我们研究了社会信息的神经处理变化作为社会排斥和攻击之间的可能联系。参与者与两个假定的游戏伙伴进行虚拟球类游戏，在此期间，34名参与者中有一半被排除在外。然后，参与者对同样的伙伴玩泰勒攻击范式（TAP）。接下来是移情模式，参与者观看中性和情绪化的社交场景的图片，同时进行功能磁共振成像（fMRI）。在与认知心智化和镜像神经元系统相关的区域（双侧颞上回、颞中回和颞下回、双侧楔前叶、右侧中央前回），被排除在外的参与者对情绪图片的神经反应强于被排除在外的参与者。左侧颞下回和右侧中央前回的反应性与攻击行为呈正相关。我们的研究结果支持了先前的行为研究结果，即社会信息加工的变化是排斥和攻击之间的中介。(C) 2013 Elsevier B.V.版权所有
We investigated changes in the neural processing of social information as possible link between social exclusion and aggression. Participants played a virtual ball game with two putative game partners, during which half of the 34 participants were excluded. Then, participants played the Taylor Aggression Paradigm (TAP) against the same partners. An empathy paradigm followed, in which participants watched pictures of neutral and emotional social scenes, while undergoing functional magnetic resonance imaging (fMRI). Excluded participants showed stronger neural reactivity to emotional compared to neutral pictures than included participants in regions associated with cognitive mentalizing and the mirror neuron system (bilateral superior, middle and inferior temporal gyrus, bilateral precuneus, right precentral gyrus). Reactivity of left inferior temporal gyrus and right precentral gyrus was positively correlated with aggressive behavior in the TAP. Our results support previous behavioral findings which suggest changes in social information processing as mediator between exclusion and aggression. (C) 2013 Elsevier B.V. All rights reserved.
