两个实验研究了10岁和12岁的儿童和成人在沉浸式虚拟环境中骑自行车时如何拦截移动间隙。参与者骑着一辆真实的自行车沿着一条虚拟的道路行驶。在12个测试十字路口，参与者试图通过2个移动的汽车大小的街区之间的间隙，而不停止。这些障碍物是定时的，因此有时需要参与者调整他们的速度以通过差距。我们操纵可用的视觉信息，在实验1和实验2中的块流隔离的目标块。在这两个实验中，成年人比儿童有更多的时间。两组人在被要求放慢速度的时候都比被要求加快速度的时候有更多的时间。参与者的行为揭示了一个多阶段的拦截策略，不能用单调的控制律，如恒定的方位角策略来解释。一般性讨论部分侧重于发展过程中感知-行动耦合变化的可能来源，以及可能构成所观察到的拦截策略基础的特定任务限制。
Two experiments examined how 10- and 12-year-old children and adults intercept moving gaps while bicycling in an immersive virtual environment. Participants rode an actual bicycle along a virtual roadway. At 12 test intersections, participants attempted to pass through a gap between 2 moving, car-sized blocks without stopping. The blocks were timed such that it was sometimes necessary for participants to adjust their speed in order to pass through the gap. We manipulated available visual information by presenting the target blocks in isolation in Experiment 1 and in streams of blocks in Experiment 2. In both experiments, adults had more time to spare than did children. Both groups had more time to spare when they were required to slow down than when they were required to speed up. Participants’ behavior revealed a multistage interception strategy that cannot be explained by the use of a monotonic control law such as the constant bearing angle strategy. The General Discussion section focuses on possible sources of changes in perception-action coupling over development and on task-specific constraints that could underlie the observed interception strategy.
