The pattern of sensory processing abnormalities in autism.
Autism brings broad sensory issues that can shrink with age except for light-touch bother, but newer lab tests say adult touch detection looks normal.
01Research in Context
What this study did
Schneider et al. (2006) compared kids and adults with autism to matched peers. They used the Sensory Profile to check hearing, vision, touch, and taste. The team wanted to see if sensory issues fade with age.
What they found
People with autism scored much lower on almost every sense. Some scores got better as they got older, but light-touch problems stayed just as bad. The authors say low-threshold touch does not improve with age.
How this fits with other research
Klintwall et al. (2011) asked parents of toddlers the same questions and found the same pattern. Crane et al. (2009) later showed 94% of autistic adults still hit extreme scores, so the issue lasts.
Hense et al. (2019) ran a different touch test on adults and saw no problems at all. This looks like a clash, but the 2006 paper used parent checklists while the 2019 team used a lab task. Checklists catch everyday bother; lab tasks measure tiny detection limits.
Sapey-Triomphe et al. (2023) add another twist. Autistic adults say they are very sensitive, yet their brain waves look normal. Again, self-report and lab scores do not line up. Together these studies say: touch sensitivity is real, but how you ask changes what you find.
Why it matters
If you treat a child who hates light touch, do not assume they will outgrow it. Keep giving tag-free shirts, seamless socks, or deep-pressure options even in the teen years. Also, use more than one tool to check sensory issues. A quick parent survey can flag trouble, but a lab test may show typical thresholds. Pair both before you write goals or pick equipment.

03Original abstract
The study was undertaken to evaluate the nature of sensory dysfunction in persons with autism. The cross-sectional study examined auditory, visual, oral, and touch sensory processing, as measured by the Sensory Profile, in 104 persons with a diagnosis of autism, 3-56 years of age, gender-and age-matched to community controls. Persons with autism had abnormal auditory, visual, touch, and oral sensory processing that was significantly different from controls. This finding was also apparent when the high and low thresholds of these modalities were examined separately. At later ages for the group with autism, lower levels of abnormal sensory processing were found, except for low threshold touch, which did not improve significantly. There was a significant interaction in low threshold auditory and low threshold visual, suggesting that the two groups change differently over time on these variables. These results suggest that sensory abnormalities in autism are global in nature (involving several modalities) but have the potential to improve with age.
