Abstract

Interocular grouping during binocular rivalry occurs when two images presented to each eye combine into a coherent pattern. The experience of interocular grouping is thought to be influenced by both eye-of-origin, which involves excitatory lateral connections among monocular neurons, and pattern coherence, which results from top-down intervention from higher visual areas. However, it remains unclear which factor plays a more significant role in the interocularly-grouped percepts during binocular rivalry. The current study employed an individual difference approach to investigate whether grouping dynamics are mainly determined by eye-of-origin or pattern coherence. We found that participants who perceived interocularly-driven coherent percepts for a longer duration also tended to experience longer periods of monocularly-driven coherent percepts. In contrast, participants who experienced non-coherent piecemeal percepts for an extended duration in conventional rivalry also had longer duration of non-coherent percepts in the interocular coherence setting. This individual differences in experiencing interocular grouping suggest that pattern coherence exerts a stronger influence on grouping dynamics during binocular rivalry compared to eye-of-origin factors.

双目对视时模式连贯性在眼间分组中的作用:个体差异的启示
当呈现在每只眼睛上的两幅图像组合成一个连贯的图案时,就会发生双眼对抗时的眼间分组。眼间分组的体验被认为受到两个因素的影响,一个是眼源因素(涉及单眼神经元之间的兴奋性侧向连接),另一个是模式一致性因素(来自高级视觉区域的自上而下的干预)。然而,目前还不清楚哪种因素在双眼对抗时的眼间分组知觉中起着更重要的作用。本研究采用了个体差异的方法来研究分组动态是否主要由起源眼或模式一致性决定。我们发现,感知眼间驱动的一致性知觉持续时间较长的参与者往往也会经历较长时间的单眼驱动的一致性知觉。与此相反,在传统对抗中经历了较长时间非一致性零散知觉的参与者,在眼间一致性环境中也有较长时间的非一致性知觉。这种体验眼间分组的个体差异表明,与眼源因素相比,模式相干性对双眼对抗过程中的分组动态影响更大。

期刊介绍: Vision Research is a journal devoted to the functional aspects of human, vertebrate and invertebrate vision and publishes experimental and observational studies, reviews, and theoretical and computational analyses. Vision Research also publishes clinical studies relevant to normal visual function and basic research relevant to visual dysfunction or its clinical investigation. Functional aspects of vision is interpreted broadly, ranging from molecular and cellular function to perception and behavior. Detailed descriptions are encouraged but enough introductory background should be included for non-specialists. Theoretical and computational papers should give a sense of order to the facts or point to new verifiable observations. Papers dealing with questions in the history of vision science should stress the development of ideas in the field.
