Capacity Equivalence Curves: A Double Trade-Off Curve Method for Equating Task Performance
描述并评估了一种用于开发心理负荷量表的双任务技术，即双重权衡曲线方法，可用于等值不同任务的次级任务绩效水平。
A dual-task technique for developing mental workload scales was described and evaluated. This technique, the method of double trade-off curves, can be used to equate secondary task performance levels of different tasks. The results from two different mental workload experiments were consistent with the assumptions underlying the technique.
