Redundancy in perceptual-motor testing: confirmation and generalization.
The Developmental Test of Visual-motor Integration was administered to 63 children in regular classrooms and 51 children in Special Education. Prediction based on total score (r = .68) was similar to a multiple R utilizing only five scores (.67). The over-all raw test score, based on all 24 designs, correctly classified 85% of the children while a combined abbreviated score utilizing only 5 designs achieved an 80% differentiation. Results were interpreted as confirming the hypothesis of redundancy in this perceptual-motor test.
