Three experiments explored the olfactory and the common chemical attributes of sensations produced by various concentrations of n-butyl alcohol. These two attributes combine in an almost-linear fashion to produce the overall perceived intensity of the stimulus. Common chemical intensity makes only a small contribution to overall magnitude at low concentrations, but its proportional contribution increases with concentration. In like manner, speed of response (i.e., reciprocal of reaction time) to the common chemical attribute increases more rapidly than that to odor. Nevertheless, odor always makes its appearance sooner than the common chemical attribute, even when the two attributes are matched in perceived magnitude. Repeated inhalations cause odor intensity to decrease slightly but cause common chemical intensity to increase dramatically. The results obtained from the normal subjects studied here agree with those obtained from subjects with unilateral destruction of the trigeminal nerve.
三项实验探究了不同浓度正丁醇产生的嗅觉和共同化学属性的感觉。这两种属性以几乎线性的方式结合，以产生刺激的整体感知强度。在低浓度时，共同化学强度对总体大小的贡献很小，但其比例贡献随浓度增加。同样，对共同化学属性的反应速度（即反应时间的倒数）比对气味的反应速度增加得更快。然而，即使两种属性在感知强度上相匹配，气味总是比共同化学属性出现得更早。反复吸入会使气味强度略有下降，但会使共同化学强度大幅增加。此处研究的正常受试者所得结果与三叉神经单侧受损受试者所得结果一致。
