GNT (Graded Naming Test)
Overview The Graded Naming Test, developed by Professor Elizabeth Warrington and Dr Pat McKenna in 1980 , has been used extensively in cognitive neuropsychology. The Graded Naming Test (GNT) avoids the problem of ceiling effects in previous naming tests by having subjects name drawings of objects in ascending difficulty. Reduced efficiency in retrieving the name of an object can be the first and only indication of impaired language functioning. This test assesses object-naming ability, but is in addition graded in difficulty to allow for individual differences. This means that it may be able to detect any word-finding difficulty even in those with an extensive naming vocabulary. Blackwell et al combined Paired Associates Learning (PAL) and the Graded Naming Test (GNT) and achieved 100% prediction of conversion of MCI to dementia, and Bird et al found it to be sensitive and useful for monitoring even small cognitive changes.

Outcome measures This test has six outcome measures, which include total correct, total errors, and normative z-score and percentile. Notes Currently available in UK English only (this test is culturally biased and there are no alternative versions at present).

VRM (Verbal Recognition Memory)
Overview Despite the general desirability of non verbal tests because of their culture free applicability, researchers and clinical studies sometimes require verbal tests, perhaps because of need to explore questions relating to language or left hemisphere function. Other verbal tests have a long history of use in psychiatric assessment and clinical studies. The Verbal Recognition Memory test, which assesses immediate and delayed memory of verbal information under free recall and forced choice recognition conditions, should provide comparable results.
	Task In the VRM test, the subject is shown a list of 12 words, one at a time, and then asked to: produce as many of the words as possible immediately following the presentation recognise the words they have seen before from a list of 24 words containing the original 12 words and 12 distractors following a delay of 20 minutes, recognise the words they have seen before from another list of 24 words containing the original list and 12 new distractors. Test modes Clinical mode and four parallel modes for repeated testing. Each mode has immediate and delayed parts.
Outcome measures The five outcome measures for VRM cover correct and incorrect responses for the recognition and free recall parts of the test. Notes Currently available in UK English only.
