This is a mentored Research Scientist Career Development Award for research and training support. High-density electroencephalography (EEG) methods will be used to study brain substrates of cognitive problems in autism. The research focuses on investigating the brain basis for impairments in behavioral inhibition and self-monitoring, which are related to difficulty inhibiting inappropriate behaviors in social situations or repetitive behaviors. The project will also examine relationships between EEG measures of inhibitory control and error monitoring, clinical symptoms of autism, and gaze patterns with complex social stimuli, in order to gain a better understanding of how neurocognitive impairments contribute to symptom development and phenotypic variability in the population. Establishing brain basis of cognitive problems will help lay a foundation for future treatment studies, which can lead to improved life of affected individuals.
