Psychosocial Development Theory In the history of psychoanalysis, Sigmund Freud was the first to delve into the unknown recesses of the human mind to identify reasons for neuroses. As such, he identified infantile sexuality to lie at the heart of most problems in the relationship with the self and others and used the three-dimensional model of the id, the ego, and superego to describe the various ways in which these neuroses manifested themselves.

Even though many today reject some or most of the early philosopher's ideas, it is thanks to him that these theories have a reason for existence in themselves. Today, the theory known as psychosocial development bases many of its concepts on the early ideas conceptualized by Freud. As such, theorists like Erik Erikson, Alfred Adler, and Karen Horney have developed their own concepts of what it means to develop as a human being from childhood to adulthood today.

The second stage is the development of autonomy vs. shame and doubt, which focuses on the increasingly complex familial and social relationships a child develops with others and with the self. Stage 3 is initiative vs. guilt, where autonomy develops further into initiative. Depending on the levels of initiative and guilt, stage 4 focuses on industry vs. inferiority. This is where the individual either distinguishes him- or herself as a fully conscious, free-thinking person or a conformist who can be manipulated by others. The development of identity vs. role confusion is the next stage, while intimacy vs. isolation is the sixth stage. The generativity in stage 7 develops from healthy intimate and professional relationships, while stagnation is its opposite. Erikson emphasizes that a desire to establish and guide the next generation, as well as…
