长期以来，人们都知道视觉注意力会被物理上显着的或与特定任务目标一致的刺激所吸引。最近的几项研究表明，注意力也会被既不显着也不与任务相关的刺激所吸引，而是以以前与奖励相关的颜色呈现。我们研究了另一个特征维度——方向——是否可以通过学习与奖励相关联，从而引发价值驱动的注意力捕获。在训练阶段，参与者因识别显示两个目标方向之一的 Gabor 斑块的颜色而获得金钱奖励。随后的测试阶段不提供任何奖励，要求参与者搜索表现出两个空间频率之一的 Gabor 斑块（方向现在与任务无关）。之前的奖励方向吸引了人们的注意。我们的结论是，奖励学习可以为颜色以外的特征（在本例中为特定方向）赋予持久价值。
Visual attention has long been known to be drawn to stimuli that are physically salient or congruent with task-specific goals. Several recent studies have shown that attention is also captured by stimuli that are neither salient nor task-relevant, but that are rendered in a color that has previously been associated with reward. We investigated whether another feature dimension—orientation—can be associated with reward via learning and thereby elicit value-driven attentional capture. In a training phase, participants received a monetary reward for identifying the color of Gabor patches exhibiting one of two target orientations. A subsequent test phase in which no reward was delivered required participants to search for Gabor patches exhibiting one of two spatial frequencies (orientation was now irrelevant to the task). Previously rewarded orientations robustly captured attention. We conclude that reward learning can imbue features other than color—in this case, specific orientations—with persistent value.
