In conclusion of this article I would like to mention that,
Erickson theory is fully based on five principles. He believes that all human
have the some basic needs and individual development depends on reaction
towards these basic needs. Everyone wants to achieve his/her basic needs in
their life. Therefore Erickson concluded that human development progresses
according to specific stages. He also states that each of those stages has
crisis and those crisis must be dissolved before an individual can function
successfully at the next stage.
Indeed, Erikson (1964) “acknowledges his theory is more a
descriptive overview of human social and emotional development that does not
adequately explain how or why this development occurs.” For example, Erikson
does not explicitly explain how the outcome of one psychosocial stages
influence personality at a later stage. However, one of the strengths of
Erikson's theory is its ability to tie together important psychosocial
development across the entire lifespan. Although support for Erikson's stages
of personality development exists (McAdams, 1999), critics of his theory
provide evidence suggesting a lack of discrete stages of personality
development (Costa and McCrae, 1997).
