Brief report: parental child-directed speech as a predictor of receptive language in children with autism symptomatology.

Facilitative linguistic input directly connected to children's interest and focus of attention has become a recommended component of interventions for young children with autism spectrum disorder (ASD). This longitudinal correlational study used two assessment time points and examined the association between parental undemanding topic-continuing talk related to the child's attentional focus (i.e., follow-in comments) and later receptive language for 37 parent-child dyads with their young (mean = 21 months, range 15-24 months) children with autism symptomology. The frequency of parental follow-in comments positively predicted later receptive language after considering children's joint attention skills and previous receptive language abilities.
