We explored whether attentional control in ASD varies as a function of motor proficiency. Nineteen children with ASD and 26 typically-developing controls completed the Movement Assessment Battery for Children and two ocular motor tasks requiring them to generate a saccade toward, and fixate, a visual target in the presence or absence of a distractor. The ASD group demonstrated poorer accuracy than typically-developing controls when distractors were present. Importantly, however, ASD symptomology was only related to poorer accuracy in individuals with motor difficulties. These findings suggest that distractor inhibition may be selectively impaired in this subgroup.

Superior Visual Search and Crowding Abilities Are Not Characteristic of All Individuals on the Autism Spectrum / E. LINDOR in Journal of Autism and Developmental Disorders, 48-10 (October 2018)

We examined whether performance on these tasks changed as a function of motor proficiency in children with varying levels of ASD symptomology. Children with high ASD symptomology outperformed all others on complex visual search tasks, but only if their motor skills were rated at, or above, age expectations. For the visual crowding task, children with high ASD symptomology and superior motor skills exhibited enhanced target discrimination, whereas those with high ASD symptomology but poor motor skills experienced deficits. These findings may resolve some of the discrepancies in the literature.
