Successfully perceiving and acting on dynamic affordances is critical for children and adults to function. In our work, we look at how children cross roads as a model for understanding how they learn to perceive and act on dynamic affordances. Ten‐ to 14‐year‐old children and adults ride an interactive bicycling simulator through an immersive virtual environment where they cross intersections with continuous cross traffic. We consistently find developmental and individual differences in children's ability to tightly time their entry into the roadway relative to the lead car in the gap. Given that children do not adjust their gap choices to match their less precise timing abilities, children take more risks when crossing roads than adults. We conclude by discussing possible reasons for these developmental differences in movement timing.

在横穿交通拥挤的道路上，儿童如何感知动态行为并采取行动？

成功地感知动态的能力并采取行动，对于儿童和成人的正常运作至关重要。在我们的工作中，我们将儿童如何过马路作为一种模型，以了解他们如何学习感知动态行为能力并采取行动。10至14岁的儿童和成人在沉浸式虚拟环境中乘坐互动式自行车模拟器，在该环境中，他们通过连续的交叉路口穿越十字路口。我们始终发现，相对于差距较大的领头车，儿童在紧紧地进入车道上的能力方面存在发育和个体差异。鉴于儿童没有调整他们的间隙选择以匹配他们不太精确的计时能力，因此儿童过马路时比成人承担更大的风险。最后，我们讨论了运动时间上这些发育差异的可能原因。
