The relationship between motor coordination, executive functioning and attention in school aged children

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatrics

Background:

• Attention deficit hyperactivity disorder (ADHD) and developmental coordination disorder (DCD) frequently co-occur.
• Executive function (EF) deficits are common in ADHD and may contribute to DCD.
• Understanding the relationship between EF and motor skills is crucial for effective interventions.

Purpose of the Study:

• To investigate the association between executive function and motor abilities in children.
• To determine if executive function deficits contribute to motor coordination issues.
• To explore the overlap in cognitive processes affected by ADHD and DCD.

Main Methods:

• Recruited 238 children (ages 6-15).
• Assessed motor ability using the McCarron Assessment of Neuromuscular Development (MAND).
• Measured inattention (Child Behavior Checklist - CBCL), executive functions (response inhibition, working memory, planning), and reaction time.

Main Results:

• Motor ability significantly predicted performance speed.
• Inattention was associated with performance variability.
• Limited overlap was found in the specific cognitive processes affected by motor and attention problems.

Conclusions:

• Motor ability and inattention impact different aspects of cognitive performance in children.
• While ADHD and DCD are comorbid, their underlying cognitive mechanisms may differ.
• Further research is needed to clarify the distinct and shared pathways in these neurodevelopmental disorders.
