Using conditioned taste-aversion procedure and rats as the subjects, conditions under which preexposure to conditioned stimulus (CS) facilitates but not retards subsequent acquisition of conditioned aversion were explored. When tap water was used as the CS with animals maintained by salt water through the experiment, preexposure to CS in a context other than experimental one resulted in facilitation of the acquisition of aversion. The same effect was also obtained when salt water rather than CS (tap water) was preexposed in a different context. Simple preexposure to that context without presenting fluid had no effect.The effect of familiarity of a taste CS on the acquisition of context-dependent aversion was also studied. The results of the experiments suggested that only when subjects were given in their home cages a fluid that was identical to the CS through the experiment, conditioning context was established as the occasion setter for the acquired aversion to the CS. When animals were maintained with a fluid that differed from CS, on the other hand, it was found that conditioning context directly associated with the aversive event.

采用条件厌恶实验，以大鼠为实验对象，探讨了条件刺激对条件厌恶习得的促进作用。当实验中使用自来水和盐水饲养的动物作为禁忌物时，在非实验环境中预先接触禁忌物会促进厌恶习得。在不同的环境中预先暴露盐水而不是自来水时，也得到了同样的效果。简单地预先暴露在这种环境下而不呈现液体没有影响。我们还研究了味觉CS熟悉度对情境依赖厌恶习得的影响。实验结果表明，只有当实验对象在家里的笼子里被给予与CS相同的液体时，条件反射情境才被建立为获得性厌恶CS的场合设定者。另一方面，当动物用不同于CS的液体维持时，发现条件反射情境与厌恶事件直接相关。
