Compare and contrast the psychosocial stages of middle (Generativity vs. Stagnation) and later adulthood (Ego Integrity vs. Despair) as discussed by Erikson. What skills (tasks) are important in both periods for successful development, and what skills are relatively unique to each stage for successful development? What characteristics of behavior in the former must change in order to develop successfully in the latter? Also, what other developmental theory did these two stages remind you of from other theorists and why? Please use examples to support your statements.
