Developmental correlates of different types of motor imitation in young children with autism spectrum disorders.

This study used a concurrent correlational design to examine associations between three types of motor imitation with objects and three proposed correlates in 32 two- and three-year-old children diagnosed with ASD. Attention-following and fine motor ability were significant, unique correlates of imitation in an observational learning context. Attention-following was a significant correlate of imitation in a direct elicitation context. Social reciprocity was a significant correlate of imitation in an interactive play context. These associations were observed after controlling for general developmental level. Results support previous findings that motor imitation may not reflect a unitary construct for children with ASD and that different skills may underlie the performance of different types of motor imitation. Implications for interventions targeting motor imitation are discussed.
