Comparison of factor structures for the Frostig Developmental Test of Visual Perception

Redundancy in Five Psychological Tests

Indices of redundancy were obtained for five psychological tests, using the full component model, and the results were compared with those previously obtained by use of the common factor model. The three indices employed appeared to yield essentially equivalent information as to the ranking of the five tests: redundancy was generally lowest in the Developmental Test of Visual Perception and highest in the Wechsler Adult Intelligence Scale. The findings provide an empirical standard for evaluating the redundancy in other tests.

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.

Investigation of the Shape-O Ball Test as a perceptual-motor task for pre-schoolers

To assess the validity of the Shape-O Ball Test, a perceptual-motor task, 38 kindergarten Ss were administered both the Shape-O Ball Test and the Frostig. A composite teacher rating (academic achievement) was collected for each S. Results indicated that the Shape-O Ball Test (1) correlates highly with the Frostig total score and significantly with all 5 subtests, and (2) is a good predictor of the academic rating.

Another look at sources of variance in the development test of visual perception

12 sets of data recently analyzed by Chissom and Thomas were reanalyzed using a different method. In contrast to the findings of the earlier study, only about 40% of the total variance of the Frostig subtests proved to be common variance. The present findings lend somewhat greater support to the premise on which the test was constructed.
