Impairments to visual disengagement in autism spectrum disorder: a review of experimental studies from infancy to adulthood.

ABSTRACT

Impairments in visual disengagement are a current focus of research in autism spectrum disorders (ASD) and may play a key role in the early expression of social-emotional deficits associated with the disorder. This review summarizes current knowledge of visual disengagement and orienting in ASD. Convergent reports from infancy to adulthood indicate that (1) impairments to visual disengagement are apparent on Gap-Overlap tasks, spatial orienting tasks, and tasks involving social stimuli; and (2) these impairments emerge in the first year of life and continue into adulthood. The relationships between visual disengagement, orienting, joint attention, emotional regulation, and IQ are discussed in relation to ASD.
