Background: Social inattention is common in children with autism whereas associative learning capabilities are considered a relative strength. Identifying early precursors of impairment associated with autism could lead to earlier identification of this disorder. The present study compared social and non-social visual attention patterns as well as associative learning in infant siblings of children with autism (AU sibs) and low-risk (LR) infants at 6 months of age.
Methods: Twenty-five AU sibs and 25 LR infants were observed in a novel social-object learning task, within which attention to social and non-social cues was contrasted. Video recorded data were coded for percent duration of gaze to objects or caregiver. Movement rates to activate the toy within the associative learning task were also quantified.
Results: Both groups learned the association between moving a switch and activating a cause–effect toy. AU sibs spent less time looking at caregivers and more time looking at the toy or joystick when their caregivers made no attempts to engage their attention. However, response to caregiver-initiated social bids was comparable for both groups.
Conclusions: Infrequent self-initiated socially directed gaze may be an early marker of later social and communication delays.
