Touch Processing and Social Behavior in ASD.
Check for over- or under-reactivity to touch during social assessments—it may drive social difficulties more than autism severity alone.
01Research in Context
What this study did
O Miguel et al. (2017) looked at how kids with autism react to touch. They asked if over- or under-sensitive skin predicts social trouble.
The team tested school-age youth and tracked touch style and social problems.
What they found
Kids who hated light touch or craved deep squeeze had more social issues. Touch seeking alone did not predict trouble.
Touch reactivity mattered more than autism severity for social life.
How this fits with other research
Gunderson et al. (2021) show the story starts earlier. High-risk toddlers already show touch and sound issues at 12 months, before diagnosis.
O'Riordan et al. (2006) seems to disagree. They found autistic kids feel fine on lab touch tests. The gap is real-life versus lab. Helga used daily-life reports; Michelle used tiny vibration machines.
Mello et al. (2025) carry the link into adults. Autistic adults avoid touch and rate hugs as less nice, especially men.
Why it matters
Add two quick touch questions to your intake. Ask, "Does the child pull away from tags or seek bear hugs?" Note the answer. If touch is off, teach peers to offer side hugs or deep-pressure high-fives first. Social drills sink in faster when the skin is calm.

03Original abstract
Abnormal patterns of touch processing have been linked to core symptoms in ASD. This study examined the relation between tactile processing patterns and social problems in 44 children and adolescents with ASD, aged 6-14 (M = 8.39 ± 2.35). Multiple linear regression indicated significant associations between touch processing and social problems. No such relationships were found for social problems and autism severity. Within touch processing, patterns of hyper-responsiveness and hypo-responsiveness best predicted social problems, whereas sensory-seeking did not. These results support that atypical touch processing in individuals with ASD might be contributing to the social problems they present. Moreover, it the need to explore more in depth the contribution of sensory features to the ASD phenotype.
