Attention, an important index of cognitive function, can be affected amidst colored lights. This work investigated the effects of colored lights on the performance in attention task. Participants (N = 42) performed in one, two, and three letter cancellation task (LCT) during four lighting conditions. The order of LCT and the colored light sessions were randomized. The performance in LCT was evaluated through % accuracy, % omission, and % error. A repeated measures ANOVA showed a statistically significant difference in % accuracy in one LCT (F(2.46, 100.8) = 24.45, p < 0.001), two LCT (F(2.57, 105.4) = 20.53, p < 0.001), and three LCT (F(2.66, 109.22) = 17.96, p < 0.001) among the four colored lights. In addition, % omission revealed a statistically significant difference in one LCT (F(2.46, 100.8) = 24.43, p < 0.001), two LCT (F(2.57, 105.4) = 20.57, p < 0.001), and three LCT (F(2.66, 109.16) = 18.21, p < 0.001) among the four lights. There was no statistically significant difference in % error in one LCT (F(2.05, 84.1) = 1.23, p = 0.3), two LCT (F(2.66, 109.06) = 0.62, p = 0.971), three LCT (F(2.62, 107.53) = 0.97, p = 0.4) among the four lighting conditions. Colored lights affect attention-related cognitive processing. The attentional correlates of white and red lights are more compared to green, and blue lights. Lighting condition should be an important consideration for cognitive testing, for designing workspaces, educational settings, and other environments where attention plays a crucial role.
注意是认知功能的一个重要指标，它可能会受到彩色灯光的影响。本研究旨在探讨彩色灯光对注意力任务表现的影响。42 名参与者在四种照明条件下完成了一次、两次和三次字母删除任务（LCT）。LCT 和彩色灯光的顺序是随机的。通过 %准确性、%遗漏和%错误来评估 LCT 中的表现。重复测量方差分析显示，在四种颜色的灯光中，一次 LCT（F(2.46, 100.8) = 24.45, p < 0.001）、两次 LCT（F(2.57, 105.4) = 20.53, p < 0.001）和三次 LCT（F(2.66, 109.22) = 17.96, p < 0.001）的%准确性存在统计学上的显著差异。此外，%遗漏在一次 LCT（F(2.46, 100.8) = 24.43, p < 0.001）、两次 LCT（F(2.57, 105.4) = 20.57, p < 0.001）和三次 LCT（F(2.66, 109.16) = 18.21, p < 0.001）中存在统计学上的显著差异。在一次 LCT（F(2.05, 84.1) = 1.23, p = 0.3）、两次 LCT（F(2.66, 109.06) = 0.62, p = 0.971）和三次 LCT（F(2.62, 107.53) = 0.97, p = 0.4）中，%错误没有统计学上的显著差异。彩色灯光会影响与注意力相关的认知加工。与绿光和蓝光相比，白光和红光的注意力相关性更强。在认知测试、工作空间设计、教育环境等注意力起着关键作用的环境中，照明条件应该是一个重要的考虑因素。
