In this study, the looking behavior of 16 autistic and 14 non-autistic children toward cartoon-like scenes that included a human figure was measured quantitatively using an infrared eye-tracking device. Fixation behavior of autistic children was similar to that of their age-and IQ-matched normal peers. Results do not support the idea that autistic…

Comparison of caregiver behaviors of children with either autism, developmental delay, or typical development found no difference between groups in caregiver synchronization with the child's focus of attention. Also, caregivers of children with autism who showed higher levels of synchronization during initial play interactions led to superior…

Evaluation of social-cognitive skills in 23 young children with autism or other developmental delays found tests involving others' attention were more difficult for children with autism than tests involving others' behavior. However, the typical developmental pattern of first sharing, then following, and then directing attention or behavior was…

Comparison of children and adolescents with Fragile X Syndrome (n=18) or autism (n=18) for changes in cognitive ability and adaptive behavior over 9 years found steeper decreases in IQ scores among Fragile X subjects with older autistic subjects autism exhibiting stable test-retest scores. Comparative declines in adaptive behavior scores were…

Comparison of data on all children referred for suspected autism spectrum disorder (ASD) in the Australian Capital Territory in 1997 and 1989 found a 200% increase in ASD diagnoses in 1997 despite a population decrease; a wider age range in 1997; a 26% increase in milder cases; and a decrease in the ratio of boys to girls. (Contains references.)…

This study compared children (n=68) with either autism or general delay on false belief tasks and tasks to test for an understanding of interpretive diversity. Findings partially support the view that tasks of understanding interpretive diversity are more difficult than false belief tasks. Between-group differences in the consistency and quality…

Twenty children with autism received either an imitative or contingently responsive interaction with an adult. The contingency condition appeared to be the more effective way to facilitate a distal social behavior (attention), whereas the imitative condition was a more effective way to facilitate a proximal social behavior (touching). (Contains…

A study compared 13 children (ages 5-7) with autism and 13 typical children on their ability to match videotaped still, dynamic, and strobe emotional and non-emotional facial expressions with photographs. The children with autism did not perform significantly worse than controls on any experimental conditions. (Contains references.) (Author/CR)

A study involving eight high-functioning children with autism found they could define words, identify multiple meanings for ambiguous words, and make inferences from mental state verbs to given or presupposed knowledge. However, they failed to infer what mental state verbs implied in context and to make inferences about social scripts. (Contains…

A study investigated the operationalization, the identification, and the prevalence of weak central coherence and poor cognitive shifting in 35 high-functioning adolescents with autism. Weak central coherence and poor cognitive shifting did not appear to be related to measures of symptom severity, social understanding, and social competence.…

The functional play of children with autism (n=15) was compared to that of developmentally matched children with Down syndrome (n=15) and typical infants (n=15). The functional play of the children with autism was less elaborated, less varied, and less integrated than that of the controls. (Contains references.) (Author/CR)

A study involving 47 families of individuals (ages 4-34) with autism and severe mental retardation found the familial loading for autism and for the broader phenotype was closely comparable to that in a study of children with higher IQ autism, and different from that for children with Down syndrome. (Contains references.) (Author/CR)

A study involving six boys (ages 2-9) with autism found the use of naltrexone improved social initiations on videotape samples, social scale of the Gilliam Autism Rating Scales (4 out of 6 improved), stereotypies scale of GARS (5 out of 6 improved), and attention problems (4 out of 6 improved). (Contains references.) (CR)

This study reports marked reductions in self-injurious behavior and aggression of two adults with profound mental retardation treated with clozapine, who were non-responsive to all other behavioral and psychopharmacological interventions, including risperidone. The most effective dose was 200mg/day. Side effects were mild and the drug was…

A study investigated the relations between various measures of social understanding and social interaction competence in verbally able children with autism (n=20). Initiating joint attention and empathy were strongly related measures of social interaction competence. No understanding-behavioral links were identified for 20 language-age matched…
