Erikson's stages of psychosocial development

Erikson's stages of psychosocial development, as articulated by Erik Erikson, in collaboration with Joan Erikson, is a comprehensive psychoanalytic theory that identifies a series of eight stages, in which a healthy developing individual should pass through from infancy to late adulthood. All stages are present at birth but only begin to unfold according to both a natural scheme and one's ecological and cultural upbringing. In each stage, the person confronts, and hopefully masters, new challenges. Each stage builds upon the successful completion of earlier stages. The challenges of stages not successfully completed may be expected to reappear as problems in the future.

However, mastery of a stage is not required to advance to the next stage. The outcome of one stage is not permanent and can be modified by later experiences. Erikson's stage theory characterizes an individual advancing through the eight life stages as a function of negotiating his or her biological forces and sociocultural forces. Each stage is characterized by a psychosocial crisis of these two conflicting forces (as shown in the table below). If an individual does indeed successfully reconcile these forces (favoring the first mentioned attribute in the crisis), he or she emerges from the stage with the corresponding virtue. For example, if an infant enters into the toddler stage (autonomy vs. shame and doubt) with more trust than mistrust, he or she carries the virtue of hope into the remaining life stages.

The first stage of Erik Erikson's theory centers around the infant's basic needs being met by the parents and this interaction leading to trust or mistrust. Trust as defined by Erikson is "an essential truthfulness of others as well as a fundamental sense of one's own trustworthiness." The infant depends on the parents, especially the mother, for sustenance and comfort. The child's relative understanding of world and society come from the parents and their interaction with the child. A child's first trust is always with the parent or caregiver; whomever that might be; however, even the caregiver is secondary where as the parents are primary in the eyes of the child. If the parents expose the child to warmth, regularity, and dependable affection, the infant's view of the world will be one of trust. Should the parents fail to provide a secure environment and to meet the child's basic needs; a sense of mistrust will result. Development of mistrust can lead to feelings of frustration, suspicion, withdrawal, and a lack of confidence.
