Abstract: Childhood experiences research has been a significant topic in the fields of education and psychology. While research on adverse childhood experiences (ACEs) is relatively mature, studies on positive childhood experiences (PCEs) in China remain scarce. In recent years, international research on PCEs has increased, covering their definition, project construction, theoretical foundations, and their multifaceted impacts on individual development. This paper systematically reviews the progress of PCEs research abroad, explores their positive effects on psychological, physical, and social health, and analyzes the implications for related research and practices in China. By drawing on international research outcomes, this paper aims to provide theoretical and practical references for building a more scientific and comprehensive support system for child development in China.

Key words: positive childhood experience (PCE), psychological health, individual development
