成年人的身体表征受到多感官信息和身体知识（如可能的姿势）的限制。本研究（N = 180）测试了儿童的类似限制。使用橡胶手错觉与成人和6- 7奥尔兹，我们测量本体感受漂移（手定位的指数）和感觉手所有权的评级。假手与参与者自己的手要么一致，要么不一致。在不同年龄段，姿势一致性和视觉-触觉一致性产生了更大的向假手的漂移。所有权评级较高，一致的视觉触觉信息，但不受姿势。在儿童和成人中，身体表征的限制类似，这表明儿童有敏感，强大的机制来维持身体自我感。
Adults' body representation is constrained by multisensory information and knowledge of the body such as its possible postures. This study (N = 180) tested for similar constraints in children. Using the rubber hand illusion with adults and 6- to 7-year olds, we measured proprioceptive drift (an index of hand localization) and ratings of felt hand ownership. The fake hand was either congruent or incongruent with the participant's own. Across ages, congruency of posture and visual-tactile congruency yielded greater drift toward the fake hand. Ownership ratings were higher with congruent visual-tactile information, but unaffected by posture. Posture constrains body representation similarly in children and adults, suggesting that children have sensitive, robust mechanisms for maintaining a sense of bodily self.
