The?Developmental Test of Visual Perception?Adolescent and Adult: Second Edition?(DTVP-A:2) is a well-researched, norm-referenced measure of general visual-perceptual skills. The DTVP-A:2 was designed to measure visual-perception and visual-motor abilities in individuals ages 11-0 through 79-11.
The?Developmental Test of Visual Perception?Adolescent and Adult: Second Edition?(DTVP-A:2) is a well-researched, norm-referenced measure of general visual-perceptual skills. The DTVP-A:2 was designed to measure visual-perception and visual-motor abilities in individuals ages 11-0 through 79-11. The DTVP-A:2 provides practitioners with valid and reliable scores that measure adolescent and adult strengths and weaknesses in important areas of visual perception. In particular, it enables examiners to make comparisons between visual perceptual, visual-motor, and visual-motor efficiency skills.
The?Online Scoring and Report System?included in the kit allows the examiner to enter the examinee?s subtest raw scores and quickly generate Standard Summary and Detailed Narrative reports that include standard scores, percentiles, and intra-individual comparisons; the reports can be edited, printed, or saved, and results copied into your personalized report as needed.
DTVP-A: 2 Scores
The DTVP-A:2 has seven subtests that measure different but interrelated visual-perceptual and visual-motor abilities along with four index scores. The test provides standard scores with a mean of 100 and standard deviation of 15 for the four composite index scores.
General Visual Perceptual Index (GVP)?The GVP is the best measure of what the majority of people mean when they say ?visual perception.? It consists of information about visual-perceptual ability derived from three types of testing formats (i.e., visual-motor integration, motor-reduced formats, and visual-motor efficiency). Data from seven subtests?each of which measures a different type of visual perception in a different manner?contribute to the GVP.
Motor-Reduced Visual Perception Index (MRP)?The MRP is the ?purest? and most direct measure of visual perception, in that only minimal motor skills (e.g., pointing) are required to show perceptual competence.
Visual-Motor Integration Index (VMI)?The VMI measures visual-perceptual skills by assessing an individual?s skills in performing complex eye?hand coordination tasks.
Visual-Motor Efficiency Index (VME)?The VME is a measure of individuals? speed and accuracy in combining their visual perception of the field designated for performing the task and their ability to scan and search the field while performing what are simple but refined fine-motor movements.
The seven subtests measure specific content and skills and provide scaled scores with a mean of 10 and standard deviation of 3.
