About This Product
BY NANCY A. MARTIN, PHD
This Third Edition covers the age range 4 through 18 previously served by the two earlier editions (TVPS-R and TVPS-UL-R). The TVPS-3 is an easy-to-use assessment to determine a child's visual perceptual strengths and weaknesses. Visual perception is an important ability that enables one to make sense out of what is seen (in contrast to visual acuity tests that determine just that something was seen by the individual). The TVPS-3 includes the following subtests:
- Visual Discrimination
- Visual Memory
- Visual-Spatial Relationships
- Form Constancy
- Visual Sequential Memory
- Visual Figure-Ground
- Visual Closure
The TVPS-3 was designed to be used by occupational therapists, psychologists, education diagnosticians, developmental optometrists, learning specialists, and other assessment professionals.
The TVPS-3 utilizes black-and-white designs as stimuli for all of the perceptual tasks. Within each area, the items are arranged in a developmental progression and are presented in a multiple-choice format. Item responses are made vocally (by saying the letter of the response choice) or by pointing. This format is ideal for children who may have impairments in motoric, speech, hearing, neurological, or cognitive functions. There are 16 plates for each perceptual area; each area is normed separately so that the clinician may reliably differentiate the various visual perceptual processes. The plates are spiralbound with foldout easels to facilitate presentation.
Analysis of the subtest score patterns provides functional comparisons that enable the clinician to make a comprehensive diagnosis of a child's perceptual abilities separate from motor skills. The manual includes a completed and scored protocol for instructional purposes.
The TVPS-3 also provides new, nationally stratified norms based on data from over 2,000 children. It may be administered to individuals or small groups. It is untimed and takes about 30 to 40 minutes to complete, depending on the age and abilities of the child. No basals are needed, and ceilings are used to minimize any fatigue effects. Scoring is quick and easy, completed in about 5 minutes. The front of the scoring form provides a convenient graphic to display subtest scores.
Scores are presented as individual subtest scaled scores and one overall standard score; this allows the TVPS-3 scores to be compared easily to scores from other standardized tests. Percentile ranks and age equivalents are also provided.
