and the development of executive dysfunction in autism spectrum disorders.

An existing computational model of the prefrontal cortex and its role in executive control is shown to explain this dichotomous pattern of behavior by positing abnormalities in the dopamine-based modulation of frontal systems in individuals with autism.

Neurodevelopment and executive function in autism

Evidence from studies probing response inhibition and working memory indicate impairments in these core components of executive function, as well as compensatory mechanisms that permit normative function in autism.

Executive Functions in Children with Autism : An Overview

Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent difficulties in social communication and interaction and restrictive, repetitive, and stereotyped patterns

A Review of Language, Executive Function, and Intervention in Autism Spectrum Disorder.

It is found that interventions that target pragmatic ability have been found to improve executive function skills, and conversely, executive function interventions are linked with improvements in social skills in children with ASD.

Executive Function in Fragile X Syndrome: A Systematic Review

A systematic review of behavioral studies using performance-based measures is needed to provide a summary of EF deficits across domains in males and females with FXS, discuss clinical and biological correlates of these EF deficits, identify critical limitations in available research, and offer suggestions for future studies in this area.

Cognitive flexibility in adults with high functioning autism

No deficit was found in presetting, response inhibition, set shifting, and a priori planning in participants with autism, even when the medication factor was taken into account, and individuals with HFA were slow in reacting.

Neuropsychological profile of executive functions in autism spectrum disorder and schizophrenia spectrum disorders: a comparative group study in adults

As assessed by numerous neuropsychological tasks, individuals with autism spectrum disorder (ASD) and schizophrenia spectrum disorders (SSDs) have similar impairments related to executive functions

Executive Functions in Young Adults With Autism Spectrum Disorder

Researchers have proposed that autism spectrum disorder (ASD) is characterized, at least in part, by executive function (EF) difficulties associated with the integrity of the frontal lobe. Given the

Working memory deficits in high-functioning adolescents with autism spectrum disorders: neuropsychological and neuroimaging correlates

It is concluded that within the working memory system specific problems of spatial working memory are often seen in adolescents with ASD, and neuroimaging studies indicate a more global working memory processing or connectivity deficiency, rather than a focused deficit in the prefrontal cortex.

Executive function abilities in autism and Tourette syndrome: an information processing approach.

This study used information processing paradigms to provide a detailed examination of executive function abilities in autism and suggests a new conceptual framework and general method for investigating the cognitive underpinnings of neurodevelopmental disorders.

Autism as an executive disorder

This chapter discusses the neurobiological and neurophysical dimensions of autism and how executive disorders can bring about an inadequate "theory of mind" in autism.

Two Intact Executive Capacities in Children with Autism: Implications for the Core Executive Dysfunctions in the Disorder

Results are consistent, at least, with the hypothesis that children with autism are challenged by executive tasks because they are unlikely to encode rules in a verbal form.

Executive functions and developmental psychopathology.

It is revealed that EF deficits are consistently found in both ADHD and autism but not in CD (without ADHD) or in TS, and both the severity and profile of EF deficits appears to differ across ADHD and Autism.

A longitudinal study of executive function and theory of mind development in autism

Abstract Both executive function and theory of mind impairment have been suggested as primary deficits of autism. One test of the primacy of a deficit is its persistence and stability throughout

Intact and impaired memory functions in autism.

The group with autism performed significantly worse than comparison subjects on measures of temporal order memory, source memory, supraspan free recall, working memory, and EF, but not on short- and long-term recognition, cued recall, or new learning ability, consistent with the predictions of the EF theory.

Inhibitory Function in Nonretarded Children with Autism

It is suggested that at least two components of inhibition are spared in individuals with autism, standing in contrast to flexibility and other executive deficits that have been found in previous studies.

Cerebral correlates of preserved cognitive skills in

Functional MRI of subjects during the performance of the EFT was employed to test the hypothesis that normal subjects and a group with autism would activate different brain regions and that differences in the patterns of these regional activations would support distinct models of cerebral processing underlying EFT performance in the two groups.
