Final answer:
Erikson's psychosocial theory highlights that both biological traits and internal psychological factors, along with psychosocial influences, contribute to the development of a healthy personality through various stages of life.
Step-by-step explanation:
Erikson believed that psychosocial forces in combination with biological traits and internal psychological factors were major contributions to the development of a healthy person. Notably, Erikson's psychosocial theory of development is a notable theoretical framework that diverges from Freud's psychosexual stages, emphasizing the lifelong process of personality development through the interaction of eight distinct stages. From birth to late adulthood, each stage poses a psychosocial task, with a successful resolution leading to a sense of competence and thus contributing to the formation of a healthy personality.
Erikson's approach points to the intricate weaving of genetic, biological, and social factors into the fabric of our personalities. His work emphasizes the social nature of development, suggesting a model in which personality is not static but is continually shaped by social interactions, challenges, and the need for personal competence throughout one's life.
