Abstract This mixed-methods study investigates the impact of play and educational toys on cognitive (e.g., problem-solving) and emotional (e.g., empathy) development in elementary students aged 6–12. A PRISMA-guided systematic review of 87 articles from Scopus, Web of Science, PubMed, SID, and Magiran (2010–August 2025), combined with a VOSviewer co-authorship network analysis of 78 researchers, reveals key insights. Structured play (e.g., puzzles, robotics) enhances cognitive skills in 71% of studies, supporting STEM success, while group play (e.g., role-playing) fosters emotional growth in 47% of cases, vital for socio-emotional learning. Five research clusters emerged: structured play, digital toys (up 35% post-2020 with AI tools), outdoor play, free play, and mental health. Influential authors like Pyle bridge these domains. Unlike prior cognition-focused reviews (e.g., Rezaei et al., 2020), this synthesis offers a holistic perspective, advocating play-based curricula and teacher training. Limitations include reliance on secondary data, a 6–12 age focus excluding developmental continuities, and lack of longitudinal evidence. Future research should explore long-term emotional effects, cultural variations, and use random-effects models for heterogeneous studies, emphasizing Iran’s context and COVID-19’s influence (Wang et al., 2025).
