(DTVP-3) Developmental Test of Visual Perception-Third Edition
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 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.
New Features:
• 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
Subtests:
• Eye-Hand Coordination: Children are required to draw precise straight or curved lines in accordance with visual boundaries.
• Copying: Children are shown a simple figure and asked to draw it on a piece of paper. The figure serves as a model for the drawing. Subsequent figures are increasingly complex.
• 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, confusing background.
• Visual Closure: Children are shown a stimulus figure and asked to select the exact figure 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.
• 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.
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 years
Administration: Individual; 30 minutes
