道德决策是日常社会生活的核心，因为对另一个代理人的行为或我们自己的行为的评价与规范和价值观有关，指导我们在社区中的行为。先前有证据表明，身体伤害的存在，即使与决策无关，也可能影响决策过程。虽然最近的神经影像学研究发现了一个共同的神经基板的道德决策，身体伤害的作用还没有得到系统的研究。在这里，我们使用事件相关的功能磁共振成像（fMRI），以调查如何行为和神经相关的语义和道德的决策过程是调制的存在直接的身体伤害或暴力的刺激。12名参与者对描述代理人行为的句子做出了道德和语义决定，这些行为要么包含身体伤害，要么不包含身体伤害，并且可以很容易地被判断为好或坏或正确/不正确。在道德和语义决策，身体伤害的存在导致更快的反应时间（RT）和较弱的活动在时间极相对于审判没有身体伤害/暴力，表明处理优势和减少暴力相关的语言刺激的处理深度。值得注意的是，杏仁核和后扣带皮层（PCC）的活动没有增加，以响应包含身体伤害的试验。这些发现可能是一个相关的有限生成的语义和情感的背景下，在前颞极的另一个代理人的行为有关的暴力，这是相对于规范和价值观指导我们的行为在一个社区的评估。(C)2004爱思唯尔公司All rights reserved.
Moral decision-making is central to everyday social life because the evaluation of the actions of another agent or our own actions made with respect to the norms and values guides our behavior in a community. There is previous evidence that the presence of bodily harm-even if irrelevant for a decision-may affect the decision-making, process. While recent neuroimaging studies found a common neural substrate of moral decision-making, the role of bodily harm has not been systematically studied so far. Here we used event-related functional magnetic resonance imaging (fMRI) to investigate how behavioral and neural correlates of semantic and moral decision-making processes are modulated by the presence of direct bodily harm or violence in the stimuli. Twelve participants made moral and semantic decisions about sentences describing actions of agents that either contained bodily harm or not and that could easily be judged as being good or bad or correct/incorrect, respectively. During moral and semantic decision-making, the presence of bodily harm resulted in faster response times (RT) and weaker activity in the temporal poles relative to trials devoid of bodily harm/violence, indicating a processing advantage and reduced processing depth for violence-related linguistic stimuli. Notably, there was no increase in activity in the amygdala and the posterior cingulate cortex (PCC) in response to trials containing bodily harm. These findings might be a correlate of limited generation of the semantic and emotional context in the anterior temporal poles during the evaluation of actions of another agent related to violence that is made with respect to the norms and values guiding our behavior in a community.
