Ten subjects were asked to pay attention to green or to red, when each visual stimulus was presented as two small squares, one green and the other red. They were instructed to push a button with the right hand, when the attended color was on the right side, and to push a button with the left hand, when the attended color was on the left side. The P1/N1 peak-to-peak amplitudes of visual event-related potentials were significantly higher when subjects focused attention on green rather than on red. We assume that the attended color had the effect of modulating the P1/N1 components.
当每个视觉刺激以两个小方块呈现时，一个绿色，另一个红色，十名受试者被要求注意绿色或红色。他们被指示，当所关注的颜色在右侧时用右手按按钮，当所关注的颜色在左侧时用左手按按钮。当受试者将注意力集中在绿色而不是红色上时，视觉事件相关电位的P1/N1峰峰值幅度显著更高。我们假设所关注的颜色具有调节P1/N1成分的作用。
