在3个人类预测学习实验中，作者考察了辨别反转学习中反应的上下文控制。在阶段1中，在上下文1中训练2个刺激（A+，B-）之间的辨别。在阶段2期间，参与者在情境2中接受辨别逆转训练（A-，B+）。测试发生在上下文1和上下文2（实验1A和1B）或上下文1和上下文3（实验2）中。在测试阶段，上下文1和上下文2中的性能分别反映了在第一阶段和第二阶段训练的意外事件。当在情境3中进行测试时，A和B之间没有区别性反应。此外，实验表明，具有一致强化历史的辨别刺激也受到上下文操纵的影响。结果表明，每个培训环境获得控制性能的能力。独特线索法和图解法是主要的研究方法。
In 3 human predictive learning experiments, the authors examined contextual control of responding in discrimination reversal learning. In Phase 1, a discrimination between 2 stimuli (A+, B-) was trained in Context 1. During Phase 2, participants received discrimination reversal training (A-, B+) in Context 2. Testing occurred in Context 1 and Context 2 (Experiments 1A and 1B) or in Context 1 and Context 3 (Experiment 2). During the test phase, performance in Context 1 and Context 2 reflected the contingencies trained during Phase I and Phase 2, respectively. When testing occurred in Context 3, there was no discriminative responding between A and B. In addition, the experiments demonstrated that discriminating stimuli with a consistent reinforcement history were also affected by contextual manipulations. Results indicate that each training context acquires the ability to control performance. Unique-cue and configural approaches account for a major part of the results.
