This is a psychophysiological study to investigate developmentally retarded persons' (autistic persons') ability to recognize a person's face by using event related potentials (face-related potentials) which has been recently known as a type of evoked brain potentials specifically induced by a person's face.In fiscal 1997 and 1998, the basic characteristics of face related potentials and best condition for the measurement of face-related potentials in developmentally retarded persons were investigated. The development (6-12 years old) in the face-related potentials were investigated by using this conditions. The results suggest that (1) N170s which were especially evoked by human faces were observed in all children, and their latency became shorter and amplitude became lower with age, and (2) N170 of children was divided into N170 and N270 which was effected by face familiarity with age.In fiscal 1998 and 1999, we measured autistic patients' face-related potentials and these data were compare with the developmental data and discussed. The results demonstrated that autistic persons could not clearly distinguish a person's face from an animal's according to the data obtained from N170 and N270 components and that the pattern of autistic patients' face-related potentials obtained from right and left sides of the brain were almost the reverse of that of normal volunteers' potentials from both sides of the brain. Autistic persons were disabled the information processing of face recognition unit which proposed by Bruce & Young (1989).In next step of study, we will try the development of a new test method of the face recognition function by face-related potentials and investigate the method of improving their interpersonal relations disturbance.

这是一项心理生理学研究，旨在探讨发展性弱智者的（自闭症患者）通过使用事件相关电位识别人脸的能力最近已知的一种由人的面部特异性诱发的脑诱发电位（面部相关电位）。在1997和1998财政年度，探讨了发育迟缓者面孔相关电位的基本特征和最佳测量条件。在此条件下，研究了6-12岁儿童面孔相关电位的发展。结果表明：（1）所有儿童均存在人脸诱发的N170，其潜伏期随年龄的增长而缩短，波幅随年龄的增长而降低;（2）儿童的N170分为N170和N270，这两种N270受人脸熟悉程度的影响。本研究对孤独症患者的面孔相关电位进行了测量，并与正常儿童的面孔相关电位进行了比较和讨论。结果表明，孤独症患者不能根据N170和N270成分的数据清楚地区分人和动物的面孔，孤独症患者左右脑的面孔相关电位模式与正常志愿者左右脑的面孔相关电位模式几乎相反。自闭症患者对布鲁斯和杨（Bruce & Young，1989）提出的人脸识别单元的信息处理能力存在障碍，下一步研究将尝试开发一种新的人脸相关电位人脸识别功能测试方法，并探讨改善其人际关系障碍的方法。
