Binocular rivalry was examined with random dot patterns consisting of three colours: red, green and grey. The microstructure of the patterns was defined by the individual dots, and the correspondence between the microstructures in the two eyes was manipulated. The macrostructures were defined by the distributions of red, green and grey dots over the displays, so that they consisted of orthogonally striped patterns. The degree of correspondence between the microstructures was varied in Expt 1, together with the spatial frequency of the microstructure. Rivalry periods of the macrostructures were briefer when the microstructures were in correspondence, In Expt 2 the spatial frequencies of the macrostructures were varied. The lower spatial frequency predominated for longer than the higher. The results are discussed in terms of independent pathways for corresponding and rivalry stimulation. In addition a stimulus pairing that produces clear dichoptic colour mixtures is presented.
使用由红、绿、灰三种颜色组成的随机点图案来研究双眼竞争。图案的微观结构由单个点定义，并且两只眼睛中微观结构之间的对应关系被操控。宏观结构由显示屏上红、绿、灰点的分布定义，因此它们由正交条纹图案组成。在实验1中，微观结构之间的对应程度以及微观结构的空间频率都有所变化。当微观结构对应时，宏观结构的竞争期更短。在实验2中，宏观结构的空间频率发生变化。较低空间频率占主导的时间比高空间频率的更长。根据对应刺激和竞争刺激的独立通路对结果进行了讨论。此外，还呈现了一种能产生清晰双眼颜色混合的刺激配对。
