继先前对视觉掩蔽中的轮廓和亮度处理的研究(Breitmeyer 等人,2006)之后,我们研究了双眼和分视副对比掩蔽对呈现给另一只眼睛的目标轮廓和亮度的可见性的影响。综合起来,这些结果支持了几个皮质过程对副对比的贡献:(1)两个主要的抑制来源,一个是长潜伏期和延长的,另一个是短潜伏期和短暂的; (2)双眼竞争抑制; (3) 对于轮廓和亮度任务,反射在不同 SOA 处的促进效果达到峰值; (4)两个独立皮层系统的已知特性,一个是快速轮廓处理路径,另一个是较慢的亮度处理路径。
Following up on a prior study of contour and brightness processing in visual masking (Breitmeyer et al., 2006), we investigated the effects of a binocular and dichoptic para-contrast masking on the visibility of the contour and brightness of a target presented to the other eye. Combined, the results support the contributions of several cortical processes to para-contrast: (1) two central sources of inhibition, one long-latency and prolonged and the other short-latency and brief; (2) binocular rivalry suppression; and (3) a facilitatory effect peaking at different SOAs for the contour and the brightness tasks, reflecting; (4) known properties of two separate cortical systems, one a fast contour-processing pathway and the other a slower brightness-processing pathway.
