Pigeons acquired a successive depayed matching-to-sample task at delay intervals ranging from 2.5 to 7 seconds. Test sessions were conducted during which delay-interval illumination conditions were changed from those illumination conditions that prevailed during the baselines. Compared to baseline delayed matching performance, changing delay-interval illumination disrupted matching. This disruption occurred whether the change in delay-interval illumination represented an increase or a decrease, relative to the baseline, and whether there was or was not a change in illumination during the test session. It was concluded that illumination per se introduced during delay intervals of delayed matching tasks does not interfere with pigeon short-term memory. Rather, a change in delay-interval illumination, relative to the baseline, appears to retroactively interfere in pigeon short-term memory.
鸽子在2.5秒至7秒的延迟间隔内完成了一项连续延迟的样本匹配任务。进行了测试环节，在此期间延迟间隔照明条件与基线期间盛行的照明条件有所不同。与基线延迟匹配表现相比，改变延迟间隔照明会干扰匹配。无论延迟间隔照明的变化相对于基线是增加还是减少，以及测试环节中照明是否发生变化，这种干扰都会出现。研究得出结论，在延迟匹配任务的延迟间隔期间引入的照明本身不会干扰鸽子的短期记忆。相反，相对于基线而言，延迟间隔照明的变化似乎会追溯性地干扰鸽子的短期记忆。
