摘要 车轮转动已被证明会诱发条件性味觉厌恶（CTA）。目前的实验测试了平坦的圆形小巷中的活动是否也会诱发 CTA。在两个实验的每一个中，一组大鼠接受配对暴露于一种调味溶液和不配对暴露于第二种调味溶液，第二组反之亦然。在配对暴露期间，让大鼠接触调味溶液 10 分钟，然后将其限制在小巷中 30 分钟。在不成对的暴露过程中，饮酒期结束后，大鼠要么留在自己的笼子里（实验 1），要么被限制在新的小房间中 30 分钟，以控制处理和仅仅暴露于新环境（实验 2）。在这些训练试验之后，在这两个实验中，大鼠都对两种溶液进行了 5 小时的偏好测试。尽管在这两个实验的训练过程中都没有 CTA 的证据，但 CTA 在两个实验的双瓶偏好测试中都很明显。
Abstract Wheel running has been shown to induce conditioned taste aversion (CTA). The present experiments tested whether activity in a flat, circular alley also induces CTA. In each of two experiments, one group of rats received paired exposures to one flavored solution and unpaired exposures to a second flavored solution and vice versa for a second group. During a paired exposure, the rats were given access to a flavored solution for 10 min and then confined in an alley for 30 min. During an unpaired exposure, after the drinking period ended, the rats either remained in their home cages (Experiment 1) or were confined in small, novel chambers for 30 min to control for handling and mere exposure to a novel environment (Experiment 2). After these training trials, in both experiments, the rats were given a 5-h preference test with the two solutions. Although there was no evidence of CTA during training in either experiment, CTA was evident in the two-bottle preference test in both.
