Note.

Group difference at p < .05. Bayley raw and composite scores were measured by the Bayley Scales of Infant Development. Number of words understood was measured by the Communicative Development Inventory (Words & Gestures form). Autism severity was measured by the Autism Diagnostic Observation Schedule-2 (ADOS-2) standardized calibrated severity scores.
