采用操作性非匹配样本法比较了3种鸟类的空间记忆能力。试验包括一个空间定义的样本，一个延迟间隔，以及一个正确位置为新位置的二选择测试。在实验1中，单个空间位置作为样本。延迟间隔是通过滴定过程来控制的。在实验2、1、2或3中依次照亮的位置作为样本。延迟是4个预定间隔中的1个。在实验3中，样品呈现与实验2相同，但延迟间隔被滴定。在所有实验中，胡桃鸦的表现始终优于灌丛鸦和鸽子（Exp 1），这与它们觅食生态的差异有关。（PsycINFO数据库记录(c) 2016 APA，版权所有）
An operant nonmatching-to-sample procedure was used to compare the spatial memory abilities of 3 avian species. A trial consisted of the presentation of a spatially defined sample, a delay interval, and a 2-choice test during which the correct location was the new location. A single spatial location served as the sample in Exp 1. The delay interval was manipulated using a titration procedure. In Exp 2, 1, 2, or 3 sequentially illuminated locations served as the sample. The delay was 1 of 4 predetermined intervals. In Exp 3, sample presentation was the same as Exp 2, but the delay interval was titrated. In all of the experiments, the performance of nutcrackers was consistently better than the performance of scrub jays and pigeons (Exp 1) and was correlated with differences in their foraging ecology.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
