Do kids' social skills develop alongside their physical skills?
A child's ability to understand others' minds is independent of their physical motor skills and mirror neuron-related abilities like imitation.

The Relationship between Social and Motor Cognition in Primary School Age-Children
What they did
Researchers evaluated 101 children aged between 4 and 12 years-old on a series of tasks measuring theory of mind, motor skills, imitation, and action understanding. To test their physical and social cognitive abilities, children completed tasks such as planning how to grip a bar, predicting the intent of photographed hand gestures, and solving classic false-belief puzzles. The researchers then analyzed whether performance in these physical domains correlated with social cognitive performance while controlling for age and non-verbal IQ.
What they found
Theory of mind performance was strongly predicted by age and non-verbal intelligence but had no relationship with motor skills or mirroring abilities. Conversely, imitation and action-understanding tasks were closely related to each other and showed weak connections to basic motor planning and sequencing. These results indicate that social mentalizing and motor systems develop relatively independently rather than originating from a single, unified action system.
The limits
What it doesn't show
Because the study was cross-sectional rather than longitudinal, it cannot determine whether early motor achievements influence social development over longer periods. Additionally, some theory of mind tasks suffered from ceiling effects, meaning they might not have fully captured the true variation in older children's social abilities. Finally, since the sample did not include children with formal diagnoses of autism or developmental coordination disorder, the findings may not apply directly to clinical populations where these skills often co-occur.
Key terms
- theory of mind
- The cognitive ability to attribute mental states, such as beliefs, desires, and intentions, to oneself and others.
- mirror neuron system
- A brain network that activates both when an individual performs an action and when they observe someone else performing that same action.
- motor planning
- The cognitive process of organizing and preparing physical movements before executing them.
- cross-sectional design
- A research method that compares different groups of participants at a single point in time to examine developmental changes.
- non-verbal IQ
- A measure of fluid intelligence and problem-solving abilities that does not rely on language skills.
- mentalizing
- The active cognitive process of thinking about and interpreting the thoughts, feelings, and beliefs of others.

Common questions
Why did the researchers oversample children with extreme scores on the parent questionnaires?
By deliberately selecting children with very high or very low scores on parent reports, the researchers increased the variance in abilities within their sample, which gave them more statistical power to detect potential links between different cognitive skills.
Does this study prove that mirror neurons have nothing to do with social interaction?
No, it only shows that mirroring abilities (like imitation and gesture recognition) do not directly relate to abstract theory of mind tasks in school-age children, meaning these skills likely rely on different cognitive pathways.
Why are motor and social deficits often seen together in disorders like autism if these domains are independent?
Although the systems develop independently in typical children, developmental disorders might stem from shared genetic or neurological vulnerabilities that broadly affect multiple brain systems at once.
What is the difference between imitation and emulation in this context?
Imitation involves copying the precise physical movements of an action, whereas emulation focuses only on reproducing the final goal or outcome of the action.
