Research in decision theory typically employs the assumption of the rational actor as a premise,with rationalism as its theoretical foundation.This emphasis on rational decision-making,while neglecting the role of emotions,fails to adequately explain and guide actual decision-making processes.Among the three research paradigms in behavioral decision-making,the normative decision-making paradigm negates the in-fluence of emotions on decisions,asserting that measurable preferences can help individuals make choices that maximize utility;the descriptive decision-making paradigm begins to focus on the role of emotions in decision-making,with theories such as regret theory,disappointment theory,and subjective expected util-ity theory elaborating on the role of cognition,thinking,and psychological processes in the decision-mak-ing process;the evolutionary decision-making paradigm,starting from ecological rationality,argues that emotions,experiences,and implicit cognition play a crucial role in human decision-making behavior.There are two mainstream views on the operating mechanism of emotions in the decision-making process:one views emotions as a driving mechanism of the decision-making process,while the other sees emotions as an adaptive mechanism in the evolutionary process that influences the decision-making process.Both of these mechanisms are important for the decision-making process,but they are not sufficient to fully explain the complexity and interactivity of emotions in decision-making.Emotions,as a functional state,help to in-tegrate cognitive,rational thinking,and emotional abilities through generative mechanisms in decision-making processes,within the collective influence of the brain,body,and environment.
