Marjorie Solomon, Ph.D., of the University of California, Davis, observes that while learning is atypical in persons with autism spectrum disorders (ASDs), it is possible under the right conditions. She posits that systems-level computational models of the cognitive and neural mechanisms underlying learning can provide a useful framework for developing a more precise and mechanistic understanding of learning in ASDs. Given consistent findings of deficits in executive functions related to reduced functional connectivity between frontal and striatal brain regions, she hypothesizes this result may reflect altered PFC functioning or connectivity. This study will use event-related fMRI, and functional connectivity analysis to clarify these learning findings and to explore the relationship between basal ganglia function and restricted and restricted and repetitive behaviors.
