嗅知觉性质的行为实验数据集

人类空间导航依赖于我们双眼和双耳信息的输入。尽管我们也有两个鼻孔，但几乎没有实证表明鼻孔间气味信息差异在不涉及三叉神经系统的情况下产生人类嗅觉的方向性。本研究中，我们通过正式的心理物理测结合光流刺激（视觉场景中表面元素的表观运动模式）证明，非三叉刺激的气味剂的适度鼻空间浓度差异一致的使接受者感知的自我运动方向偏向于较高浓度一侧，尽管他们无法用语言描述哪个鼻孔闻到的气味更强烈。我们进一步表明，该效应取决于呈现在鼻孔间气味浓度的比例，而不是简单的数值差异。总而言之，我们的研究结果为人类可以立体的闻气味，并在空间导航中在意识下层面利用立体嗅觉线索提供了行为证据。

Human spatial navigation relies on inputs from both eyes and ears. Although humans possess two nostrils, there is little empirical evidence that inter-nostril differences in odor information can confer directional olfactory perception in humans without involving the trigeminal nervous system. In this study, we employed formal psychophysical measurements combined with optic flow stimuli (apparent motion patterns of surface elements in visual scenes) to demonstrate that modest inter-nostril concentration differences of non-trigeminal odorants consistently biased participants' perceived self-motion direction toward the side with the higher odor concentration, even though they could not verbally report which nostril detected a stronger odor. We further demonstrated that this effect depends on the ratio of odor concentrations between the two nostrils, rather than simple numerical concentration differences. Collectively, our findings provide behavioral evidence that humans are capable of stereosmic olfaction, and utilize stereosmic olfactory cues for spatial navigation at a subconscious level.
