在这个实验中，研究人员创造了一种视觉错觉，让参与者的手指看起来和感觉好像被拉长到正常长度的两倍，直到手指折断，指尖脱落，然后用虚拟武器刺伤手指，同时测量皮肤电导有时指尖在参与者自己的控制下移动，有时它独立移动，奇怪的是，分离指尖破坏了对剩余残肢和指尖本身的潜在所有权，即使指尖在参与者的控制之下。这些结果对代理体现理论和工具使用理论有影响
For this experiment a visual illusion was created in which the participant's finger looked and felt as though it was being stretched to twice its normal length until it snapped and the tip came off It was then stabbed with virtual weapons while skin conductance was measured Sometimes the fingertip moved under the participant's own control and sometimes it moved independently Curiously, detaching the tip of the finger destroyed the underlying ownership for the remaining stump as well as for the tip itself, even when the tip was under participants' control These results have implications for theories of agency embodiment, and tool-use
