Many studies have proved that color represents a variety of emotionally meaningful information. Researchers have proposed that context information endows colors with different associated meanings, and elicits corresponding behavior. Others have contended that the color red intensifies the stimulus' existing valence or motivation tendency in the early processing step. The present study attempts to incorporate these two effects of the color red to explore their differences in a dot probe task, using event-related potential (ERP). Our ERP results indicate that the color red intensifies the initial attention to emotion-congruent conditions, as indicated by the P1 component. However, the colors red and green lead to sustained attention to the expression of anger and happiness, respectively, but not fear, as shown by the late positive complex component (all results are available at: https://osf.io/k3b8c/). This study found the different processing stages of the effect of the color red during attentional processing in a discrete emotional context, using ERPs, and may refine the Color-in-Context theory.
许多研究已经证明，颜色代表着各种具有情感意义的信息。研究人员提出，情境信息赋予颜色不同的关联意义，并引发相应的行为。其他人则认为，红色在早期加工阶段会强化刺激的现有效价或动机倾向。本研究试图将红色的这两种效应结合起来，利用事件相关电位（ERP）在点探测任务中探究它们的差异。我们的ERP结果表明，如P1成分所示，红色会增强对情绪一致条件的初始注意力。然而，晚期正复合波成分显示，红色和绿色分别导致对愤怒和快乐表情的持续关注，但对恐惧表情则不然（所有结果可在：https://osf.io/k3b8c/获取）。本研究利用ERP在离散情绪情境中发现了红色效应在注意力加工过程中的不同处理阶段，可能会完善情境中的颜色理论。
