在过去的几十年里，科学家们一直在质疑人类精湛掌握工具的起源。在猴子、健康参与者和脑损伤患者身上进行的开创性研究主要集中在工具使用导致的空间表征的可塑性变化。最近，我们专注于工具使用必须对感觉运动系统施加的修改，并强调了大脑用来控制我们动作的身体表征水平上的可塑性变化，即身体图式。工具使用的证据正在出现，以影响对身体的更多基于视觉和概念的表现，例如身体形象。在这里，我们提供了一个批判性的回顾，不同的工具使用范例已经和应该被用来尝试解开负责将工具整合到不同身体表示中的关键特征。我们将得出结论，工具的使用可能为研究高阶体表征及其可塑性提供一种非常有价值的手段。
Over the last decades, scientists have questioned the origin of the exquisite human mastery of tools. Seminal studies in monkeys, healthy participants and brain-damaged patients have primarily focused on the plastic changes that tool-use induces on spatial representations. More recently, we focused on the modifications tool-use must exert on the sensorimotor system and highlighted plastic changes at the level of the body representation used by the brain to control our movements, i.e., the Body Schema. Evidence is emerging for tool-use to affect also more visually and conceptually based representations of the body, such as the Body Image. Here we offer a critical review of the way different tool-use paradigms have been, and should be, used to try disentangling the critical features that are responsible for tool incorporation into different body representations. We will conclude that tool-use may offer a very valuable means to investigate high-order body representations and their plasticity.
