Now, let’s turn to a less controversial psychodynamic theorist, the father of developmental psychology, Erik Erikson.

The Ego Rules

Erik Erikson (1902-1994) was a student of Freud’s and expanded on his theory of psychosexual development by emphasizing the importance of culture in parenting practices and motivations and adding three stages of adult development (Erikson, 1950; 1968). He believed that we are aware of what motivates us throughout life and the ego has greater importance in guiding our actions than does the Id. We make conscious choices in life and these choices focus on meeting certain social and cultural needs rather than purely biological ones. Humans are motivated, for instance, by the need to feel that the world is a trustworthy place, that we are capable individuals, that we can make a contribution to society, and that we have lived a meaningful life. These are all psychosocial problems. Erikson divided the life span into eight stages. In each stage, we have a major psychosocial task to accomplish or crisis to overcome.  Erikson believed that our personality continues to take shape throughout our life span as we face these challenges in living.  We will discuss each of these stages in length as we explore each period of the life span, but here is a brief overview:

Psychosocial Stages

1. Trust vs. mistrust (0-1): the infant must have basic needs met in a consistent way in order to feel that the world is a trustworthy place
2. Autonomy vs. shame and doubt (1-2): mobile toddlers have newfound freedom they like to exercise and by being allowed to do so, they learn some basic independence
3. Initiative vs. Guilt (3-5): preschoolers like to initiate activities and emphasize doing things “all by myself”
4. Industry vs. inferiority (6-11): school aged children focus on accomplishments and begin making comparisons between themselves and their classmates
5. Identity vs. role confusion (adolescence): teenagers are trying to gain a sense of identity as they experiment with various roles, beliefs, and ideas
6. Intimacy vs. Isolation (young adulthood): in our 20s and 30s we are making some of our first long-term commitments in intimate relationships
7. Generativity vs. stagnation (middle adulthood): the 40s through the early 60s we focus on being productive at work and home and are motivated by wanting to feel that we’ve made a contribution to society
8. Integrity vs. Despair (late adulthood): we look back on our lives and hope to like what we see-that we have lived well and have a sense of integrity because we lived according to our beliefs.

These eight stages form a foundation for discussions on emotional and social development during the life span. Keep in mind, however, that these stages or crises can occur more than once. For instance, a person may struggle with a lack of trust beyond infancy under certain circumstances. Erikson’s theory has been criticized for focusing so heavily on stages and assuming that the completion of one stage is prerequisite for the next crisis of development. His theory also focuses on the social expectations that are found in certain cultures, but not in all. For instance, the idea that adolescence is a time of searching for identity might translate well in the middle-class culture of the United States, but not as well in cultures where the transition into adulthood coincides with puberty through rites of passage and where adult roles offer fewer choices.
