In the history of psychology, there have been many different areas of interest. Human development, in particular, has been one of the interesting areas of study for many psychologists. Freud, Erikson, and Piaget are all great theorists with similar, but different, ideas about human development. Their theories of human development had humans passing through different stages of aging. Although all three theorists have common relationships in that they developed their ideas and theoretical stages for human development throughout the lifespan, each theory represents its own uniqueness as to what these stages were, on what they focus on and where they also relate to human development.
