Does attending to an option lead to liking it? Though attention-induced valuation is often hypothesized, evidence for this causal link has remained elusive. We test this hypothesis across 2 studies by manipulating attention during a preferential decision and its perceptual analog. In a free-viewing task, attention impacted choice and eye movement pattern in the preferential decision more than the perceptual analog. Similarly, in a controlled-viewing task, attention had a larger effect on choice in the preferential decision than its perceptual analog. Across these experimental manipulations of attention, choice and eye-tracking data provide converging evidence that attention enhances value, and computational modeling further supports this attention-induced valuation hypothesis. A possible explanation for our results is a normalization mechanism where attention induces a gain modulation on an option's representation at both the sensory and value processing levels.

关注一个选项会导致喜欢它吗？尽管注意力诱导的评估经常被假设，但这种因果关系的证据仍然难以捉摸。我们通过在偏好决策及其感知模拟中操纵注意力，在 2 项研究中检验了这一假设。在自由观看任务中，注意力对偏好决策中的选择和眼动模式的影响大于感知模拟。同样，在受控观看任务中，注意力对偏好决策中选择的影响大于其感知模拟。在这些注意力的实验操纵中，选择和眼动追踪数据提供了一致的证据，表明注意力增强了价值，计算模型进一步支持了这种注意力诱导的评估假设。我们结果的一个可能解释是归一化机制，其中注意力在感觉和价值处理水平上对选项的表示产生增益调制。（PsycInfo 数据库记录（c）2023 APA，保留所有权利）。
