Article Abstract:
Autistic children are able to imitate a series of hand-actions, but when required to inhibit these imitations and produce opposing hand-actions, they perform poorly as compared to the verbally-matched controls and the normal preschoolers. Autistic children also tend to show inabilities in strategically managing the delay period. While significant correlations exist for task performance for both clinical groups, no such correlation exists for the preschoolers. The significance of these results are discussed.

Article Abstract:
Cognitive factors associated with behavioral problems in 2 year olds from predominantly disadvantaged families were researched based on home visit ratings, detailed video-based coding of mother-child interactions and tests of theory of mind (ToM), executive function (EF) and verbal ability. Results showed that harsh parenting and deficits in ToM and verbal ability, each predicted unique variance in behavioral problems, while independent effects of EF were marginally significant.

Article Abstract:
Siblings of children with autism show a greater prevalence of executive dysfunction than controls. Furthermore, siblings of children with autism have superior spatial span and rote-recall and an unusual pattern of associations and dissociations between task performances. This research represents significant progress towards uncovering some of the cognitive characteristics of the autism wider phenotype. However, there are still many unanswered questions.
