantly faster than that of 600ms and 1200ms. That is, the slower the emotional face, the more slowly the autistic subjects presented their emotional faces. The better the recognition of facial expressions. Finally, the deficiency of this study is reflected from the aspects of the research methods and the ecological validity of the stimulant materials, and the future research direction is prospected, and the theoretical and practical significance of this study is also discussed.
