工作记忆，认知速度和言语检索的措施在多大程度上与嗅觉测试的性能进行了评估，在138名老年人的样本。结构方程建模技术表明，言语提取困难显着影响性能的宾夕法尼亚大学的识别测试（UPSIT）。此外，较差的工作记忆和缓慢的认知速度显着影响UPSIT和苯乙醇阈值测试的性能。嗅强度测试不受任何认知变量的影响。在不考虑认知障碍的情况下，气味阈值和识别任务可能会高估嗅觉损失。
The extent to which measures of working memory, cognitive speed, and verbal retrieval are associated with performance on tests of olfaction was evaluated in a sample of 138 older adults. Structural equation modeling techniques indicated that verbal retrieval difficulties significantly affect performance on the University of Pennsylvania Smell Identification Test (UPSIT). Further, poor working memory and slow cognitive speed significantly affect performance on the UPSIT and the phenyl ethyl alcohol threshold test. The Sniff Magnitude Test was not influenced by any of the cognitive variables. Odor threshold and identification tasks may overestimate olfactory loss when cognitive impairment is not taken into account.
