Developmental Psychology (Student Handbook to Psychology, 5) by Lynn M. Shelley

People undergo vast changes in a lifespan. Developmental Psychology shows how we change as we gradually move from infancy into childhood and, ultimately, through adulthood and old age. The processes of development are affected both by the environment and by our genetic makeup in complex and interesting ways. The development of our ultimate ways of thinking, socializing, and feeling result from the world we encounter as we move through life.
