Insights
Children with developmental coordination disorder (DCD) show lower motor and cognitive skills compared to peers. Early assessment and intervention are crucial for addressing these cognitive-motor difficulties.
Area of Science:
- Developmental Psychology
- Neuroscience
- Motor Control
Background:
- Developmental Coordination Disorder (DCD) affects motor skills in children.
- Information processing theories, like PASS, offer frameworks to understand cognitive-motor links.
Purpose of the Study:
- To investigate differences in motor and cognitive abilities between children with and without DCD.
- To explore the relationship between cognitive processes and motor skills in preschoolers.
Main Methods:
- Utilized the PASS theory of information processing.
- Assessed 108 preschoolers (54 with DCD, 54 without) aged 5-6.
- Employed the Movement Assessment Battery for Children, Bruininks-Oseretsky Test, and Das-Naglieri Cognitive Assessment System.
Main Results:
- Children with DCD performed significantly lower on all assessed motor and cognitive tasks.
- Significant correlations found between cognitive processes and motor skills.
- Simultaneous processing correlated with manual dexterity; planning correlated with balance in non-DCD group.
Conclusions:
- Early identification of cognitive-motor deficits in DCD is possible through targeted assessments.
- Intervention can mitigate academic and daily life challenges associated with DCD.
Abstract:
The current study adopts the PASS theory of information processing to investigate the probable differences in specific motor and cognitive abilities between children with and without developmental coordination disorder (DCD). Participants were 108 5- and 6-year-old preschoolers (54 children with DCD and 54 children without DCD). The Movement Assessment Battery for Children assessed motor function. Running speed and agility were measured using the Bruininks-Oseretsky Test of Motor Proficiency. Finally, the Planning, Attention and Simultaneous Scales from the Das-Naglieri Cognitive Assessment System evaluated cognitive ability. Children with DCD differed significantly from those without DCD performing at a lower level on all motor and cognitive tasks. A correlation analysis revealed significant relationships between cognitive processes and motor skills. Simultaneous cognitive processing and manual dexterity were significantly correlated for both groups. Furthermore, a significant relationship was revealed between planning cognitive processing and balance for the non-DCD group. Thus, early assessment might identify specific cognitive-motor difficulties. Furthermore, early intervention might prevent some of the developmental comorbidities in the academic and everyday lives of children with movement difficulties.
