Early factors of decontextualized language use in 2-year-olds and associations with ASD

This is a registration of an analysis plan within the longitudinal study Early Autism Seden (EASE; www.projektsmasyskon.se). The plan is registered after data collection, but prior to processing and analysis of the data. We aim to study how early factors of formal language (receptive vocabulary and sentence understanding) and social communication abilities (early gesture use, play, object actions, pretend-play and imitation), are associated with decontextualized language use at 24 months of age. We also aim to investigate associations between decontextualized language use and ASD likelihood and traits.
