多元素视觉跟踪和视觉搜索是两个需要视觉空间注意的任务。作者使用注意操作特征（AOC）方法来确定两个任务是否持续使用相同的注意资源（即，这两个任务是否相互排斥）。作者发现，观察者在同一试验中的搜索和跟踪能力明显优于两项任务相互排斥时的预测。事实上，跟踪和搜索的AOC与跟踪和听觉监测的AOC相似。额外的实验结果支持注意力转换帐户这种高水平的双任务性能，其中一个单一的注意力资源之间的有效切换跟踪和搜索。研究结果为视觉选择性注意体系结构和多元跟踪机制提供了重要约束。
Multielement visual tracking and visual search are 2 tasks that are held to require visual-spatial attention. The authors used the attentional operating characteristic (AOC) method to determine whether both tasks draw continuously on the same attentional resource (i.e., whether the 2 tasks are mutually exclusive). The authors found that observers can search and track within the same trial significantly better than would be predicted if the 2 tasks were mutually exclusive. In fact, the AOC for tracking and search is similar to that for tracking and auditory monitoring. The results of additional experiments support an attention-switching account for this high level of dual-task performance in which a single attentional resource is efficiently switched between the tracking and search. The results provide important constraints for architectures of visual selective attention and the mechanisms of multielement tracking.
