Note on factor structure of the Frostig Developmental Test of Visual Perception

Mental deterioration, visuoperceptive disabilities and constructional apraxia in Parkinson's disease

20 patients with Parkinson's disease were tested for visuoperceptive disabilities and constructional apraxia versus a group of 20 controls. The visuoperceptive disabilities in the parkinsonians were relatively independent of mental deterioration, where present. The visuoperceptive disabilities were responsible for constructional apraxia.

Relationships among Perceptual-Motor Measures and their Correlations with Academic Readiness for Preschool Children

Kindergarten children ( N = 39) were administered 4 perceptual-motor tests and 2 academic measures in order to assess the relationship among the perceptual-motor tests and between the perceptual-motor and academic tests. Results indicated that the Shape-0 Ball Test and Frostig test were highly correlated and were good predictors of the academic measures. The dynamic balance task (stabilometer) correlated moderately with the Shape-O Ball Test, the Frostig, and the academic criteria. The Oseretsky tests did not correlate significantly with any of the other measures. Stepwise multiple correlation indicated that combining the perceptual-motor tests slightly increased their ability to predict each of the academic criteria.
