项目摘要

DESCRIPTION (provided by applicant): Reducing unintentional injuries is one of the top ten priorities of the Healthy People 2010 initiative. Injury prevention clearly plays an integral role in children's health, as unintentional injuries are the leading cause of death in children and young adults. Bicycle crashes are among the most common causes of severe injuries in late childhood and early adolescence. Motor vehicles are involved in approximately one-third of all bicycle- related brain injuries and in 90% of all fatalities resulting from bicycle crashes. A critical first step in developing programs to prevent collisions between child cyclists and motor vehicles is understanding why such collisions occur. The goal of this multi-disciplinary research proposal is to examine how immature perceptual-motor functioning puts children at risk for car-bicycle collisions when crossing roads. Using an immersive, interactive bicycling simulator, we will examine how two important aspects of perceptual-motor development influence road-crossing behavior. The first is coordinating motor movement with visual information. A robust finding from our research on children's road-crossing behavior is that children choose the same size gaps as adults, but leave less headway when they start to cross. Consequently, child cyclists end up with far less time to spare when they clear the path of the oncoming car. This puts child cyclists at greater risk for a collision because they have less time available to recover from an error such as a foot slipping off the pedal. The second aspect of perceptual-motor development we will address is flexibly adapting movement to changing circumstances. Skilled road crossing requires that cyclists adjust quickly to changes such as the distribution of gap sizes. The first set of proposed experiments will test hypotheses about why children leave less headway when starting off than do adults. These include 1) immature movement preparation strategies, 2) problems with making "go-no go" decisions, and 3) difficulty with synchronizing self and object movement. The second set of experiments will examine how children adjust their road-crossing behavior in response to changing circumstances and how these experiences influence later road-crossing behavior. By bringing together the study of basic and applied issues into a single program of research, this work will contribute both to our understanding of the development of perceptual-motor functioning and to our understanding of the underlying causes of child bicycling injuries.
描述(由申请人提供):减少无意的伤害是《健康人民2010年计划》倡议的十大优先事项之一。预防伤害显然在儿童健康中起着不可或缺的作用,因为无意的伤害是儿童和年轻人死亡的主要原因。自行车撞车是童年和青春期初期严重伤害的最常见原因之一。机动车涉及所有与自行车相关的脑部受伤的大约三分之一,而自行车撞车造成的所有死亡人数中有90%。制定计划以防止儿童骑自行车者和汽车之间发生碰撞的计划的关键第一步是了解为什么发生这种碰撞。这项多学科研究建议的目的是研究未成熟的感知运动功能如何使儿童在越过道路时有骑车碰撞的风险。使用沉浸式,交互式骑自行车的模拟器,我们将研究感知运动发展的两个重要方面如何影响道路交叉行为。首先是与视觉信息协调运动运动。从我们对儿童道路行为的研究中发现的强劲发现是,儿童选择与成年人相同的尺寸差距,但是当他们开始越过时,他们的进展较小。因此,当儿童骑自行车的人清理迎面而来的汽车路径时,最终会少留时间。这使儿童骑自行车的人面临更大的碰撞风险,因为他们从错误中恢复的时间更少,例如脚从踏板上滑下来。我们将要解决的感知运动发展的第二个方面是灵活地适应不断变化的环境。熟练的道路横道要求骑自行车的人迅速适应变化,例如差距的分布。第一组提出的实验将检验关于为什么儿童在开始时离开的进展比成年人少的假设。其中包括1)不成熟的运动准备策略,2)做出“ go-no go”决策的问题,以及3)难以同步自我和对象运动。第二组实验将研究儿童如何响应不断变化的环境以及这些经历如何影响后来的道路行为,如何调整其道路行为。通过将基本问题和应用问题的研究汇总到一个研究计划中,这项工作将有助于我们理解感知运动功能的发展,又有助于我们对儿童自行车伤害的根本原因的理解。
