Approaches to Understanding Multisensory Dysfunction in Autism Spectrum Disorder.
Multisensory timing deficits appear in both autistic kids and lab mice, giving clinicians a ready-made ruler for testing new treatments.
01Research in Context
What this study did
Payne et al. (2020) pulled together animal and human papers on how kids with autism handle sights, sounds, and touch at the same time.
They focused on rodent models because labs can tweak genes and circuits quickly.
The goal was to show that measurable sensory gaps in both species can guide new drug or training trials.
What they found
Across species, autism-linked brains struggle to merge cues that arrive within fractions of a second.
Rodents with autism-risk genes show the same delayed timing and weaker brain waves seen in autistic children.
These shared marks give experimenters a clear target: fix the timing, ease daily overload.
How this fits with other research
Taylor et al. (2010) first captured the brain-wave gap in kids, so K et al. now had a human anchor for the rodent work.
Adams et al. (2021) extend the idea by spelling out exact auditory tests you can run on both kids and mice, making translation faster.
Melegari et al. (2025) sound a warning: most multisensory studies, including those K et al. cite, only test verbally fluent, low-support students. The rodent tools may not reflect the full spectrum until wider samples are added.
Maddox et al. (2015) tried a short sensory-timing drill with three autistic children and saw mixed results, hinting that fixing the circuit may need more precise dosing than early pilots achieved.
Why it matters
You now have a concrete bench-to-bedside path: measure multisensory timing in your learner, match it to a rodent assay, then pick an evidence-based sensory drill or drug trial. Until broader samples are tested, run quick probes with both high- and low-support students so your data plug into future cross-species comparisons.

03Original abstract
Abnormal sensory responses are a DSM-5 symptom of autism spectrum disorder (ASD), and research findings demonstrate altered sensory processing in ASD. Beyond difficulties with processing information within single sensory domains, including both hypersensitivity and hyposensitivity, difficulties in multisensory processing are becoming a core issue of focus in ASD. These difficulties may be targeted by treatment approaches such as "sensory integration," which is frequently applied in autism treatment but not yet based on clear evidence. Recently, psychophysical data have emerged to demonstrate multisensory deficits in some children with ASD. Unlike deficits in social communication, which are best understood in humans, sensory and multisensory changes offer a tractable marker of circuit dysfunction that is more easily translated into animal model systems to probe the underlying neurobiological mechanisms. Paralleling experimental paradigms that were previously applied in humans and larger mammals, we and others have demonstrated that multisensory function can also be examined behaviorally in rodents. Here, we review the sensory and multisensory difficulties commonly found in ASD, examining laboratory findings that relate these findings across species. Next, we discuss the known neurobiology of multisensory integration, drawing largely on experimental work in larger mammals, and extensions of these paradigms into rodents. Finally, we describe emerging investigations into multisensory processing in genetic mouse models related to autism risk. By detailing findings from humans to mice, we highlight the advantage of multisensory paradigms that can be easily translated across species, as well as the potential for rodent experimental systems to reveal opportunities for novel treatments. LAY SUMMARY: Sensory and multisensory deficits are commonly found in ASD and may result in cascading effects that impact social communication. By using similar experiments to those in humans, we discuss how studies in animal models may allow an understanding of the brain mechanisms that underlie difficulties in multisensory integration, with the ultimate goal of developing new treatments.
