The California Verbal Learning Test (CVLT) [1] 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 ...
André Rey (1906–1965) was a Swiss psychologist who first developed the Rey-Osterrieth Complex Figure and the Rey Auditory Verbal Learning Test. Both tests are widely used in neuropsychological assessment. Rey was considered to be a pioneer in clinical psychology, child psychology, and neuropsychology.
There is no assessment of executive function, phonemic fluency, or motor responses. It takes about half an hour to administer. [3] It was originally introduced in the screening for dementia, but has also found application in other situations, [3] such as hepatic encephalopathy. [4]
The Auditory-Verbal Learning Test is a memory test that assesses recall of heard lists of words in single and multiple trials. Caffeinated subjects recalled fewer words than control subjects, and caffeinated subjects showed a greater deficit in recalling the middle- to end-portions of the lists. [3]
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 ...
The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
The second half of this test is a "high brain stimulation task" in which targets are frequently presented. This task pulls for "errors of commission" since a person may expect to see a target and impulsively respond. The auditory version of the T.O.V.A. is the same paradigm using two easily recognized tones as the target and non-target stimuli. [8]
When test subjects are presented with auditory versus visual word cues, they only perform worse on directed recall of a spoken word versus a seen word, and perform about equally on implicit free-association tests. Within auditory stimuli, semantic analysis produces the highest levels of recall ability for stimuli.
