Trust vs. Mistrust: This is the first stage in Erikson's theory, which occurs during infancy. It refers to the challenge of developing trust in others and feeling secure in one's environment.
Intimacy vs. Isolation: This is one of the stages that corresponds to adulthood (specifically young adulthood). It focuses on forming deep emotional connections and intimate relationships with others while avoiding feelings of isolation or loneliness.
Generativity vs. Stagnation: This is another stage that corresponds to adulthood (specifically middle adulthood). It involves finding meaning and purpose in life by contributing to society through work, family, or other meaningful activities rather than feeling stagnant or unproductive.
