Evidence for diminished multisensory integration in autism spectrum disorders . Individuals with autism spectrum disorders ( ASD ) exhibit alterations in sensory processing , including changes in the integration of information across the different sensory modalities . In the current study , we used the sound-induced flash illusion to assess multisensory integration in children with ASD and typically-developing ( TD ) controls . Thirty-one children with ASD and 31 age and IQ matched TD children ( average age = 12 years ) were presented with simple visual ( i.e. , flash ) and auditory ( i.e. , beep ) stimuli of varying number . In illusory conditions , a single flash was presented with 2-4 beeps . In TD children , these conditions generally result in the perception of multiple flashes , implying a perceptual fusion across vision and audition . In the present study , children with ASD were significantly less likely to perceive the illusion relative to TD controls , suggesting that multisensory integration and cross-modal binding may be weaker in some children with ASD . These results are discussed in the context of previous findings for multisensory integration in ASD and future directions for research .
