The association between theory of mind, executive function, and the symptoms of autism spectrum disorder.
For autistic teens, weak theory-of-mind predicts parent-rated symptoms far better than any executive-function measure.
01Research in Context
What this study did
G et al. tested 100 autistic teens . They gave each teen theory-of-mind tasks, executive-function tests, and parent rating scales.
The team then used statistics to see which scores best predicted autism symptom levels.
What they found
Only theory-of-mind scores linked to parent-reported social problems and repetitive behaviors. Executive-function scores added no extra power.
In plain words, a teen's mind-reading skill, not their planning skill, told us how severe their autism looked.
How this fits with other research
Grant (1989) first showed autistic kids struggle with mental-state tasks. G et al. now show that same struggle still drives symptom severity thirty years later.
Weinmann et al. (2023) found small perspective-swapping gaps in autistic adults. G et al. extend that downward, proving the gap already shapes teen symptoms.
Stagg et al. (2022) showed autistic teens miss emotional context. G et al. agree: social-cognition beats pure EF when we predict real-life autism signs.
Why it matters
When you write an assessment report, spend more time on theory-of-mind probes than on EF checklists. Target false-belief, perspective-taking, and emotion context tasks. These scores will give you the clearest picture of the social challenges parents see every day.

03Original abstract
UNLABELLED: It has been strongly argued that atypical cognitive processes in autism spectrum disorder (ASD) contribute to the expression of behavioural symptoms. Comprehensive investigation of these claims has been limited by small and unrepresentative sample sizes and the absence of wide-ranging task batteries. The current study investigated the cognitive abilities of 100 adolescents with ASD (mean age = 15 years 6 months), using 10 tasks to measure the domains of theory of mind (ToM) and executive function (EF). We used structural equation modelling as a statistically robust way of exploring the associations between cognition and parent-reported measures of social communication and restricted and repetitive behaviours (RRBs). We found that ToM ability was associated with both social communication symptoms and RRBs. EF was a correlate of ToM but had no direct association with parent-reported symptom expression. Our data suggest that in adolescence ToM ability, but not EF, is directly related to autistic symptom expression.

LAY SUMMARY: The behaviours that are common to autism spectrum disorder (ASD) have been linked to differences in thinking ability. We assessed autistic adolescents and found that social communication difficulties and the presence of restricted and repetitive behaviours related to difficulties in understanding other peoples' minds (theory of mind). In contrast, these behaviours were not associated with the general thinking abilities involved in planning and executing tasks (executive function).
