Two monkeys (Macaca mulatta) learned a color change-detection task where two colored circles (selected from a 4-color set) were presented on a 4 × 4 invisible matrix. Following a delay, the correct response was to touch the changed colored circle. The monkeys' learning, color transfer, and delay transfer were compared to a similar experiment with pigeons. Monkeys, like pigeons (Columba livia), showed full transfer to four novel colors, and to delays as long as 6.4 s, suggesting they remembered the colors as opposed to perceptual based attentional capture process that may work at very short delays. The monkeys and pigeons were further tested to compare transfer with other dimensions. Monkeys transferred to shape and location changes, unlike the pigeons, but neither species transferred to size changes. Thus, monkeys were less restricted in their domain to detect change than pigeons, but both species learned the basic task and appear suitable for comparative studies of visual short-term memory.
两只恒河猴学会了一项颜色变化检测任务，在一个4×4的不可见矩阵上会呈现两个彩色圆圈（从四种颜色的集合中选取）。经过一段时间延迟后，正确的反应是触摸颜色发生变化的圆圈。将猴子的学习、颜色迁移和延迟迁移情况与一项针对鸽子的类似实验进行了比较。与鸽子（家鸽）一样，猴子能够完全迁移到四种新颜色，并且能够迁移到长达6.4秒的延迟情况，这表明它们记住了颜色，而不是基于感知的注意力捕获过程，后者可能只在非常短的延迟情况下起作用。对猴子和鸽子进行了进一步测试，以比较它们在其他维度上的迁移情况。与鸽子不同，猴子能够迁移到形状和位置变化，但两种动物都不能迁移到大小变化。因此，猴子在检测变化的领域限制比鸽子少，但两种动物都学会了基本任务，似乎都适合用于视觉短期记忆的比较研究。
