Abstract

We report a new illusion in which the edges of diamonds placed at the intersections of grids are perceived to be jaggy (the jaggy diamonds illusion). Interestingly, the illusion disappears when the stimulus is rotated by 45 degrees, when the stimuli are observed at a close distance, and on the diamond at which the observers stare. Luminance contrast between diamonds, grids, and background is a strong determinant for this illusion.

摘要

我们报告了一种新的错觉，即置于网格交点处的菱形边缘会被感知为锯齿状（锯齿菱形错觉）。有趣的是，当刺激物旋转45度、在近距离观察刺激物时以及在观察者注视的菱形上时，这种错觉会消失。菱形、网格和背景之间的亮度对比度是这种错觉的一个重要决定因素。
