A growing body of evidence has demonstrated that multiple sources of salience tune attentional sets toward aspects of the environment, including affectively and motivationally significant categories of stimuli such as angry faces and reward-associated target locations. Recent evidence further indicates that objects that have gained personal significance through ownership can elicit similar attentional prioritization. Here we discuss current research on sources of attentional prioritization that shape our awareness of the visual world from moment to moment and the underlying neural systems and contextualize what is known about attentional prioritization of our possessions within that research. We review behavioral and neuroimaging research on the influence of self-relevance and ownership on cognition and discuss challenges to this literature stemming from different modes of conceptualizing and operationalizing the self. We argue that ownership taps into both "self-as-object," which characterizes the self as an object with a constellation of traits and attributes, and "self-as-subject," which characterizes the self as an agentic perceiver and knower. Despite an abundance of research probing neural and behavioral indices of self-as-object and its effects on attention, there exists a paucity of research on the influence of self-relevance of attention when self is operationalized from the perspective of a first-person subject. To begin to address this gap, we propose the Self as Ownership in Attentional Prioritization (SOAP) framework to explain how ownership increases salience through attention to external representations of self-identity (i.e., self as object) and attention to contextually mediated permission to act (i.e., self as subject).
越来越多的证据表明,多种显著性来源会将注意力集调整到环境的各个方面,包括情感上和动机上具有重要意义的刺激类别,如愤怒的面孔和与奖励相关的目标位置。最近的证据进一步表明,通过拥有而获得个人意义的物体可以引发类似的注意力优先级。在这里,我们讨论当前关于注意力优先级来源的研究,这些研究塑造了我们对视觉世界的瞬间感知,以及潜在的神经系统,并将关于我们财产的注意力优先级的已知信息置于该研究背景中。我们回顾了关于自我相关性和所有权对认知影响的行为和神经影像学研究,并讨论了由于对自我的不同概念化和操作化模式而给该文献带来的挑战。我们认为,所有权涉及“作为客体的自我”,它将自我表征为具有一系列特征和属性的客体,以及“作为主体的自我”,它将自我表征为有能动性的感知者和认知者。尽管有大量研究探究了作为客体的自我的神经和行为指标及其对注意力的影响,但从第一人称主体的角度对自我进行操作化时,关于自我相关性对注意力影响的研究却很少。为了开始填补这一空白,我们提出了注意力优先级中的自我即所有权(SOAP)框架,以解释所有权如何通过关注自我身份的外部表征(即作为客体的自我)和关注情境介导的行动许可(即作为主体的自我)来增加显著性。
