Visual-motor perception in students with attention deficit with hyperactivity disorder.

Area of Science:

• Neuroscience
• Developmental Psychology
• Educational Psychology

Background:

• Attention Deficit with Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder impacting executive functions.
• Visual-motor perception is crucial for academic tasks like writing and reading.
• Previous research suggests potential links between ADHD and visual-motor challenges.

Purpose of the Study:

• To characterize and compare the visual-motor perception skills of students diagnosed with ADHD.
• To contrast the visual-motor performance of students with ADHD against peers with strong academic records.

Main Methods:

• A cohort of 40 elementary school students (2nd-5th grade) participated.
• Participants were divided into two groups: 20 with ADHD (GI) and 20 with good academic performance (GII), matched for age, gender, and schooling.
• The Developmental Test of Visual Perception, Second Edition (DTVP-2) was administered to all students.

Main Results:

• Students with ADHD (GI) demonstrated significantly lower performance in spatial position and visual closure compared to the control group (GII).
• An inferior age-equivalent score in reduced motor perception was observed in the ADHD group.
• These findings highlight specific areas of visual-motor deficit in students with ADHD.

Conclusions:

• Difficulties in visual-motor perception among students with ADHD are likely secondary to inattentive symptoms.
• Inattention directly interferes with visual-motor performance, rather than indicating a primary perceptual deficit.
• Interventions addressing inattention may improve visual-motor skills in students with ADHD.
