Understanding the effects of hand proximity to objects and tasks is critical for hand-held and near-hand objects. Even though self-avatars have been shown to be beneficial for various tasks in virtual environments, little research has investigated the effect of avatar hand proximity on working memory. This paper presents a between-participants user study investigating the effects of self-avatars and physical hand proximity on a common working memory task, the Stroop interference task. Results show that participants felt embodied when a self-avatar was in the scene, and that the subjective level of embodiment decreased when a participant's hands were not collocated with the avatar's hands. Furthermore, a participant's physical hand placement was significantly related to Stroop interference: proximal hands produced a significant increase in accuracy compared to non-proximal hands. Surprisingly, Stroop interference was not mediated by the existence of a self-avatar or level of embodiment.
理解手与物体和任务的接近程度对于手持和近手物体至关重要。尽管已经证明自我化身对于虚拟环境中的各种任务是有益的，但很少有研究调查化身手接近度对工作记忆的影响。本文介绍了一项参与者之间的用户研究，该研究调查了自我化身和物理手接近度对常见工作记忆任务（Stroop 干扰任务）的影响。结果表明，当自我化身在场景中时，参与者会感到被体现，并且当参与者的手与化身的手不重合时，主观体现水平会降低。此外，参与者的物理手放置与 Stroop 干扰显著相关：与非近端手相比，近端手的准确性显著提高。令人惊讶的是，Stroop 干扰不受自我化身的存在或体现水平的影响。
