一系列对大鼠的实验报告说，通过强迫在水池中游泳可以建立对味道溶液的厌恶。实验1表明，味觉和游泳的相关性是这种现象的关键因素，表明联想性（即，巴甫洛夫）这种学习的性质。实验2表明，这种学习服从巴甫洛夫定律的强度，通过显示在训练中的水浸泡的持续时间和在随后的测试中观察到的味觉厌恶之间的正相关关系。实验3表明，游泳而不是被弄湿是关键因素，因为水淋浴并没有赋予大鼠味觉厌恶。实验4发现，味觉厌恶是一个积极的功能，在训练池的水位（0，12或32厘米）。这些结果表明，由体育锻炼引起的能量消耗可能与味觉厌恶的发展有关。
A series of experiments with rats reported that aversion to a taste solution can be established by forced swimming in a water pool. Experiment 1 demonstrated that correlation of taste and swimming is a critical factor for this phenomenon, indicating associative (i.e., Pavlovian) nature of this learning. Experiment 2 showed that this learning obeys the Pavlovian law of strength, by displaying a positive relationship between the duration of water immersion in training and the taste aversion observed in subsequent testing. Experiment 3 revealed that swimming rather than being wet is the critical agent, because a water shower did not endow rats with taste aversion. Experiment 4 found that taste aversion was a positive function of water level of the pools in training (0, 12 or 32 cm). These results, taken together, suggest that energy expenditure caused by physical exercise might be involved in the development of taste aversion.
