Additional Study Information: The NVLD study investigates neural circuits that support cognitive control and learning processes in children with NonVerbal Learning Disability (NVLD). Children come with a parent to spend the day at CUMC. They complete tests of their memory and thinking and an MRI scan, which is a safe and painless method of taking pictures of the brain. Parents are asked to fill out surveys and answer questions. Visits take place on Saturdays or on school holidays, and generally take 6 hours.
