在两个实验中，独立组的鸽子进行了培训的身份匹配任务，涉及线的方向作为样本和比较刺激。对于一些鸽子来说，头顶上的室内灯在每次训练中都是持续照明的。对于其他鸟类来说，在训练期间，室内的灯光从来没有亮过。在随后的测试中，在延迟期间的照明条件是相同的，在一些试验中的训练，但在其他试验中，他们是相反的，无论是在整个延迟（实验1）或在延迟的一部分（实验2）的培训。在室内灯关闭的情况下训练的鸟类中，在延迟期间打开室内灯对匹配准确性产生了巨大而持久的干扰。另一方面，在训练的鸟类与houselight上，把houselight关闭在延迟期间只产生了适度的和暂时的中断匹配的准确性。这些研究结果是不一致的流行观点，追溯干扰鸽子是一个功能的变化，在照明水平相对于，在培训期间盛行。在鸽子中，就像在猴子中一样，只有在延迟间隔期间增加照明水平时，才能获得持续的反射干扰效应。
In two experiments, independent groups of pigeons were trained on an identity matching task involving line orientations as sample and comparison stimuli. For some birds an overhead houselight was illuminated continuously throughout each training session. For other birds the houselight was never illuminated during training sessions. During subsequent testing, the lighting conditions during the delay were the same as in training on some trials, but on other trials they were opposite those of training during either the entire delay (Experiment 1) or during a portion of the delay (Experiment 2). In birds trained with the houselight off, turning the houselight on during the delay produced a large and enduring disruption in matching accuracy. On the other hand, in birds trained with the houselight on, turning the houselight off during the delay produced only a moderate and temporary disruption in matching accuracy. These findings are inconsistent with the prevailing view that retroactive interference in pigeons is a function of a change in illumination level relative to that which prevailed during training. In pigeons, as in monkeys, sustained retoactive interference effects obtain only when the level of illumination is increase during the delay interval.
