Recent research using the "rubber hand illusion" shows that the multisensory processes underlying body representations are markedly different in children of 4 to 9years and adults. In representing the position of their own hand in external space, children of this age rely more on the sight of the hand, and less on its proprioceptively felt position, than adults do. The current study investigated when during later childhood the balance between visual and proprioceptive inputs reaches an adult-like weighting. After inducing the rubber hand illusion in 10- to 13-year-olds, we asked participants to point, with eyes closed, to the perceived position of their hand. We found that pointing responses reached adult levels at 10 to 11years, showing that at this age children perceive hand location using an adult-like balance of sensory cues. We conclude that the multisensory foundations of the bodily self undergo a protracted period of development through early and mid-childhood, reaching an adult state by 10 to 11years.
最近利用“橡胶手错觉”进行的研究表明，4至9岁儿童和成年人在身体表征背后的多感官过程存在显著差异。在对外界空间中自己手部位置进行表征时，这个年龄段的儿童比成年人更依赖手部视觉，而较少依赖本体感觉所感知到的位置。当前研究调查了在童年后期视觉和本体感觉输入之间的平衡何时达到类似成年人的权重。在对10至13岁儿童诱发橡胶手错觉后，我们要求参与者闭眼指向他们所感知到的手部位置。我们发现，指向反应在10至11岁时达到成年人水平，表明在这个年龄儿童使用类似成年人的感官线索平衡来感知手部位置。我们得出结论，身体自我的多感官基础在童年早期和中期经历了一段漫长的发展时期，到10至11岁时达到成年状态。
