Which one of the theories discussed in Chapters 3 and 4 of our course textbook do you think is most useful in understanding and explaining personality development in contemporary society? Explain your position. Be sure to select a theory, briefly describe it and name the theorist, rather than a general concept. Link your chosen theory directly to aspects of personality development in contemporary society you are attempting to explain rather than only summarizing the theory. The theory I chose is Erik Erikson’s Life Span Identity theory .
