Executive difficulties in Developmental Coordination Disorder: Methodological issues and future directions

Motor skills and cognition have often been studied separately, but there is increasing understanding of the close relationship between these abilities over development. Motor coordination difficulties are central to the diagnosis of Developmental Coordination Disorder (DCD), and recent evidence suggests that certain cognitive processes, known as ‘executive functions’, may be affected in individuals with this neurodevelopmental disorder. In this article, we review the research concerning executive functions in DCD, considering behavioural, neuroimaging and questionnaire studies of a range of processes. We highlight methodological issues relating to our current understanding of executive functioning difficulties in DCD, including problems with interpretation of results based on the tasks used. We suggest future directions for research in this area, including the relationship of laboratory research to interventions within ‘real-world’ contexts
