Who is a key figure in psychosocial development theory?

Erik Erikson is a pivotal figure in psychosocial development theory, known for his stage theory that outlines eight distinct stages of human development across the lifespan. Each stage is characterized by a central conflict that individuals need to resolve to develop a healthy personality and acquire basic virtues. For instance, his first stage, trust vs. mistrust, occurs in infancy and is crucial for developing a sense of security. Erikson's emphasis on the social and emotional aspects of development, particularly how relationships and societal influences shape individual identity, differentiates his theory from others that focus primarily on cognitive or psychosexual development.

While Carl Jung, Jean Piaget, and Sigmund Freud have made significant contributions to psychology, their focuses differ from Erikson's. Jung explored concepts like archetypes and the collective unconscious, Piaget is known for his stages of cognitive development, and Freud emphasized psychosexual stages and unconscious drives. Therefore, Erikson’s work remains foundational in understanding psychosocial development, firmly establishing him as the key figure in this area.
