Odor quality and intensity were varied to test the ability of rats to associate odor with an induced illness. Rats were allowed 10 minutes access to water on each of nine days; deodorized air was directed towards each rat's nose while drinking at familiarization and recovery sessions (days 1-5 and 7-8, respectively) and odorized air at treatment and test sessions (days 6 and 9, respectively). Each rat was injected with LiCl following its drinking period on day 6. The difference between the amount of water consumed on day 6 and day 9 gave a measure of the conditioned aversion. Only mild or no aversion occurred with odors of n-butyric acid, benzylamine, cyclohexanone, and n-butanol. Strong conditioned aversions were obtained to odors of triethylamine, 1,4-cineole, and isoamyl acetate, and the degree of aversion increased linearly with the log of odor concentration. The effect of odor quality, intensity and presentation method, and the role of the different chemoreceptor systems in the acquisition of odor aversions are discussed.
改变气味的质量和强度，以测试大鼠将气味与诱发疾病联系起来的能力。在九天中的每一天，大鼠都有10分钟的饮水时间；在熟悉和恢复阶段（分别为第1 - 5天和第7 - 8天），大鼠饮水时向其鼻子输送除臭空气，在处理和测试阶段（分别为第6天和第9天），输送加味空气。在第6天大鼠饮水期结束后，给每只大鼠注射氯化锂。第6天和第9天饮水量的差异给出了条件性厌恶的一种度量。对于正丁酸、苄胺、环己酮和正丁醇的气味，仅出现轻微或无厌恶反应。对于三乙胺、1,4 - 桉叶素和乙酸异戊酯的气味，获得了强烈的条件性厌恶反应，且厌恶程度随气味浓度的对数呈线性增加。文中讨论了气味质量、强度和呈现方式的影响，以及不同化学感受器系统在气味厌恶习得中的作用。
