The present experiments studied the role of error correction mechanisms in the latent inhibition of conditioned fear responses by conditioned stimulus (CS) preexposure. They demonstrated that a preexposed CS subjected to additional exposures in compound with either another preexposed stimulus or a novel stimulus was more latently inhibited than a preexposed CS which received additional exposures in isolation. They also showed that a preexposed CS subjected to additional exposures in compound with another preexposed stimulus was more latently inhibited than a preexposed CS given additional exposures in compound with a novel stimulus. These results were discussed in terms of the Hall-Rodriguez (2010) model of latent inhibition.
本实验研究了错误校正机制在条件刺激（CS）预暴露对条件性恐惧反应的潜伏抑制中的作用。实验表明，与另一个预暴露刺激或新刺激复合进行额外暴露的预暴露CS，比单独进行额外暴露的预暴露CS受到更强的潜伏抑制。实验还表明，与另一个预暴露刺激复合进行额外暴露的预暴露CS，比与新刺激复合进行额外暴露的预暴露CS受到更强的潜伏抑制。根据霍尔 - 罗德里格斯（2010年）的潜伏抑制模型对这些结果进行了讨论。
