Abstract
Developmental coordination disorder (DCD) is a neurodevelopmental disorder characterized by motor impairments that negatively influence daily life and academic performance, assumed to originate from a deficit in automatization of motor skills. Previous research has demonstrated that children with this disorder have significant problems with dual-task performance, possibly due to cognitive-motor interference and contending attentional resources. Cultural differences regarding the prevalence, gender distribution, and etiology of the disorder were found by previous research. The present study compares the dual-task performance of 140 children from the Netherlands and Brazil, of which 64 were classified as having DCD and 76 as typically developing children, on motor-motor and cognitive-motor dual-task paradigms. The performance on single-tasks was significantly lower in children with DCD than typically developing children in the entire sample, the Dutch sample, but not in the Brazilian sample. Analyses comparing dual-task performance with single-task performance across groups and cultures remained insignificant; however, it was found that performance patterns did differ across cultures. Dual-task costs were found to facilitate and interfere with performance similarly across groups and cultures. Based on the statistical results and behavioral observations made during assessments, the present study found evidence for the automatization deficit hypothesis in children with DCD, evidence for competing attentional resources, and cognitive-motor interference in the entire sample. Future interventions should be aimed at the automatization deficit and incorporate visual feedback. The cultural differences found, highlight the need for ecological studies and aimed interventions in developing countries, not only towards children with DCD but also for typically developing children.
