Note: ASD = autism spectrum disorder; TLA = typically developing, language age-matched; TCA = typically developing, chronological age-matched. PLS-4 = Preschool Language Scale-4th Edition; MSEL = Mullen Scales of Early Learning; VABS = Vineland Adaptive Behavior Scales. In each row, groups with different superscripts differ significantly from one another, p <.05; e.g., for chronological age, (ASD = TCA) > TLA.
