摘要

理解别人的注意力是人际交往的核心。当我们察觉到某件事引起了别人的注意时,我们就会理解它此刻在那个人的脑海里,准备好影响那个人的选择。有人提出,人们会构建他人注意状态的预测模型。在这个提议中,对他人注意力的有效理解远远超出了仅仅追踪某人眼睛的方向。例如,在最近的一项研究中,参与者观察一个注意力焦点在一张图片上移动,并成功判断出这个痕迹是真实的、人类的注意力,还是人为操纵的,从而展示了关于注意力模式如何随时间和空间变化的隐含信息。然而,注意力建模的神经元基础几乎完全没有被研究过。在这里,我们用fMRI扫描仪对人们进行测试,同时让他们进行注意力判断范式。当将参与者判断为人为的注意力痕迹与判断为真实的注意力痕迹进行对比时,在双侧楔前叶、背内侧前额叶皮层、前扣带、前岛以及右侧颞顶交界处的一部分都发现了活动。这些区域部分重叠了心理理论网络和显著性网络。这些激活不同于那些已知涉及处理低级注意力特征的激活,比如看到别人的眼睛。研究结果提供了大脑皮层网络的初步图像,这些网络参与监控他人的注意力模式,并识别这些模式何时偏离预期。

Cortical networks involved in judging the attention of others.

Understanding someone else's attention lies at the heart of human interaction. When we perceive something to be in someone else's attention, we understand it to be in that person's mind in the moment, ready to affect that person's choices. It has been proposed that people construct predictive models of the attentional state of others. In that proposal, a working understanding of someone else's attention goes far beyond merely tracking the direction of someone's eyes. For example, in a recent study, participants watched a spotlight of attention moving around a picture and successfully judged whether the trace represented real, human attention or an artificially manipulated version, demonstrating implicit information about how patterns of attention behave over space and time. However, the neuronal underpinnings of attention modeling are almost entirely unstudied. Here we tested people in an fMRI scanner while they performed the attention judgment paradigm. When contrasting attention traces that participants judged to be artificial versus those judged to be real, activity was found bilaterally in the precuneus, dorsomedial prefrontal cortex, anterior cingulate, and anterior insula, as well as in a part of the right temporoparietal junction. These areas partially overlap the theory-of-mind network and the salience network. The activations differ from those known to be involved in processing low-level features of attention such as the sight of other people's eyes. The results provide an initial picture of the cortical networks involved in monitoring the attention patterns of others and recognizing when those patterns deviate from expectation.

期刊介绍: Cerebral Cortex publishes papers on the development, organization, plasticity, and function of the cerebral cortex, including the hippocampus. Studies with clear relevance to the cerebral cortex, such as the thalamocortical relationship or cortico-subcortical interactions, are also included. The journal is multidisciplinary and covers the large variety of modern neurobiological and neuropsychological techniques, including anatomy, biochemistry, molecular neurobiology, electrophysiology, behavior, artificial intelligence, and theoretical modeling. In addition to research articles, special features such as brief reviews, book reviews, and commentaries are included.
