Executive Function and Social Cognition Performance Predicts Social Difficulty for Autistic Adults.

PMID 40747689WHAT IT FOUND
Executive function and social cognition both predict social difficulty in autistic adults, but independently.
Neither mediates the other, so assessing and targeting these two domains separately is more useful than assuming they are linked.
Key findings
01Executive function and social cognition predict social responsiveness through separate pathways, with no significant indirect effect in any mediation model.
02Better performance-based executive function (cognitive flexibility) predicted lower clinician-observed social difficulty, while higher self-reported executive dysfunction predicted higher self-reported social difficulty.
03IQ was the strongest predictor of social cognition performance, explaining more variance than executive function measures.

What it does not show
The study is cross-sectional, so it cannot determine causality or directionality between variables. Participants with intellectual disability (IQ < 70) were excluded, and the sample had a high mean IQ (110), so findings may not generalize to the full autism spectrum. There was no neurotypical control group, so it is unclear how these relationships compare to non-autistic adults. Self-reported measures (BRIEF-A, SRS-2) may be influenced by reporter bias, such as mood or self-awareness, rather than actual functional ability. The study was exploratory, with many models tested, increasing the risk of false-positive findings.
Declared interests
The authors declare no conflicts of interest. The work was funded by the Australian Research Council and the National Health and Medical Research Council.
The easy way to misread this
Do not assume that improving executive function will automatically improve social cognition or social communication skills. The study found no mediation effect, meaning these domains predict social difficulty independently. Targeting one does not guarantee improvement in the other.
