Unlike affordances involving stationary objects, affordances involving moving objects change over time. This means that actions must be tightly linked to decisions, making perceiving and acting on affordances involving moving objects challenging for children and adults alike. Here, we overview our program of research on how children and adults perceive and act on moving objects in the context of bicycling across roads in an immersive virtual environment. This work shows that although children attempt to adjust their actions to fit their risky decisions, they do not fully adjust their decisions to fit their action capabilities. This mismatch between child cyclists' decisions and actions may be a risk factor for car-bicycle collisions in late childhood and early adolescence.
与涉及静止物体的可供性不同，涉及移动物体的可供性会随时间变化。这意味着行动必须与决策紧密相连，这使得儿童和成人在察觉涉及移动物体的可供性并据此行动方面都颇具挑战。在此，我们概述了我们的研究项目，该项目聚焦于儿童和成人在沉浸式虚拟环境中骑自行车过马路的情境下，如何察觉并对移动物体采取行动。这项研究表明，尽管儿童试图调整自己的行动以契合其冒险的决策，但他们并未充分调整决策以适应自身的行动能力。儿童自行车骑行者的决策与行动之间的这种不匹配，可能是儿童晚期和青少年早期汽车与自行车碰撞事故的一个风险因素。
