本文的目的是进一步理解的实施1）分析确定的组件定义的实施，2）增加的可比性和标准化的测量实施跨实验通过提供一个通用的实施问卷，是有效的和可靠的，和3）激励研究人员使用标准化的问卷。在本文中，我们验证数值和完善我们以前提出的实施例问卷。我们从九个实验中收集了数据，超过400份问卷，这些问卷使用了原始实施例25项问卷的全部或部分。进行分析以消除非通用问题、冗余问题和与其他问题不强相关的问题。我们进一步对子量表进行数字分类和加权，并确定具体化由外观，反应，所有权和多感官的相互关联的类别组成。最后的问卷包括16个问题和四个相互关联的分量表，每个分量表内的高可靠性，Chronbach的α值从0.72到0.82不等。原始的和完善的问卷调查结果进行了比较，在所有九个实验和详细的三个实验。与原始问卷相比，更新后的问卷产生了更宽范围的实施例分数，能够检测到自我化身的存在，并且能够辨别出30岁以上的参与者与30岁以下的参与者相比具有显着更低的实施例分数。删除的问题和社区感兴趣的进一步研究进行了讨论。
The aim of this paper is to further the understanding of embodiment by 1) analytically determining the components defining embodiment, 2) increasing comparability and standardization of the measurement of embodiment across experiments by providing a universal embodiment questionnaire that is validated and reliable, and 3) motivating researchers to use a standardized questionnaire. In this paper we validate numerically and refine our previously proposed Embodiment Questionnaire. We collected data from nine experiments, with over 400 questionnaires, that used all or part of the original embodiment 25-item questionnaire. Analysis was performed to eliminate non-universal questions, redundant questions, and questions that were not strongly correlated with other questions. We further numerically categorized and weighted sub-scales and determined that embodiment is comprised of interrelated categories of Appearance, Response, Ownership, and Multi-Sensory. The final questionnaire consists of 16 questions and four interrelated sub-scales with high reliability within each sub-scale, Chronbach's & alpha; ranged from 0.72 to 0.82. Results of the original and refined questionnaire are compared over all nine experiments and in detail for three of the experiments. The updated questionnaire produced a wider range of embodiment scores compared to the original questionnaire, was able to detect the presence of a self-avatar, and was able to discern that participants over 30 years of age have significantly lower embodiment scores compared to participants under 30 years of age. Removed questions and further research of interest to the community are discussed.
