The vital role of reward in guiding visual attention has been supported by previous literatures. Here we examined the motivational impact of monetary reward feedback stimuli on visual attention selection using an Event-related potential (ERP) component called stimulus preceding negativity (SPN) and a standard contextual cueing paradigm. It has been proposed that SPN reflects affective and motivational processing. We focused on whether incidentally learned context knowledge could be affected by reward. Both behavior and brain data demonstrated that contexts followed by reward feedback not only gave rise to faster implicit learning, but also obtained larger contextual cueing effect (CC).

金钱奖励促进并增强了语境提示：来自与事件相关的脑潜能的证据

奖励在引导视觉注意力方面的重要作用已得到先前文献的支持。在这里，我们使用称为“事前消极刺激”（SPN）的事件相关电位（ERP）组件和标准的上下文提示范式，研究了金钱奖励反馈刺激对视觉注意选择的动机影响。已经提出，SPN反映了情感和动机过程。我们关注的是偶然学习的情境知识是否会受到奖励的影响。行为和大脑数据都表明，情境和奖励反馈不仅能带来更快的内隐学习，而且还能获得更大的情境提示效果（CC）。
