MRP = Motor-Reduced Perception; VMI = Visual-Motor Integration; GVP = General Visual Perception; VC = Verbal Comprehension; PR = Perceptual Reasoning; WM = Working Memory; PS = Processing Speed; FSIQ = Full-Scale IQ; GA = General Ability; R = Reading; M = Mathematics; WL = Written Language; OL = Oral Language; TC = Total Composite.
Significance at uncorrected p values: *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001. Bold indicates correlations that survived Bonferroni correction (α = 0.05/4 = 0.0125).
