Hypothesis
How does the cortical basis of social processing change throughout development in children aged 3 to 12 years?
Conclusion
The study found that children as young as 3 years old show significant neural responses to social interactions, indicating early development of social interaction perception.
Supporting Evidence
- Children as young as 3 years old show significant neural responses to social interactions.
- Social interaction responses in the STS appear adult-like by age 7.
- Visual and social features can predict brain activity in children across the cortex.
Takeaway
This study shows that even little kids can understand social interactions, and their brains respond to these interactions just like adults do.
Methodology
The study used fMRI data to analyze brain activity in children and adults while they watched a labeled animated movie, employing a voxel-wise encoding model.
Limitations
The study did not have functional localizer data for subjects and used a larger anatomical ROI mask for the STS, which may limit the ability to detect finer developmental differences.
Participant Demographics
Participants included 122 children aged 3-12 years (64 females) and 33 adults (20 females).
