What core belief underpins Erikson's stages of development?

The core belief that underpins Erikson's stages of development is that they reflect a diverse emotional landscape. Erikson proposed eight stages through which a healthy developing individual passes from infancy to late adulthood. At each stage, individuals face specific psychosocial challenges that can lead to either positive or negative outcomes based on their experiences and interactions with others. This framework recognizes the importance of social relationships and emotional experiences in shaping personality and identity, highlighting how the nuances of each individual's life journey contribute to their development.

The stages encompass a range of emotions, conflicts, and social expectations, emphasizing that development is not a one-size-fits-all process but is influenced by diverse factors, including culture, relationships, and individual experiences. As such, the rich emotional landscape each individual navigates is central to Erikson's theory, making it a cornerstone of understanding human development.
