具身认知理论提出，我们通过在模拟过程中重新激活工具使用的感觉运动表征来部分地识别工具。如果运动模拟在工具识别中发挥因果作用，那么执行并发运动任务应该对有经验的工具和无经验的工具的识别进行差异化调节。我们试图检验这样的假设：不相容的并发运动任务通过直接操纵参与者的具体体验来调节学习与非学习对象的概念处理。我们训练一组人使用一套新颖的 3D 打印工具，假装他们正在为火星考古探险做准备（操作组）；我们训练了第二组来报告有关如何存储工具的声明性信息（存储组）。通过这种设计，两组对不同物体部分的熟悉度和视觉注意力相似，尽管他们的交互质量不同。学习后，参与者在执行并发运动任务或只是坐着休息时，对听觉呈现的工具名称进行熟悉程度判断。我们表明，运动状态依赖性有助于熟悉度判断；具体来说，在操纵组中，同时进行的运动任务促进了熟悉度，而在空间组中，坐着休息时，熟悉度得到了促进。这些结果首次直接表明，操作经验对熟悉与不熟悉物体的概念处理有不同的调节，这表明具身表征有助于识别工具。
Theories of embodied cognition propose that we recognize tools in part by reactivating sensorimotor representations of tool use in a process of simulation. If motor simulations play a causal role in tool recognition then performing a concurrent motor task should differentially modulate recognition of experienced vs. non-experienced tools. We sought to test the hypothesis that an incompatible concurrent motor task modulates conceptual processing of learned vs. non-learned objects by directly manipulating the embodied experience of participants. We trained one group to use a set of novel, 3-D printed tools under the pretense that they were preparing for an archeological expedition to Mars (manipulation group); we trained a second group to report declarative information about how the tools are stored (storage group). With this design, familiarity and visual attention to different object parts was similar for both groups, though their qualitative interactions differed. After learning, participants made familiarity judgments of auditorily presented tool names while performing a concurrent motor task or simply sitting at rest. We showed that familiarity judgments were facilitated by motor state-dependence; specifically, in the manipulation group, familiarity was facilitated by a concurrent motor task, whereas in the spatial group familiarity was facilitated while sitting at rest. These results are the first to directly show that manipulation experience differentially modulates conceptual processing of familiar vs. unfamiliar objects, suggesting that embodied representations contribute to recognizing tools.
