身体自我是由多感官信息构建的。然而，很少有人知道多感官发展和自我意识的出现之间的关系。我们通过测量幼儿（4至9岁）和成人的橡胶手错觉的强度来研究这个问题。手间指向表明，儿童和成人一样敏感的手的位置，这表明，视觉触觉路径的身体自我成熟至少4岁的视觉触觉同步线索。然而，无论同步线索，儿童的感知手的位置更接近橡胶手比成人的感知手的位置。这表明了第二个基于视觉本体感受信息的后期成熟过程。此外，外显体验只与视觉-触觉过程有关。这些发现表明，在生命早期的身体表征的两个分离的过程，他们质疑目前的模型的身体表征和所有权在成年。
The bodily self is constructed from multisensory information. However, little is known of the relation between multisensory development and the emerging sense of self. We investigated this question by measuring the strength of the rubber-hand illusion in young children (4 to 9 years old) and adults. Intermanual pointing showed that children were as sensitive as adults to visual-tactile synchrony cues for hand position, which indicates that a visual-tactile pathway to the bodily self matures by at least 4 years of age. However, regardless of synchrony cues, children's perceived hand position was closer to the rubber hand than adults' perceived hand position was. This indicates a second, later-maturing process based on visual-proprioceptive information. Furthermore, explicit feelings of embodiment were related only to the visual-tactile process. These findings demonstrate two dissociable processes underlying body representation in early life, and they call into question current models of body representation and ownership in adulthood.
