Implicit and explicit motor learning: Application to children with Autism Spectrum Disorder (ASD).
Kids with autism can pick up motor patterns without conscious awareness, so let the hands practice while the mouth stays quiet.
01Research in Context
What this study did
Izadi-Najafabadi et al. (2015) watched two groups of late-elementary kids play a computer game. One group had autism, the other group did not.
The game used a serial-reaction-time task. Kids pressed buttons as fast as they could when lights popped up. Some patterns repeated, so kids could learn without knowing it. Later, the team asked the kids to explain the pattern. This tested explicit learning.
What they found
Kids with autism got faster on the hidden pattern, just like typical kids. Their hands learned even when their minds did not notice the rule.
When the team asked them to state the pattern, the typical kids could talk about it. The autistic kids could not. Their explicit learning was missing.
How this fits with other research
Sharp et al. (2010) saw the same intact hidden learning in older, high-functioning teens and adults with autism. Sara’s team shows the skill is already there in younger kids.
Sparaci et al. (2015) also found equal learning on a different motor game, but they saw odd movement paths. Together, the papers say: hands can learn, yet the route looks different.
Gowen et al. (2013) reviewed many studies and concluded motor learning itself is largely intact in autism. Sara’s split between hidden and conscious learning gives that claim a finer edge.
Why it matters
For your next session, teach motor skills with repetition, rhythm, and minimal talk about rules. Let the learner’s body do the noticing. Save the verbal explanations for another goal.

03Original abstract
AIMS AND OBJECTIVES: This study aims to determine whether children with Autism Spectrum Disorder (ASD) are capable of learning a motor skill both implicitly and explicitly. METHODS: In the present study, 30 boys with ASD, aged 7-11 with IQ average of 81.2, were compared with 32 typical IQ- and age-matched boys on their performance on a serial reaction time task (SRTT). Children were grouped by ASD and typical children and by implicit and explicit learning groups for the SRTT. RESULTS: Implicit motor learning occurred in both children with ASD (p=.02) and typical children (p=.01). There were no significant differences between groups (p=.39). However, explicit motor learning was only observed in typical children (p=.01) not children with ASD (p=.40). There was a significant difference between groups for explicit learning (p=.01). DISCUSSION: The results of our study showed that implicit motor learning is not affected in children with ASD. Implications for implicit and explicit learning are applied to the CO-OP approach of motor learning with children with ASD.
