Understanding the function of a tool is an essential step in learning to use a tool. This aspect of interaction with tools has hitherto been neglected. Unlike acquiring the expertise in handling a new tool, which involves practice, understanding its function usually only requires a single observation of the tool being used. The present study uncovers the neural areas involved in this transient understanding effect as a left-lateralized pattern involving prefrontal and mediotemporal areas. We suggest that activation in this network reflects the conceptual encoding of the function of new tools as it is independent from the well-known tool-related networks. We demonstrate that understanding the function of a new tool does not rely on known semantic or motor networks involved in processing tool use.
理解工具的功能是学习使用工具的重要步骤。到目前为止,这方面的工具交互一直被忽视。与需要练习才能掌握使用新工具的专业技能不同,理解工具的功能通常只需要观察工具的一次使用。本研究揭示了涉及前额叶和中颞叶区域的这种左侧偏侧化模式的神经区域,这些区域参与了这种短暂的理解效应。我们认为,该网络的激活反映了新概念的编码,即新工具的功能,因为它独立于已知的与工具相关的网络。我们证明了理解新工具的功能并不依赖于处理工具使用过程中涉及的已知语义或运动网络。
