The influence of non-reinforced exposure to compound stimuli on subsequent appetitive classical conditioning was examined in five experiments with rats as the subjects. Non-reinforced exposure to a visual stimulus retarded subsequent acquisition of conditioned responding relative to a non-pre-exposed condition (latent inhibition). If the target stimulus was pre-exposed in compound with a second (non-target) stimulus, then latent inhibition was abolished. Exposure to the non-target stimulus prior to compound exposure had varying effects on subsequent conditioning to the target: 40 exposures to the non-target stimulus resulted in latent inhibition to the target stimulus that was comparable in magnitude to that observed when the target stimulus was exposed in isolation; 120 exposures to the non-target stimulus enhanced latent inhibition to the target stimulus.
在五项以大鼠为实验对象的实验中，研究了非强化暴露于复合刺激对随后的食欲性经典条件作用的影响。相对于未预先暴露的条件（潜伏抑制），非强化暴露于视觉刺激会延迟随后条件反应的习得。如果目标刺激与第二个（非目标）刺激复合预先暴露，那么潜伏抑制就会消除。在复合暴露之前暴露于非目标刺激对随后对目标的条件作用有不同影响：对非目标刺激进行40次暴露会导致对目标刺激的潜伏抑制，其程度与单独暴露目标刺激时观察到的相当；对非目标刺激进行120次暴露会增强对目标刺激的潜伏抑制。
