学习一个线索（CS）预测第二个，显着的线索（US），往往可以通过先前暴露于一个或两个刺激放缓。在动物中，CS-US学习在暴露于CS和US两者不相关之后比单独暴露于US之后更强烈地延迟。在本文中，我们提出了几项研究，显示了类似的效果，在人类中，使用基于计算机的任务。实验1和2使用组间设计，并表现出强烈的CS/US曝光效果，无论美国是由一个中性的线索在曝光过程中发出信号。实验3使用受试者内设计证明了类似的效果。总的来说，这些结果与几种理论解释一致，并表明不相关的CS/US暴露导致人类后续CS-US学习的强烈阻滞。
Learning that one cue (CS) predicts a second, salient cue (US) can often be slowed by prior exposure to one or both stimuli. In animals, CS-US learning is more strongly retarded following uncorrelated exposure to both CS and US than following exposure to the US alone. In this paper we present several studies showing a similar effect in humans, using a computer-based task. Experiments 1 and 2 used a between-groups design and demonstrated a strong CS/US exposure effect, whether or not the US was signalled by a neutral cue during exposure. Experiment 3 demonstrated similar effects using a within-subjects design. Overall, these results are consistent with several theoretical interpretations and suggest that uncorrelated CS/US exposure leads to a robust retardation of subsequent CS-US learning in humans.
