Abstract

Mechanisms of object-based attention (OBA) are commonly associated with the cerebral cortex. However, less is known about the involvement of subcortical visual pathways in these processes. Knowledge of the neural mechanisms subserving OBA can provide insight into the evolutionary trajectory of attentional selection. In the current study, the classic double-rectangle cueing task was implemented using a stereoscope in order to differentiate between the involvement of lower (monocular) and higher (binocular) visual pathways in OBA processes. We found that monocular visual pathways are involved in two main aspects of OBA: exogenous orienting towards a cued object (Experiment 1; N =33) and attentional deployment within a cued object (Experiment 2; N =23); this is evident by the presence of OBA only when both the cue and target were presented to the same eye. Thus, these results indicate that monocular (mostly subcortical) visual regions are not simply passing information to higher cortical areas but have a functional computational role in OBA. These findings emphasize the importance of lower regions in attentional processes and, more specifically, in OBA.

基于物体的注意力需要单眼视觉通路。
基于物体的注意力(OBA)机制通常与大脑皮层有关。然而,人们对皮层下视觉通路在这些过程中的参与知之甚少。了解 OBA 的神经机制可以帮助人们了解注意选择的进化轨迹。在当前的研究中,为了区分低级(单眼)和高级(双眼)视觉通路在 OBA 过程中的参与情况,我们使用立体镜执行了经典的双矩形提示任务。我们发现,单眼视觉通路参与了OBA的两个主要方面:对提示对象的外源定向(实验1;N =33)和在提示对象内的注意调配(实验2;N =23);只有当提示和目标都呈现在同一只眼睛上时,才会出现OBA,这一点非常明显。因此,这些结果表明,单眼(主要是皮层下)视觉区域并不是简单地向高级皮层区域传递信息,而是在 OBA 中起着功能性计算作用。这些发现强调了低级区域在注意过程中的重要性,更具体地说,是在OBA中的重要性。

期刊介绍: The journal provides coverage spanning a broad spectrum of topics in all areas of experimental psychology. The journal is primarily dedicated to the publication of theory and review articles and brief reports of outstanding experimental work. Areas of coverage include cognitive psychology broadly construed, including but not limited to action, perception, & attention, language, learning & memory, reasoning & decision making, and social cognition. We welcome submissions that approach these issues from a variety of perspectives such as behavioral measurements, comparative psychology, development, evolutionary psychology, genetics, neuroscience, and quantitative/computational modeling. We particularly encourage integrative research that crosses traditional content and methodological boundaries.
