NVIQ entered in Step 1; WM Composite entered in Step 2. ^a Language measured using the Clinical Evaluation of Language Fundamentals, 4th Edition, Core Language (scaled score; [26]). ^b Symptom severity measured using: Social Responsiveness Scale [27] and Autism Diagnostic Observation Schedule (ADOS) Communication + Social Total Score [28].
