在跟踪空间中移动的物体时，人类通常会关注物体的空间位置，并随着时间的推移更新这些信息。地表特征在多大程度上有助于跟踪？在这项研究中，我们要求参与者追踪相同或唯一颜色的物体。当物体颜色独特时，跟踪功能得到增强。当干扰物和目标之间的距离较小时，效果会更大，但当物体每秒改变1到4次颜色时，效果就会消失，即使在任何时刻它们总是唯一的颜色。此外，与跟踪相同的物体相比，跟踪唯一颜色的物体对次要颜色记忆任务的损害更大，并且在工作记忆中保留几种颜色消除了跟踪唯一颜色物体的优势。与以往的研究表明特征信息在跟踪过程中被保留得很差相反，这些发现表明表面特性被存储在视觉工作记忆中以促进跟踪性能。
When tracking moving objects in space humans usually attend to the objects’ spatial locations and update this information over time. To what extent do surface features assist attentive tracking? In this study we asked participants to track identical or uniquely colored objects. Tracking was enhanced when objects were unique in color. The benefit was greater when the distance between distractors and targets was smaller, but was eliminated when the objects changed colors 1 to 4 times per second, even though at any instant they were always uniquely colored. Additionally, tracking uniquely colored objects impaired a secondary color-memory task more than tracking identical objects, and holding several colors in working memory eliminated the advantage of tracking uniquely colored objects. Contrary to previous studies showing that feature information is poorly retained during tracking, these findings indicate that surface properties are stored in visual working memory to facilitate tracking performance.
