【摘要】：孤獨癥的缺陷主要是缺乏用于社會交往的非言語性行為,如目光對視、面部表情以及軀體姿勢等。其中面部表情是人類傳遞情緒信息的重要媒介,面部情緒識別能力對于個體正確并完整地了解社會性環(huán)境十分必要。因此,面部表情識別障礙嚴重影響了孤獨癥個體的人際交往和社會互動。在Gepner的孤獨癥快速視-動覺整合缺陷綜合癥和Nuske等人提出的一般領(lǐng)域加工與特殊領(lǐng)域加工關(guān)聯(lián)模型的基礎(chǔ)上,本研究分別從面部表情呈現(xiàn)強度和面部表情呈現(xiàn)速度兩個方面設(shè)計兩個實驗,以考察面部表情刺激材料的特征對孤獨癥兒童面部表情識別障礙的影響。 實驗一,向被試呈現(xiàn)不同情緒強度的情緒面孔刺激來探究不同情緒強度和不同情緒類型的情緒面孔對孤獨癥的面部表情識別是否有影響。結(jié)果發(fā)現(xiàn)被試類型主效應(yīng)顯著,正常組的表情識別反應(yīng)時和正確率顯著小于孤獨癥組,說明孤獨癥個體在識別面部表情時有一定的障礙；結(jié)果還發(fā)現(xiàn),情緒類型主效應(yīng)顯著,個體對快樂表情的識別的反應(yīng)時顯著小于對憤怒表情的識別；面部表情的強度主效應(yīng)顯著,且100%強度表情的識別反應(yīng)時顯著小于50%強度表情的識別。 實驗二,向被試呈現(xiàn)不同速度的面孔情緒刺激來探究情緒呈現(xiàn)速度和不同情緒類型對孤獨癥的面部表情是否有影響,結(jié)果發(fā)現(xiàn),正常組被試在面部表情呈現(xiàn)速度較快(600ms)的情況下,反應(yīng)時最小,面部表情的識別最好；然而,與之相反的是,孤獨癥被試在呈現(xiàn)速度較慢(1800ms)的情況下,面部表情的識別最好。事后多重比較發(fā)現(xiàn),孤獨癥組對1800ms呈現(xiàn)的面部表情識別顯著快于600ms和1200ms的呈現(xiàn)速度。即孤獨癥被試在情緒面孔的呈現(xiàn)速度越慢的情況下,對面部表情的識別越好。 最后,從研究方法和刺激材料的生態(tài)效度等方面反思了本研究的不足,并對未來的研究方向進行了展望,也對本研究的理論意義和現(xiàn)實意義進行了探討。
[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.
