1. Prior studies in which static pictures were used suggest that, in face recognition, children with autism rely on the mouth region more than on the eye region. However, it is not clear whether the same tendency exists in the case of autistic adults viewing the facial expressions of animated pictures. Therefore, the reactions of two autistic adults who took part in Wakamatsu's study (2002), in which the facial expressions of computer-generated animated pictures were conveyed by movement of the whole face, by movement in the eye region and by movement of the mouth, were employed as hypotheses, and then tested for 2 groups of autistic and intellectually disabled individuals. The autistic group comprised 13 individuals with ages ranging between 19 and 35, and the intellectually disabled group was made up of an equal number of people, with ages ranging between 18 and 32. The results indicated that the autistic individuals' reactions tended to be more similar to the hypotheses as compared to the reactions of the intellectually disabled individuals, and that autistic adolescents and adults also have the above-mentioned tendency to rely on the mouth region in face recognition.2. In this study, I report the development of a computer-based program to teach the ability to identify basic facially expressed emotions using computer-generated animated pictures. The treatment group comprised 11 autistic individuals with ages ranging between 9 and 28, and the no-treatment control group was made up of 16 autistic people, with ages ranging between 10 and 32. The training was conducted for 2-4 sessions. The trained individuals improved significantly on the affect recognition task. Results support the usefulness of the program to teach the detection of facial affect. On the other hand, a few changes demonstrated on parent and teacher ratings of recognition and production of facial expressions in everyday life.

1.先前使用静态图片的研究表明，在人脸识别中，自闭症儿童更多地依赖嘴部区域，而不是眼睛区域。然而，目前尚不清楚自闭症成年人观看动画图片的面部表情时是否存在同样的倾向。因此，参与Wakamatsu的研究(2002)的两名自闭症成年人的反应被作为假设，然后对两组自闭症和智力障碍的人进行测试。在这项研究中，计算机生成的动画图片的面部表情通过整个面部的运动、眼睛区域的运动和嘴巴的运动来传达。自闭症组由13个人组成，年龄在19岁到35岁之间，智力障碍组由同样数量的人组成，年龄在18岁到32岁之间。研究结果表明：1.与智障个体相比，自闭症个体的反应倾向于更接近于假设，自闭症青少年和成人在面孔识别上也有依赖口部的倾向。在这项研究中，我报告了一个基于计算机的程序的开发，该程序旨在教授使用计算机生成的动画图片识别基本面部表情的能力。治疗组包括11名自闭症患者，年龄在9岁到28岁之间，未接受治疗的对照组由16名自闭症患者组成，年龄在10岁到32岁之间。训练时间为2-4个疗程。受过训练的个体在情感识别任务上有了显著的提高。结果支持该程序在教授面部情感检测方面的有效性。另一方面，家长和老师对日常生活中面部表情的识别和产生的评分出现了一些变化。
