注意是重要或显著的刺激被选择用于知觉和认知加工的机制。哪些刺激被关注对有效的目标导向行为、生存和幸福有重要影响。越来越多的证据表明,奖励预测刺激会不自觉地吸引注意力。在以往的研究中,基于价值的注意优先性仅在先前与奖励相关的刺激本身被呈现为目标或干扰物时才被观察到。在这里,我们表明,刺激奖励协会在一个任务中学习推广到不同的刺激,共享一个定义功能(颜色)在另一个任务。我们的研究结果揭示了奖励学习在调节注意力优先方面的广泛而灵活的作用。
Attention is the mechanism by which important or salient stimuli are selected for perceptual and cognitive processing. Which stimuli are attended has important implications for effective goal-directed behaviour, survival, and well-being. A growing body of evidence suggests that reward-predicting stimuli capture attention involuntarily. In previous studies, value-based attentional priority has been observed only when the formerly reward-related stimuli themselves were presented as targets or distractors. Here we show that stimulus–reward associations learned in one task generalize to different stimuli that share a defining feature (colour) in another task. Our results reveal a broad and flexible role for reward learning in modulating attentional priority.
