In 4 conditioned lick suppression experiments with rats, the combined effects of latent inhibition treatment followed by overshadowing treatment were assessed as a test of the comparator hypothesis's (R.R. Miller & L.D. Matzel, 1988) explanations of overshadowing and latent inhibition. Experiments 1 and 2 confirmed the prediction of the comparator hypothesis that combined latent inhibition and overshadowing treatments attenuate the response deficit produced by either treatment alone. Furthermore, consistent with the comparator hypothesis, posttraining changes in the associative status of the putative comparator stimulus altered responding to the target conditioned stimulus (Experiment 3), and switching contexts between latent inhibition and overshadowing treatments (Experiment 4) eliminated the interaction between the latent inhibition and overshadowing treatments.
在对大鼠进行的4项条件性舔舐抑制实验中，评估了先进行潜伏抑制处理再进行遮蔽处理的联合效应，以此作为对比较器假说（R.R. 米勒和L.D. 马策尔，1988年）对遮蔽和潜伏抑制解释的一种检验。实验1和实验2证实了比较器假说的预测，即潜伏抑制和遮蔽处理相结合会减弱单独一种处理所产生的反应缺陷。此外，与比较器假说一致，假定比较器刺激的联想状态在训练后的变化改变了对目标条件刺激的反应（实验3），并且在潜伏抑制和遮蔽处理之间切换情境（实验4）消除了潜伏抑制和遮蔽处理之间的相互作用。
