In two experiments, observer rats saw a pretrained demonstrator rat of either the same or a different strain engaging in a discrimination task in which the presentation of a discriminative stimulus indicated whether performing a particular response (pulling a chain) would be reinforced. In both experiments an effect of demonstrator familiarity was found: Observers of a demonstrator from a different strain behaved in a manner that was consistent with the demonstrator whereas observers of a demonstrator from the same strain did not. These results suggest that an effect akin to latent inhibition operates in the social domain: Familiarity with the demonstrator retards the readiness with which observational learning proceeds.
在两项实验中，作为观察者的大鼠看到一只经过预训练的示范大鼠（与观察者为同一品系或不同品系）参与一项辨别任务，在该任务中，辨别刺激的呈现表明执行特定反应（拉链条）是否会得到强化。在两项实验中均发现了示范者熟悉度的影响：来自不同品系的示范者的观察者的行为与示范者一致，而来自同一品系的示范者的观察者则不然。这些结果表明，一种类似于潜伏抑制的效应在社会领域起作用：对示范者的熟悉会阻碍观察性学习的进行。
