With the continuous development of decision-making psychological research field, decision researchers are paying increasing attention on the role of emotion plays in decision-making process. Based on the development of emotion theory, Cognitive Appraisal theory of emotions, Moral Emotions Theory and Motivational Dimensional Model of Affect bring new views on emotion for decision researchers. Because of the emergence of newly developing emotion perspective, the decision researchers deepened the knowledge of the mechanisms for decision-making. The Affect Infusion Model, Risk Analysis Dual Theory, Emotion as Social Information Model and Neural Affective Decision Theory are developed to describe how emotion plays a role in different types of decision-making. Based on the review of above models, the authors makes some recommendations on future research direction. The first, to strengthen validation researches of related emotion theories in different types of decision-making situations. The second, to make further thinking about mechanism of emotion in different types of decision making at perspectives of embodied emotion. The third, to take more broadly aspects into account the characteristics of emotion and cognition, integrate theoretical system at the perspective of interaction between emotion and cognition. Finally, to pay more attention to the interpretations of the natures of different emotions and their mechanism in decision-making. In addition, both emotional and cognitive regulations have certain universality and complexity, and have huge potential adaptive roles. How to make a better understanding and interpretation of such emotion-cognition regulation relationship in psychological experiments has brought challenges and expectation for future researchers.
