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. Currently available in UK English only (this test is culturally biased and there are no alternative versions at present).

Graded Naming Test has been asserted to measure the following CONCEPTS

EXTERNAL DATASETS for Graded Naming Test
No external datasets have been added.
No conditions have yet been associated.

Experimental conditions are the subsets of an experiment that define the relevant experimental manipulation.


In the Cognitive Atlas, we define a contrast as any function over experimental conditions. The simplest contrast is the indicator value for a specific condition; more complex contrasts include linear or nonlinear functions of the indicator across different experimental conditions.


An indicator is a specific quantitative or qualitative variable that is recorded for analysis. These may include behavioral variables (such as response time, accuracy, or other measures of performance) or physiological variables (including genetics, psychophysiology, or brain imaging data).
