嗅觉系统和通过延伸的气味感知容易受到状态依赖的影响。这篇综述深入探讨了这一领域的人类行为研究,也触及了机械证据和动物工作的例子。本文综述了饱腹感对嗅觉影响的研究,强调了食物摄入量对食物气味的感知愉悦性和嗅觉决策的强大影响。其他行为状态对嗅觉的影响也进行了讨论。虽然这一领域的研究比较有限,但初步证据表明,气味感知会受到昼夜节律状态、睡眠剥夺和情绪的影响。这里描述的嗅觉功能的灵活性可以被认为是适应性的,因为它用于指导行为对具有高状态依赖价值的刺激。
The olfactory system—and odor perception by extension—is susceptible to state-dependent influences. This review delves into human behavioral research in this area, and also touches on mechanistic evidence and examples from animal work. The review summarizes studies on the impact of satiety state on olfaction, highlighting the robust effects of food intake on the perceived pleasantness of food odors and olfactory decision-making. The impacts of other behavioral states on olfaction are also discussed. While research in this area is more limited, preliminary evidence suggests that odor perception is altered by circadian state, sleep deprivation, and mood. The flexibility in olfactory function described here can be considered adaptive, as it serves to direct behavior toward stimuli with high state-dependent value.
