规划是认知的重要组成部分，例如有助于在空间中有效移动。在当前的研究中，我们向四只黑猩猩和三只卷尾猴展示了新颖的二维小巷迷宫，以识别与不同任务参数相关的规划的性质和效率。所有受试者都没有错误地解决了比偶然预期更多的迷宫，这提供了令人信服的证据，表明两个物种都以某种方式计划了他们的选择。在设计要求更高并在测试系列中稍后呈现的迷宫中做出正确选择的概率高于早期、简单的迷宫（黑猩猩）或未改变的迷宫（卷尾猴），这表明策略选择的微观发展。迷宫的结构特性影响了两个物种的选择。与黑猩猩相比，卷尾猴不太可能采取最初偏离目标但最终到达目标的正确路径。黑猩猩通过正确的道路比转向错误的道路更有可能犯错误。黑猩猩和一只卷尾猴在离球门越远的选择上犯的错误就越多。在大约 40% 的情况下，每个物种都会在跑到小巷尽头之前纠正错误。总之，这些发现表明每个物种都具有新生的规划能力，以及在呈现多个同时或顺序空间关系的任务上显着发展战略规划能力的前景。计算机迷宫范式似乎非常适合研究人类和非人类灵长类动物的运动规划和空间感知。
Planning is an important component of cognition that contributes, for example, to efficient movement through space. In the current study we presented novel two-dimensional alley mazes to four chimpanzees and three capuchin monkeys to identify the nature and efficiency of planning in relation to varying task parameters. All the subjects solved more mazes without error than expected by chance, providing compelling evidence that both species planned their choices in some manner. The probability of making a correct choice on mazes designed to be more demanding and presented later in the testing series was higher than on earlier, simpler mazes (chimpanzees), or unchanged (capuchin monkeys), suggesting microdevelopment of strategic choice. Structural properties of the mazes affected both species' choices. Capuchin monkeys were less likely than chimpanzees to take a correct path that initially led away from the goal but that eventually led to the goal. Chimpanzees were more likely to make an error by passing a correct path than by turning onto a wrong path. Chimpanzees and one capuchin made more errors on choices farther in sequence from the goal. Each species corrected errors before running into the end of an alley in approximately 40% of cases. Together, these findings suggest nascent planning abilities in each species, and the prospect for significant development of strategic planning capabilities on tasks presenting multiple simultaneous or sequential spatial relations. The computerized maze paradigm appears well suited to investigate movement planning and spatial perception in human and nonhuman primates alike.
