Abstract

We studied whether neon spreading can be induced within three-dimensional illusory triangles. Kanizsa triangles were induced by black pacman disks consisting of red sectors with curved sides. Viewing our stimuli monocularly produced two-dimensional illusory contours and surfaces as well as neon spreading in each figure. Triangles appeared concave or convex under stereoscopical viewing. Neon colour spreading was induced within illusory figures bending in three-dimensional space, suggesting that neural contour completion and surface filling-in interact across depth. Surprisingly, neon spreading was induced above the intervening surface even when the inducers were below the surface. Neon colour and illusory configuration were preserved behind the intervening surface only when it appeared transparent.

摘要

我们研究了在三维虚幻三角形内是否能诱发霓虹扩散效应。由带有弯曲边的红色扇形组成的黑色吃豆人圆盘诱发了卡尼兹三角形。单眼观察我们的刺激物会产生二维虚幻轮廓和表面，以及每个图形中的霓虹扩散效应。在立体观察下，三角形呈现出凹面或凸面。在三维空间中弯曲的虚幻图形内诱发了霓虹颜色扩散，这表明神经轮廓完成和表面填充在深度上相互作用。令人惊讶的是，即使诱导物在表面下方，霓虹扩散也会在中间表面上方诱发。只有当中间表面看起来透明时，霓虹颜色和虚幻构型才会保留在中间表面后面。
