A capacity for constructing new tools, or using old tools in new ways, to solve novel problems is a core feature of what it means to be human. Yet current evidence suggests that young children are surprisingly poor at innovating tools. However, all studies of tool innovation to date have been conducted with children from comparatively privileged Western backgrounds. This raises questions as to whether or not previously documented tool innovation failure is culturally and economically specific. In the current study, thus, we explored the innovation capacities of children from Westernized urban backgrounds and from remote communities of South African Bushmen. Consistent with past research, we found tool innovation to occur at extremely low rates and that cultural background had no bearing on this. The current study is the first to empirically test tool innovation in children from non-Western backgrounds, with our data being consistent with the view that despite its key role in human evolution, a capacity for innovation in tool making remains remarkably undeveloped during early childhood.
构建新工具或以新方式使用旧工具来解决新问题的能力是人类本质的核心特征。然而,目前的证据表明,幼儿在工具创新方面出奇地差。然而,迄今为止所有关于工具创新的研究都是针对来自相对优越的西方背景的儿童进行的。这就引发了一个问题,即先前记录的工具创新失败是否具有文化和经济特殊性。因此,在当前的研究中,我们探索了来自西方化城市背景的儿童以及南非布须曼人偏远社区儿童的创新能力。与过去的研究一致,我们发现工具创新的发生率极低,而且文化背景对此没有影响。本研究首次对来自非西方背景的儿童的工具创新进行了实证测试,我们的数据与以下观点一致:尽管创新能力在人类进化中起着关键作用,但在幼儿期,工具制造方面的创新能力仍然非常不发达。
