A new study has found significant similarities in the relationship between motor skills and executive function in children with autism spectrum disorder (ASD) across different cultural contexts. The research, conducted on children from the US and Taiwan, highlights the consistent link between motor skills – both fine and gross – and executive functions such as working memory and inhibition. These findings underline the importance of early interventions that focus on motor skills to potentially enhance cognitive development in young children with ASD.
The study, published in Frontiers in Public Health, examined 172 children aged between 4 and 6 years old, with 100 participants from Taiwan and 72 from the United States. Parents of these children were asked to rate their children’s motor skills and executive functions using standardised questionnaires. The Children Activity Scale – Parents (ChAS-P) was used to assess motor skills, while the Childhood Executive Functioning Inventory (CHEXI) evaluated executive functions, specifically working memory and inhibition.
The study revealed that motor skills, which include both fine motor skills like writing or cutting and gross motor skills such as running or jumping, are positively associated with executive functions in children with ASD. Executive function, which involves cognitive processes like working memory, inhibitory control, and planning, is critical for goal-directed behaviour and overall cognitive development.
Both fine and gross motor skills were found to have a significant relationship with working memory in children from both the United States and Taiwan. For instance, children who exhibited better motor skills were also rated higher in terms of their working memory capabilities. This finding aligns with the theory that motor skills and cognitive functions, particularly executive function, are interconnected and develop concurrently during early childhood.
Interestingly, while the relationship between motor skills and inhibition – a key component of executive function – was significant in children from the United States, it was not as strong in the Taiwanese cohort when a stricter significance threshold was applied. This suggests that while there may be minor variations due to cultural or environmental factors, the overall pattern of association between motor skills and executive function is consistent across cultures.
The findings have important implications for the development of early interventions aimed at children with ASD. Since motor skills are closely linked with executive function, enhancing these skills through targeted physical activities could potentially lead to improvements in cognitive functions. This is particularly crucial during the preschool years, a period identified as critical for intervention in children with ASD.
The study supports the idea that early motor behaviours play a foundational role in cognitive development. As motor skills develop, they facilitate a child’s ability to interact with their environment, which in turn promotes cognitive processes such as problem-solving and memory retention. Therefore, integrating motor skills training into early education programmes for children with ASD could be a strategic approach to supporting their overall development.
While the study found cross-cultural similarities in the association between motor skills and executive function, it also highlighted the importance of considering cultural context when designing interventions. The slight differences observed between the two countries suggest that while the fundamental relationship between motor skills and executive function is universal, the ways in which these functions are nurtured and expressed can vary depending on the child’s cultural environment.
For example, Taiwanese children might engage in different types of play or learning activities compared to their American counterparts, which could influence how motor skills and executive functions develop. This reinforces the need for culturally sensitive approaches in the development of interventions for children with ASD.
