我们研究了视觉搜索的颜色单例目标，其形状是歧视。重要的是，我们改变了单一颜色的奖励优先级（红色单一的正确快速性能比绿色单一值得更多的“奖励点”，反之亦然），同时测试ERP签名的视觉选择是否会受到不同的奖励优先级为不同的目标类型，即使每个目标都必须选择报告。N2pc的组成部分是更早和更大的高回报与低回报的目标。这种奖励对N2PC的影响与奖励水平对行为表现效率的影响相关。目标奖励水平也会影响后期选择后加工。这些结果表明，即使必须选择两种类型的目标进行响应，任务相关项目的视觉选择也会迅速受到奖励相关优先级的调节。
We examined visual search for color singleton targets, whose shape was discriminated. Critically, we varied the reward priority of singleton colors (correct fast performance for red singletons was worth more “bonus points” than for green singletons, or vice-versa), while testing whether ERP signatures of visual selection can be affected by distinct reward priorities for different target types, even when every target has to be selected for report. The N2pc component was earlier and larger for high- versus low-reward targets. This reward influence on the N2pc correlated with the subject-by-subject impact of reward level on efficiency of behavioral performance. Later post-selection processing was also affected by target reward-level. These results demonstrate that visual selection of task-relevant item is rapidly modulated by reward-related priorities, even when both types of target have to be selected for response.
