本研究调查了与使用免提电话有关的不同类型的分心对驾驶性能的影响。本研究在电话交谈中使用了三种类型的言语干扰：随意交谈、简单的算术数字猜测和数字相加。12名成年人被要求在一个固定的驾驶模拟器中在封闭的高速公路上跟随领头车辆。结果表明，使用免提手机涉及语言和认知分心损害驾驶性能和技能。分心的类型产生显着不同的影响，对几个因变量：驾驶速度，车头时距（之间的距离的领导汽车和操纵的汽车），制动反应时间，和与领导汽车的碰撞次数。一般来说，对话中涉及的认知负荷越高，驾驶性能越差。
This study investigated the effect of different types of distractions related to use of a hands-free phone on driving performance. The study used three types of verbal distractors: casual conversation, simple arithmetic number guessing, and number adding, in the phone conversation. 12 adults were instructed to follow a lead vehicle on a closed-course highway in a fixed-based driving simulator. The results showed that use of a hands-free cellular phone involving verbal and cognitive distractions impaired driving performance and skill. Types of distraction produced significantly different effects on several dependent variables: the driving speed, headway (distance between the lead car and the manipulated car), brake reaction time, and number of collisions with the lead car. In general, the higher the cognitive load involved in the dialogue, the worse the driving performance.
