一个受试者内的比较，鸽子的表现上的两个时间的歧视程序，信号不同颜色的按键样本。在刺激试验期间，在短按键样本之后，在显示斜线的键上的啄被加强，并且在长按键样本之后，在显示水平线的键上的啄被加强，而不管在这两个选择键上的刺激的位置。在位置试验期间，在短的按键样本之后，在左按键上的啄被加强，在长的按键样本之后，在右按键上的啄被加强，而不管在正确的按键上出现哪条线刺激。因此，在刺激试验中，在呈现测试刺激之前不能辨别正确的选择键，而在位置试验中，在呈现样本刺激期间可以辨别正确的选择键。在第1阶段，样品和选择刺激之间的0秒延迟，歧视学习是更快的位置试验比刺激试验的所有4只鸟。在第2阶段，0，0.5，和1.0秒的延迟产生差异损失的刺激控制下的两个任务2只鸟。延迟间隔期间的反应模式提供了一些证据，两个延迟歧视的差异调解。这些任务之间的差异表明，相同的过程可能不会调解每个性能。
A within-subjects comparison was made of pigeons' performance on two temporal discrimination procedures that were signaled by differently colored keylight samples. During stimulus trials, a peck on the key displaying a slanted line was reinforced following short keylight samples, and a peck on the key displaying a horizontal line was reinforced following long keylight samples, regardless of the location of the stimuli on those two choice keys. During position trials, a peck on the left key was reinforced following short keylight samples and a peck on the right key was reinforced following long keylight samples, regardless of which line stimulus appeared on the correct key. Thus, on stimulus trials, the correct choice key could not be discriminated prior to the presentation of the test stimuli, whereas on position trials, the correct choice key could be discriminated during the presentation of the sample stimulus. During Phase 1, with a 0-s delay between sample and choice stimuli, discrimination learning was faster on position trials than on stimulus trials for all 4 birds. During Phase 2, 0-, 0.5-, and 1.0-s delays produced differential loss of stimulus control under the two tasks for 2 birds. Response patterns during the delay intervals provided some evidence for differential mediation of the two delayed discriminations. These between-task differences suggest that the same processes may not mediate performance in each.
