摘要

阻滞现象是学习研究中最持久的问题之一。人们提出了许多解释,主要分为两类。联想分析表明,在A+/AX+训练之后,线索A阻止了X和结果之间形成联想联系。相反,推论解释是,A+/AX+训练不允许推断X导致结果。更具体地说,提出X的试验(AX+)通常被认为对X的因果状态没有提供信息,因为无论X是否为因果,结果都会导致AX试验的结果。如果参与者对X不确定,他们在测试中的评分可能对结果的总体基本率特别敏感。也就是说,当大多数线索导致结果时,与大多数线索没有导致结果时相比,一个不确定的受阻线索应该被评为更可能的原因。这一假设得到了2个实验的支持。实验1使用遮蔽控制,实验2使用不相关控制(以证明冗余效应)。如果参与者不确定被阻止的线索的状态,则可以解释由于操纵结果基准率而导致的被阻止线索评级的变化。实验3表明,通过使用直接的自我报告测量确定性,参与者对被屏蔽的线索不确定。这些数据与推理解释一致,但对关联分析更具挑战性。(PsycINFO数据库记录(c) 2019 APA,版权所有)。

Uncertainty and blocking in human causal learning.

The blocking phenomenon is one of the most enduring issues in the study of learning. Numerous explanations have been proposed, which fall into two main categories. An associative analysis states that, following A+/AX+ training, Cue A prevents an associative link from forming between X and the outcome. In contrast, an inferential explanation is that A+/AX+ training does not permit an inference that X causes the outcome. More specifically, the trials on which X is presented (AX+) are often argued to be uninformative with respect to the causal status of X because the outcome would have resulted on AX trials whether X was causal or not. If participants are uncertain about X, their ratings on test might be particularly sensitive to the overall base rate of the outcome. That is, a blocked cue, about which one is uncertain, should be rated as a more likely cause when most cues lead to the outcome than when most cues do not. This hypothesis was supported in 2 experiments. Experiment 1 used an overshadowing control and Experiment 2 used an uncorrelated control (to demonstrate a redundancy effect). Variations in the ratings of the blocked cue as a result of manipulating the outcome base rate can be explained if participants are uncertain about the status of the blocked cue. Experiment 3 showed that participants are uncertain about blocked cues by using a direct self-report measure of certainty. These data are consistent with the inferential account, but are more challenging for the associative analysis. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
