Considerable recent research in neurosciences has dealt with the topic of consciousness, even though there is still disagreement about how to identify and classify conscious states. Recent behavioral work on the topic also exists. We survey recent behavioral and neuroscientific literature with the aims of commenting on strengths and weaknesses of the literature and mapping new directions and recommendations for experimental psychologists. We reconcile this literature with a view of human information processing (Cowan, 1988; Cowan et al., 2024) in which a capacity-limited focus of attention is embedded within the activated portion of long-term memory, with dual bottom-up and top-down control of the focus of attention. None of the many extant theories fully captures what we propose as the organization of conscious thought at cognitive and neural levels. It seems clear that information from various cognitive functions, based on signals from various brain areas, is integrated into a conscious whole. In our new proposal, the integration involves funneling information to a hub or focus of attention neurally centered in the parietal lobes and functionally connected to areas representing the currently attended information. This funneling process (bringing information from diverse sensory and frontal sources to contact a small parietal area where attended information is coordinated and combined) may be the converse of global broadcasting, from other proposals (Baars et al., 2021; Baars & Franklin, 2003; Dehaene & Changeux, 2011). The proposed system incorporates many principles from previous research and theorization and strives toward a resolution of the relation between consciousness and attention.

尽管在如何识别和分类意识状态方面仍存在分歧,但神经科学领域最近有大量研究涉及意识这一主题。近期也有关于该主题的行为学研究。我们对近期的行为学和神经科学文献进行了综述,目的是评论这些文献的优缺点,并为实验心理学家规划新的方向和提出建议。我们将这些文献与一种人类信息处理观点(Cowan,1988;Cowan等人,2024)进行了协调,在这种观点中,注意力的容量受限焦点嵌入在长期记忆的激活部分内,对注意力焦点有自下而上和自上而下的双重控制。众多现存理论中没有一个能完全捕捉到我们所提出的认知和神经层面上有意识思维的组织方式。很明显,基于来自不同脑区的信号,来自各种认知功能的信息被整合为一个有意识的整体。在我们的新提议中,这种整合涉及将信息汇集到一个以顶叶为神经中心且在功能上与代表当前所关注信息的区域相连的注意力枢纽或焦点。这个汇集过程(将来自不同感觉和额叶来源的信息带到一个小的顶叶区域,在那里所关注的信息被协调和组合)可能与其他提议(Baars等人,2021;Baars & Franklin,2003;Dehaene & Changeux,2011)中的全局广播相反。所提出的系统纳入了先前研究和理论化中的许多原则,并努力解决意识与注意力之间的关系。(PsycInfo数据库记录(c)2025美国心理学会,保留所有权利)
