Parameters of semantic multisensory integration depend on timing and modality order among people on the autism spectrum: Evidence from event-related potentials

► Studied effects of timing and modality order for autistics (ASD) and typical peers. ► Measured behavior and electrophysiology of semantic multisensory integration. ► No differences were noted in reaction time or accuracy between the groups. ► ERPs showed increased reliance on perception for ASD but not TD peers. ► Timing asymmetries were consistent with perceptual strengths in ASD.
