两个实验报告表明，视觉搜索信号从一些潜在的信号源在持续的监测任务是依赖于以前的视觉负荷的历史。结果表明，在负载的时间和空间变化产生性能递减，偶尔增量，不能从静态负载实验预测。这些数据与以前试图解释与工作负载历史相关的性能变化的尝试不一致。一个解释是提供在信息处理策略的持续性在不断变化的任务条件。
Two experiments are reported that demonstrate that visual search for a signal from a number of potential signal sources in a sustained monitoring task is dependent upon previous visual-load history. It is shown that both temporal and spatial variations in load produce performance decrements, and occasionally increments, that cannot be predicted from static-load experiments. These data are not consistent with previous attempts to explain performance changes associated with workload history. An interpretation is offered in terms of the persistence of information-processing strategies across changing task conditions.
