The Learning Child

Hailed as a classic in developmental psychology, The Learning Child is as relevant today as when it was first published in 1972, if not more so. Drawing on the findings of psychologists like Piaget, and on the author's own experiences teaching child development at New York’s Bank Street College, Cohen explores the crucial links between learning and the successive stages of childhood, and shows parents and teachers how to turn a child’s natural instinct for inquiry into a talent for learning that will last a lifetime.
 
“If American parents will read and listen to Dr. Cohen’s sensible, wise analysis of the way young children learn, my faith in human beings will be restored! . . . It was refreshing and reassuring to read a book by someone who approaches childhood with love and profound wisdom.” —Eda LeShan, author of When Your Child Drives You Crazy
