A meta-analysis was performed on the 133 cognitive and behavioral papers in autism using comparison groups in the 1999-2002 period. High-functioning (average IQ: 84.7), adolescents (average, 14.4 years) are largely dominant. IQ is the most frequent matching variable in use (51.2%). The instruments that are most frequently used to determine IQ or…

Children (ages 7-12) were invited to carry out two tasks. Sabotage resulted in the experimenter appearing to have a false belief. Whereas children with pervasive developmental disorder not otherwise specified (n=12) corrected the false belief in the rewarded task condition, children with autism (n=10) were not influenced by task condition.…

A study involving 18 high-functioning children (ages 8-17) with autism and 17 controls found that those with autism revealed a good understanding of social interaction and loneliness and demonstrated a high level of social initiation. They spent only half the time in social interactions with peers, however, compared to controls. (Contains…

A study involving four children (ages 4-7) with developmental disabilities and severe opposition behaviors found that use of reinforcement for compliance in isolation was ineffective in bringing about significant improvement in child compliance. The addition of a graduated request hierarchy appeared to be associated with substantial changes in…

A study involving three men with autism examined the effects of allowing the men to make their own activity schedules by writing down the order of their tasks. Social praise was provided contingent on the participant's task completion. Client engagement was substantially higher than baseline for all three participants. (Contains references.)…

A study examined the narrative abilities of 28 high-functioning children (ages 8-14) with autism or Asperger syndrome and 22 controls across two different discourse contexts. Compared to controls, the subjects performed relatively well in the storybook context but exhibited difficulty imbuing their narratives of personal experience with more…

A study investigated the ability of 8 adolescents with Asperger syndrome or high-functioning autism to pick funny endings for cartoons and jokes. The adolescents with autism had significantly poorer comprehension of cartoons and jokes than age-matched controls. Both subjects and controls had more difficulty with the joke task. (Contains…

The atypical antipsychotic medication risperidone was evaluated using a double-blind, placebo-controlled design to treat destructive behavior in two males (ages 6 and 24) with autism. Destructive behavior during the demand condition was significantly reduced during the medication phases, whereas it continued to occur to obtain tangible items and…

Thirty-six mothers of children with autism rated videotapes of behavior from young children later diagnosed with autism who were then assigned to a diagnostic or a no-diagnostic information group. No differences were found on overall ratings of intentionality. Mothers in the diagnostic information group rated stereotyped behavior as less…

A study examined the cognitive underpinnings of spontaneous and prompted pretend play in 28 children with autism (ages 2-3), 24 children with developmental disorders, and 26 controls (ages 1-3). Children with autism were significantly delayed on pretend play scores. They also had significant deficits in a theory of mind measure. (Contains…

A study investigated the accuracy and speed of face recognition in 26 children (ages 7-10) with Pervasive Developmental Disorder Not Otherwise Specified. Subjects needed an amount of time to recognize the faces that almost equaled the time they needed to recognize abstract patterns that were difficult to distinguish. (Contains references.)…

The agreement between the Autism Diagnostic Interview-Revised (ADI- R) and the Childhood Autism Rating Scale (CARS) was investigated in the diagnostic assessment of 54 children (ages 22-114 months) referred for possible autism. The observed agreement between the two systems was 66.7%. The CARS identified more cases of autism than the ADI-R.…

Nonverbal IQs were greater than verbal IQs for children (ages 3-7) on the Stanford-Binet: IV (n=53). However, WISC-III verbal and nonverbal IQs were similar for older children, 6-15 years of age (n=63). Stanford-Binet: IV profiles were generally consistent for the low-IQ and high-IQ groups with high scores on visual matching tests. (Contains…

This article describes an individual (age 49) with mental retardation who experienced behavioral exacerbation associated with clonazepam prescribed at 2 mg/day to treat aggression, self-injurious behavior, property destruction, and screaming. When clonazepam was reduced and discontinued, these behaviors significantly decreased from 3.1% of…

This article discusses the problem of over-including individuals in the autism classification. It argues that clinicians are doing a disservice to individuals who are given the diagnosis of autism by considering the group as a whole, without further efforts to subtype based on something other than behavioral characteristics. (Contains references.)…
