视觉注意被物理显著性刺激(称为基于显著性的注意捕获)和包含目标相关特征的与任务无关的刺激(称为偶然注意捕获)捕获。最近,我们报告说,通过奖励学习与价值相关的身体非显着刺激也会不自觉地捕获注意力(安德森,劳伦特,Yantis,PNAS,2011)。虽然它是已知的,身体显着性和目标相关性都影响注意优先,它是未知的是否或如何注意捕获的显着刺激调制其相关的价值。在这里,我们表明,一个物理上突出的,任务无关的干扰物以前与一个大的奖励减缓视觉搜索比一个同样突出的干扰物以前与一个较小的奖励。这种通过学习值来放大基于显著性的注意捕获的方法已经进行了数百次试验。这些发现揭示了学习价值对非自愿注意捕获的广泛影响。
Visual attention is captured by physically salient stimuli (termed salience-based attentional capture), and by otherwise task-irrelevant stimuli that contain goal-related features (termed contingent attentional capture). Recently, we reported that physically nonsalient stimuli associated with value through reward learning also capture attention involuntarily (Anderson, Laurent, & Yantis, PNAS, 2011). Although it is known that physical salience and goal-relatedness both influence attentional priority, it is unknown whether or how attentional capture by a salient stimulus is modulated by its associated value. Here we show that a physically salient, task-irrelevant distractor previously associated with a large reward slows visual search more than an equally salient distractor previously associated with a smaller reward. This magnification of salience-based attentional capture by learned value extinguishes over several hundred trials. These findings reveal a broad influence of learned value on involuntary attentional capture.
