随着手机和便携式音乐播放器成为日常生活中的主食。当在执行其它任务的同时使用这些设备时，出现了关于可能发生的注意力缺陷的问题。在这里，我们使用了一个沉浸式虚拟环境中的过街任务来测试这种分散的注意力如何影响行人在穿过忙碌街道时的行为。36名参与者在虚拟环境中的手动跑步机上行走，通过一系列未标记的十字路口。在穿越时，参与者没有分心，从事免提手机交谈，或听iPod上的音乐。与听音乐相比，行人在用手机交谈时成功过马路的可能性更小，尽管他们在用手机交谈时需要更多的时间（类似于1.5秒）。这种成功率差异很大程度上是由于在规定的试验时间内（30秒）未能过马路造成的，这表明在用手机通话时，行人不太可能识别出过马路的机会并采取行动。(C)2009爱思唯尔有限公司保留所有权利。
With cellular phones and portable music players becoming a staple in everyday life. questions have arisen regarding the attentional deficits that might occur when such devices are used while performing other tasks. Here, we used a street-crossing task in an immersive virtual environment to test how this sort of divided attention affects pedestrian behavior when crossing a busy street. Thirty-six participants navigated through a series of unsigned intersections by walking on a manual treadmill in a virtual environment. While crossing, participants were undistracted, engaged in a hands free cell phone conversation, or listening to music on an iPod. Pedestrians were less likely to successfully cross the road when conversing on a cell phone than when listening to music, even though they took more time to initiate their crossing when conversing on a cell phone (similar to 1.5 s). This success rate difference was driven largely by failures to cross the road in the allotted trial time period (30 s), suggesting that when conversing on a cell phone pedestrians are less likely to recognize and act on crossing opportunities.
