Executive functions and the natural habitat behaviors of children with autism.
Full Abstract
Research suggests that impairments in executive functions play a role in the cognitive deficit in autism. Possible autism-specific impairments include an inability to engage in goal-directed behaviors and adjust behaviors given environmental demands. What has been described as executive functions is based largely on observations of performance in the laboratory rather than in natural settings. An ecological method first described by Barker and Wright and adapted by Scott was used to assess the patterns of goal-directed behaviors of eight children with autism and eight chronological and mental age comparable children with Down syndrome. Quantitative and qualitative features of naturalistic behaviors were collected, and coded using previously described categories of children's behavior. Results indicated that children with autism exhibited shorter and less overlapping goal-directed behaviors. These data suggest a cognitive difference rather than developmental delay, and lend support for impaired executive functions in autism. Practical implications for educators and caregivers are discussed.
