The rubber hand illusion (RHI) is a much-studied bodily illusion that has been used in a wide number of populations to investigate the plasticity of the mental body representation. In adult participants, the wide adoption of the illusion has led to a proliferation of experimental variations of the illusion, and with that, considerable apparent inconsistencies in both empirical results and conceptual interpretations. In turn, this makes it challenging to integrate empirical findings and to identify what those findings together can tell us about the representation of the body in the brain. More recently, scientists have started applying the illusion to populations of children, in order to better understand how body representations develop in both typically developing children and in clinical populations. With this field now starting to expand, we believe it is both urgent and important to prevent unintended methodological variability from hindering the consistency of the paediatric literature as it has the adult literature. With this aim in mind, we review the 12 currently available paediatric RHI studies, and summarise their key methodological choices and conceptual definitions. We highlight a number of important discrepancies, particularly where seemingly equivalent analysis choices might significantly affect the interpretation of results, and make recommendations for future studies. We hope this will allow this important and emerging field to benefit from the synergy that results from multiple studies using convergent and consistent empirical methods.

儿童的橡胶手错觉:我们在测量什么?

橡胶手错觉 (RHI) 是一种经过大量研究的身体错觉,已被广泛用于研究心理身体表征的可塑性。在成年参与者中,幻觉的广泛采用导致了幻觉的实验变化的激增,因此,经验结果和概念解释都存在相当大的明显不一致。反过来,这使得整合经验发现并确定这些发现可以告诉我们关于身体在大脑中的表征的内容变得具有挑战性。最近,科学家们开始将这种错觉应用于儿童群体,以更好地了解身体表征如何在正常发育的儿童和临床人群中发展。随着这个领域现在开始扩大,我们认为,防止意外的方法学变异阻碍儿科文献的一致性既紧迫又重要,因为它有成人文献。考虑到这一目标,我们回顾了目前可用的 12 项儿科 RHI 研究,并总结了它们的关键方法选择和概念定义。我们强调了许多重要的差异,特别是在看似等效的分析选择可能会显着影响结果解释的情况下,并为未来的研究提出建议。我们希望这将使这个重要的新兴领域能够从使用趋同和一致的经验方法的多项研究产生的协同作用中受益。
