The effects of stimulus controllability on latent inhibition was examined in instrumental and classical conditioning. Rats allowed control over stimulus termination prior to avoidance conditioning exhibited no retardation of avoidance learning whereas subjects yoked to these rats with respect to pattern and amount of stimulus exposure but given no control over stimulus termination were retarded. However, groups of rats differentiated only by control over stimulus termination, prior to classical conditioning, were equally and severely retarded in the acquisition of a classically conditioned response as indexed by the CER technique. The results were discussed in terms of a learning hypothesis of latent inhibition.
在工具性条件反射和经典性条件反射中，研究了刺激可控性对潜伏抑制的影响。在回避条件反射之前能够控制刺激终止的大鼠，其回避学习没有延迟，而在刺激呈现的模式和量方面与这些大鼠匹配但无法控制刺激终止的受试大鼠则出现了学习延迟。然而，在经典性条件反射之前，仅在刺激终止控制方面存在差异的几组大鼠，在通过条件性情绪反应（CER）技术测定的经典性条件反射反应的习得过程中，均同样严重地出现了延迟。根据潜伏抑制的学习假说对这些结果进行了讨论。
