Abstract:
This longitudinal study examined early predictors of language development in 74 young children with Autism Spectrum Disorder (ASD) in Taiwan. Participants were assessed twice (initial age between 17 and 35 months) on responding to joint attention (RJA), initiating joint attention (IJA), motor imitation with objects (object imitation; OI) and without objects (manual imitation; MI), and receptive and expressive language. The two assessments were 18 months apart. Results showed that both RJA and MI concurrently and longitudinally predicted receptive and expressive language across the two assessments. These findings were not entirely consistent with the limited and mixed findings of Western longitudinal studies. However, they have implications for early interventions aiming to facilitate language development in children with ASD internationally.
