In this research, the McCollough effect was observed by using an ambiguous test pattern of coarse gratings made out of fine gratings. Coarse gratings meet at right angles to fine gratings. The global features (coarse gratings) in the test pattern became more salient if the test pattern was blurred, and the frequency of the McCollough effect, corresponding to the global orientation of the test pattern, increased with the increase of the extent of blur. The McCollough effects corresponding to the local orientation of the test pattern occurred frequently if the subjects adapted to fine gratings before viewing the test pattern, whereas the McCollough effects corresponding to the global orientation of the test pattern occurred frequently if the subjects adapted to coarse gratings. Our results indicate that the perceptual organization is an important determinant in the McCollough effect.
在本研究中，通过使用由精细光栅构成的模糊粗光栅测试图案来观察麦考勒效应。粗光栅与精细光栅成直角相交。如果测试图案模糊，测试图案中的全局特征（粗光栅）会变得更加显著，并且与测试图案全局方向相对应的麦考勒效应频率会随着模糊程度的增加而增加。如果受试者在观看测试图案之前适应精细光栅，则与测试图案局部方向相对应的麦考勒效应会频繁出现，而如果受试者适应粗光栅，则与测试图案全局方向相对应的麦考勒效应会频繁出现。我们的结果表明，知觉组织是麦考勒效应的一个重要决定因素。
