摘要

The Graded Naming Test (GNT) is commonly used in clinical and research settings to assess nominal functions. However, normative data for theGNTis over 20 years old and norms for the older adult population are rather limited. Hence, confounding factors such as generational familiarity due to cultural changes need to be considered when applying the currently available norms. Moreover, normative data for the older population (80-97) are virtually absent. Such factors can be powerful confounds that can lead to incorrect interpretation of test scores. We gathered data for theGNTfrom 326 healthy controls aged between 18 and 97 years. Surprisingly, we found no decline in performance for older adults, even for the cohort aged 80-97 years (N = 40). In contrast, the youngest cohort (aged 18-29 years) performed unexpectedly below the whole sample mean. An item-by-item analysis revealed that five test items were unfamiliar to the youngest age cohort. To account for this generational familiarity effect, we created a revised 25-itemGNT. The performance of the youngest cohort on the 25-itemGNTwas no longer below the whole sample mean. The performance of the oldest cohort (80-97 years old) on the revisedGNTwas characterized by a significant decline in performance for the oldest cohort with an averageNART IQ. By contrast, those with aNART IQabove the average range did not show a decline. This suggests that factors such cognitive reserve arrested the decline in performance in the oldest age cohort with higher premorbidIQ.
