Explanation:

One of the important aspect of Psychology is the studying of how human beings develop from cradle to adult that is their Behavior and so many other things. Erikson was one of the the Psychologists that worked on the development of human beings. According to Erikson there are 8 stages in the development of human beings and they are;

(1). Infancy (Trust vs. Mistrust), (2). Autonomy vs. Shame, (3). Preschool Years (Initiative vs. Guilt), (4). Early School Years (Industry vs. Inferiority), (5). Adolescence (identity vs. Role Confusion), (6). Young Adulthood (Intimacy vs. Isolation), (7). Middle Adulthood (Generativity vs. Stagnation) and (8). Late Adulthood (Ego Integrity vs. Despair).

Another Psychologist; Robert Peck later came up to study more on the 8th stage that is Late Adulthood (Ego Integrity vs. Despair) that was proposed by Erikson. According to him, social differentiation is to affirm self with with something that does not relate with work for instance, friends and family as emotional development occur in late adulthood.
