"Child Psychology III: The Kindergarten Child: Thought, Imagination and Feeling; Will and Morale" by Vilhelm Rasmussen was and continues to be a useful reference text that looks at the developing minds of young children. The book was written for parents, guardians, and teachers so that they can better understand the way a child processes things at the young and very impressionable kindergarten age when they are first learning about individual thought, complex imagination, and the idea of morality.
