Two experiments examined college students' discrimination of complex visual displays that involved different degrees of variability or "entropy." Displays depicted 16 black and white line drawings of various types (e.g., a brain, a clock, a hand); the participants were required to classify a display in terms of its variability (e.g., a low-variability display contains many identical items, whereas a high-variability display contains few identical items). The participants' accuracy and reaction time scores on a 2-alternative forced-choice discrimination disclosed that people can and do use entropy to classify different levels of visual display variability. Individuals differed in their use of absolute rather than relative entropy.
两项实验研究了大学生对包含不同程度变异性或“熵”的复杂视觉显示的辨别能力。显示呈现了16种不同类型的黑白线条图（例如，大脑、时钟、手）；要求参与者根据其变异性对显示进行分类（例如，低变异性显示包含许多相同的项目，而高变异性显示包含很少相同的项目）。参与者在二选一强制选择辨别任务中的准确性和反应时间得分表明，人们能够且确实会利用熵来对不同水平的视觉显示变异性进行分类。个体在使用绝对熵而非相对熵方面存在差异。
