Certain psychophysical phenomena occur separately for color and for luminance stimulation. Separate psychophysical effects have also been elicited along different directions in equiluminant colour space. Whereas in most studies in which separate luminance and color effects have been reported the authors have used successive-adaptation approaches, less is known about the separateness of color and luminance processing under simultaneous conditions. A study is reported in which simultaneous size induction was examined for several different color directions thought to be 'cardinal' for early stages of processing. The perceived size of a test object was influenced by the size of the surrounding objects regardless of the color direction of the test and induction objects. The results indicate that simultaneous size induction occurs at a level of processing at which information conveyed by color and by luminance mechanisms is compared and contrasted to influence visual perception.
某些心理物理学现象在颜色和亮度刺激方面是分别发生的。在等亮度颜色空间中，沿着不同方向也引发了单独的心理物理学效应。尽管在大多数报告了单独亮度和颜色效应的研究中，作者使用了相继适应方法，但对于同时条件下颜色和亮度处理的分离性了解较少。本文报告了一项研究，其中针对几个被认为在处理早期阶段是“主要”的不同颜色方向，研究了同时性大小诱导。无论测试对象和诱导对象的颜色方向如何，测试对象的感知大小都受到周围对象大小的影响。结果表明，同时性大小诱导发生在一个处理水平上，在这个水平上，由颜色和亮度机制传达的信息被比较和对比，以影响视觉感知。
