Object-directed imitation in autism spectrum disorder is differentially influenced by motoric task complexity, but not social contextual cues.
Simplify motor demands, not social cues, when teaching imitation to kids with autism.
01Research in Context
What this study did
Lacey and her team watched the preschoolers copy actions with toys.
Half had autism, half were typical kids.
They changed two things: how hard the action was (easy vs tricky), and how the adult acted (friendly vs cold).
What they found
Kids with autism copied easy moves just fine.
When the moves got hard, they fell behind.
Typical kids did the same no matter what.
Surprise: the adult's mood made no difference to either group.
How this fits with other research
Stieglitz Ham et al. (2008) saw the same thing in older kids.
They found kids with autism messed up meaningless gestures because they twisted body parts wrong.
Both studies say the problem is in the body, not the social brain.
Lloyd et al. (2013) adds that motor delays in autism grow fast.
Their toddlers fell further behind every six months.
This helps explain why hard moves trip up the kids in Lacey's study.
Annunziata et al. (2024) tried robot teachers to cut social noise.
Only 4 of the kids learned, showing motor practice helps when social stuff is held steady.
Why it matters
Stop adding extra smiles or big reactions when you teach imitation.
Instead, break hard actions into tiny steps.
Start with one simple move, then add the next.
Your kids will learn faster because their bodies can keep up.

03Original abstract
We examined the role of social motivation and motor execution factors in object-directed imitation difficulties in autism spectrum disorder. A series of to-be-imitated actions was presented to 35 children with autism spectrum disorder and 20 typically developing children on an Apple® iPad® by a socially responsive or aloof model, under conditions of low and high motor demand. There were no differences in imitation performance (i.e. the number of actions reproduced within a fixed sequence), for either group, in response to a model who acted socially responsive or aloof. Children with autism spectrum disorder imitated the high motor demand task more poorly than the low motor demand task, while imitation performance for typically developing children was equivalent across the low and high motor demand conditions. Furthermore, imitative performance in the autism spectrum disorder group was unrelated to social reciprocity, though positively associated with fine motor coordination. These results suggest that difficulties in object-directed imitation in autism spectrum disorder are the result of motor execution difficulties, not reduced social motivation.
