Abstract: | Autism spectrum disorders (ASD) form a continuum of neurodevelopmental disorders, characterized by deficits in communication
and reciprocal social interaction, as well as by repetitive behaviors and restricted interests. Sensory disturbances are also
frequently reported in clinical and autobiographical accounts. However, surprisingly few empirical studies have characterized
the fundamental features of sensory and multisensory processing in ASD. The current study is structured to test for potential
differences in multisensory temporal function in ASD by making use of a temporally dependent, low-level multisensory illusion.
In this illusion, the presentation of a single flash of light accompanied by multiple sounds often results in the illusory
perception of multiple flashes. By systematically varying the temporal structure of the audiovisual stimuli, a “temporal window”
within which these stimuli are likely to be bound into a single perceptual entity can be defined. The results of this study
revealed that children with ASD report the flash-beep illusion over an extended range of stimulus onset asynchronies relative
to children with typical development, suggesting that children with ASD have altered multisensory temporal function. These
findings provide valuable new insights into our understanding of sensory processing in ASD and may hold promise for the development
of more sensitive diagnostic measures and improved remediation strategies. |
