In this activity you will learn about some of the biological, cognitive, and psychosocial developments that take place from birth across the life span. As you explore, keep in mind the following questions that are on the forefront of the developmental psychology: How do innate and environmental factors interact? What relationships exist between development in one period of life and development in another? How might differences in culture and social class shape the course of development?

Follow each tab in sequence to explore life span development.
