The RAVLT requires an individual to remember a list of 15 words repeated over five trials. Then another list of 15 words is presented to potentially interfere with the first list. After a 30 minute delay the individual is again asked to recall the original word list. Finally, a recognition trial is administered using a story or list of words and asking the examinee to check of words from the original list. The RAVLT provides T-score and Standard Score data and provides meta-norms as well as various specific alternative norms. The RAVLT also provides normative data for those aged 13 and older.

The Rey Complex Figure Test is a neuropsychological measure employed in the assessment of visuospatial memory (the ability to visually perceive objects and the spatial relationships among objects) and constructional ability (the ability to form designs, objects, or materials with the hands, under visual guidance) for adults aged 18 through 89 years. Four separate trials structure the RCFT beginning with a Copy trial in which the examinee copies a complex figure from a stimulus card, then after three minutes the examinee draws the figure from memory in the Immediate Recall trial. 30 minutes after the Copy trial is completed the examinee again draws the figure from memory in the Delayed Recall trial. Finally, a Recognition trial is completed immediately after the Delayed Recall trial where the examinee tries to recognize 12 of 24 items which are from the stimulus figure with the other 12 items serving as distractors. The RCFT converts raw scores for the Immediate Recall, Delayed Recall, and Recognition Total Correct scales into T scores and corresponding percentile scores. The RCFT converts raw scores for the Immediate Recall, Delayed Recall, and Recognition Total Correct scales into T scores and corresponding percentile scores. Memory profile patterns can also be discerned from the pattern of scores across these three RCFT scales.

The Test of Memory and Learning is a comprehensive measure of memory ability in individuals aged 5 years old up to 19 years, 11 months, 30 days old. The test is composed of 10 core subtest, five verbal which form the Verbal Memory Scale, and five nonverbal that form the Nonverbal Memory Scale. Four supplementary subtests are included. Core Indexes include: Verbal Memory Index (VMI), Nonverbal Memory Index (NMI), Composite Memory Index (CMI), and the Delayed Recall Index (DRI). Additionally five supplementary indexes are included: Sequential Recall Index (SRI), Free Recall Index (FRI), Associative Recall Index (ARI), Learning Index (LI), and the Attention/Concentration Index (ACI). The TOMAL uses standard scores for all indexes with a mean of 100 and standard deviation of 15.

The Wechsler Memory Scale – Fourth Edition (WMS-IV) is an individually administered assessment of memory functions. The WMS-IV is divided into two batteries; the first is an Adult battery that covers ages 16 to 69 years and the second is an Older Adult battery which covers ages 65 to 90 years. Information is presented through the use of standard scores with a mean of 100 and standard deviation of 15 for each index, scaled scores with a mean of 10 and standard deviation of 3 for each subtest as well as cumulative percentages which are sorted into seven percentile groups. In addition there are contrast scaled scores and process scaled scores that can be computed. The contrast scaled scores are used to adjust one score based on performance on another particular variable which provides a different scope in understanding performance. Process scaled scores are available for some subtests as well and provide information on specific aspects of performance.
