尽管许多研究旨在了解这一现象，但关于如何在行为上感知二元气味混合物仍存在一些争议。啮齿动物对二元混合物的感知是阐明如何感知更复杂的气味混合物的第一步。到目前为止，研究已经检验了成分相似程度、嗅觉感受器重叠、成分的相对浓度，甚至嗅觉丰富如何影响二元混合物的行为知觉。这些研究的目的是将二元混合物归类为3个刚性类别中的1个，但对于特定混合物属于哪一类，结果往往相互冲突。在这篇文章中，作者使用习惯化/辨别范式来确定当两种成分的浓度一起变化时，大鼠对感知相似或不相似成分的二元混合物中的一种成分的感知是否会发生变化。作者发现，对二元混合物的感知随着成分浓度的变化而改变，因此一种二元混合物可以根据成分强度被不同地分类。(心理信息数据库记录(C)2016 APA，保留所有权利)
Some controversy still exists as to how binary odorant mixtures are behaviorally perceived, despite many studies aimed at understanding this phenomenon. Binary mixture perception by rodents is a first step in elucidating how more complex odor blends may be perceived. Research thus far has examined how the degree of component similarity, olfactory receptor overlap, relative concentration of components, and even olfactory enrichment affect the behavioral perception of binary mixtures. These studies have aimed to categorize binary mixtures into 1 of 3 rigid categories, but often the results conflict as to which category a particular mixture belongs. In the present article, the authors used a habituation/discrimination paradigm to determine whether rats' perception of one component of a binary mixture of either perceptually similar or dissimilar components changed when the concentration of both components was varied together. The authors found that perception of a binary mixture changed with changing component concentration, such that one binary mixture could be categorized differently depending on component intensity.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
