Several writers have hypothesized that the Mueller-Lyer illusion is influenced by brightness contrast between figure and background. According to them, lateral inhibition in the retina causes displacement in Mueller-Lyer figures at the intersections of lines. They argue that the strength of the displacement varies with brightness contrast between the background and the figure, and they cite research by Pollack and others for support. The experiments reported here show that the Mueller-Lyer illusion is no more affected by changes in contrast than are judgment of single straight lines. These results are not consistent with the view that lateral inhibition in the retina has an effect on the illusion.
几位作者推测，穆勒-莱尔错觉受图形与背景之间的亮度对比影响。据他们所说，视网膜中的侧向抑制会导致穆勒-莱尔图形在线条交叉处发生位移。他们认为，位移的强度随背景与图形之间的亮度对比而变化，并且他们引用了波拉克等人的研究作为支持。此处报告的实验表明，穆勒-莱尔错觉受对比度变化的影响并不比单一直线的判断更大。这些结果与视网膜中的侧向抑制对视错觉有影响这一观点不一致。
