Title:  Identity Development Throughout the Lifetime: An Examination of Eriksonian Theory Author: Justin T. Sokol Date Published: March 1, 2009 Why Relevant and Summary: Erikson's theories are relevant to almost all types of research on identity development. Identity development is a life-span process, as Eriksonian theories suggest. This particular publication is an in depth examination of Erikson's theories on identity development: identification in early childhood, Identity formation in adolescence, identity development in adulthood. How This Influenced My Thinking: I agree with the research: Identity development is an ongoing process that continues through adulthood. I see examples of this looking over my childhood, adolescence and adulthood so far. At 32 years old, I can honestly agree with Erikson's theories on identity development - I feel as though my identity (though does not change drastically anymore) certainly continues to develop.
