在四个实验中，我们解决的问题是否可以选择几个视觉对象自愿（外源），然后在多对象跟踪范式跟踪，如果是这样，是否选择涉及不同的过程。实验1表明，项目确实可以根据其标签进行选择。实验2表明，选择一组自动（外源）选择的补充集-例如，选择所有对象不闪烁-观察员需要额外的时间，并给予1080毫秒，他们能够选择和跟踪他们以及那些自动选择。实验3表明，上一个实验中所需的额外时间不能仅仅归因于将注意力从最初的自动选择中脱离所需的时间。实验4表明，当有更多的目标时，增加的时间提供了单调的更大的好处，这表明一个串行过程。这些结果进行了讨论的视觉指数（FINST）理论，假设视觉指数被捕获的数据驱动的过程。研究表明，主动分配的注意力可以促进感兴趣对象的自动注意捕获。
In four experiments we address the question whether several visual objects can be selected voluntarily (exogenously) and then tracked in a Multiple Object Tracking paradigm and, if so, whether the selection involves a different process. Experiment 1 showed that items can indeed be selected based on their labels. Experiment 2 showed that to select the complement set to a set that is automatically (exogenously) selected--e.g. to select all objects not flashed--observers require additional time and that given 1080 ms they were able to select and track them as well as those selected automatically. Experiment 3 showed that the additional time needed in the previous experiment cannot be attributed solely to time required to disengage attention from the initially automatic selections. Experiment 4 showed that the added time provides a monotonically greater benefit when there are more targets, suggesting a serial process. These results are discussed in relation to the Visual Index (FINST) theory which assumes that visual indexes are captured by a data-driven process. It is suggested that voluntarily allocated attention can be used to facilitate the automatic attention capture by objects of interest.
