人机操作界面中有或无外部反应对后继作业的干扰作用

实验结果提示：在高速复杂人机系统操作界面的优化设计中，有或无外部反应都不能消除对后继作业的瓶颈干扰。但是，有外部反应比无外部反应，对后继作业的瓶颈干扰更大；无外部反应降低了瓶颈的干扰强度，从而显示出提高了被交叠作业绩效的趋向。另外，降低反应选择复杂度可有效提高被交叠作业的绩效

Effects of External Response on Succeeding Operation in Man-Machine Interface

The results show, that in the optimum design of speedy and complex man-machine operation interface,whether there is any external response,the psychological refractory period(PRP) interference could not be eliminated,and the interference is greater when the external response exists. However,the intensity of PRP interference is reduced when there is no response.It shows that the performance of succeeding operation is raised.By lowering the complexity of response selectivity,the performance of succeeding operation could be raised.
