Play Theory is a concept in psychology and education that explores the importance of play in human development. It suggests that play is a vital activity for children, helping them learn social skills, problem-solving, and creativity. Through play, children can experiment with different roles and scenarios, which aids in their cognitive and emotional growth. The theory is often associated with figures like Jean Piaget and Lev Vygotsky, who emphasized the role of play in learning. They believed that play allows children to make sense of the world around them and develop essential life skills in a safe and enjoyable environment.
