Factor Structure of Perceptual-Motor Attributes in Normal Children: A Cross-Validation

Abstract

The scores on 22 items of the Purdue Perceptual-motor Survey, administered to 567 normal school children of mean IQ 103 and mean age of 116 mo., were subjected to R-factor analysis by the method of principal factoring with orthogonal varimax rotation. The analysis led to the definition of 10 factors: J, ocular control; K, dynamic balance; L, visual-motor fluency; M, chalkboard; N, unilateral-bilateral coordination; O, upper-lower body differentiation; P, form perception; Q, developmental maturation; R, sex; and S, spatial body perception. The results provide cross-validation for previous studies on the perceptual-motor attributes of normal school children.
