【摘要】：神经经济学关于人类决策行为的最新研究对实证主义传统讳莫如深的"大脑黑箱"进行了深刻剖析。本文通过对神经经济学"生理效用"理论和DDM模型及其应用价值的深入解读,发现大脑决策过程实则是神经系统对"满意程度"的生物计算和评估过程,即一个对决策价值信号赋值与比较的过程。这些研究第一次系统地在人们的内在神经活动与外在决策行为之间建立起了一种直观的联系,且认为如果决策行为是由大脑对决策价值进行适应性编码产生的,那么无论决策的情境有何差异,其在大脑决策机制中都有着相似的编码过程。因此存在一个对跨情境选择行为和反应时间做出一般预测的可能性,称为共同决策机制。这为解决简单情况下离散选择的样本外预测提供了新思路。显然,神经经济学正在深层次上悄然改变着经典经济学的固有思维模式,为决策理论的微观基础提供了全新的科学诠释。
[Abstract]:The latest research on human decision-making behavior in neuroeconomics makes a profound analysis of the "brain black box" of positivism tradition. In this paper, by analyzing the "physiological utility" theory of neuroeconomics, DDM model and its application value, it is found that the brain decision-making process is the biological calculation and evaluation process of the satisfaction degree of the nervous system. It is a process of assigning and comparing decision-making value signals. For the first time, these studies have systematically established an intuitive link between people's internal neural activity and external decision-making behavior, and believe that if decision-making behavior is generated by the brain's adaptive coding of decision value, Therefore, regardless of the circumstances of decision-making, there is a similar coding process in the brain decision-making mechanism. Therefore, there is a possibility to make a general prediction of cross-situational selection behavior and reaction time, which is called common decision mechanism. This provides a new way to solve the simple case of discrete selection of extrasample prediction. Obviously, neuroeconomics is quietly changing the inherent mode of thinking of classical economics, which provides a new scientific interpretation for the micro basis of decision-making theory.
