Games, both video and board games, have long been recognized as influential in human development, fostering cognitive, emotional, and social growth. During adolescence and young adulthood, critical periods of neurobiological and social transition games serve as platforms for peer interaction, identity exploration, and social competence development. This chapter examines the role of games in social and cognitive development, drawing insights from developmental psychology, neuroscience, and communication studies. While strategic and cooperative gaming can enhance executive functions, problem-solving, and teamwork, excessive gaming may pose risks such as social withdrawal and impaired face-to-face interactions. Research indicates that moderate gaming can strengthen peer relationships, improve empathy, and serve as a medium for stress relief and emotional resilience. However, unregulated gaming habits, particularly in toxic online environments, may contribute to negative behavioral patterns. The chapter explores both the benefits and challenges of gaming, emphasizing the need for balanced engagement to maximize its positive contributions while mitigating potential risks. Future research should investigate long-term effects and develop strategies to optimize gaming experiences for cognitive and social well-being.
