David Elkind

David Elkind is an American child psychologist and author. His groundbreaking books The Hurried Child and Miseducation informed early childhood education professionals of the possible dangers of "pushing down" the elementary curriculum into the very early years of a child's life. By doing so, he argued, teachers and parents alike could lapse into developmentally inappropriate instructional and learning practices that may distort the smooth development of learning. He is associated with the belief of decline of social markers.

He also wrote Ties that Stress: The New Family Imbalance (1994), All Grown Up and No Place To Go (1988), and Reinventing Childhood (1988). His most recent article titled, "Can We Play?", is featured in Greater Good magazine (published by the Greater Good Science Center), and discusses how play is essential to positive human development but children are playing less than in previous eras.
