Everything has Its Time: Narrow Temporal Windows are Associated with High Levels of Autistic Traits Via Weaknesses in Multisensory Integration

The present study examined whether fundamental sensory functions such as temporal processing and multisensory integration are related to autistic traits in the general population. Both a narrower temporal window (TW) for simultaneous perception, as measured by a temporal order judgement task, and a reduced ability to engage in multisensory integration during the sound-induced flash illusion task were related to higher levels of autistic traits. Additionally, a narrow TW is associated with high levels of autistic traits due to a deficiency in multisensory integration. Taken together, these findings suggest that alterations in fundamental functions produce a cascading effect on higher-order social and cognitive functions, such as those experienced by people with autism spectrum disorder.
