注意力在决策中起什么作用？先前的研究已经证明视觉注意力和基于价值的选择之间存在联系，但因果关系的方向仍不清楚。在这里，我们的目的是证明注意力对选择有因果影响。我们测试了视觉搜索任务中的空间偏差注意力是否会在以后的选择任务中产生选择偏差。我们进行了四项实验，其中搜索目标更有可能出现在屏幕的“丰富”一侧。在随后的选择任务中，参与者更有可能选择出现在丰富一侧的项目，平均选择偏差取决于参与者对搜索任务中规律性的了解程度。此外，眼球追踪数据揭示了人们对富人的第一注视偏见，这反过来又影响了选择。总而言之，这些结果为注意力对选择的因果效应提供了新的支持。
What role does attention play in decision-making? Prior research has demonstrated a link between visual attention and value-based choice, but the direction of causality is still unclear. Here we aimed to demonstrate that attention has a causal influence on choice. We tested whether spatially biasing attention in a visual search task would produce choice biases in a later choice task. We ran four experiments where the search target was more likely to appear on one "rich" side of the screen. In the subsequent choice tasks, participants were more likely to choose items appearing on the rich side and the average choice bias depended on how well participants learned the regularity in the search task. Additionally, eye-tracking data revealed a first-fixation bias toward the rich side, which in turn influenced choices. Taken together, these results provide novel support for a causal effect of attention on choice.
