As some states allow motorists to use hands-free cell phones only while driving, this study was done to examine some braking responses to see if conversing on these two types of cell phones affects quick responding. College-age drivers (n=25) completed reaction time trials in go/no-go situations under three conditions: control (no cell phone or conversation), and conversing on hands-free and hand-held cell phones. Their task involved moving the right foot from one pedal to another as quickly as possible in response to a visual signal in a lab setting. Significantly slower reaction times, movement times, and total response times were found for both cell phone conditions than for the control but no differences between hands-free and hand-held phone conditions. These findings provide additional support that talking on cell phones, regardless if it is hands-free or hand-held, reduces speed of information processing.
由于一些州允许驾车者仅在开车时使用免提手机，因此开展了本研究以检查一些制动反应，看看使用这两种类型的手机进行交谈是否会影响快速反应。大学年龄的驾驶员（n = 25）在三种条件下的“通过/不通过”情境中完成反应时间试验：对照（不使用手机或交谈），以及使用免提手机和手持手机交谈。他们的任务是在实验室环境中，根据视觉信号尽快将右脚从一个踏板移到另一个踏板。结果发现，与对照相比，两种手机条件下的反应时间、移动时间和总反应时间均显著更慢，但免提手机和手持手机条件之间没有差异。这些发现进一步支持了这样的观点，即无论使用免提手机还是手持手机，打电话都会降低信息处理速度。
