The following groups of participants will be eligible for the study:
Objective: The primary objective of the proposed studies is to utilize neuroimaging (functional Magnetic Resonance Imaging [fMRI], structural MRI [sMRI], Magnetoencephalography [MEG]) and neuropsychological tools (eye-tracking, cognitive experiments, clinical neuropsychological measures, questionnaires, etc.) to identify cognitive idiosyncrasies (e.g., social-cognitive deficits, visual perceptual assets, and savant skills) characteristic of individuals on the autism spectrum and their neural underpinnings across childhood and adulthood.
Study Population: Children, adolescents, and adults with autism spectrum disorders (ASDs), controls (i.e., typically developing children, adolescents, and adults and those with mild to moderate mental retardation), as well as caregivers/legal guardians/parents of these individuals.
Design: Descriptive/Characterization/Observational studies using primarily neuropsychological and neuroimaging methodologies.
Outcome Measures: Behavioral (reaction time, accuracy, eye movements, etc.) and neuroimaging (brain morphometry, BOLD, electrophysiology, etc.).

Subjects will include:
Inclusion criteria for cognitively impaired children without ASD, Subjects will include:
Subjects in the ASD group will:
All subjects, except for savants, also will be excluded if they have:
Exclusion criteria for cognitively impaired children:
Healthy volunteers, except for parents of individuals with autism spectrum disorders, parents of healthy volunteers, and parents of children with cognitive impairments, will also be excluded if they have:
1. a current or past history of axis I psychiatric conditions or any current usage of psychiatric medication.
Savants have less restrictive exclusionary criteria because: 1) they are a very rare group, thus we don t want to limit recruitment further and 2) we can examine common and unique cognitive mechanisms across savants, a question of keen interest, regardless of co-morbidities. Those with tumors or other neuroimaging-relevant contraindications will be excluded from fMRI/MEG procedures.
