THE USE OF MOBILE PHONES AND THEIR EFFECT ON RESOURCE ALLOCATION
研究驾驶时使用手机对认知负荷和注意力资源分配的影响，发现任务类型显著影响周边检测任务表现，但电话模式无显著影响。
The mobile phone has been the focal point for traffic safety for researches, laymen, and police. This study addresses the use of mobile phones when driving. Specifically, it explores mobile phones use and their effect on cognitive workload and attention resource allocation needed for safe driving. A secondary tasking methodology was used to evaluate the workload of the participants. That means that the participants were asked to perform a high response frequency parallel task, e.g. peripheral detection task (PDT), throughout the entire test route that was not relevant to driving. Effects of conversation type and telephone mode were compared to baseline conditions. The main findings of the study are that there is a significant effect of the task on the peripheral detection task performance but no effect of telephone modality on PDT performance. A significant effect of telephone modality was found on the dependent variable of mean speed.
