Latent inhibition, retarded learning after pre-exposure to the to-be-conditioned stimulus, was examined using a blink conditioned procedure in humans. Experiment 1 showed that the procedure is suited to inducing the latent inhibition effect. In Experiment 2, the introduction of a 3-minute interval between pre-exposure and conditioning phases attenuated latent inhibition. These results contribute to identify the mechanisms involved in pre-exposure and subsequent conditioning of a stimulus, which is particularly important if we bear in mind that latent inhibition has been used repeatedly as an instrument to analyze the course of attentional processes in normal and pathological populations.
潜伏抑制，即预先暴露于要条件刺激后学习能力的下降，在人类的眨眼条件反射程序中得到了检验。实验 1 表明，该程序适合诱导潜伏抑制效应。在实验 2 中，在预暴露和条件作用阶段之间引入 3 分钟的间隔会减弱潜伏抑制。这些结果有助于确定在刺激的预暴露和随后的条件作用中涉及的机制，这一点非常重要，如果我们考虑到潜伏抑制已经被反复用作分析正常和病理人群注意力过程的一种手段的话。
