Measures of illusion magnitude for a real contour and two subjective contour Poggendorff figures were obtained from a large number of dark-eyed and light-eyed undergraduates. Illusion magnitude varied as a function of figure type. However, eye color neither had a significant overall effect on illusion magnitude, nor did it interact with the figure-type variable. These data indicate that the presence of intersecting lines is not the basis of the iris-pigmentation effect reported by Coren and Porac.
从大量黑眼睛和浅眼睛的本科生中获得了真实轮廓以及两个主观轮廓波根多夫图形的错觉量度。错觉量度随图形类型而变化。然而,眼睛颜色对视错觉量度既没有显著的总体影响,也没有与图形类型变量产生交互作用。这些数据表明,相交线的存在并非科伦和波拉克所报道的虹膜色素沉着效应的基础。
