Abstract

The rubber hand illusion is a well-known experiment that allows manipulation of one's own body experience. The original questionnaire gauges both the illusion experience and unforeseen experiences acting as control statements. In particular, two statements pertain to the referral of touch originating from the rubber hand (RoT), and one concerns the feeling of ownership of the rubber hand (SoO). Despite its prominence, the rubber hand illusion questionnaire has not undergone thorough examination of its psychometric properties. The literature reveals a tendency to use RoT and SoO statements interchangeably. In this study, we employed Exploratory Graph Analysis to explore the item structure and compared the correlation between SoO and RoT items in various conditions. While SoO and RoT are closely linked, our findings suggest potential separation. SoO and RoT statements consistently correlate, yet hints emerge that RoT might represent a distinct facet of the illusion. Correlations diminish beyond the perihand space, indicating a nuanced relationship. Additionally, moderate relationships between control statements and those measuring the illusion suggest that even control statements are modulated by the illusion experience. This study underscores the need for further exploration into the psychometric properties of body illusion questionnaires, prompting reflections on the interpretation in light of these results.

橡胶手幻觉问卷:对所有权、触摸转介和控制声明的探索性图表分析。
橡皮手幻觉是一个著名的实验,它可以操纵人们自己的身体体验。原始问卷同时测量幻觉体验和作为对照语句的意外体验。其中,两份陈述涉及来自橡皮手的触感(RoT),一份涉及橡皮手的拥有感(SoO)。尽管橡皮手错觉问卷很受重视,但它的心理测量学特性却没有经过彻底研究。文献显示,人们倾向于交替使用 "RoT "和 "SoO "陈述。在本研究中,我们采用了探索性图表分析法来探索项目结构,并比较了不同条件下 SoO 和 RoT 项目之间的相关性。虽然 SoO 和 RoT 密切相关,但我们的研究结果表明它们之间可能存在分离。SoO和RoT语句之间始终存在相关性,但我们发现,RoT可能代表了幻觉的一个独特方面。相关性在手部周围空间之外逐渐减弱,这表明两者之间存在着微妙的关系。此外,控制陈述与测量幻觉的陈述之间的适度关系表明,即使是控制陈述也会受到幻觉体验的调节。这项研究强调了进一步探索身体错觉问卷心理测量特性的必要性,并促使我们根据这些结果对解释进行反思。
