Is developmental imitation related to rational imitation in young children with ASD?

Researchers studied how different types of copying behaviors relate to each other in young autistic children. They found that when autistic children naturally copy others during play, they're also better at copying actions that make sense for achieving goals. However, being able to copy when directly asked didn't predict this logical copying ability. This suggests different copying skills may develop independently in autism.

This correlational study examined relationships between different types of imitation in 40 young children with autism (23-48 months) and 42 typically developing children (12-24 months). Researchers measured instructed imitation, spontaneous imitation, and rational imitation using established paradigms including the head-touch task and hidden box experiment. The study introduced IMETCHASD as a new tool for measuring imitation in interactive play contexts. Results revealed that spontaneous imitation was significantly associated with rational imitation in children with autism, even after controlling for cognitive abilities.

However, no significant correlations were found between instructed imitation and rational imitation in either group.

Findings suggest spontaneous imitation skills may be more predictive of rational imitation abilities than instructed imitation in autism. This could inform assessment approaches and intervention targeting, emphasizing naturalistic play-based imitation rather than structured copying tasks.

Small sample size (n=40 for ASD group), correlational design prevents causal inferences, age ranges differ between groups which may confound comparisons, and the study only examines associations rather than intervention effects.

This study used a correlational design to examine associations between instructed imitation, spontaneous imitation, and rational imitation in children with autism spectrum disorder (ASD) between 23-48 months of age (n = 40) and typically developing (TD) children between 12-24 months of age (n = 42). The study utilized seminal experiments, the head-touch paradigm, and the hidden box to measure rational imitation. Also, the study first utilized IMETCHASD as an alternative tool in the literature to measure instructed imitation and spontaneous imitation in an interactive play context. Results showed that spontaneous imitation was associated with rational imitation in ASD.

These associations were observed after controlling for cognitive level. However, the study did not find significant correlations between instructed imitation and rational imitation in both groups. Implications for the relationship are discussed in terms of theoretical accounts for the occurrence of rational imitation and further research needs.
