A systematic review and meta-regression analysis of social functioning correlates in autism and typical development.
Classic cognitive scores give only small clues about social life in autism, so test behavior where it happens.
01Research in Context
What this study did
Gillespie-Lynch et al. (2019) pooled 133 studies that measured social skills and well-known cognitive skills in autistic and typical children.
They looked at theory of mind, joint attention, and executive function.
A computer model checked how strongly each skill lined up with real-life social success.
What they found
All three skills touched social ability, but the links were small to medium.
The ties were a little stronger in autistic samples than in typical kids.
In plain words, scoring high on theory-of-mind tests explains only a sliver of why a child does well on the playground.
How this fits with other research
Wang et al. (2013) found large gains after social-skills training, yet Kristen shows the baseline skills we usually target are weak predictors.
Pellicano (2013) followed preschoolers for three years and saw early executive function predict later social problems, giving EF more weight than Kristen’s broad average does.
Heald et al. (2020) also link parent-rated EF to everyday communication, again hinting EF may matter more than Kristen’s overall small effect suggests.
The papers do not truly clash: Kristen averages many ages and measures, while Elizabeth and M zoom in on school-age EF and real-world parent reports.
Why it matters
Stop assuming a child who fails a false-belief task will automatically struggle socially.
Use brief EF checklists and real-life social probes instead of long theory-of-mind batteries.
When you pick an intervention, target behavior in context; cognitive scores won’t tell you the whole story.

03Original abstract
Differences in social functioning are a hallmark feature of autism spectrum disorder (ASD), and much research has been devoted to locating cognitive and developmental explanations for this domain. To sort through this literature, we conducted a systematic review and meta-analysis that quantifies the extent to which several of these candidate constructs are associated with social functioning. We gathered 881 effect sizes calculated from 133 unique participant samples, and synthesized Pearson's r correlations between social functioning and three cognitive constructs; (a) theory of mind (ToM), (b) executive function, and (c) central coherence, and five developmental constructs: (d) initiating joint attention, (e) responding to joint attention, (f) imitation, (g) pretend play, and (h) visual fixation to social stimuli. We synthesized effect sizes using robust variance estimation for each putative correlate, for populations with ASD and typical development (TD) separately. We also conducted a series of meta-regressions to determine if sample and study features moderated effect sizes. We found that, in the ASD group, effect size estimates were significant and small (<0.30) for ToM, executive function, and initiating joint attention. Effect size estimates were significant and moderate (0.30 < r < 0.50) for imitation and response to joint attention. In the TD group, effect size estimates for ToM, executive function, and initiating joint attention were significant and small. In a meta-regression collapsed across correlates, we found that effect sizes were significantly larger in the ASD group (P < 0.05) and decreased as mental age increased (P < 0.001).

LAY SUMMARY: In this meta-analysis, we found that correlations between social functioning and several constructs used to explain the developmental or cognitive origins of social functioning were quite low. This could mean that researchers will need to develop new theories about social functioning in ASD.
