先前的研究表明，当一个固定间隔被中断（被称为间隔程序）时，鸽子往往会重置记忆，并在间隔之后从0开始计时。然而，由于间隔的环境条件通常与试次间隔（ITI）期间相同，可能会产生模糊性。在当前的实验中，作者发现当间隔期间的环境条件与记忆条件（M）相似时，鸽子往往会重置记忆，但当间隔期间的环境条件与试次间隔不同时，鸽子往往会停止计时，将刺激的持续时间保留在记忆中，并在刺激再次出现时将其累加。因此，当间隔明确时，鸽子计时准确。
Previous research suggests that when a fixed interval is interrupted (known as the gap procedure), pigeons tend to reset memory and start timing from 0 after the gap. However, because the ambient conditions of the gap typically have been the same as during the intertrial interval (ITI), ambiguity may have resulted. In the present experiment, the authors found that when ambient conditions during the gap were similar to the M, pigeons tended to reset memory, but when ambient conditions during the gap were different from the ITI, pigeons tended to stop timing, retain the duration of the. stimulus in memory, and add to that time when the stimulus reappeared. Thus, when the gap was unambiguous, pigeons timed accurately.
