虽然亮度的增加和减少在视觉科学中是一个相当著名的研究领域，但大多数工作都集中在快速变化的刺激(闪烁)或静态阈值测量上。人们对缓慢变化的刺激的视觉处理知之甚少。所描述的工作集中于亮度缓慢降低的检测阈值的测量，该检测阈值低于可将波动称为闪烁的频率。实验研究表明，对于所使用的亮度降低率范围，检测阈值产生一个恒定值。此外，该值不受检测过程中精神分心的存在的影响。
Although the increments and decrements in luminance are a fairly well researched and known area in vision science, most of the work has been focused on fast changing stimuli (flicker) or static threshold measurements. Notmuch is known about visual processing of slow-changing stimuli. The described work focuses on measurements of detection threshold for slow reduction of luminance, below the frequencies at which the fluctuations may be referred to as flicker. The experimental study shows that for the used range of luminance reduction rates the detection threshold yields a constant value. Additionally, this value is not influenced by the presence of mental distraction during the detection process.
