Narcissism has been considered a prevalent personality trait. In the process of exploring the structure and model of narcissism,prior research has neglected the formation and development of children narcissism.Currently,most studies on formation of childhood narcissism focuses on two aspects: physiological factors and social experience. Physiological factors mainly include causes of temperamental traits,endocrine system and neural system,while social experience principally relates to parental overvaluation and the dynamic self-regulatory processing model. Taking self-evaluation within different cognition development levels into account,the present study presents the development of narcissism from early childhood to adolescence. Further researches are expected to uncover the mechanisms of narcissism and research methods and interventions on it.
