One of the main interests in the interpretation of the archaeological record and its variability within and through time and space is the production and use of past human stone tool technologies. Tool design and function are inevitably intertwined and strongly related to tool use. Understanding tool design provides information about early human technological adaptations and reflects human behaviour in the sense of conscious or unconscious decision-making. Nevertheless, the reason for major changes (including novelties, innovations, and loss) in past human stone tool technology is still poorly understood. A comprehensive approach focusing on tool function (What was the tool meant for?) and use (What was the tool used for?) can help to overcome this gap. While tool function (including performance) can be investigated experimentally, tool use can be addressed with use-wear analyses. These questions can be best investigated on technological systems showing little tool variability but strong evidence of maintenance and long-term use, such as Middle Palaeolithic industries.

过去基于石器性能的人类决策：测试原材料变化和边缘角度设计对工具功能影响的实验


解释考古记录及其在时间和空间内和随时间和空间的变化的主要兴趣之一是过去人类石器工具技术的生产和使用。工具的设计和功能不可避免地相互交织，并与工具的使用密切相关。了解工具设计提供了有关早期人类技术适应的信息，并反映了有意识或无意识决策意义上的人类行为。然而，过去人类石器技术发生重大变化（包括新颖性、创新性和失落）的原因仍然知之甚少。关注工具功能（该工具的用途是什么？）和使用（该工具的用途是什么？）的综合方法可以帮助克服这一差距。虽然可以通过实验研究工具功能（包括性能），但可以通过使用磨损分析来解决工具的使用问题。这些问题最好在技术系统上进行研究，这些技术系统显示出工具的可变性很小，但有强有力的维护和长期使用的证据，例如旧石器时代中期的工业。
