Many preschoolers with autism spectrum disorders (ASD) present relative lack of receptive advantage over concurrent expressive language. Such profile emergence was investigated longitudinally in 54 infants at high-risk (HR) for ASD and 50 low-risk controls, with three language measures taken across four visits (around 7, 14, 24, 38 months). HR infants presented three outcome subgroups: ASD, other atypicality, and typical development. Reduced receptive vocabulary advantage was observed in HR infants by 14 months, but was maintained to 24 months only in ASD/other atypicality outcome subgroups while typically-developing HR infants regained a more normative profile. Few group differences appeared on a direct assessment of language and parent-reported functional communication. Processes of early development toward ASD outcome and in intermediate phenotypes are discussed.
