Answer :
A leading and important theory of development was created by ego psychologist Erik Erikson. Erikson's theory focused more on psychosocial than psychosexual development, despite the influence of psychoanalyst Sigmund Freud's work.
Erikson's theory, however, addressed the effects of social experience throughout the entire lifespan, in contrast to Freud's conception of psychosexual phases.
