Proactive aggression can result in many economic, social, and health problems. It has two levels: trait and state. Although the neural basis of trait proactive aggression is becoming clearer, the neural basis of state proactive aggression has been largely ignored and remains unclear.
We explore the basic brain correlates of state proactive aggression using a reward-interference task (RIT), in which participants play a competitive reactive time task against an opponent. They can make decision to give the opponent noise interference for winning the game and gaining reward or not. Forty healthy participants from a university in China performed the RIT in the scanner and their functional images were obtained on a 3.0-T Siemens Tim Trio scanner. Finally, 38 participants (21 males, M age = 19.24, SD = 1.32) were included in analyses.
The results show that relative to the baseline, the medial prefrontal cortex (MPFC), anterior cingulate cortex (ACC), temporoparietal junction (TPJ), and inferior frontal gyrus (IFG) were activated by aggression selection and nonaggression selection in the RIT. Furthermore, relative to nonaggression selection, the MPFC, ACC, TPJ, IFG, middle cingulate cortex (MCC), and middle temporal gyrus (MTG) were more strongly activated during aggression selection and correlated with the scores of some of the three basic proactive aggression motivations (instrumental motivation, moral inhibition motivation, and moral approval motivation).
The results provide preliminary evidence of neural correlates for state proactive aggression and should be replicated by other methods or with other samples. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
积极进取的攻击性可能会导致许多经济、社会和健康问题。它有两个层次：特质和状态。尽管特质积极进取的攻击性的神经基础变得越来越清晰，但状态积极进取的攻击性的神经基础在很大程度上被忽视了，仍然不清楚。
我们使用奖励干扰任务（RIT）来探索状态积极进取的攻击性的基本大脑相关性，在该任务中，参与者与对手进行竞争性反应时间任务。他们可以做出决定，给对手噪音干扰以赢得游戏并获得奖励，或者不这样做。来自中国一所大学的 40 名健康参与者在扫描仪中执行了 RIT，他们的功能图像是在西门子 Tim Trio 3.0-T 扫描仪上获得的。最后，38 名参与者（21 名男性，M 年龄=19.24，SD=1.32）被纳入分析。
结果表明，与基线相比，在 RIT 中，内侧前额叶皮层（MPFC）、前扣带皮层（ACC）、颞顶联合区（TPJ）和下额回（IFG）被攻击性选择和非攻击性选择激活。此外，与非攻击性选择相比，在攻击性选择期间，MPFC、ACC、TPJ、IFG、中扣带皮层（MCC）和中颞回（MTG）被更强烈地激活，并且与三种基本积极进取的攻击性动机（工具动机、道德抑制动机和道德认可动机）的一些分数相关。
这些结果为状态积极进取的攻击性的神经相关性提供了初步证据，应通过其他方法或其他样本进行复制。（PsycInfo 数据库记录（c）2022 APA，保留所有权利）。
