This paper explores the impact of family upbringing environment on children's emotions and behaviors, and analyzes its theoretical framework and research findings. Firstly, we delve into the concept of family upbringing environment, including factors such as family atmosphere, parenting styles, and family support systems. Subsequently, we systematically review relevant literature, discussing the mechanisms through which different family upbringing environments influence children's emotions and behaviors. We find that warm and supportive family environments typically promote healthy emotional development in children and contribute to the formation of positive behavioral patterns; conversely, hostile and indifferent family environments may lead to emotional problems and behavioral abnormalities in children. Further analysis indicates that the influence of family upbringing environment on children extends beyond emotions and behaviors, profoundly impacting their psychosocial development. Finally, this paper proposes suggestions for future research, aiming to deepen understanding of the comprehensive impact of family upbringing environment on children and provide more effective intervention strategies for promoting children's healthy development.
