A Study On The Validity Of The Test Of Visual Perceptual Skills-Revised.

Two years ago, senior interns from the Michigan College of Optometry at Ferris State
University studied the validity of the Test ofVisual Perceptual Skills. The TVPS is a test
designed to measure a child's visual-perceptual strengths and weaknesses based on nonmotor visual perceptual testing. The seniors compared the test with several other
standardized tests of visual information processing and perceptual skills. The result of
this study was that the TVPS did not correlate with the other standardized tests (3 and 4).
Since the completion of this study, the TVPS has come out with a revised edition, which
includes some new items and deletes some old items. The revision has also been restandardized and the norms have been expanded, including standard scores, scaled
scores, T-scores, percentiles, stanines, and visual-perceptual ages for each subtest, along with perceptual quotient and median age for the total of all seven subtests (1). It was our intention to repeat the previous study using the revised test, TVPS-R, to again test itsvalidity. It was found in our study that all of the subtests seemed to correlate
significantly with age and the other standardized tests that we compared them to, with the exception of the visual sequential memory subtest.
