知觉组织和选择性注意是影响我们如何感知视觉信息的两个关键过程。前者将复杂的视觉输入结构化为连贯的单元,而后者选择相关的信息。注意和知觉组织可以相互调节,影响视觉处理和各种任务和条件下的表现。在这里,我们测试了注意力是否可以改变多个元素的感知组织方式。我们操纵隐蔽空间注意使用快速串行视觉呈现任务,并测量知觉组织的两个多元素阵列的亮度相似性组织的行或列,在有人值守和无人值守的位置。我们发现,明显的知觉组织的多元阵列时,加强和衰减时,无人值守。我们排除了作为替代解释的反应偏差。这些发现表明,注意力增强了知觉组织的外观,这是一种中级视觉过程,改变了我们感知视觉环境的方式。
Perceptual organization and selective attention are two crucial processes that influence how we perceive visual information. The former structures complex visual inputs into coherent units, whereas the later selects relevant information. Attention and perceptual organization can modulate each other, affecting visual processing and performance in various tasks and conditions. Here, we tested whether attention can alter the way multiple elements appear to be perceptually organized. We manipulated covert spatial attention using a rapid serial visual presentation task, and measured perceptual organization of two multielements arrays organized by luminance similarity as rows or columns, at both the attended and unattended locations. We found that the apparent perceptual organization of the multielement arrays is intensified when attended and attenuated when unattended. We ruled out response bias as an alternative explanation. These findings reveal that attention enhances the appearance of perceptual organization, a midlevel vision process, altering the way we perceive our visual environment.
