在这个模拟过马路的研究中，我们评估了两名参与者视觉判断他们是否可以过马路的能力，以及他们的适应性步行行为。为此，研究人员向参与者展示了实验室内的一条道路，在这条道路上，一辆自行车从不同的距离以不同的速度靠近。8名5-7岁的儿童，10名10-12岁的儿童和10名成年人被要求口头判断他们是否可以过马路，如果可能的话，他们真的走过马路。结果表明，言语判断与实际过马路的判断并不相似。在判断的安全性和准确性方面，各组之间没有差异，尽管最年轻的一组往往更谨慎。所有小组似乎都使用了一种策略，根据距离和接近的自行车的速度来过马路。小孩子在过马路前要比大一点的孩子和成年人等更长的时间。所有小组都根据自行车到达的时间调整他们的穿越时间。这些研究结果与生态心理学方法以及感知视觉（即言语判断）和行动视觉（即实际穿越）之间的假定分离有关。(c) 2004 Elsevier Ltd.版权所有。
In this road-crossing simulation study, we assessed both participant's ability to visually judge whether or not they could cross a road, and their adaptive walking behavior. To this end, participants were presented with a road inside the laboratory on which a bike approached with different velocities from different distances. Eight children aged 5-7, ten children aged 10-12, and ten adults were asked both to verbally judge whether they could cross the road, and to actually walk across the road if possible. The results indicated that the verbal judgments were not similar to judgments to actually cross the road. With respect to safety and accuracy of judgments, groups did not differ from each other, although the youngest group tended to be more cautious. All groups appeared to use a strategy to cross the road based both on the distance and the velocity of the approaching bike. Young children waited longer on the curb before crossing the road than older children and adults. All groups adjusted their crossing time to the time-to-arrival of the bike. These findings are discussed in relation to the ecological psychological approach and the putative dissociation between vision for perception (i.e. verbal judgment) and vision for action (i.e. actual crossing).
