Description:
This Third Edition covers all of the ages 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 spiral bound 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.
