我们使用双眼竞争作为心理物理探针来探索在方向、运动和颜色处理中的中心-周围相互作用。增加与竞争目标相匹配的环绕声极大地改变了竞争动态。对于所有的视觉子模态测试，优势的高对比度的竞争对手的目标相匹配的周围大大减少，结果消失在低对比度。在低对比度下，添加环绕增强了与环绕相匹配的方向和运动目标的优势。这种中心-环绕相互作用的对比度依赖性调制似乎是视觉系统的一般性质，并且可能反映了环绕抑制和空间求和之间的自适应平衡。(c)2005爱思唯尔有限公司保留所有权利。
Is We used binocular rivalry as a psychophysical probe to explore center-surround interactions in orientation, motion and color processing. Addition of the surround matching one of the rival targets dramatically altered rivalry dynamics. For all visual sub-modalities tested, predominance of the high-contrast rival target matched to the surround was greatly reduced-a result that disappeared at low contrast. At low contrast, addition of the surround boosted dominance of orientation and motion targets matched to the surround. This contrast-dependent modulation of center-surround interactions seems to be a general property of the visual system and may reflect an adaptive balance between surround suppression and spatial summation.
