之前对艺术中知觉偏差的研究表明，绘画倾向于从上方和左侧照明。抽象图像提供了一种测试左光偏差的方法，同时控制诸如姿势偏差、地线、阴影和反射等线索。共有42名参与者完成了一项任务，这项任务需要在电脑屏幕上呈现的抽象图像的表面上移动一支“虚拟手电筒”：研究中使用了20张图像(倒置和倒置两种图像)。参与者唯一的指示就是“以最美观的方式点亮这幅画”。正如预测的那样，参与者平均将“虚拟手电筒”聚焦在左上角象限。这项研究表明，艺术品中的侧向照明偏差不依赖于对局部光源的感知，也不依赖于与艺术品中离散的、具体的视觉表现的相互作用。
Previous studies examining perceptual biases in art have revealed that paintings tend to be lit from above and to the left. Abstract images provide a way of testing for the left-light bias while controlling for cues such as posing biases, ground line, shadows, and reflections. A total of 42 participants completed a task that required moving a “virtual flashlight” across the surface of abstract images presented on a computer screen: 20 images (presented both right-side-up and upside down) were used in the study. The participant's only instruction was to “light the painting in a way that is most aesthetically pleasing to you”. As predicted, participants on average focused the “virtual flashlight” in the top left quadrant. This study reveals that lateral lighting biases in artwork are not dependent on perception of local light source or interactions with discrete, concrete visual representations in the artwork.
