重复配对的特定视觉环境与特定位置的目标刺激促进目标搜索在人类。我们探索了一个动物模型，这种背景线索。小猪必须啄一个目标，这个目标可能出现在现实世界场景的彩色照片上的4个位置之一。在一半的试验中，4个场景中的每一个都与4个可能的目标位置中的1个一致配对;在另一半的试验中，4个不同场景中的每一个都与相同的4个可能的目标位置随机配对。在实验1和2中，鸽子表现出强大的上下文线索时，上下文之前的目标由1秒至8秒，与反应时间的目标是短预测场景试验比随机场景试验。在预测场景试验的延迟期间，鸽子也比随机场景试验更频繁地做出反应;事实上，在预测场景试验的延迟期间，鸽子主要向即将到来的目标的位置啄，这表明注意力引导有助于上下文提示。在实验3中，涉及左右和上下场景反转，鸽子表现出更强的控制全球比本地场景线索。这些结果证明了鸽子上下文线索的鲁棒性和关联性基础。（PsycInfo数据库记录（c）2016阿帕，保留所有权利）
Repeated pairings of a particular visual context with a specific location of a target stimulus facilitate target search in humans. We explored an animal model of such contextual cueing. Pigeons had to peck a target, which could appear in 1 of 4 locations on color photographs of real-world scenes. On half of the trials, each of 4 scenes was consistently paired with 1 of 4 possible target locations; on the other half of the trials, each of 4 different scenes was randomly paired with the same 4 possible target locations. In Experiments 1 and 2, pigeons exhibited robust contextual cueing when the context preceded the target by 1 s to 8 s, with reaction times to the target being shorter on predictive-scene trials than on random-scene trials. Pigeons also responded more frequently during the delay on predictive-scene trials than on random-scene trials; indeed, during the delay on predictive-scene trials, pigeons predominately pecked toward the location of the upcoming target, suggesting that attentional guidance contributes to contextual cueing. In Experiment 3, involving left–right and top–bottom scene reversals, pigeons exhibited stronger control by global than by local scene cues. These results attest to the robustness and associative basis of contextual cueing in pigeons.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
