Abstract

One-dimensional visual lobes representing the detectability of a small bright target on an unstructured background were measured at several contrast levels, both with and without an artificial foveal scotoma. The effect of the scotoma on the lobe is shown to be restricted to the area of the retina covered by the scotoma, and detection ability is unaffected outside this area.

摘要

在有无人工中心凹暗点的情况下，于多个对比度水平测量了代表在无结构背景上小的明亮目标可检测性的一维视觉叶。结果表明，暗点对视觉叶的影响仅限于暗点覆盖的视网膜区域，该区域之外的检测能力不受影响。
