It is well known that salient yet task irrelevant stimuli may capture our eyes independent of our goals and intentions. The present study shows that a task-irrelevant stimulus that is previously associated with high monetary reward captures the eyes much stronger than that very same stimulus when previously associated with low monetary reward. We conclude that reward changes the salience of a stimulus such that a stimulus that is associated with high reward becomes more pertinent and therefore captures the eyes above and beyond its physical salience. Because the stimulus capture the eyes and disrupts goal-directed behavior we argue that this effect is automatic not driven by strategic, top-down control.
众所周知，显著但与任务无关的刺激可能会不顾我们的目标和意图而吸引我们的目光。本研究表明，一个先前与高货币奖励相关联的与任务无关的刺激，比同一个刺激先前与低货币奖励相关联时更能强烈地吸引目光。我们得出结论，奖励改变了刺激的显著性，使得与高奖励相关联的刺激变得更具相关性，因此除了其物理显著性之外还能吸引目光。因为该刺激吸引目光并干扰目标导向行为，我们认为这种效应是自动的，而非由策略性的自上而下控制驱动。
