本研究调查了平均物体尺寸的计算是基于感知尺寸还是基于物理尺寸。艾宾浩斯错觉被用来使一个圆的感知大小与它的实际大小不同。四种Ebbinghaus构型同时(实验1)或顺序(实验2)呈现给每个视野，参与者被指示只注意每个构型的中心圆圈。受试者对平均中心圆大小的判断受到艾宾浩斯错觉的影响。此外，艾宾浩斯错觉影响了个体大小的编码，而不是平均数。这些结果表明，在计算平均尺寸时，使用的是感知尺寸，而不是物理尺寸。
The present study investigated whether computation of mean object size was based on perceived or physical size. The Ebbinghaus illusion was used to make the perceived size of a circle different from its physical size. Four Ebbinghaus configurations were presented either simultaneously (Experiment 1) or sequentially (Experiment 2) to each visual field, and participants were instructed to attend only to the central circles of each configuration. Participants' judgments of mean central circle size were influenced by the Ebbinghaus illusion. In addition, the Ebbinghaus illusion influenced the coding of individual size rather than the averaging. These results suggest that perceived rather than physical size was used in computing the mean size.
