Brief report: two case studies using virtual reality as a learning tool for autistic children.

The children complied with most requests. Some of our teaching goals were limited by technology or space while others were limited by the difficulty of presenting a task to the children in a way that was understandable within their environment. However, the opportunity to introduce this technology to children was an important first step in exploring the potential VR offers to understanding the perceptual processes involved in autism. Our results indicate that the will accept a VR helmet and wear it, identify familiar objects and qualities of these objects in their environment while using the helmet, and locate and move toward objects in their environment while wearing the helmet. More research is necessary to verify the potential in this area, especially to discover if learning experiences through VR generalize to other environments, but it appears virtual reality may provide a useful tool for furthering our understanding of autism and guiding efforts at treatment and intervention.

Comparison of DSM-III-R and childhood autism rating scale diagnoses of autism.

The purpose of this study was to clarify the issue of whether DSM-III-R (American Psychological Association [APA], 1987) over- or underdiagnoses autism by comparing this diagnostic system to a well-established objective measure of diagnosis, the Childhood Autism Rating Scale (CARS). A secondary goal was to determine which of the 16 criteria are the best discriminators of autism. DSM-III-R, CARS, and clinical diagnoses of 138 consecutive admissions to a statewide program for the diagnosis and treatment of autistic and related communication-handicapped individuals (Division TEACCH in North Carolina) were compared. Results indicated a generally high degree of agreement on the diagnosis of autism using the three systems. Within this treatment-oriented program, the CARS and clinical ratings diagnosed a greater number of cases as autistic than did the DSM-III-R criteria, suggesting that DSM-III-R slightly underdiagnosed autism. The criteria that most strongly related to the diagnosis of autism regardless of the system were lack of awareness of others, abnormal social play, an impaired ability to make friends, abnormal nonverbal communication, stereotypic body movements, and restricted range of interests.

The social and symbolic quality of autistic children's communication.

The developmental status of the communicatory behavior of 11 autistic children was assessed. Children were observed during free play sessions under two conditions: when teachers were present to direct the children's behavior and when teachers were absent and the children played among themselves. Mean changes in the children's communicatory behavior were measured over time (8 months) using the behavior scale designed for this study. The relationship between the developmental status of the children's communicatory behavior and standardized measures of their social and cognitive functioning (e.g., IQ, Vineland Social Age) was also assessed. The results revealed that the quantity and social quality of autistic children's communicatory behavior were greater in the teachers' presence than in their absence and that the symbolic and social quality of the children's communicatory behavior increased over 8 months. Also, positive correlations were found between social and symbolic levels of communication and standardized tests of social and cognitive functioning. The implications of these findings for the assessment of autistic children are discussed.

Patterns of coping in families of psychotic children.

The nature of family adaptation to severely and chronically disabling cognitive and behavioral conditions is considered. The relationship between atypical development and family response is examined to derive basic concepts--parents' perceptions of their child's unusual characteristics, effects on social relationships, etc.--and suggest strategies for intervention and research.
