【摘要】：个体的情绪识别能力对其生存和发展有着举足轻重的作用,而对面部表情的识别能力又是个体情绪识别能力的一个重要表现。接收和解读他人的面部表情信息,不仅对个体的社会交往活动产生重要影响,对其心理健康更是有着深远意义。大量研究发现孤独症儿童对积极情绪面孔的识别要好于消极情绪面孔,并且他们对各种消极情绪面孔的识别存在差异,但对此得出的结论却有所不同。为探明孤独症儿童对不同消极情绪面孔的识别情况及其在面孔识别中采用的异常加工策略,本研究设计两个实验,若两个实验得到一致的结论,则本实验为当前该研究领域存在的争议提供了有力的支持。实验一采用经典的学习——再认范式,实验二利用Morph技术进行实验。从孤独症儿童康复中心招募孤独症儿童20名,年龄6-10岁。从中国化面孔情绪图片中选取10张中性情绪面孔图片,运用FaceGen、Photoshop、Sqirlz Morph2.1等软件对这些图片进行处理,整理出本实验所需要的一系列情绪面孔图片。采用Excel、E-prime自带E-merge以及SPSS16.0等数据处理软件对实验所收集的数据进行统计整理分析。实验一结果显示:孤独症儿童在本研究所涉及的四种消极情绪面孔的识别上存在显著差异,具体表现为:在四种消极情绪面孔图片中,孤独症儿童对厌恶情绪面孔图片的再认成绩最好,对恐惧情绪面孔图片的再认成绩最差。实验二得到与实验一一致的结果,表现为被试需要更高强度的恐惧情绪才能对恐惧情绪面孔图片进行识别,而在识别厌恶情绪面孔图片时,却只需要较低的情绪强度。通过对两个实验所得结果进行分析,本研究得出以下结论:孤独症儿童在四种消极情绪面孔的识别上存在显著差异,对厌恶情绪面孔的识别最好,对愤怒情绪面孔和悲伤情绪面孔的识别情况次之且对这两种情绪面孔的识别不存在差异,对恐惧情绪面孔的识别最差。
[Abstract]:The ability of individual emotion recognition plays an important role in its survival and development, and the recognition ability of facial expression is an important expression of individual emotion recognition ability. It not only has an important influence on the individual's social interaction, but also has profound significance to its mental health. A large number of studies have found that autistic children recognize positive emotional faces better than negative emotional faces. In order to find out how autistic children recognize different negative emotional faces and the abnormal processing strategies used in face recognition, there are differences in their recognition of various negative emotional faces, but their conclusions are different. In this study, two experiments are designed. If the two experiments reach a consistent conclusion, this experiment provides a powerful support for the current controversy in this field. Experiment 1 adopts the classical learning-recognition paradigm. Experiment 2: using Morph technique, 20 autistic children aged 6 to 10 years were recruited from the rehabilitation center of autistic children. Ten neutral emotional faces were selected from Chinese facial images. The images were processed using software like Facebook Photoshop Sqirlz Morph2.1. A series of images of emotional faces needed in this experiment were sorted out. Data processing software such as Excel E-prime with E-merge and SPSS16.0 were used to analyze the data collected in the experiment. The results of experiment 1 showed that autistic children were in this study. There are significant differences in the recognition of the four negative emotional faces involved. Among the four negative emotional faces, the autistic children had the best recognition scores for the disgust faces and the worst for fear faces. In order to recognize the face of fear emotion, the subjects need higher intensity of fear emotion in order to recognize the face of fear emotion, but only the lower intensity of emotion is needed when recognizing the picture of face of disgust. The results of two experiments were analyzed. This study concludes that there are significant differences in the recognition of four negative emotional faces in autistic children, and the recognition of disgust faces is the best. The recognition of angry and sad faces is second, and there is no difference between them, but the recognition of fear faces is the worst.
