摘要

感知分组是我们视觉系统中的一种基本机制,它极大地影响着我们对周围世界的解读以及与周围世界的互动。本研究从两个视觉系统(TVS)模型的角度探讨了邻近原则的影响。双视觉系统模型认为,视觉系统包括两个不同的视觉流:构成 "感知视觉 "神经基础的腹侧视觉流和作为 "行动视觉 "基础的背侧视觉流。我们设计了一项使用点阵的感知分组任务和一项线方向辨别任务。在 "视觉-感知 "模式下,我们使用发声和鼠标方法收集数据;在 "视觉-行动 "模式下,我们使用操纵杆和纸笔方法收集数据。除发声方法外,每种方法都包括独立的左右手区块。接近度数据采用指数模型和幂模型进行拟合。线性混合效应模型用于统计分析。结果显示,所有条件下的线方向辨别准确率相似。指数模型的拟合效果最好,表明在两种感知模式下都符合纯距离定律。与 "视觉-感知 "模式相比,"视觉-行动 "模式对接近原则的敏感度更高。在方位偏差方面,"视觉换感知 "模式中对垂直方位有强烈偏好,而 "视觉换动作 "模式中对斜向方位有明显偏好。对自由画线的分析表明,在 "为行动而视觉 "模式下,人们会产生一种 "负担能力 "偏差。这表明,由于身体姿势和工具之间的相互作用,在特定方向上感知组织的趋势非常明显,这些方向提供了更多的可负担性。

Exploring perceptual grouping by proximity principle in multistable dot lattices: Dissociation between vision-for-perception and vision-for-action

Perceptual grouping, a fundamental mechanism in our visual system, significantly influences our interpretation of and interaction with the surrounding world. This study explores the impact of the proximity principle from the perspective of the Two Visual Systems (TVS) model. The TVS model argues that the visual system comprises two distinct streams: the ventral stream, which forms the neural basis for “vision-for-perception,” and the dorsal stream, which underlies “vision-for-action.” We designed a perceptual grouping task using dot lattices as well as a line-orientation discrimination task. Data were collected using vocal and mouse methods for the vision-for-perception mode, and joystick and pen-paper methods for the vision-for-action mode. Each method, except for vocal, included separate blocks for right and left hands. The proximity data were fitted using exponential and power models. Linear mixed-effects models were used for the statistical analyses. The results revealed similar line-orientation discrimination accuracy across all conditions. The exponential model emerged as the best fit, demonstrating adherence to the Pure Distance Law in both perceptual modes. Sensitivity to the proximity principle was higher in the vision-for-action mode compared to the vision-for-perception. In terms of orientation biases, a strong preference for vertical orientation was observed in the vision-for-perception mode, whereas a noticeable preference toward either of the oblique orientations was detected in the vision-for-action mode. Analysis of free-drawn lines demonstrated an affordance bias in the vision-for-action mode. This suggests a remarkable tendency to perceive organizations within specific orientations that offer more affordances due to the interaction between the body postures and tools.

期刊介绍: The journal Attention, Perception, & Psychophysics is an official journal of the Psychonomic Society. It spans all areas of research in sensory processes, perception, attention, and psychophysics. Most articles published are reports of experimental work; the journal also presents theoretical, integrative, and evaluative reviews. Commentary on issues of importance to researchers appears in a special section of the journal. Founded in 1966 as Perception & Psychophysics, the journal assumed its present name in 2009.
