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.
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 "dichotic fused words test" (DFWT) is a modified version of the basic dichotic listening test. It was originally explored by Johnson et al. (1977) [25] but in the early 80's Wexler and Hawles (1983) [26] modified this original test to ascertain more accurate data pertaining to hemispheric specialization of language function.
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.
