远离“诱惑”:预先承诺对跨期决策的调控机制及其神经基础

Stay away from "temptation" : The regulatory mechanisms and relevant neural basis for the association between pre-commitment and intertemporal choice

预先承诺作为一种有效的自我控制策略,主要通过提前排除那些在未来决策中可能会诱使个体做出冲动决策的选项,以达到降低决策冲动性的目的。预先承诺调控跨期决策主要是通过侧额极皮层(LFPC)、背外侧前额叶(DLPFC)、腹内侧前额叶(vmPFC)、后顶叶皮层(PPC)等脑区的共同激活,在自我控制、价值估算、特质冲动性、惩罚敏感度等心理变量的影响下发挥作用。本研究分别从认知机制和神经基础两个方面提出预先承诺降低冲动决策的整合模型,为干预和降低个体决策冲动性提供理论借鉴。未来研究可进一步探究预先承诺调控跨期决策的心理与神经机制,并加强预先承诺在决策领域的应用研究。

Pre-commitment,as an effective self-control strategy,can reduce the impulsivity of decisionmaking primarily through precluding the options in advance that may prompt individuals to make impulsive decisions.Pre-commitment regulates the intertemporal choice primarily via activating the lateral frontopolar cortex(LFPC),dorsolateral prefrontal cortex(DLPFC),ventromedial prefrontal cortex(vmPFC)and posterior parietal cortex(PPC),which is also affected by self-control,value estimation,trait impulsivity,punishment sensitivity and other relevant psychological processes.This study proposes an integrated model,which contains cognitive mechanism and neural basis for the role of pre-commitment in reducing impulsive decision-making.The model provides theoretical foundation and important implications for reducing impulsive decision-making.Future research should continue to examine the psychological and neural mechanisms for the regulatory role of pre-commitment in intertemporal choice.Additionally,it is significant to investigate how pre-commitment impacts decision making in applied research.
