To investigate the contribution of agency to neural processing involved in aggression and morality, participants viewed in the MRI scanner a series of short visual scenarios in which an individual was either intentionally harming another person or easing the other's pain. They were required to mentally simulate being the perpetrator or the recipient of those actions. Functional connectivity analyses demonstrate that positive agency (easing the pain of another) was associated with increased activity in ventral striatum, while negative agency (harming the other) resulted in a strong signal decrease in the ventromedial prefrontal cortex and activation in the amygdala. Overall, our data show that explicit perspective taking strategy has profound impact on the neural recruitment associated with distinct behaviors as well as their moral consequences. Results from this study can inform new strategies both for therapeutic interventions for patients with socioemotional disorders and the education of medical practitioners.
为了探究主体在攻击性和道德性神经加工中的作用,参与者在磁共振成像扫描仪中观看了一系列简短的视觉场景,场景中个体要么故意伤害他人,要么减轻他人的痛苦。他们需要在心理上模拟自己是这些行为的实施者或受害者。功能连接分析表明,积极的主体(减轻他人的痛苦)与腹侧纹状体活动增加有关,而消极的主体(伤害他人)导致腹内侧前额叶皮质信号强烈下降,杏仁核激活。总的来说,我们的数据表明,明确的观点采择策略对与不同行为及其道德后果相关的神经募集有深远的影响。这项研究的结果可以为治疗社会情感障碍患者的干预措施和医学从业者的教育提供新的策略。
