据报道，长尾猕猴（Macaca fasciculis aurea；Mfa）的一个亚种在东南亚使用石器和特定技术来加工坚果，这种行为被称为“磅锤”。这项研究的目的是研究长尾猕猴的锤击行为的发展：这种行为形式是否可以单独学习，或者是否必须依赖于某些形式的社会学习。鉴于圈养时缺乏 Mfa，我们对一个高度相关的亚种（Macaca fasciculis fasciculis；Mff）的长尾猕猴进行了实验测试，为它们提供了展示磅锤击所需的生态材料。首先进行了基线观察，以观察在没有社会信息的情况下是否会自发出现锤击行为。由于情况并非如此，因此提供了不同程度的社会信息，最终全面展示了该行为。没有一个受试者（n = 31）在任何个人或社会学习条件下表现出重击行为。尽管这些数据并不支持个体学习是这种行为背后的假设，但也没有发现证据表明（至少）Mff 在社交中学习重击。我们提出，其他潜在相互作用的因素可能会决定这种行为是否出现在长尾猕猴的各个亚种中，并提供一种新颖的方法来测试社会和个体学习在动物工具使用发展中的作用。
A subspecies of long-tailed macaques (Macaca fascicularis aurea; Mfa) has been reported to use stone tools and a specific technique to process nuts in Southeast Asia, a behaviour known as ‘pound-hammering’. The aim of this study was to examine the development of pound-hammering in long-tailed macaques: whether this behavioural form can be individually learnt or whether it has to rely on some forms of social learning. Given the absence of Mfa from captivity, long-tailed macaques of a highly related subspecies (Macaca fascicularis fascicularis; Mff) were experimentally tested by providing them with the ecological materials necessary to show pound-hammering. A baseline was first carried out to observe whether pound-hammering would emerge spontaneously without social information. As this was not the case, different degrees of social information, culminating in a full demonstration of the behaviour, were provided. None of the subjects (n = 31) showed pound-hammering in any of the individual or social learning conditions. Although these data do not support the hypothesis that individual learning underlies this behaviour, no evidence was found that (at least) Mff learn pound-hammering socially either. We propose that other—potentially interacting—factors may determine whether this behaviour emerges in the various subspecies of long-tailed macaques, and provide a novel methodology to test the role of social and individual learning in the development of animal tool-use.
