The Benton Visual Retention Test (or simply Benton test or BVRT) is an individually administered test for people aged from eight years to adulthood that measures visual perception and visual memory. It can also be used to help identify possible learning disabilities among other conditions that might affect an individual's memory. The individual examined is shown ten designs, one at a time, and asked to reproduce each one as exactly as possible on plain paper from memory. The test is untimed, and the results are professionally scored by form, shape, pattern, and arrangement on the paper.

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. [1] [2] 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. [3] The test was published in 1946, and is now currently in its 5th edition.

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. 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: [5]

Method TypeDescription
AThe examinee views each design for 10 seconds before reproducing them
BThe examinee views each design for 5 seconds before reproducing them
CThe examinee views each design and is allowed to reproduce them while viewing the designs for an indefinite amount of time
DThe examinee views each design for 10 seconds, and then waits 15 seconds before reproduction begins
MThe examinee views each design for 10 seconds, and then chooses the correct design from a multiple choice of four displays

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. [6] These scores are then compared to several sets of normative data available in the manual, each representing different demographic characteristics, and conclusions can be drawn by the examiner. [7] The two different methods of scoring allow for both quantitative and qualitative analysis of an individual's test. [8]

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. [5] High amounts of perseverations, for example, suggests frontal lobe damage, while the omission of peripheral designs suggests potential brain trauma, especially in the right parietal lobe. Overall performance does not seem to distinguish those with unilateral left or right hemisphere damage. [1] Nevertheless, examiners have shown to be able to discriminate among perceptual, memory, and motor impairments based on analysis of the test results. [9] Dementia, brain lesions, thalamic stroke, and Alzheimer's disease are among the conditions that have been shown to greatly reduce an individual's BVRT score. [10] 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. [1] In 1983, the Benton Test was included in the Neurobehavioral Core Test Battery (NCTB) to identify the effects of chemical exposure on the nervous system and has since been used to assess chemical exposure in the workplace. [11] From its use in the NCTB, the Benton Test has shown sensitivity to various chemical exposures, including mercury exposure, lead exposure, and pesticide exposure. [10]

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. [5] Total errors on the test have been shown to increase with age, especially after the age of 70. [8]

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. [6] 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. [6] Despite these reports, the Benton Test has several advantages over other tests of visual memory. [8] [10] These include: a more explicit scoring system than other tests, [9] parallel-forms reliability due to the presence of multiple form sets, [8] and short administration time. Because of this, the BVRT is still widely used today for a large number of clinical conditions. [10]

The Stanford–Binet Intelligence Scales is an individually administered intelligence test that was revised from the original Binet–Simon Scale by Alfred Binet and Théodore Simon. It is in its fifth edition (SB5), which was released in 2003.

In statistics and psychometrics, reliability is the overall consistency of a measure. A measure is said to have a high reliability if it produces similar results under consistent conditions:

"It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores. Scores that are highly reliable are precise, reproducible, and consistent from one testing occasion to another. That is, if the testing process were repeated with a group of test takers, essentially the same results would be obtained. Various kinds of reliability coefficients, with values ranging between 0.00 and 1.00, are usually used to indicate the amount of error in the scores."

Neuropsychology is a branch of psychology concerned with how a person's cognition and behavior are related to the brain and the rest of the nervous system. Professionals in this branch of psychology often focus on how injuries or illnesses of the brain affect cognitive and behavioral functions.

Rehabilitation of sensory and cognitive function typically involves methods for retraining neural pathways or training new neural pathways to regain or improve neurocognitive functioning that have been diminished by disease or trauma. The main objective outcome for rehabilitation is to assist in regaining physical abilities and improving performance. Three common neuropsychological problems treatable with rehabilitation are attention deficit/hyperactivity disorder (ADHD), concussion, and spinal cord injury. Rehabilitation research and practices are a fertile area for clinical neuropsychologists, rehabilitation psychologists, and others.

