The volume examines childhood as a dynamically transforming developmental stage shaped by the expanding influence of digital technologies, particularly artificial intelligence, and situates play as a central medium for learning, social participation, and emotional regulation. Across its interdisciplinary chapters, the book explores how AI-supported psychoeducation restructures psychological support systems by introducing personalized, data-driven, and accessible intervention models while simultaneously raising ethical concerns related to privacy, algorithmic bias, and cultural appropriateness. Complementary sections analyze the function of play in promoting participation and developmental gains among children with special needs, highlighting how structured playful interactions foster cognitive flexibility, social communication, and inclusive educational experiences. The work further investigates young children’s perceptions of doctors, hospitals, and nurses, demonstrating how early health understandings emerge through social cues, experiential narratives, and cultural contexts, and emphasizing the need for developmentally sensitive communication in health education. Additionally, the book presents the process of developing a yoga-based emotion-regulation program, integrating mindfulness, somatic awareness, and developmental psychology to support children’s self-regulation capacities. By synthesizing technological, psychological, pedagogical, and sociocultural perspectives, the book contributes to contemporary scholarship on childhood studies, early education, and mental-health-support systems, offering a conceptual and practical framework for understanding how emerging technologies and evidence-based interventions are reshaping developmental environments.
