The experiment of Dresp and Bonnet [(1991) Vision Research, 31, 1813-1817] was replicated and extended to include measurements of both luminance increment and decrement detection across high luminance illusory contours. The results reveal that illusory contours can influence the detectability of both luminance decrements and increments and, in addition, that the magnitude and even the direction of the effect which illusory contours produce on visual thresholds may vary considerably across individual observers. Finally, in contrast to the monophasic pattern of threshold variation across low luminance illusory contours, the pattern across high luminance contours is oscillatory.
德雷斯普和博内特（1991年，《视觉研究》，第31卷，第1813 - 1817页）的实验被重复并扩展，以纳入对高亮度虚幻轮廓上亮度增加和减少检测的测量。结果表明，虚幻轮廓可以影响亮度减少和增加的可检测性，此外，虚幻轮廓对视觉阈值产生的影响的大小甚至方向在个体观察者之间可能有很大差异。最后，与低亮度虚幻轮廓上阈值变化的单相模式相反，高亮度轮廓上的模式是振荡的。
