Restricted or repetitive behavior (RRB) is common for individuals with visual impairment (VI), autism spectrum disorder (ASD), and intellectual disability. Previous reviews have suggested that VI may moderate the effectiveness of behavioral interventions to decrease RRB. A search of the single case literature resulted in 30 studies and 40…

There exists now a body of research that describes case studies of individuals with autism spectrum disorder (ASD) who have engaged, or are alleged to have engaged, in a range of illegal behaviours, and that attempts to estimate the prevalence of ASD at different stages of the criminal justice process. Taken together, this research does suggest…

Studies assessing sex/gender differences in autism spectrum conditions often fail to include typically developing control groups. It is, therefore, unclear whether observed sex/gender differences reflect those found in the general population or are particular to autism spectrum conditions. A systematic search identified articles comparing…

Studies are reviewed that support the hypothesis that infantile autism results from a neuropathology of the temporal lobes of the brain. It is concluded that the main autistic symptoms are most consistent with a neurological model involving bilateral dysfunction of the temporal lobes. (Author)

Findings from a review of recent empirical studies on autism in the areas of behavioral characteristics (stimulus overselectivity, echolalia, imitation) and treatment interventions (social language development, stereotypic behavior, instructional design) are presented. (Author/CL)

This paper summarizes the case histories of four young children with concurrent autistic disorder and Williams syndrome. Williams syndrome comprises a peculiar facial appearance, learning disorder, and often hypercalcemia, mild microcephaly, large blood vessel stenosis, and a specific behavioral phenotype. Literature on Williams syndrome is…

The author reviews recent literature dealing with teaching autistic children acceptable behaviors. Using E. Ornitz and E. Ritvo's description of autism, teaching procedures to overcome weaknesses in perceptual difficulties, bizarre movement, and problems in relating are discussed. (CL)

This article introduces some approaches that educational practitioners can use to assess the academic skills of students with Asperger syndrome (AS), while emphasizing the need for a comprehensive assessment system involving both formal and informal assessment methods as part of educational interventions. Academic characteristics of students with…

Demonstrates that young autistic children suffer from deficits in social understanding and symbolic representations of other individuals. Data suggest that the core deficit appears to lie at the intersection of representational abilities and social experiences. (RWB)

The paper presents an overview of an ethological approach to the study of abnormal human behavior and a review of research using ethological approaches (with an emphasis on autism research). Ethology is defined as the study of behavior as it occurs in its natural habitat. The four types of questions ethologists ask about behavior, such as what is…

This paper reviews the research on fragile X syndrome, the second most common cause of mental retardation related to chromosomal anomaly. It notes that far more males than females are affected by the fragile X syndrome, which typically results in craniofacial changes, delays in growth and development, speech/language difficulties, and cognitive…

This book is intended as an eclectic review and overview of what is known about autism, emphasizing clinical, rather than theoretical, aspects of the syndrome. Eleven chapters address the following topics: (1) definition of autism (myths, definitions, and facts about autism); (2) diagnosis of autism (medical versus educational diagnosis); (3)…
