The rubber hand illusion (RHI) is a widely applied paradigm to investigate changes in body representations. Extensive scientific interest has produced a great variability in the observed results and many contradictory findings have been reported. Taking into account the numerous variations in the experimental implementation of the RHI, many of these contradictive findings can be reconciled, but to date a thorough analysis of the methodological differences between RHI studies is lacking. Here we summarize and analyse methodological differences between RHI studies. In distinction from other reviews focusing on the integration of findings from various studies, the present paper is devoted to the differences in (i) the experimental setup, (ii) the method used to induce the RHI, (iii) the quantification of its effects, and (iv) aspects of the experimental design and data analysis. This approach will provide a reference frame for the interpretation of previous studies as well as for the design of future studies.
橡胶手错觉（RHI）是一种广泛应用于研究身体表象变化的范式。大量的科学研究产生了观察结果的巨大差异，许多相互矛盾的发现已经被报道。考虑到 RHI 的实验实施有许多变化，许多相互矛盾的发现是可以调和的，但迄今为止，还缺乏对 RHI 研究方法差异的全面分析。在这里，我们总结并分析了 RHI 研究中的方法学差异。与其他侧重于整合来自不同研究的发现的综述不同，本文致力于（i）实验设置，（ii）诱导 RHI 所使用的方法，（iii）其效果的量化，以及（iv）实验设计和数据分析的方面的差异。这种方法将为解释以前的研究以及设计未来的研究提供一个参考框架。
