Description

This test assesses the ability to make fine visual discriminations. Designed in a multiple choice format, the Visual Discrimination Test (VDT) consists of 2 sample items and 16 test items that range depending on the level of difficulty. Each item has a target and four stimuli directly below the target, one of which is an identical match. The other three foils contain minor variations in placement, rotation peripheral elements, or distortion of one of the major figures. All stimuli are displayed simultaneously with no time limit. Scoring is based on a correct match (2 points), an incorrect match that includes an error involving a peripheral shape (1 point), or an incorrect match involving a major shape (0 point). Strengths of this test include its ease in administration and the relatively quick time in which it can be administered.

Psychometric Data

Normative data are relatively limited....
