Positive emotions refer to emotions accompanied by pleasant feelings, such as happiness, interest, satisfaction, pride, and love, which are generated by individuals in response to internal and external stimuli and events. Positive emotions are conscious processes that involve a variety of components, such as a pleasant experience, facial/body expressions, evaluations, and especially behavioural plans and activation states. People's cognitive process is often accompanied by emotions, and the influence of positive emotions on cognitive activities has gradually become the focus of research in recent years. This study constructs a regulation model and an assessment model of positive emotions, and analyses the neural mechanisms of the effects of dopamine substances on human positive emotions.
