歧视逆转学习已被用来作为一个衡量物种的灵活性，在处理强化应急的变化。在错误辨别、会话中期反转任务中，一个刺激（S1）对于会话的前半部分是正确的，另一个刺激（S2）对于会话的后半部分是正确的。经过训练，鸽子表现出一种奇怪的选择模式。他们开始在反转点之前就对S2做出反应（他们犯预期错误），在反转点之后继续对S1做出反应（他们犯持续错误）。也就是说，他们似乎正在利用会话中的时间流逝或尝试次数作为逆转的线索，并且对逆转点的反馈不太敏感。为了确定在前一次试验中选择的刺激的辨别性质或记忆失败是否导致鸽子的表现低于最佳表现，我们操纵了辨别的性质（空间或视觉）和试验间隔的持续时间（5.0或1.5秒），以确定在什么条件下鸽子会表现出有效的反向学习。主要的发现是，只有当歧视是空间和审判间隔很短的鸽子表现最佳。
Discrimination reversal learning has been used as a measure of species flexibility in dealing with changes in reinforcement contingency. In the simultaneous-discrimination, midsession reversal task, one stimulus (S1) is correct for the first half of the session and the other stimulus (S2) is correct for the second half. After training, pigeons show a curious pattern of choices. They begin to respond to S2 well before the reversal point (they make anticipatory errors) and they continue to respond to S1 well after the reversal (they make perseverative errors). That is, they appear to be using the passage of time or number of trials into the session as a cue to reverse and are less sensitive to the feedback at point of reversal. To determine if the nature of the discrimination or a failure of memory for the stimulus chosen on the preceding trial contributed to the pigeons’ less than optimal performance, we manipulated the nature of the discrimination (spatial or visual) and the duration of the intertrial interval (5.0 or 1.5 s) to determine under what conditions pigeons would show efficient reversal learning. The major finding was that only when the discrimination was spatial and the intertrial interval was short did the pigeons perform optimally.
