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.
