Our major focus is the development of a driving simulator using a virtual display, with eye and head position monitoring. We chose driving as a test paradigm to investigate perceptual and cognitive function in a natural environment. Driving provides a good environment to study short-term cognitive information processing since crucial unprocessed information leads to an obvious behavioral outcome in driver errors. It also allows investigation of natural behavior in a situation that is still constrained enough to draw theoretically rigorous inferences. The relation of attention deficits to driver errors has been well established. Such deficits are far more correlated with accident records than visual deficits. One of the problems with classical paradigms is arranging for `unattended' stimuli to influence performance without covert attention shifts. This problem is almost always approached by using very brief presentations, which leaves open the question of how attention is deployed under natural conditions. In our driving simulator we can observe an extended behavioral sequence while maintaining tight experimental control. Covert attention shifts can be controlled by manipulating the demands of the primary driving task. Recent Progress. The car was mounted on a six degree-of-freedom motion platform which provides vestibular input.

我们的主要关注点是开发一个使用 虚拟显示，具有眼睛和头部位置监控功能。我们选择了 将驾驶作为一种测试范式来研究知觉和认知 在自然环境中发挥作用。驾驶提供了一种很好的 研究短时认知信息加工的环境 关键的未经处理的信息会导致明显的行为结果 驱动程序错误。它还允许调查自然行为在 一种仍然受到足够限制的情况，从理论上说 严谨的推论。注意缺陷与驾驶员的关系 错误已经得到了很好的证实。这样的赤字远远超过 与事故记录相关的因素多于视力缺陷。其中一个 经典范式的问题正在被安排为“无人值守” 在不转移隐蔽注意力的情况下影响表现的刺激。 这个问题几乎总是通过使用非常简短的 演讲，这留下了一个悬而未决的问题，即注意力有多大 在自然条件下部署。在我们的驾驶模拟器中，我们可以 观察扩展的行为序列，同时保持紧凑 实验对照。秘密的注意力转移可以通过以下方式控制 操纵主要驾驶任务的需求。近期 进步。这辆车是以六自由度的运动方式安装的 提供前庭输入的平台。
