Thesis advisor: Julia Fisher / The future of imaginative playtime in the lives of children today is at great risk. Currently, 40% of schools are considering eliminating- or have already eliminated- recess from the school day. The goal of this essay is to argue the irreplaceable value that imaginative play has in contributing to the cognitive, emotional, and social growth of a child. In making a case for the importance of play in child development, all three of these areas of potential growth will collectively be considered as true development of the child. To lay the foundation for these specific categories of benefits, it is necessary to understand the general biological background supporting the innate importance of play, as well as the previous work of those who have researched this subject. Once this information is presented, the cognitive, emotional, and social benefits of imaginative play will be explored in more detail, and the effects of play deprivation and play reintroduction will be discussed. In this manner, it is the aim of this presentation to demonstrate the exceptional importance of imaginative play. / Thesis (BA) — Boston College, 2007. / Submitted to: Boston College.
