This textbook is an introduction to human development as it relates to psychology.

This is an updated version. Introduction to Lifespan Development (Fall 2019)
Lifespan Development examines the physical, cognitive, and socioemotional changes that occur throughout a lifetime. This course covers the essentials in understanding human development, psychological research, and theories of growth and development. Students will come to understand the lifespan perspective and to analyze growth through each of the major stages of development: prenatal development, infancy, early childhood, middle childhood, adolescence, early adulthood (including emerging adulthood), middle adulthood, and late adulthood. The course covers key topics in each of these stages, including major developmental theories, genetics, attachment, education, learning, disabilities, parenting, family life, moral development, illnesses, aging, generativity, and attitudes towards death and dying.

Faculty members may readily adapt the course’s OER content to include new developments and research to equip students with what they need to have success in their sociological journey.
