支持使用手动工具的感知运动功能可以在其他操作任务中进行检查，例如将物体与表面对齐。我们研究了簇绒卷尾猴和黑猩猩在将物体与表面对齐并同时管理一两个空间关系方面的表现。我们向每个物种的六个受试者展示了一根棍子，将其放入一个凹槽中，将两根等长的棍子放入两个凹槽中，或者将两根棍子连接成 T 形并将其放入 T 形凹槽中。簇绒卷尾猴和黑猩猩在这些任务上的表现相当，它们在放置直棍的尝试中大约有一半的时间将直棍与凹槽平行对齐在 22.5° 范围内，并且与两根直棍相比，尝试放置 T 形棍的次数更多。这些发现提供了强有力的证据，表明簇绒卷尾猴和黑猩猩甚至不能可靠地将物体的一个突出轴向特征与表面对齐，并且在对齐问题中管理两个并发的异心空间关系对它们来说比管理两个顺序关系更具挑战性。相比之下，两岁以上的人类在类似的任务中表现出截然不同的感知运动能力：他们每次尝试都会将木棍可靠地对齐到凹槽，并且他们很容易同时管理两个异中心空间关系。对齐物体和一次管理两个或多个关系的限制极大地限制了非人类灵长类动物使用手动工具的方式。
Perceptuomotor functions that support using hand tools can be examined in other manipulation tasks, such as alignment of objects to surfaces. We examined tufted capuchin monkeys’ and chimpanzees’ performance at aligning objects to surfaces while managing one or two spatial relations to do so. We presented six subjects of each species with a single stick to place into a groove, two sticks of equal length to place into two grooves, or two sticks joined as a T to place into a T-shaped groove. Tufted capuchins and chimpanzees performed equivalently on these tasks, aligning the straight stick to within 22.5° of parallel to the groove in approximately half of their attempts to place it, and taking more attempts to place the T stick than two straight sticks. The findings provide strong evidence that tufted capuchins and chimpanzees do not reliably align even one prominent axial feature of an object to a surface, and that managing two concurrent allocentric spatial relations in an alignment problem is significantly more challenging to them than managing two sequential relations. In contrast, humans from 2 years of age display very different perceptuomotor abilities in a similar task: they align sticks to a groove reliably on each attempt, and they readily manage two allocentric spatial relations concurrently. Limitations in aligning objects and in managing two or more relations at a time significantly constrain how nonhuman primates can use hand tools.
