摘要:
攻击行为在人类社会中非常普遍，社会心理学家把攻击行为定义为，个体蓄意给他人身体或心理带来某种伤害，并且知觉到这种伤害的行为(Anderson & Bushman, 2002)。利用ERP和fMRI技术研究攻击行为的神经机制发现：1) 攻击行为的过程反应主要体现在早期诱发50 ms左右出现的听觉P50波，中期对错误刺激监测的错误相关负波(ERN)，以及晚期P300波等ERP成分；2) 攻击行为的神经基础涉及前额叶(PFC)、前扣带回(ACC)、杏仁核(Amygdala)和下丘脑(Hypothalamus)等大脑空间结构。整合这些研究可以发现，攻击行为的脑电反应过程可能是自下而上，而神经基础可能是是自上而下的加工过程。未来要进一步比较动物攻击行为和人类攻击行为的神经机制模型差异，整合ERP和fMRI研究以及设计实验探测工具性攻击行为的神经机制。Human aggression is defined to any behavior directed toward another individual that is carried out with the proximate intent to cause harm (Anderson & Bushman, 2002). 1) Researches on recent decades show that the majority of event-related potentials (ERPs) associated with aggression contained P50 induced by auditory gating, Error Related Negativity (ERN) produced by the progress of error information and later period of P300; 2) By functional magnetic resonance imaging (fMRI) studies, the neural mechanism of aggression contained prefrontal cortex (PFC), anterior cingulate cortex (ACC), amygdala, hypothalamus and so on. The progresses of ERP response and neural mechanism of aggression were bottom-up and top to bottom. In the future direction, we should make a comparison on animal and human aggression neural mechanism, and we should make ERP and fMRI integrate to research human aggression. Then the neural mechanism of instrumental-controlled aggression should be explored by these methods.
