Sensory Processing and Autistic Traits: Mediation Effect of Frontal Alpha Asymmetry.
Deukgeun Yoon, Eun Young Kim
PMID 36721758WHAT IT FOUND
In 73 neurotypical adults, sensation avoiding predicted autistic traits directly and indirectly through relative right-sided cortical activity.
This brain pattern partially mediated the link, suggesting withdrawal motivation may underpin how sensory avoidance relates to autistic features.
Key findings
01Sensation avoiding patterns were significantly correlated with both frontal alpha asymmetry (FAA) and autistic traits.
02FAA partially mediated the relationship between sensation avoiding patterns and autistic traits.
03Higher sensation avoiding was related to increased autistic traits directly and indirectly through relative right-sided cortical activity.

What it does not show
The study included only neurotypical adults, so findings may not apply to individuals diagnosed with ASD. Results cannot be generalized to children because sensory processing changes with age. Sensory processing was measured using self-report questionnaires, which are subjective. The study did not collect data on participants' medication use, though the authors note FAA is typically unaffected by medication.
Declared interests
The authors declare no conflicts of interest.
The easy way to misread this
Do not interpret the mediation effect as evidence that sensory interventions change autistic traits. The study is cross-sectional and did not test any intervention, so it cannot establish causality or treatment efficacy.
