反复受到干扰需要集中注意力来恢复任务表现。然而，反复接触干扰物和集中注意力对新学习的影响尚未得到检验。在本实验中，老鼠接受了两杆持续注意力任务的训练。然后，大鼠继续训练 12 次，在整个训练期间有或没有闪烁的室内灯光干扰物。闪烁的室内灯光会暂时降低注意力。作为新的光位置辨别任务一部分的试验随后散布在持续注意力任务会议中。这些新的光位置辨别试验的频率随着额外的训练而增加。与未暴露于干扰物的大鼠相比，暴露于干扰物的大鼠在新的光位置辨别任务试验和剩余的持续注意力任务试验的某些会话期间表现出更高的准确度水平。重复暴露干扰物的影响是在“场合设置”模型的背景下解释的，该模型已用于描述该任务的表现。
Repeated exposure to distraction requires attentional effort to restore task performance. However, the impact of repeated distracter exposure and exertion of attentional effort on new learning has not been examined. In the present experiment, rats were trained in a two-lever sustained attention task. Rats then continued to train, for 12 sessions, in this task either with or without a flashing houselight distracter throughout the session. The flashing houselight transiently decreased attentional performance. Trials that were part of a new light-location discrimination task were then interspersed within the sustained attention task sessions. The frequency of these new light-location discrimination trials increased with additional training. Rats exposed to the distracter exhibited higher accuracy levels during some blocks of sessions in the new light-location discrimination task trials and in the remaining sustained attention task trials compared to rats that were not exposed to the distracter. The effects of repeated distracter exposure are interpreted in the context of an “occasion-setting” model that has been used to describe performance in this task.
