死亡凸显对静息态β2的影响
The Effect of Mortality Salience on the Resting State of β2
摘要: 根据恐惧管理理论，死亡的不可避免性会诱发恐惧和焦虑。为了缓解焦虑，人们在意识层面和潜意识层面都会建立防御机制。已有研究发现死亡凸显会影响个体的行为，但对死亡凸显本身对大脑神经活动的影响还尚未可知。本研究采用事件相关电位技术，探索死亡启动后对意识层面和潜意识层面静息态脑活动的影响，研究发现近端防御(意识层面)中β2节律上默认网络的活动降低，远端防御(潜意识层面) β2能量增高，且β2节律上默认网络的活动降低。表明近端防御会抑制自我信息的加工，远端防御中不但会抑制自我信息的加工也会增加警觉程度。
Abstract: According to the theory of fear management theory, the inevitability of death induces fear and anxiety. In order to alleviate anxiety, people will establish defense mechanisms at both the level of consciousness and the level of subconsciousness. It has been found that the death information will affect people’s behavior, and the impact on the rest state is still unknown. In this study, event-related potential techniques were used to explore the effects of death initiation on resting and subconscious levels of resting brain activity. The study found that the default network activity of β2 rhythm was reduced in the proximal defense (conscious level), and the distal defense (subconscious level). The β2 energy is increased, and the activity of the default network on the β2 rhythm is lowered. It shows that the near-end defense will inhibit the processing of self-information, and the remote defense will not only inhibit the processing of self-information but also increase the alertness.
