The Benton Visual Retention Test is composed of 3 sets, or forms, of 10 designs (each 8.5 × 5.5 in.) that measure the examinee's visual and memory abilities as well as a set of alternate designs for repeated tests. [4] The examinee is given a booklet containing 10 blank pages on which they reproduce the designs.

[9] While agnosics suffer from severe deficits, patients' visual acuity and other visual abilities such as perceiving parts and colours remain intact. [6] Deficits seem to occur because of damage to early-level perceptual processing. [9]
The higher cut-off score has both high specificity and sensitivity and is at least five times more likely to have come from a dementia patient than without.
