Description
The NAB Visual Discrimination Test, a stand-alone component of the Neuropsychological Assessment Battery (NAB), can be used to assess visual perception in adults without the demands of motor output.

This test evaluates deficits in visual perception using stimuli that are not amenable to verbal encoding. Administration of the assessment is brief and straightforward, using a match-to-target paradigm that is commonly used to measure visual perception and visual-spatial skills. The paradigm requires the examinee to match a target visual design from an array of four similar designs presented beneath the target.

The NAB was standardized on a national sample of 1,448 adults.

Administration and Scoring
The test takes 10-15 minutes to administer. Scores are expressed as Z-scores, T-scores, and percentile ranks. There are two equivalent forms, allowing re-administration without concern about practice effects.
