摘要

在处理来自周围环境的视觉信息时,人类视觉依赖于形式和运动线索的不断整合。动态玻璃图案(GPs)可用于研究人类视觉系统如何进行这种视觉整合。动态玻璃图案是由两个或多个独特的框架组成的视觉刺激物,这些框架由不同配置的点对(称为偶极)组成,并快速连续地呈现。之前的心理物理研究表明,平移和环形动态 GP 的分辨能力受独特帧数和图案更新率的影响。在本研究中,我们操纵了这两个变量,以评估它们对圆形、径向和螺旋形 GP 的辨别阈值的影响,部分复制了之前对圆形 GP 的研究结果。我们的结果表明,圆形 GP 比径向和螺旋 GP 更容易被感知,显示出更低的辨别阈值。此外,我们还发现,辨别阈值会随独特帧数的变化而变化,但不会随图案更新率的变化而变化。具体来说,一致性阈值随着独特帧数的增加而降低。总之,我们的研究结果支持存在来自独特帧的形式信号的空间求和,从而产生复杂的 GP。另一方面,这些研究结果并不支持基于模式更新率的局部形体运动信号的时间整合。

Perception of complex Glass patterns through spatial summation across unique frames

When processing visual information from the surroundings, human vision depends on the constant integration of form and motion cues. Dynamic Glass patterns (GPs) may be used to study how such visual integration occurs in the human visual system. Dynamic GPs are visual stimuli composed of two or more unique frames consisting of different configurations of dot pairs, called dipoles, presented in rapid succession. Previous psychophysical studies showed that the discrimination of translational and circular dynamic GPs is influenced by both the number of unique frames and the pattern update rate. In this study, we manipulated these two variables to assess their influence on the discrimination threshold of circular, radial, and spiral GPs, partially replicating previous findings on circular GPs. Our results indicate that circular GPs are more easily perceived than radial and spiral GPs, showing lower discrimination thresholds. Furthermore, we found that discrimination thresholds vary as a function of the number of unique frames but not as a function of the pattern update rate. Specifically, coherence thresholds decreased with increasing the number of unique frames. In conclusion, our findings support the existence of spatial summation of form signals coming from the unique frames that generate complex GPs. On the other hand, they do not support temporal integration of local form-motion signals based on the pattern update rate.

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.
