Abstract

This study examined the extent to which a discrepant comprehension-production profile (i.e., relatively more delayed comprehension than production) is characteristic of the early language phenotype in autism spectrum disorders (ASD) and tracked the developmental progression of the profile. Our findings indicated that a discrepant comprehension-production profile distinguished toddlers (30 months) with ASD from late talkers without ASD (91% sensitivity, 100% specificity) in groups that were comparable on expressive language, age, and socioeconomic status. Longitudinal data for children with ASD revealed that the discrepant profile steadily decreased from 30 to 44 months until there was no significant comprehension-production difference at 66 months. In conclusion, results suggest that lower comprehension than production may be an age-specific marker of toddlers with ASD.
