Multisensory temporal integration in autism spectrum disorders . The new DSM-5 diagnostic criteria for autism spectrum disorders ( ASDs ) include sensory disturbances in addition to the well-established language , communication , and social deficits . One sensory disturbance seen in ASD is an impaired ability to integrate multisensory information into a unified percept . This may arise from an underlying impairment in which individuals with ASD have difficulty perceiving the temporal relationship between cross-modal inputs , an important cue for multisensory integration . Such impairments in multisensory processing may cascade into higher-level deficits , impairing day-to-day functioning on tasks , such as speech perception . To investigate multisensory temporal processing deficits in ASD and their links to speech processing , the current study mapped performance on a number of multisensory temporal tasks ( with both simple and complex stimuli ) onto the ability of individuals with ASD to perceptually bind audiovisual speech signals . High-functioning children with ASD were compared with a group of typically developing children . Performance on the multisensory temporal tasks varied with stimulus complexity for both groups ; less precise temporal processing was observed with increasing stimulus complexity . Notably , individuals with ASD showed a speech-specific deficit in multisensory temporal processing . Most importantly , the strength of perceptual binding of audiovisual speech observed in individuals with ASD was strongly related to their low-level multisensory temporal processing abilities . Collectively , the results represent the first to illustrate links between multisensory temporal function and speech processing in ASD , strongly suggesting that deficits in low-level sensory processing may cascade into higher-order domains , such as language and communication .
