There has been considerable interest in a stimulus ("the dress") that yields starkly divergent subjective color percepts between observers. It has been proposed that individual differences in the subjective interpretation of this stimulus are due to the different assumptions that individuals make about how the dress was illuminated. In this study, we address this possible explanation empirically by reporting on data from ∼13,000 observers who were surveyed online. We show that assumptions about the illumination of the dress-i.e., whether the stimulus was illuminated by natural or artificial light or whether it was in a shadow-strongly affects the subjective interpretation of observers, compared to demographic factors, such as age or gender, which have a relatively smaller influence. We interpret these findings in a Bayesian framework by also showing that prior exposure to long- or short-wavelength lights due to circadian type shapes the subjective experience of the dress stimulus in theoretically expected ways.

人们对刺激 (“着装”) 产生了极大的兴趣,这种刺激在观察者之间产生了明显不同的主观色彩感知。有人提出,这种刺激的主观解释中的个体差异是由于个体对衣服的照明方式的不同假设所致。在这项研究中,我们通过报告来自在线调查的约13,000名观察员的数据,以经验方式解决了这一可能的解释。我们表明,关于dress-i.e照明的假设,无论刺激是由自然光还是人造光照射,还是在阴影中,都强烈影响观察者的主观解释,与年龄或性别等人口统计学因素相比,影响相对较小。我们在贝叶斯框架中解释了这些发现,还表明由于昼夜节律类型而预先暴露于长波或短波长光中以理论上预期的方式塑造了着装刺激的主观体验。
