在第一个实验中，一组大鼠（组学习无关[LIRR]）经历了不相关的噪音和休克的表现;第二组（组控制[CON]）在不同的训练阶段经历了噪音和休克。随后进行了六次条件反射训练，每次训练由一个单独的噪声-电击配对组成。LIRR组比CON组更快地适应于噪声。第二个实验与第一个实验相同，不同之处在于每个条件化阶段给予6个噪声-电击配对。在这个实验中，LIRR组学习速度比CON组慢。这些结果表明，学习无关性的一部分是产品的背景特异性的潜在抑制，其中的背景是休克介绍的后效。这对学习无关理论的影响进行了讨论。
In the Ist experiment, 1 group of rats (Group Learned Irrelevance [LIRR]) experienced uncorrelated presentations of a noise and shock; a 2nd group (Group Control [CON]) experienced noise and shock in separate phases of training. Six conditioning sessions followed, each consisting of a single noise-shock pairing. Group LIRR conditioned to the noise more quickly than Group CON. The 2nd experiment was identical to the Ist, except that rats were given 6 noise-shock pairings in each conditioning session. In this experiment, Group LIRR learned more slowly than Group CON. These results suggest that learned irrelevance is in part the product of context specificity of latent inhibition, in which the context is the aftereffect of shock presentation. The implications of this for theories of learned irrelevance are discussed.
