【摘要】 这是一项关于操作人员的心理负荷测量的实验研究。目的是为了确定哪一种第二任务的方法对测量心理负荷更灵敏。实验以追踪活动为第一任务,以心算、回忆随机数、对偶联想为第二任务。用第二任务操作水平的变化来测定不同难度的第一任务。结果表明,心算比回忆随机数、对偶联想更灵敏。更多还原

【Abstract】 This is an experiment on workload measurement of human operators.Its purpose is to determine which secondary task is more sensitive in work-load measurement. Our experiment treats tracking performance as theprimary task and mental arithmetic, recall of random digit and associationas the secondary tasks. The change in the operation of the secondarytasks is used as a measurement of different difficulty levels in the primarytask. The results show that mental arithmetic is most sensitive.更多还原
