In order to explore the selective attention mechanism and the dual-task information-processing model, two experiments were carried out involving a visual search task and a visual detection task. The results showed that the early period of attention selection is controlled in a bottom-up manner. With respect to the dual-task information-processing model, the results showed that the central information-processing model would include a sequence model for tasks that use the same perception resource, causing a bottleneck in information processing. Our study suggests that a simple and prominent signal could be used to attract drivers' attention prior to the emergent events. Moreover, any human-machine interface design in driving-associated systems should consider this information-processing bottleneck. With respect to signal type, targeted and easy to categorize were two useful elements to consider.
为了探究选择性注意机制和双任务信息处理模型，进行了两项实验，其中包括视觉搜索任务和视觉检测任务。结果表明，注意选择的早期阶段是由自下而上的方式控制的。关于双任务信息处理模型，结果表明，中央信息处理模型将包括一个针对使用相同感知资源的任务的序列模型，这会导致信息处理出现瓶颈。我们的研究表明，在突发事件发生之前，可以使用简单且突出的信号来吸引驾驶员的注意力。此外，任何与驾驶相关系统中的人机界面设计都应考虑这种信息处理瓶颈。关于信号类型，有针对性且易于分类是两个需要考虑的有用因素。
