• Unit 5: Development

    The physical, mental, and emotional changes that an individual undergoes over the course of his or her lifetime raise a number of questions about who we are and how we develop as human beings. One such question is whether our traits are stable or changeable throughout our lifetime; another is whether development is a continuous, gradual process or a set of discrete stages. Though these questions remain unresolved, this unit will provide you with ways to think critically about these issues. It will also provide you with an overview of human development, from infancy to old age.

    Completing this unit should take you approximately 7 hours.
