Putting oneself in the shoes of a digital alter ego becomes an increasingly relevant part of our everyday experience. In modern day psychology, these interactions can be examined within the frameworks of visual perspective taking and body ownership. Both target similar questions: What does it take, to become one with the avatar? When do we show the same behavior and make the same experiences, as if we were in its place? In this study, we want to address the role of action effect consistency for these concepts. We manipulated the participants' sense of agency over a task-irrelevant avatar in a Simon task by providing either corresponding or random action effects. These effects could be either embodied and therefore linked to the avatar (Experiment 1) or independent of it (Experiment 2). We used stimulus-response compatibility effects from the avatar's point of view as a measure for spontaneous visual perspective taking and a questionnaire to measure the perceived body ownership of the avatar. The results showed that corresponding action effects lead to increased spontaneous perspective taking of the avatar, regardless of whether the effect was linked to the avatar or not. Though the avatar compatibility effects were overall more pronounced in the embodied action effect condition. However, significant differences in perceived body ownership were only observed if the effects were linked to the avatar. The results might prove useful to further our understanding of subjective and objective measurements of interactions with avatars.
将自己置于数字替身的角色中，成为我们日常体验中越来越重要的一部分。在现代心理学中，可以在视觉视角和身体所有权的框架内研究这些交互。这两个目标都相似：需要什么才能与化身融为一体？当我们表现出相同的行为并获得相同的体验时，就好像我们处于它的位置一样？在这项研究中，我们想探讨动作效果一致性对这些概念的作用。我们通过在 Simon 任务中为参与者提供相应或随机的动作效果，来操纵他们对任务无关的化身的代理感。这些效果可以是体现的，因此与化身相关联（实验 1），也可以是独立的（实验 2）。我们使用从化身角度出发的刺激反应兼容性效应对自发性视觉视角进行测量，并使用问卷调查来测量对化身的感知身体所有权。结果表明，无论效果是否与化身相关联，相应的动作效果都会导致对化身的自发性视角增加。虽然在体现动作效果的条件下，化身兼容性效果总体上更为明显。但是，只有当效果与化身相关联时，才会观察到感知身体所有权的显著差异。这些结果可能有助于进一步理解与化身交互的主观和客观测量。
