In Pavlovian fear conditioning, context-mediated decrements in conditioned responding (e.g., the US preexposure effect) can counteract competition between cues trained together (e.g., overshadowing). Two experiments were conducted using rats in a conditioned lick suppression preparation to determine whether context-mediated competition also counteracts competition between c ues trained separately (retroactive interference, or RI). In Experiment 1, a combination of degraded contingency and RI treatments produced less of a decrement in conditioned responding than did either of those treatments alone. Experiment 2 showed that RI treatment attenuates the normally deleterious effect of trial massing. The results suggest that empirical similarities are shared by interference between cues trained apart and competition between cues trained together.
在巴甫洛夫式恐惧条件反射中，由情境介导的条件反应的减少（例如，非条件刺激预暴露效应）可以抵消共同训练的线索之间的竞争（例如，遮蔽）。进行了两项实验，使用大鼠进行条件性舔舐抑制实验，以确定情境介导的竞争是否也能抵消单独训练的线索之间的竞争（ retroactive interference，或RI）。在实验1中，与单独使用这两种处理方法相比，退化性偶联和RI处理的组合导致条件反应的减少幅度更小。实验2表明，RI处理减弱了试验集中通常产生的有害影响。结果表明，单独训练的线索之间的干扰与共同训练的线索之间的竞争具有经验上的相似性。
