Description
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.

Additional details:
The DTVP-3 has five 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

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).
