Perception of biological motion in autism spectrum disorders.

In individuals with autism or autism-spectrum-disorder (ASD), conflicting results have been reported regarding the processing of biological motion tasks. As biological motion perception and recognition might be related to impaired imitation, gross motor skills and autism specific psychopathology in individuals with ASD, we performed a functional MRI study on biological motion perception in a sample of 15 adolescent and young adult individuals with ASD and typically developing, age, sex and IQ matched controls. Neuronal activation during biological motion perception was compared between groups, and correlation patterns of imitation, gross motor and behavioral measures with neuronal activation were explored.

Quantitative assessment of neuromotor function in adolescents with high functioning autism and Asperger Syndrome.

Background: Motor impairment in children with Asperger Syndrome (AS) or High functioning autism (HFA) has been reported previously. This study presents results of a quantitative assessment of neuromotor skills in 14-22 year old HFA/AS.

Methods: 16 HFA/AS and 16 IQ-matched controls were assessed by the Zurich Neuromotor Assessment (ZNA).

Imitation and language abilities in adolescents with Autism Spectrum Disorder without language delay.

Introduction: Difficulties imitating gestures have been found in several studies in children and adolescents with Autism Spectrum Disorders (ASD). It has been hypothesized that imitation abilities might be precursors of language abilities in young children with autism. No study on imitation and language abilities in adolescents with ASD has been performed to date.
