Erikson's stages of psychosocial development, as articulated in the second half of the 20th century by Erik Erikson in collaboration with Joan Erikson, is a comprehensive psychoanalytic theory that identifies a series of eight stages that a healthy developing individual should pass through from infancy to late adulthood.

According to Erikson's theory the results from each stage, whether positive or negative, influences the results of succeeding stages. Erikson published a book called Childhood and Society in 1950 that made his research well known on the eight stages of psychosocial development. Erikson was originally influenced by Sigmund Freud's psychosexual stages of development. He began by working with Freud's theories specifically, but as he began to dive deeper into biopsychosocial development and how other environmental factors affect human development, he soon progressed past Freud's theories and developed his own ideas. Erikson developed different substantial ways to create a theory about lifespan he theorized about the nature of personality development as it unfolds from birth through old age or death. He argued that the social experience was valuable throughout our life to each stage that can be recognizable by a conflict specifically as we encounter between the psychological needs and the surroundings of the social environment.

Erikson's stages of psychosocial development

Erikson's stage theory characterizes an individual advancing through the eight life stages as a function of negotiating their biological and sociocultural forces. The two conflicting forces each have a psychosocial crisis which characterizes the eight stages. If an individual does indeed successfully reconcile these forces (favoring the first mentioned attribute in the crisis), they emerge 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, they carry the virtue of hope into the remaining life stages. The stage challenges that are not successfully overcome may be expected to return as problems in the future. However, mastery of a stage is not required to advance to the next stage. In one study, subjects showed significant development as a result of organized activities.

Existential Question: Can I Trust the World?

The first stage of Erik Erikson's theory centers around the infant's basic needs being met by the parents or caregiver and how this interaction leads to trust or mistrust. Trust as defined by Erikson is "an essential trustfulness 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. Infants will often use methods such as pointing to indicate their interests or desires to their parents or caregivers. The child's relative understanding of the world and society comes from the parents and their interaction with the child. Children first learn to trust their parents or a caregiver. If the parents expose their child to warmth, security, and dependable affection, the infant's view of the world will be one of trust. As the child learns to trust the world around them, they also acquire the virtue of hope. Should 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 later lead to feelings of frustration, suspicion, withdrawal, and a lack of confidence.

According to Erik Erikson, the major developmental task in infancy is to learn whether or not other people, especially primary caregivers, regularly satisfy basic needs. If caregivers are consistent sources of food, comfort, and affection, an infant learns trust — that others are dependable and reliable. If they are neglectful, or perhaps even abusive, the infant instead learns mistrust — that the world is an undependable, unpredictable, and possibly a dangerous place. Having some experience with mistrust allows the infant to gain an understanding of what constitutes dangerous situations later in life. However, infants and toddlers should not be subjected to prolonged situations of mistrust. This causes children to be ill adjusted later in life and see life with a cautious and careful outlook, which can be detrimental later in their life. In this stage, the child's most important needs are to feel safe, comforted, and well cared for.
