DTVP-A: Developmental Test of Visual Perception–Adolescent and Adult By Cecil R. Reynolds And Nils A. Pearson And Judith K. Voress
DTVP-A: Developmental Test of Visual Perception–Adolescent and Adult
Ages: 11-0 through 74-11
Testing Time: 25 minutes
The DTVP-A is a battery of six subtests that measure different but interrelated visual-perceptual and visual-motor abilities. The battery has empirically established reliability and validity. The normative sample consists of 1,664 adolescents and adults residing in 19 states; demographic characteristics approximate the current census data. Evidence is provided to show that the test is unbiased with respect to gender and race.
The DTVP-A is the latest test based on the work of Marianne Frostig. It can be administered by psychologists, neuropsychologists, occupational therapists, physical therapists, regular and special educators, and diagnosticians who are interested in examining the visual-perceptual status and visual-motor integration skills of adolescents and adults.
The DTVP-A is especially useful in the evaluation of the neuropsychological integrity of TBI and stroke patients where right-hemisphere function may be at issue. Normed through age 75, the DTVP-A has sufficient floor or easy items to allow accurate assessment of even individuals with severe TBI and other neurologically impaired individuals. The reliability of the various subtests and index scores indicates that the DTVP-A will be sensitive to improvement over the course of treatment.
The subtests and indexes also will suggest areas of emphasis in cognitive and fine motor rehabilitation. The DTVP-A is particularly useful in distinguishing true visual-perceptual deficits from problems solely with complex eye-hand or perceptual-motor actions. The DTVP-A may also assist in differential diagnosis of various of the dementias in elderly patients, providing a baseline for normal aging changes in perception and perceptual-motor skills against which the referred patient may be referenced.
Subtest 1-Copying: Individuals are shown a simple figure and asked to draw it on a piece of paper. The figure serves as a model for the drawing.
Subtest 2-Figure-Ground: Individuals are shown stimulus figures and asked to find as many of the figures as they can on a page where the figures are hidden in a complex, confusing background.
Subtest 3-Visual-Motor Search: The individual is shown a page covered in numbered circles, randomly arranged on the page. The individual connects the circles with a line, in numerical sequence, as quickly as possible.
Subtest 4-Visual Closure: Individuals are shown a stimulus figure and asked to select the exact figure from a series of figures that have been incompletely drawn.
Subtest 5-Visual-Motor Speed: Individuals are shown (a) four different geometric designs, two of which have special marks in them, and (b) a page filled completely with the four designs, none of which have marks in them.
Subtest 6-Form Constancy: Individuals are shown a stimulus figure and asked to find it in a series of figures. In the series, the targeted figure will have a different size, position, and/or shade, and it may be hidden in a distracting background.
Special Features of the DTVP-A
Subtests were developed to be appropriate for adolescents and adults.
The normative sample reflects the current population characteristics of the United States relative to race, ethnicity, gender, geographic region, parent education, and income.
Internal consistency, stability, and interscorer reliability for all indexes are high.
Validity evidence shows that all DTVP-A subtests and indexes are useful for measuring visual-perceptual and visual-motor integration skills.
Evidence is provided to show that the test is unbiased with respect to gender and race.
