三个实验报告解决的问题，什么样的视觉本体感受的信息是由年幼的婴儿拿起时，从事视觉探索的自我产生的运动，他们的腿投射到视频显示器。第一个实验的结果表明，3至5个月大的婴儿表现出自己的腿的正常视图和屏幕上的双腿的左右位置颠倒的视图之间的辨别。第二个实验的结果表明，没有这样的歧视时，腿的整体特征配置被遮挡。与实验1相关，这些结果表明婴儿对腿部的不变特征很敏感，特别是它们与身体其他部位的关系。最后，第三个实验的结果复制了婴儿的视觉偏好模式，对一个视图，扭转了看到和感觉到的整体运动方向性，使用连续的，而不是同时的视觉呈现帕拉digm。这些结果提供了进一步的证据，早期发展的一个多式联运校准的机构。这种校准被解释为身体图式的感性基础和生态自我的早期表达。
Three experiments are reported addressing the issue of what kind of visual-proprioceptive information is picked up by young infants when engaging in the visual exploration of self produced movements of their legs projected onto a video display. Results of the first experiment indicate that 3 to 5 month old infants show discrimination between a normal view of their own legs and a view that reverses the left-right location of both legs on the screen. Results of the second experiment show that there is no such discrimination when the overall featural configuration of the legs is occluded. In relation to Experiment 1, these results suggest that infants are sensitive to the invariant featural characteristics of the legs, in particular, how they relate to the rest of the body. Finally, results of the third experiment replicate infants' pattern of visual preference toward a view that reverses the seen and felt overall movement directionality, using a successive instead of a simultaneous visual presentation para digm. These results provide further evidence of the early development of an intermodal calibration of the body. This calibration is interpreted as the perceptual foundation of the body schema and the early expression of an ecological self.
