Fifteen subjects made 450 judgments each by the method of magnitude estimation of dimethyl disulfide and hydrogen sulfide after prior exposure to various mixtures of them. Exposure to the same odorant clearly affected the perceived intensity of it (self-adaptation). By contrast, exposure to the other odorant showed at best a small effect (cross-adaptation). Consistent with this, adaptation to a mixture of the test odorant and another odorant is proportional to the amount of the test odorant in the mixture, and does not exceed that of self-adaptation. These results indicate that olfactory adaptation is specific and that the sense of smell is more robust than generally assumed.
15名受试者在预先接触二甲基二硫醚和硫化氢的各种混合物后，通过量级估计法对它们各自进行了450次判断。接触相同的气味剂明显影响了其感知强度（自身适应）。相比之下，接触另一种气味剂最多只显示出很小的影响（交叉适应）。与此一致的是，对测试气味剂和另一种气味剂混合物的适应与混合物中测试气味剂的量成正比，且不超过自身适应的程度。这些结果表明嗅觉适应是特异性的，并且嗅觉比一般认为的更具稳定性。
