众所周知，光会引起非成像反应，例如对警觉性的影响。据报道，特别是在夜间暴露在光线下的时候。夜间结果可能无法转换为白天的结果。本文旨在提供一个概述(1)调节警觉性的神经机制，(2)测量和量化警觉性的方法，以及(3)当前的文献，特别是关于不同强度的白光对白天警觉性的各种测量和相关性的影响。总体而言，本文献提供了关于白天白光强度的警报效果的非决定性结果，特别是对于警报的客观测量和相关性。然而，早期研究中采用的各种研究范式有很大不同，大多数研究只测试了有限的一组照明条件。因此，暴露在更强烈的白光下的警报潜力应该以系统的、剂量依赖的方式进行研究，并在一天的过程中在一个实验范例内与警觉性的多种相关性进行研究。
Light is known to elicit non–image-forming responses, such as effects on alertness. This has been reported especially during light exposure at night. Nighttime results might not be translatable to the day. This article aims to provide an overview of (1) neural mechanisms regulating alertness, (2) ways of measuring and quantifying alertness, and (3) the current literature specifically regarding effects of different intensities of white light on various measures and correlates of alertness during the daytime. In general, the present literature provides inconclusive results on alerting effects of the intensity of white light during daytime, particularly for objective measures and correlates of alertness. However, the various research paradigms employed in earlier studies differed substantially, and most studies tested only a limited set of lighting conditions. Therefore, the alerting potential of exposure to more intense white light should be investigated in a systematic, dose-dependent manner with multiple correlates of alertness and within one experimental paradigm over the course of day.
