Final answer:
Erikson's stages of development involve completing various psychosocial tasks in order to achieve a sense of competence and a healthy personality.
Step-by-step explanation:
Erik Erikson proposed a theory of psychosocial development that consists of eight stages. In each stage, there is a psychosocial task that individuals must master in order to achieve a sense of competence. These tasks include developing trust, achieving autonomy, forming identity, establishing intimacy, and generativity, among others. Successful completion of these tasks leads to a healthy personality, while failure may result in feelings of inadequacy.
