About This Product
BY NANCY A. MARTIN, PHD
This test replaces two previous, age-specific measures of visual-motor ability--the TVMS-R and TVMS-UL. It offers easier administration, greater convenience, and considerable economy.
The new TVMS-3 uses design copying to find out how well individuals can coordinate visually guided, fine-motor movements. Distortions and inaccuracies in copied designs help identify deficits in visual perception, motor planning, and execution.
The test-taker is asked to reproduce 39 increasingly complex geometric designs--each in a single attempt, without sketching or tracing. Scoring is quick and easy--rulers and protractors are no longer needed. The Record Form lists common errors for each design, and the Manual presents detailed scoring guidelines.
Nine kinds of errors are identified: Incorrect Closures; Incorrect Angles; Line Quality; Line Lengths; Line Connections; Modification of Size or Part; Addition or Deletion of a Part; Rotation or Reversal; and Shape Overlap. By analyzing these errors, you get a detailed evaluation of visual-motor skills. When used in conjunction with a visual perception test, the TVMS-3 can differentiate visual-motor and perceptual impairments.
