在研究时间在脑力负荷中的作用时，作者提出了一个不同的视角来看待评估问题。心理负荷以三个维度表示，其轴代表有效行动时间、与期望目标状态的感知距离、实现时间限制目标所需的努力水平。这种表示允许生成的等动力工作负荷轮廓，将操作员的技能和equifinality的努力的因素。动态任务重新分配的自适应接口，使用这种形式的评估，以调和的联合目标的稳定的操作员加载和可接受的主要任务的性能由整个系统。<>
In examining the role of time in mental workload, the authors present a different perspective from which to view the problem of assessment. Mental workload is plotted in three dimensions, whose axes represent effective time for action, perceived distance from desired goal state, level of effort required to achieve the time-constrained goal. This representation allows the generation of isodynamic workload contours that incorporate the factors of operator skill and equifinality of effort. An adaptive interface for dynamic task reallocation is described that uses this form of assessment to reconcile the joint aims of stable operator loading and acceptable primary task performance by the total system.<>
