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.
Performance in verbal fluency tests show a number of consistent characteristics in both children and adults: [13] [6] [14] A declining rate of production of new items over the duration of the task, which was long discussed as following either an exponential [15] or a hyperbolic [16] time course, [7] which finally could be shown to be special cases of a unifying power function (the fused ...
In this model, a person's raw score on a test is compared to a large general population normative sample, that should ideally be drawn from a comparable population to the person being examined. Normative studies frequently provide data stratified by age, level of education, and/or ethnicity, where such factors have been shown by research to ...

Verbal memory is a recollection of verbally presented information. Several neuropsychological assessments can be administered to assess verbal memory, such as the Boston Naming Test (BNT), California Verbal Learning Test (CVLT), and the Logical Memory II subtest of the Wechsler Memory Scale-III (WMS-III). Neuropsychological assessments for ...
The effect of polysubstance dependence on learning ability is one area of interest to researchers. A study involving 63 polysubstance dependent women and 46 controls (participants who were not using substances) used the Benton Visual Retention Test (BVRT) and the California Verbal Learning Test (CVLT) to look at visual memory and verbal ability.

[4] [5] [6] The test asks the subject to write as many words as possible beginning with the letter 'S' within a 5-minute limit, then as many words as possible beginning with letter 'C' within 4 minute limit. The total number of 'S' and 'C' words produced, minus the number of rule-breaking and perseverative responses, yield the patients' measure ...
One of these was done in 2013 on a sample of 236 people, across several age ranges, ethnicity, and gender. The study found that the QT's original items had a validity coefficient range of r = .61 to r = .91 when the scores are correlated with a number of other intelligence tests, including the Weschler tests.
