His ideas, though, were greatly influenced by Freud, going along with Freud’s ideas about the structure and topography of personality.
However, whereas Freud was an id psychologist, Erikson was an ego psychologist. He emphasized the role of culture and society and the conflicts that can take place within the ego itself, whereas Freud emphasized the conflict between the id and the superego.
According to Erikson, the ego develops as it successfully resolves crises that are distinctly social in nature. These involve establishing a sense of trust in others, developing a sense of identity in society, and helping the next generation prepare for the future.
Erikson extends on Freudian thoughts by focusing on the adaptive and creative characteristic of the ego, and expanding the notion of the stages of personality development to include the entire lifespan.
Erikson proposed a lifespan model of development, taking in five stages up to the age of 18 years and three further stages beyond, well into adulthood. Erikson suggests that there is still plenty of room for continued growth and development throughout one’s life.
Erikson put a great deal of emphasis on the adolescent period, feeling it was a crucial stage for developing a person’s identity.
Like Freud and many others, Erik Erikson maintained that personality develops in a predetermined order, and build upon each previous stage. This is called this the epigenic principle.
The outcome of this 'maturation timetable' is a wide and integrated set of life skills and abilities that function together within the autonomous individual. However, Instead of focusing on sexual development (like Freud), he was interested in how children socialize and how this affects their sense of self.
