人类Ss对微弱气味（硫化氢）的敏感性在暴露于不同持续时间（0-5分钟）和浓度（4.05 × 10−7至24.40 × 10−7毫克/升）的硫化氢之前进行了研究，采用是非检测方法和专门设计的嗅觉计。适应的效果被证明，因为命中的比例是较低的适应刺激的浓度越高，当响应标准，作为衡量的假警报的比例，是相当恒定的。相比之下，命中的比例显然是独立的适应浓度的暴露的持续时间。这一发现表明，嗅觉比通常认为的更稳定。本文最后讨论了在当代检测理论中考虑适应的重要性。
The sensitivity of human Ss to a weak odor (hydrogen sulphide) following prior exposure to it varying in both duration (0–5 min) and concentration (4.05 × 10−7 to 24.40 × 10−7 mg/liter) was studied with a yes-no detection method and a specially designed olfactometer. The effect of adaptation was demonstrated, because the proportion of hits was lower the higher the concentration of the adaptation stimulus, when the response criterion, as measured by the proportion of false alarms, was fairly constant. By contrast, the proportion of hits was apparently independent of the duration of the exposure to the adaptation concentration. This finding suggests that the sense of smell is more stable than is usually believed. The paper ends with a discussion of the importance of considering adaptation in contemporary detection theory.
