Cluster analysis of data from 166 children with autistic spectrum disorders revealed 4 subtypes with differences in behavioral and cognitive areas. The four subtypes include a typically autistic group, a low-functioning group, a high-functioning group (Asperger syndrome/schizoid), and a hard-to-diagnose group with mild/moderate retardation and a…

Hughes, Claire – Journal of Autism and Developmental Disorders, 1996
Subjects with autism (n=36) were assigned a simple "reach, grasp, and place" task.

Woodyatt, Gail; Ozanne, Anne – Journal of Autism and Developmental Disorders, 1992
The communicative behaviors of 6 girls with Rett syndrome (ages 2-13) were evaluated. Findings indicated that all subjects were at a preintentional level of communication, which was consistent with their profound intellectual disability and their lack of demonstration of "means-end" behavior beyond Piagetian Sensorimotor Stage III.…

Sicotte, Charles; Stemberger, Ruth M. T. – Journal of Autism and Developmental Disorders, 1999
This study sought to differentiate pervasive developmental disorder not otherwise specified (PDDNOS) from similar nonautistic disorders on the basis of a cognitive deficit, theory of mind (ToM), which is the ability to infer mental states in others, a deficit highly prevalent in autism, a disorder similar to PDDNOS. Results suggest that children…

Braverman, Mark; And Others – Journal of Autism and Developmental Disorders, 1989
The study of affect comprehension in 15 children with pervasive developmental disorders (ages 7-10) and normal children matched for mental age found that the disabled children were impaired on affect matching compared to the controls and were impaired on face and affect matching relative to their own performance on object matching.

Siegel, Bryna; And Others – Journal of Autism and Developmental Disorders, 1986
A method for empirical classification of autistic and autisticlike children, based on behavior observations of 35 males and 11 females (ages 4-28 years) was examined. Factor and cluster analysis indicated four subtypes, characterized by perseverative thinking and play, motor disturbances, schizotypal/schizoid features, and anxiety and negativism.…

Anderson, Lowell T.; And Others – Journal of Autism and Developmental Disorders, 1992
Parents of 42 children (ages 2-32) with Lesch-Nyhan disease were questioned concerning the subjects' behavior patterns. Grouping of responses into nine categories of cognitive skills indicated that only one boy showed any significant cognitive impairment. Despite evidence of good cognitive and emotional skills, subjects were academically delayed,…
