计划是一个人制定未来行为的有组织方法的内在过程，它对人类和非人类动物都是有利的。然而，对鸟类物种的这一过程知之甚少。我们研究规划过程中的鸽子（鸽）使用计算机迷宫任务。在实验1中，我们发现鸽子计划他们的下一个步骤，在某些情况下，甚至正确地调整他们的行动后，改变目标位置，而执行一个加号形迷宫。我们还发现，鸽子甚至可能在熟悉的、熟练的迷宫上计划两步。在实验2中，我们发现受试者在开始解决四臂shuriken（日本传统飞刀）形状的迷宫之前计划他们首先要走的方向。在改变目标位置后，这些鸟也纠正了它们先前计划的行动。我们从这些实验中得到的结果表明，提前计划是在“鸟脑”的认知能力范围内的，而且它在动物王国中的分布可能比我们想象的要广泛。
Planning, the internal process of formulating an organized method about one's future behavior, should be advantageous for non-human animals as well as for humans. However, little is known about this process in avian species. We examined planning processes in pigeons (Columba livia) using a computerized maze task. In Experiment 1, we found that the pigeons plan their next one step, and in some cases even correctly adjust their actions after change of goal locations, while performing on a plus-shaped maze. We also showed that the pigeons might even plan two steps on familiar, well-practiced mazes. In Experiment 2, we discovered that the subjects plan the direction they would go first before starting to solve a four-arm shuriken (a Japanese traditional throwing knife)-shaped maze. The birds also corrected their previously planned actions after change of goal locations. Our results from these experiments suggest that planning ahead is within the cognitive capacity of a "bird brain", and that it may be more widespread in the animal kingdom than has been presumed.
