AUDITORY/VISUAL PERCEPTION AND MOTOR
DTVP-3: Developmental Test of Visual Perception–Third Edition Donald D. Hammill • Nils A. Pearson • Judith K. Voress
Visual Perceptual Index reliability is .95, with the other index reliabilities ranging from .91 to .94. Internal consistency, test–retest, and scorer reliability studies were conducted. Types of validity reported include content-description, criterion-prediction, and construct-identification. Validity with special populations, including gifted and talented and persons with learning disabilities, attention-deficit/hyperactivity disorder, traumatic brain injury, and cerebrovascular accident, is reported. Special attention was paid to making the DTVP-A:2 fair for minority groups. Validity evidence reported in the Examiner’s Manual demonstrates the test’s value for assessment of diverse groups of persons. INTERPRETATION The Examiner’s Manual provides methods for interpretation of scores. It explains how to examine the DTVP-A:2 indexes and analyze subtests. To identify intraindividual dif- ferences, the Online Scoring and Report System evaluates the significance of the dif- ferences between the four index standard scores. It also provides similar comparisons to evaluate the significance of differences between scaled scores for each subtest. Actuarial values are included. The Online Scoring and Report System calculates all the standard scores, percentiles, index comparisons, and subtest comparisons, and yields a detailed narrative report that can be edited by the examiner.

The figure serves as a model for the drawing. Subsequent figures are increasingly complex. 3. Figure–Ground . Children 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, con- fusing background. 4. Visual Closure . Children are shown a stimulus figure and asked to select the exact fig- ure from a series of figures that have been incompletely drawn. In order to complete the match, children have to mentally supply the missing parts of the figures in the series. 5. Form Constancy. Children are shown a stimulus figure and asked to find it in a series of figures. The targeted figure will have a different size, position, and/or shade, and it may be hidden in a distracting background. DTVP-3 COMPOSITES The results of the five DTVP-3 subtests are combined to form three composites: Motor- Reduced Visual Perception, Visual-Motor Integration, and General Visual Perception (combination of motor-reduced and motor-enhanced subtests). Subtests were assigned to a particular composite on the basis of the amount of motor ability required by their formats.

AGES: 4-0 through 12-11 TESTING TIME: 30 minutes ADMINISTRATION: Individual The DTVP-3 is the most recent revision of Marianne Frostig’s popular Developmental Test of Visual Perception . Of all the tests of visual perception and visual-motor integration, the DTVP-3 is unique in that its scores are reliable at the .80 level or above for all subtests and .90 or above for the composites for all age
DTVP‑A:2: Developmental Test of Visual Perception– Adolescent and Adult: Second Edition Cecil R. Reynolds • Nils A. Pearson • Judith K. Voress AGES: 11 through 79 years TESTING TIME: 20 to 30 minutes ADMINISTRATION: Individual SCORING: Online Only 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 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 The DTVP-A:2 has seven subtests (Eye–Hand Coordination, Form Constancy, Copying, Visual Closure, Visual-Motor Search, Visual-Motor Speed, Figure–Ground) 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, Motor-Reduced Visual Perception Index, Visual-Motor Intergration Index, Visual-Motor Efficiency Index). TECHNICAL FEATURES The DTVP-A:2 was standardized using a group of 1,482 adolescents and adults that closely represent the population of the United States. The seven-subtest General groups; its scores are validated by many studies; its norms are based on a large ( N = 1,035), representative sample; it yields scores for both visual perception (no motor response) and visual-motor integration ability; and it is shown to be unbiased relative to race, gender, and handedness. FEATURES OF THE DTVP-3 • New normative data were collected in 2010 and 2011 • Norms were extended upward to age 12 years 11 months • The composite scores have no floor or ceiling effects • Numerous eligibility and validity studies, including studies of the test’s sensitivity, specificity, and ROC/AUC, have been provided • The study of item bias has been expanded • The overall look of the test was updated DTVP-3 SUBTESTS The DTVP-3 has five subtests. 1 . Eye–Hand Coordination . Children are required to draw precise straight or curved lines in accordance with visual boundaries.
