From action to interaction: exploring the contribution of body motion cues to social understanding in typical development and in autism spectrum disorders.
Kids with autism struggle to read social intent from body motion alone—teach gestures explicitly and check motor skills.
01Research in Context
What this study did
Centelles et al. (2013) showed kids short cartoons of two people talking.
Only the moving dots of the speakers' bodies were visible.
Children with autism and typically developing peers watched the clips and picked the label that best described what the people were doing.
What they found
Kids with autism sorted the clips less accurately than matched peers.
They struggled to read social intent from body motion alone.
The gap points to a body-motion social perception deficit.
How this fits with other research
Fitzpatrick et al. (2017) seems to disagree. They found that better social motor synchronization linked to higher social-cognitive skills in autism.
The studies differ in what they measure. Laurie looked at decoding silent clips; Paula measured real-time movement matching.
Craig et al. (2018) extends the link. Preschoolers with autism plus intellectual disability scored lower on aiming and catching, and those motor gaps tracked with social-communication impairment.
Oliveira et al. (2023) shows why this matters. Locomotion and balance skills predicted how often 5- to 10-year-olds with autism joined home, school, and community activities.
Why it matters
If a child misreads body language, social skills training should include explicit video modeling of gestures, stance shifts, and personal space.
Add simple aiming and catching games to your plan; they may boost both motor and social growth.
Check participation at home and recess—poor movers often sit out, missing natural social practice.

03Original abstract
Two studies investigated whether typically developing children (TD) and children with autism spectrum disorders (ASD) were able to decide whether two characters were communicating or not on the basis of point-light displays. Point-lights portrayed actors engaged or not in a social interaction. In study 1, TD children (4-10 years old; n = 36) grasped social intentions from body language, with a notable improvement around 7/8. In study 2, children with ASD (6-12 years old; n = 12) could categorize the point-light displays at above-chance levels, but performed less efficiently, especially for the social interaction displays, than TD children (matched to chronological and non-verbal mental age, 6-12 years old; n = 24). An action representation deficit is discussed in relation to a social representation deficit and it is suggested that these deficits might be linked to altered maturational process of the mirror system in ASD.
