Associations between early language, motor abilities, and later autism traits in infants with typical and elevated likelihood of autism.

ABSTRACT: Slower acquisition of language and motor milestones are common in infants with later autism and studies have indicated that motor skills predict the rate of language development, suggesting these domains of development may be interlinked. However, the inter-relationships between the two domains over development and emerging autistic traits are not fully established. We studied language and motor development using standardized observational and parent-report measures in infants with (n = 271) and without (n = 137) a family history of autism across four waves of data collection from 10 to 36 months. We used Random Intercept Cross-Lagged Panel Models to examine contemporaneous and longitudinal associations between language and motor developments in both elevated and typical likelihood groups.
