描述了一种新的视觉现象,我们称之为闪烁异常色彩对比。这种现象是由灰色的中央圆盘和被黑色径向线包围的彩色环之间的相互作用引起的。在一组这样的图像中,中心的灰色圆盘不再是灰色的,而是与周围环的颜色互补。产生的色彩表现为:(1)鲜艳、饱和;(2)自发光,无表面特性;(3)伴有眼球或刺激运动的闪光;(四)浮出其范围的;(5)中央凹外视力强于中央凹视力。效果的强度取决于径向线的数量、长度、宽度和亮度对比。结果表明,包围黑色径向线内尖端的彩色环引起了同时的色彩对比,而径向线与灰色圆盘和环一起引起了闪烁、生动和高饱和度的效果。诱发幻觉的刺激特性表明,闪烁的异常颜色对比可能是基于多种视觉通路之间的异步相互作用。
A new visual phenomenon that we call flashing anomalous color contrast is described. This phenomenon arises from the interaction between a gray central disk and a chromatic annulus surrounded by black radial lines. In an array of such figures, the central gray disk no longer appears gray, but assumes a color complementary to that of the surrounding annulus. The induced color appears: (1) vivid and saturated; (2) self-luminous, not a surface property; (3) flashing with eye or stimulus movement; (4) floating out of its confines; and (5) stronger in extrafoveal than in foveal vision. The strength of the effect depends on the number, length, width, and luminance contrast of the radial lines. The results suggest that the chromatic ring bounding the inner tips of the black radial lines induces simultaneous color contrast, whereas the radial lines elicit, in conjunction with the gray disk and the ring, the flashing, vividness, and high saturation of the effect. The stimulus properties inducing the illusion suggest that flashing anomalous color contrast may be based on asynchronous interactions among multiple visual pathways.