<span class="mw-page-title-main">Neuropsychological test</span> Assess neurological function associated with certain behaviors and brain damage

Neuropsychological tests are specifically designed tasks that are used to measure a psychological function known to be linked to a particular brain structure or pathway. Tests are used for research into brain function and in a clinical setting for the diagnosis of deficits. They usually involve the systematic administration of clearly defined procedures in a formal environment. Neuropsychological tests are typically administered to a single person working with an examiner in a quiet office environment, free from distractions. As such, it can be argued that neuropsychological tests at times offer an estimate of a person's peak level of cognitive performance. Neuropsychological tests are a core component of the process of conducting neuropsychological assessment, along with personal, interpersonal and contextual factors.

Repeatability or test–retest reliability is the closeness of the agreement between the results of successive measurements of the same measure, when carried out under the same conditions of measurement. In other words, the measurements are taken by a single person or instrument on the same item, under the same conditions, and in a short period of time. A less-than-perfect test–retest reliability causes test–retest variability. Such variability can be caused by, for example, intra-individual variability and inter-observer variability. A measurement may be said to be repeatable when this variation is smaller than a pre-determined acceptance criterion.

<span class="mw-page-title-main">Visual memory</span> Ability to process visual and spatial information

Visual memory describes the relationship between perceptual processing and the encoding, storage and retrieval of the resulting neural representations. Visual memory occurs over a broad time range spanning from eye movements to years in order to visually navigate to a previously visited location. Visual memory is a form of memory which preserves some characteristics of our senses pertaining to visual experience. We are able to place in memory visual information which resembles objects, places, animals or people in a mental image. The experience of visual memory is also referred to as the mind's eye through which we can retrieve from our memory a mental image of original objects, places, animals or people. Visual memory is one of several cognitive systems, which are all interconnected parts that combine to form the human memory. Types of palinopsia, the persistence or recurrence of a visual image after the stimulus has been removed, is a dysfunction of visual memory.

The Bender Visual-Motor Gestalt Test is a psychological test used by mental health practitioners that assesses visual-motor functioning, developmental disorders, and neurological impairments in children ages 3 and older and adults. The test consists of nine index cards picturing different geometric designs. The cards are presented individually and test subjects are asked to copy the design before the next card is shown. Test results are scored based on the accuracy and organization of the reproductions.

The Kaufman Assessment Battery for Children (KABC) is a clinical instrument for assessing cognitive development. Its construction incorporates several recent developments in both psychological theory and statistical methodology. The test was developed by Alan S. Kaufman and Nadeen L. Kaufman in 1983 and revised in 2004. The test has been translated and adopted for many countries, such as the Japanese version of the K-ABC by the Japanese psychologists Tatsuya Matsubara, Kazuhiro Fujita, Hisao Maekawa, and Toshinori Ishikuma.

A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli, and is associated with impulsivity. Selective attention is the ability to focus on relevant stimuli and ignore competing stimuli. This skill is associated with distractibility.

<span class="mw-page-title-main">Rey–Osterrieth complex figure</span> Neuropsychological assessment

The Rey–Osterrieth complex figure (ROCF) is a neuropsychological assessment in which examinees are asked to reproduce a complicated line drawing, first by copying it freehand (recognition), and then drawing from memory (recall). Many different cognitive abilities are needed for a correct performance, and the test therefore permits the evaluation of different functions, such as visuospatial abilities, memory, attention, planning, working memory and. First proposed by Swiss psychologist André Rey in 1941 and further standardized by Paul-Alexandre Osterrieth in 1944, it is frequently used to further explain any secondary effect of brain injury in neurological patients, to test for the presence of dementia, or to study the degree of cognitive development in children.

The Test of Variables of Attention (T.O.V.A.) is a neuropsychological assessment that measures a person's attention while screening for attention deficit hyperactivity disorder. Generally, the test is 21.6 minutes long and is presented as a simple, yet boring, computer game. The test is used to measure a number of variables involving the test taker's response to either a visual or auditory stimulus. These measurements are then compared to the measurements of a group of people without attention disorders who took the T.O.V.A. This test should be used along with a battery of neuropsychological tests, such as a detailed history, subjective questionnaires, interviews, and symptom checklists before a diagnosis should be concluded.

