Benton Visual Retention Test

History

Arthur Benton was a psychologist who worked with neurologist Morris Bender during his military assignment to the San Diego Naval Hospital. His experiences in the treatment of servicemen who had traumatic brain injuries led to his development of the Benton Visual Retention Test. Dr. Benton developed the test to provide a shorter assessment for immediate nonverbal memory to supplement the popular digit span test, and selected a format that was resistant to both emotional and subject-tester influence. The test was published in 1946, and is now currently in its 5th edition.

Testing

Test format

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. The examinee is given a booklet containing 10 blank pages on which they reproduce the designs. These design are used to gauge the examinee's visual perception and memory, and can be administered five different ways. These five methods are as follows:

In every method except for Administration C, the original design is hidden before reproduction begins.

Test scoring

The test can be scored two ways. First method: The number of correct score is calculated based on an all-or-nothing approach; points are awarded if the reproduction of the design matches the original. Second method: The number of error score, on the other hand, is calculated based on the number and type of errors made for each design. The major categories for these errors are omissions, distortions, perseverations, rotations, misplacements, and size errors. The two different methods of scoring allow for both quantitative and qualitative analysis of an individual's test.

Uses

The Benton Test is sensitive to many forms of brain impairments and diseases, but it is difficult to diagnose a particular disease through the test. In fact, according to the test manual, a high number of a single category of error should not be used as a diagnosis, but should lead to further testing. Both the copy and memory versions of the test are especially sensitive to dementia, and may help identify individuals who are at risk for developing Alzheimer's later. In addition, learning disabilities among children are able to be identified through the Benton Test. From its use in the NCTB, the Benton Test has shown sensitivity to various chemical exposures, including mercury exposure, lead exposure, and pesticide exposure.

Psychometric properties

According to the Benton Test manual, test-retest reliability of the Benton Test is 0.85, and alternate form reliabilities range from 0.79 to 0.84. Correlation between immediate and delayed memory recall (Administration type A and D, respectively) ranges from 0.40 to 0.83, depending on the combinations of forms used. Included with the manual are standardized results for children, adolescents, and adults, though each administration method have their own standardization data.

Criticisms and validity

The Benton Test has been criticized by test's requirement of the examinee's IQ or estimated IQ, which can be difficult to obtain if the examinee is in a poor condition. In addition, data from studies that look at the viability of retesting a patient have shown conflicting results; some studies show no difference in scores after time has passed between two tests, while other studies show a difference. parallel-forms reliability due to the presence of multiple form sets, and short administration time. Because of this, the BVRT is still widely used today for a large number of clinical conditions.
