RESUMO
Difficulty with implicit learning plays an important role in the symptomology of autism spectrum disorder (ASD). However, findings in motor learning are inconsistent. This study evaluated implicit sequence learning and its relationship with motor ability in children with and without ASD. We adopted a classic serial reaction time task with a retention task and three awareness tests. The Movement Assessment Battery for Children was administered to assess children's motor ability. Significant learning differences between children with and without ASD were only found in retention but not immediately after the serial reaction time task. These findings suggest that the impaired implicit learning in ASD is characterized as impaired consolidation where the relatively permanent changes are missing. Exploratory moderation analyses revealed a significant relationship between implicit learning and motor ability for individuals with faster response time. We argue the importance of response speed for optimal learning and should be weighted more for future intervention in children with ASD.

Several recent studies revealed that physical activity programs that focus on fundamental motor skills could enhance both motor and social performance. The purpose of this pilot was to explore whether the social impairment of Autistic Spectrum Disorders (ASD) moderated the motor outcomes of a physical activity program. Nine children with ASD attended a 2-week program that adopted the Classroom Pivotal Response Teaching. Significant improvements on motor skills were found in all participants. Furthermore, children with more social impairment demonstrated greater motor improvement in comparison to those with less social problems. Findings suggest the importance of social factors on the outcomes of physical activity programs and the interplays between social and motor domains in ASD interventions.
