受试者（年龄为 6、8、10、12 和 21 岁的小组，每组 60 人或以上）对单个圆圈和两侧有四个背景圆圈的标准圆圈进行大小比较判断。上下文圆的直径、与标准圆的接近程度以及显示的周长各不相同。 （当周长完成时，显示是通常的艾宾浩斯配置。一种变体由艾宾浩斯显示组成，其中每个背景圆周长的外部四分之三被删除。）轮廓加背景理论解释了数据：轮廓在每个年龄层都会吸引，而背景（侧翼圆相对于标准圆的大小）导致6岁以上判断尺寸的对比。轮廓和背景效果随着背景圆和标准圆之间的接近度的减小而减弱。
Subjects (groups of age 6, 8, 10, 12, and 21 years, with 60 or more persons per group) made comparative size judgments between a single circle and a standard circle that was flanked by four context circles. The context circles varied in diameter, proximity to the standard circle, and amount of circumference displayed. (When circumferences are complete, the display is the usual Ebbinghaus configuration. A variant consisted of the Ebbinghaus display with the outer three quarters of each context-circle circumference removed.) A contour-plus-context theory accounts for the data: Contours attract at every age level, and context (size of flanking circles relative to the standard circle) leads to constrast in judged size beyond age 6. Contour and context effects decreased with decreasing proximity between context circles and the standard circle.