The California Verbal Learning Test (CVLT) is one of the most widely used neuropsychological tests in North America. As an instrument, it represents a relatively new approach to clinical psychology and the cognitive science of memory. It measures episodic verbal learning and memory, and demonstrates sensitivity to a range of clinical conditions. The test does this by attempting to link memory deficits with impaired performance on specific tasks. It assesses encoding, recall and recognition in a single modality of item presentation (auditory-verbal). The CVLT is considered to be a more sensitive measure of episodic memory than other verbal learning tests. It was designed to not only measure how much a subject learned, but also reveal strategies employed and the types of errors made. The CVLT indexes free and cued recall, serial position effects, semantic clustering, intrusions, interference and recognition. Delis et al. (1994) released the California Verbal Learning Test for Children (CVLT-C). The California Verbal Learning Test-II (CVLT-II) is an updated version of the original CVLT, which has been standardized and provides normative data.

The Luria–Nebraska Neuropsychological Battery (LNNB) is a standardized test that identifies neuropsychological deficiencies by measuring functioning on fourteen scales. It evaluates learning, experience, and cognitive skills. The test was created by Charles Golden in 1981 and based on previous work by Alexander Luria that emphasizes a qualitative instead of quantitative approach. The original, adult version is for use with ages fifteen and over, while the Luria–Nebraska Neuropsychological Battery for Children (LNNB-C) can be used with ages eight to twelve; both tests take two to three hours to administer. The LNNB has 269 items divided among fourteen scales, which are motor, rhythm, tactile, visual, receptive speech, expressive speech, writing, reading, arithmetic, memory, intellectual processes, pathognomonic, left hemisphere, and right hemisphere. The test is graded on scales that are correlated to regions of the brain to help identify which region may be damaged. The Luria–Nebraska has been found to be reliable and valid; it is comparable in this sense to other neuropsychological tests in its ability to differentiate between brain damage and mental illness. The test is used to diagnose and determine the nature of cognitive impairment, including the location of the brain damage, to understand the patient's brain structure and abilities, to pinpoint causes of behavior, and to help plan treatment.

Computer-based test interpretation (CBTI) programs are technological tools that have been commonly used to interpret data in psychological assessments since the 1960s. CBTI programs are used for a myriad of psychological tests, like clinical interviews or problem rating, but are most frequently exercised in psychological and neuropsychological assessments. CBTI programs are either empirically based or clinically based. The empirically based programs, or actuarial assessment programs, use statistical analyses to interpret the data, while the clinically based programs, or automated assessment programs, rely on information from expert clinicians and research. Although CBTI programs are successful in test-retest reliability, there have been major concerns and criticisms regarding the programs' ability to assess inter-rater and internal consistency reliability. Research has shown that the validity of CBTI programs has not been confirmed, due to the varying reports of individual programs. CBTI programs are very efficient in that they save time, reduce human error, are cost effective, and are objective/reliable, yet limited in that they are not always used by adequately trained evaluators or are not integrated with multiple sources of data. As technology continues to transform our modern society, computer-based interpretation programs have the possibility to expand their software and even alleviate some of the current concerns with the programs' methodology.

The Delis–Kaplan Executive Function System (D-KEFS) is a neuropsychological test used to measure a variety of verbal and nonverbal executive functions for both children and adults. This assessment was developed over the span of a decade by Dean Delis, Edith Kaplan, and Joel Kramer, and it was published in 2001. The D-KEFS comprises nine tests that were designed to stand alone. Therefore, there are no aggregate measures or composite scores for an examinee's performance. A vast majority of these tests are modified, pre-existing measures ; however, some of these measures are new indices of executive functions.

The Purdue Pegboard Test is a psychomotor test of manual dexterity and bimanual coordination. The test involves two different abilities: gross movements of arms, hands, and fingers, and fine motor extremity, also called "fingerprint" dexterity. Poor Pegboard performance is a sign of deficits in complex, visually guided, or coordinated movements that are likely mediated by circuits involving the basal ganglia.
