在处理自然场景的情感内容时，色彩是一个关键因素吗？在具有挑战性的感知条件下，例如当图片被短暂呈现时，颜色可以通过与场景相关的概念(例如，红色和血液/损伤)相关联来促进场景分割和/或用作语义提示。为了阐明颜色对情绪图片知觉的影响，我们比较了曝光时间很短(24ms)和较长时间(6 S)的彩色图片和灰度图片的晚期正电位。结果表明，去除颜色信息对LPP的情感调制没有影响，与暴露时间无关。这些发现表明，对场景的情感内容的识别，即使是非常简短的呈现，也并不严重地依赖于颜色信息。
Is color a critical factor when processing the emotional content of natural scenes? Under challenging perceptual conditions, such as when pictures are briefly presented, color might facilitate scene segmentation and/or function as a semantic cue via association with scene-relevant concepts (e.g., red and blood/injury). To clarify the influence of color on affective picture perception, we compared the late positive potentials (LPP) to color versus grayscale pictures, presented for very brief (24?ms) and longer (6?s) exposure durations. Results indicated that removing color information had no effect on the affective modulation of the LPP, regardless of exposure duration. These findings imply that the recognition of the emotional content of scenes, even when presented very briefly, does not critically rely on color information.
