Pigeons learned to peck the left or right of two white keys depending on whether a red or a green stimulus was displayed on a third key. The opportunity to peck the white keys was then dealyed for zero to six seconds after the red or green (to-be-remembered) stimulus. On half the trials, the feeder operated during the delay to interrupt behavior that might mediate discriminated responding. No events were scheduled on the remaining trials. In a later condition, the pigeons had the opportunity to peck the white keys during the delay. In general, accuracy decreased as delay increased in all conditions, but performance was least accurate following feeder operations and most accurate when pecking was allowed during the delay. The procedures may be analogous to varying the opportunity for rehearsal in studies of human short-term memory.
鸽子学会根据第三个按键上显示的是红色还是绿色刺激，来啄两个白色按键中的左边或右边。在红色或绿色（需记忆的）刺激出现后，啄白色按键的机会随后被延迟零至六秒。在一半的试验中，喂食器在延迟期间运作，以打断可能介导辨别性反应的行为。其余试验则未安排任何事件。在随后的一个条件下，鸽子在延迟期间有机会啄白色按键。总体而言，在所有条件下，随着延迟增加，准确性都会下降，但在喂食器运作后表现的准确性最低，而在延迟期间允许啄击时准确性最高。这些程序可能类似于在人类短期记忆研究中改变复述的机会。
