In order to comprehend how autistic children showed activity patterns at nursery school and to enable us to give early a better diagnosis and a better approach of young autistic children the “H-form Rating Scale for Handicapped Children” (HRSH) was made. This rating scale was composed of seven scales for pathology of human relationship and of twenty scales for developmental skills (self-help ability, gross motor movement, etc.) and of carrier age. A correlation matrix of 28 orders was factor analyzed. The subjects were 300 handicapped children including 45 infantile autism, 39 with autistic developmental disorders and 216 mentally retardates. Eight factors were obtained: Sociality, Attachment, Speech Disorder, Tension, Intelligence ; and also the 101 categories by the theory of quantification 111 involving Rutter's criteria of autism were analyzed. It was showed in sample value that the subjects consisted of three layers in a horn shaped form in three mode graphs: the upper layer was clustered as an autism group, the middle layer was considered as an autistic developmental disorder, and the lower as mental retardation.
