An adequate account of the phenomena of illusory contours (ICs) will require an understanding of the genesis of such effects. There are two main techniques used to study perceptual genesis: the first is to slow down the relevant perceptual processes and to study them during perceptual learning; the second employs tachistoscopic exposures and backward masking. To date the technique of perceptual learning has not been shown to be applicable in the case of ICs. Two experiments are reported in which perceptual learning is used to study ICs. It is demonstrated that subjects can learn to see, first, illusory contours and, second, illusory colour. The suggestion is made that although there may be different kinds of illusory phenomena which may arise in different ways, these may all depend upon a common set of mechanisms.
要充分解释错觉轮廓（ICs）现象，就需要理解此类效应的成因。研究知觉成因主要有两种技术：第一种是放慢相关的知觉过程，并在知觉学习过程中对其进行研究；第二种采用速示曝光和后向掩蔽。到目前为止，尚未证明知觉学习技术适用于错觉轮廓的情况。本文报告了两项利用知觉学习来研究错觉轮廓的实验。结果表明，受试者能够学会看到，首先是错觉轮廓，其次是错觉颜色。有人提出，尽管可能存在以不同方式出现的不同种类的错觉现象，但这些现象可能都依赖于一组共同的机制。
