驾驶操作中反应选择与反应触发的加工关系

Rlationships of Selecting and Initiation Response in Driving Operations

实验结果揭示，在驾驶人机系统操作界面的离散交叠作业过程中：（１）使用不同反应通道（脚－手）不能消除对交叠作业的瓶颈性质干扰，因而也就不能有效提高第二作业绩效；（２）是反应选择而不是反应触发对驾驶操作信息加工具有瓶颈限制作用，反应选择是一个复杂的单通道（瓶颈）信息加工过程；（３）减少交叠作业的外部动作反应可有效提高作业绩效。

The following results are confirmed: (1)Using different response channel(foot hand) can not eliminate PRP, and can not raise performance of overlapping tasks in the operation interface of driving man machine system.(2) There is the nature of bottleneck in selecting response rather than in response initiation processing. The response selecting stage is a complex single channel information processing.(3) Reducing response times of overlapping task could raise the performance effectively.
