Abstract
Four rats were trained on a schedule in which completion of a fixed number of lever presses initiated a signalled delay period, at the end of which food was delivered. Lever presses made during the delay had no scheduled consequences. Delays of 12, 3, and 0.75 sec were used, and it was found that the latency of the first response after food (the post-reinforcement pause) increased with length of delay. There was, on the other hand, no consistent effect of delay upon rates of responding after the post-reinforcement pause.
摘要
四只老鼠接受了一项训练，即在按下一定数量的杠杆后，会开始一个有信号的延迟期，在此期间会给予食物。在延迟期间按下杠杆没有预定的结果。使用了 12、3 和 0.75 秒的延迟，结果发现，食物后的第一次反应（强化后停顿）的潜伏期随着延迟时间的增加而增加。另一方面，在强化后停顿后，延迟对反应率没有一致的影响。
