Abstract
Visual-motor integration, motor coordination, and visual perception are associated with academic achievement in early school-aged children; however, our understanding of these associations in older school-aged children and children with neurodevelopmental disorders is limited. A well-characterized, clinically evaluated sample of 39 children with and without ADHD ages 8-13 (M = 10.07, SD = 1.56; 14 girls; 67.5% White/non-Hispanic) were administered standardized academic and visual-motor integration tests. Results: Backward entry regression analyses that initially included age, sex, socioeconomic status, ADHD symptoms, comorbidities, and IQ revealed that better visual perception uniquely predicted better-developed reading (β = .38) and math skills (β = .21; both p < .03), whereas better motor coordination was associated with better reading (β = .25), writing (β = .50), and math skills (β = .21 all p < .05). The integration of visual perception and motor coordination processes was uniquely associated only with math skills (β = .28; p = .007). Children with ADHD exhibited significantly lower visual-motor integration (d = 1.16) and potentially motor coordination (d = 0.51), but did not differ from Non-ADHD children in terms of visual perception (d = 0.03). These findings extend prior evidence from younger, neurotypical samples, and indicate that underdeveloped visual-motor integration and/or its subcomponents (visual perception and motor coordination) reflect unique risk factors for academic underachievement in school-aged children's math, reading, and written language skills.
