Are Motor-free Visual Perception Skill Constructs Predictive of Visual-motor Integration Skill Constructs?

SummaryBackgroundTheoretical perspectives vary in considering whether visual perceptual skills and visual-motor integration (VMI) skills are related, interdependent skill sets, or two discrete skill constructs.ObjectiveThis study investigated whether motor-reduced/free visual perceptual skill constructs were predictive of motor-enhanced VMI skill constructs.MethodA total of 45 typically developing children aged 6–12 years completed the Developmental Test of Visual Perception-Second Edition (DTVP-2) and the Test of Visual Perceptual Skills-Third Edition (TVPS-3). Four multiple linear regression analyses were completed with the four DTVP-2 motor-enhanced VMI subscales being the dependent (criterion) variables and the seven TVPS-3 motor-reduced subscales being the independent variables.ResultsThe total variance accounted for in the four DTVP-2 VMI skill constructs by all the seven TVPS-3 skill constructs ranged from 29.3% to 60.10%. In the first regression analysis, the TVPS-3 Visual Sequential Memory and TVPS-3 Visual Figure–Ground constructs explained 5.40% and 4.90%, respectively, of the variance in the DTVP-2 Eye–Hand Coordination construct. In the second regression, the TVPS-3 Visual Sequential Memory and TVPS-3 Visual Figure–Ground constructs accounted for 5.60% and 3.10%, respectively, of the DTVP-2 Copying construct's variance. The third analysis revealed that the TVPS-3 Visual Memory and TVPS-3 Visual Form Constancy constructs represented 6.20% and 7.90%, respectively, of the DTVP-2 Spatial Relations construct's variance. In the fourth and final regression analysis, the TVPS-3 Visual Sequential Memory and TVPS-3 Visual Figure–Ground construct explained 14.60% and 4.90%, respectively, of the variance in the DTVP-2 Visual-Motor Speed construct.ConclusionIn the four regression analyses, specific types of motor-reduced visual perception constructs were predictive of the four specific types of motor-enhanced VMI constructs. Visual Sequential Memory and Visual Figure–Ground, specific types of motor-reduced visual perceptual constructs, were frequent and significant predictors of VMI skill constructs in children. It would appear that motor-reduced visual perceptual skills and motor-enhanced VMI skills as theoretical constructs are related and dependent on one another.
