本研究的目的是确定在三个不同的任务嗅觉性能的认知相关性。共有170名男性和女性（30-87岁）在嗅觉灵敏度，辨别力和识别方面进行了评估。此外，参与者还接受了一系列认知测试，涵盖执行功能、语义记忆和情景记忆。分层回归分析表明，执行功能和语义记忆的熟练程度显着贡献的气味辨别和识别性能，而所有的认知因素证明无关的性能在气味阈值测试。这种模式的结果表明，一个人的认知能力发挥了可靠的影响，在高阶嗅觉任务的性能。
The purpose of this study was to determine cognitive correlates of olfactory performance across three different tasks. A total of 170 men and women (30-87 years of age) were assessed in olfactory sensitivity, discrimination, and identification. Also, participants were tested in a range of cognitive tests covering executive functioning, semantic memory, and episodic memory. Hierarchical regression analyses showed that proficiency in executive functioning and semantic memory contributed significantly to odor discrimination and identification performance, whereas all of the cognitive factors proved unrelated to performance in the odor threshold test. This pattern of outcome suggests that an individual's cognitive profile exerts a reliable influence on performance in higher order olfactory tasks.
