最近的研究表明，结果加和性预训练调节人类因果学习中的阻滞。然而，现有的证据混淆了结果的可加性和结果的最大化。在这里，作者提出证据的影响，呈现信息的结果最大化（实验1）和结果的加性（实验2）对随后的前向阻滞。实验3的结果证实，与结果最大化控制，结果加性影响后向阻塞，但不释放遮蔽。最后，实验4的结果表明，结果加和性的信息具有类似的效果，前向阻塞，如果在阻塞训练后，而不是之前。结果是兼容的想法，即阻塞的结果从推理过程中的测试，而不是从失败，以获得联想强度在训练过程中。
Recent research suggests that outcome additivity pretraining modulates blocking in human causal learning. However, the existing evidence confounds outcome additivity and outcome maximality. Here the authors present evidence for the influence of presenting information about outcome maximality (Experiment 1) and outcome additivity (Experiment 2) on subsequent forward blocking. The results of Experiment 3 confirm that, with outcome maximality controlled, outcome additivity affects backward blocking but not release from overshadowing. Finally, the results of Experiment 4 demonstrate that information about outcome additivity has a similar effect on forward blocking if presented after the blocking training instead of before. The results are compatible with the idea that blocking results from inferential processes at the time of testing and not from a failure to acquire associative strength during training.
