Hypothesis
How does the medial prefrontal cortex function during executive tasks in individuals with autism spectrum disorders?
Conclusion
The study found that individuals with autism showed atypical activation patterns in the medial prefrontal cortex during executive function tasks.
Supporting Evidence
- The ASD group showed greater activation in medial prefrontal cortex during the alphabet task compared to controls.
- Both groups performed similarly on behavioral tasks, indicating no significant differences in performance.
- Task-specific differences in brain activation were observed, suggesting variability in executive function processing.
Takeaway
This study looked at how people with autism think and make decisions. It found that their brains work a bit differently when doing certain tasks.
Methodology
Participants with autism and a control group performed two executive function tasks while undergoing fMRI scanning.
Potential Biases
Potential biases in matching participants and the small sample size may affect the generalizability of the findings.
Limitations
The study focused only on high-functioning individuals with autism, which may not represent the entire spectrum.
Participant Demographics
15 participants with autism (12 males, 3 females) and 18 control participants (13 males, 5 females), matched for age and IQ.
