三组婴儿，在他们的年龄和行走经验不同，提出了在一个移动的走廊光流，和姿势调整进行了测量。孩子们要么站着不动，要么在这条走廊里来回走动，有两种情况。在第一个实验中，走廊是整洁的;在第二个实验中，通过在路径上放置障碍物（橡胶交通塔）来创建引导任务。对于站立试验，两种条件之间的姿势反应没有显著差异。对于步行试验，儿童在障碍物存在的情况下更容易蹒跚和摔倒。看来，通过一个混乱的环境中转向增加施加光流期间的姿势扰动。这些结果表明，两个离散的功能，保持姿势稳定性和转向，参与运动，并指导不同的信息方面的光流。随着年龄的增长和行走经验的增加，孩子们可以学会区分这两种类型的信息，为他们提供更好地整合这两种并发功能的方法。
Three groups of infants, differing in their age and walking experience, were presented with optical flow in a moving hallway, and postural adjustments were measured. Children either stood still, or walked back and forth within this hallway in two conditions. In the first, the hallway was uncluttered; in the second, a guidance task was created by placing obstacles (rubber traffic pylons) along the path. For standing trials, there were no significant differences in postural responses between the two conditions. For walking trials, children staggered and fell more often in the presence of obstacles. It appears that steering through a cluttered environment increases postural perturbation during imposed optical flow. These results suggest that two discrete functions, maintaining postural stability and steering, are involved in locomotion, and are guided by different informational aspects of optical flow. Increasing age and walking experience allows children to learn to distinguish between these two types of information, providing them with a means for better integrating these two concurrent functions.
