Voluntary wheel running works as an effective unconditioned stimulus (US) to establish conditioned taste aversion (CTA) in rats with a preceding taste solution as a conditioned stimulus (CS): repeated CS-US pairings evoke avoidance of the CS in the two-choice (CS vs. tap water) test administered at the end of the training. Experiment 1 demonstrated that exposure to running immediately before each CS-US trial alleviates CTA. Subsequent two experiments explored the characteristics of the proximal US-preexposure effect: the alleviation of CTA by the pretrial running was not affected by changing the background contexts between the pretrial and the trial running (Experiment 2) or by signaling the pretrial running via another taste cue (Experiment 3). These results indicate the robustness of the proximal US-preexposure effect and fit well with the predictions of Wagner's (1976, 1978) priming theory.

审前跑步对大鼠基于跑步的口味厌恶学习的影响。

自愿滚轮运动是一种有效的无条件刺激（美国），可在先有味觉溶液作为有条件刺激（CS）的大鼠中建立有条件的味觉厌恶（CTA）：重复的CS-US配对可避免在两种选择中使用CS在训练结束时进行（CS vs.自来水）测试。实验1证明，在每次CS-US试验之前，立即进行跑步训练都可以缓解CTA。随后的两个实验探讨了近端US暴露前效应的特征：通过改变审前和试验运行之间的背景环境（通过实验2）或通过通过其他口味发出信号来告知审前运行，未影响审前运行对CTA的缓解。提示（实验3）。这些结果表明了近端US暴露效应的鲁棒性，并且与Wagner（1976，1978）启动理论的预测非常吻合。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
