摘要

背景:本研究探讨了视觉知觉中强调与注意之间的复杂关系,扩展了经典格式塔原理,引入了知觉组织中不相似性作为相似性的补充机制。目的与方法:通过一系列的现象学实验,我们证明了由不相似性驱动的强调如何在形成视觉经验和引导注意力方面发挥关键作用。结果:我们的研究结果表明,在突出显著特征、影响初始知觉组织和调节视觉元素的表观形状和方向方面,加重是一种前注意机制。我们的研究表明,虽然强调快速而自动地进行,但注意力作为一种灵活的选择性机制,可以加强或推翻基于强调的感知。这种相互作用表明了视觉感知的两阶段过程,对生物系统中的意识和信息处理理论具有启示意义。本研究还探讨了伪装和性选择中强化的进化意义,为感知机制如何进化以增强适应性提供了见解。结论:我们的研究结果对理解视觉认知、设计和与注意力障碍相关的临床应用具有广泛的意义。

Accentuation and Attention: From Perceptual Organization to Consciousness.

Background: This study investigates the complex relationship between accentuation and attention in visual perception, extending classical Gestalt principles by introducing dissimilarity as a complementary mechanism to similarity in perceptual organization. Objectives and Methods: Through a series of phenomenological experiments, we demonstrate how accentuation, driven by dissimilarity, plays a crucial role in shaping visual experience and guiding attention. Results: Our findings reveal that accentuation serves as a pre-attentive mechanism for highlighting salient features, influencing initial perceptual organization, and modulating the apparent shape and orientation of visual elements. We show that while accentuation operates rapidly and automatically, attention acts as a flexible, selective mechanism that can either reinforce or override accentuation-based percepts. This interplay suggests a two-stage process of visual perception, with implications for theories of consciousness and information processing in biological systems. This study also explores the evolutionary significance of accentuation in camouflage and sexual selection, providing insights into how perceptual mechanisms may have evolved to enhance adaptive fitness. Conclusions: Our results have broad implications for understanding visual cognition, design, and clinical applications related to attentional disorders.

期刊介绍: Brain Sciences (ISSN 2076-3425) is a peer-reviewed scientific journal that publishes original articles, critical reviews, research notes and short communications in the areas of cognitive neuroscience, developmental neuroscience, molecular and cellular neuroscience, neural engineering, neuroimaging, neurolinguistics, neuropathy, systems neuroscience, and theoretical and computational neuroscience. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
