Voluntary running in an activity wheel endowed rats with aversion to a taste solution consumed before the running. This running-based taste aversion was attenuated by extra running opportunities interspersed among the taste-running pairings, but the attenuating effect was reduced by signaling the extra running by another taste cue. These results correspond to the so-called degraded contingency effect and cover-cue effect in the traditional preparations of Pavlovian conditioning.
在活动轮中自愿跑步使大鼠对跑步前饮用的味觉溶液产生厌恶。这种基于跑步的味觉厌恶会因在味觉与跑步配对过程中穿插额外的跑步机会而减弱，但通过另一种味觉线索来提示额外的跑步会降低这种减弱效果。这些结果与经典条件作用传统实验中的所谓退化性条件作用效应和掩盖线索效应相对应。
