A COMPUTER TEST OF ACTUAL AND SIMULATED "BAC" IMPAIRMENT

该项目建议引入一种经过实验室测试的“视频游戏” 模拟饮酒高危人群的认知表现 和驾驶逮捕和碰撞：年轻的成年人，年龄18-24。 第一 该项目的第一阶段改进了实验室的软件和硬件 原型注意力分散任务（SEDI）。 第一阶段的最终产品将 是一个模拟SEDI，可以适应一个常见的可用 微型计算机系统（Apple II）。 第一阶段还评估新的模拟 通过复制先前的实验室研究， 与原型进行。 拟议的研究将确定坡度 并通过重复测量截取BAC损伤函数 一种将受试者暴露于安慰剂和两种酒精剂量的设计， sessions. 新的和以前收集的数据集将用于 在SEDI软件中写入“BAC障碍”，以便未来的参与者 在不饮酒的情况下也会产生损伤效应。 二期 评估障碍的可靠性和有效性， 模拟作为酒后驾驶对策在高中 驾驶员教育课程。 微型计算机SEDI应具有商用 吸引力，因为这将是一个低成本，便携式和娱乐性的驾驶 这是一个需要学生积极参与的过程。

The project proposes to introduce a laboratory-tested "videogame" simulation of cognitive performace to the highest risk group for drinking and driving arrests and crashes: the yound adult, age 18-24. The first phase of the project refines the software and hardware of a laboratory prototype divided-attention task (SEDI). The final product of Phase I will be a simulation of SEDI that can be adapted to a commonly available microcomputer system (Apple II). Phase I also evaluates the new simulation with a sample of young adults by replicating previous laboratory research conducted with the prototype. The proposed study will establish the slope and intercept of the BAC-impairment function with a repeated measures design that exposes subjects to placebo and two alcohol doses across sessions. New and previously collected data sets will then be used to write "BAC handicaps" into the SEDI software so that future participants can experience impairment effects without consuming alcohol. Phase II evaluates the reliability of the handicaps and the effectiveness of the simulation as a drinking and driving countermeasure in the high school driver education curriculum. The microcomputer SEDI should have commercial appeal because it will be a low cost, portable and entertaining driving simulation that requires active participation from the student.
