In one human predictive learning experiment, we demonstrated that an individual's propensity for response recovery following discrimination reversal learning is stable over time. Participants received four sessions of training with the first three sessions being separated by one week each, while the last session was conducted after a delay of four weeks. During each session, participants initially received discrimination training (E+, F-) in one context, followed by discrimination reversal training (E-, F+) in another context. Sessions each completed with a test, in which the stimuli were presented in the context of initial acquisition. Each test revealed response recovery according to the initially acquired stimulus-outcome contingencies. Furthermore, the strength of response recovery was correlated across sessions that were separated by one week (Sessions 1 and 2), and across sessions separated by four weeks (Sessions 3 and 4). Overall, intra-individual test behavior was stable in 87% of participants across two sessions, and in 79% of participants across four sessions. Our results indicate that inter-individual differences in response recovery are a reliable phenomenon, which is a finding that is not accounted by current theories of context-dependent learning.

判别逆转学习后反应恢复的重测信度

在一项人类预测学习实验中，我们证明了个体在歧视逆转学习后恢复反应的倾向随着时间的推移是稳定的。参与者接受了四节培训，前三节每节相隔一周，而最后一节是在延迟四个星期后进行的。在每次会议期间，参与者最初在一种情况下接受歧视训练（E+、F-），然后在另一种情况下接受歧视逆转训练（E-、F+）。每个会话都通过测试完成，其中在初始采集的背景下呈现刺激。根据最初获得的刺激结果意外事件，每个测试都显示了反应恢复。此外，反应恢复的强度在相隔一周的课程（课程 1 和 2）和相隔 4 周的课程（课程 3 和 4）之间相关。总体而言，在两次会话中，87% 的参与者和四次会话中 79% 的参与者的个体内测试行为是稳定的。我们的结果表明，反应恢复的个体差异是一种可靠的现象，这一发现并未被当前的情境相关学习理论所解释。
