What do the eight stages in theory of psychosocial development have common?

The stages in the theory of psychosocial development have several commonalities:

1. Erikson's stages are sequential, meaning that each stage builds on the previous one.

2. Each stage involves a conflict or crisis that must be resolved in order to move on to the next stage.

3. The conflicts in each stage are related to different aspects of development, such as trust versus mistrust, autonomy versus shame and doubt, and generativity versus stagnation.

4. The way that an individual resolves each conflict affects their development and sense of self.

5. The resolution of each conflict leads to the development of certain strengths or virtues.

6. The stages are universal, meaning that they apply to all people regardless of their culture or background.

7. The stages are not fixed, meaning that individuals can regress or progress to different stages at different points in their lives.

8. The theory of psychosocial development emphasizes the importance of both nature and nurture in development, as well as the interaction between the two.
