Perception of audio-visual synchrony in infants at elevated likelihood of developing autism spectrum disorder.

Abstract

Findings suggest that early deficits in multisensory integration may impair language development among infants with elevated likelihood of developing ASD. •Perceptual integration of auditory and visual cues within speech is important for language development. •Prior work suggests that children with ASD are less sensitive to the temporal synchrony within audio-visual speech. •In this study, infants at elevated likelihood of developing ASD showed a larger temporal binding window for adynamic social event (Speaking Face) than TD infants, suggesting less efficient multisensory integration.
