Erik Erikson as a developmental psychologist who proposed the theory of psychosocial development. which outlines eight stages of human development across the lifespan. Each stage is characterized by a unique psychosocial crisis or conflict that individuals must resolve in order to progress to the next stage. The first stage is trust vs mistrust (0-1), during infancy, the primary psychosocial task is to develop a sense of trust in the world and caregivers. Infants rely on their caregivers for basic needs and emotional support. The next stage is autonomy vs shame (1-3), toddlers begin to assert their independence and explore their environment. The key challenge is to develop a sense of autonomy while still maintaining a sense of security. Then the intiatve vs guilt stage (3-6), During the preschool years, children become more assertive and take initiative in exploring their environment and interacting with others. Industry vs. Inferiority (6-12 years), children develop a sense of competence and mastery in various social, academic, and recreational activities. Identity vs. Role Confusion (12-18 years), adolescence is marked by the search for identity and a sense of self. Individuals explore different roles, values, and beliefs as they strive to establish a coherent identity. Intimacy vs. Isolation (18-40 years), young adults seek meaningful relationships and intimacy with others. Generativity vs. Stagnation (40-65 years), middle-aged adults focus on contributing to the well-being of future generations and making meaningful contributions to society. The psychosocial task is to find satisfaction in work, relationships, and caregiving roles. Integrity vs. Despair (65+), in late adulthood, individuals reflect on their lives and accomplishments. The primary challenge is to achieve a sense of integrity by accepting the successes and failures of the past and finding meaning and fulfillment in life.

Moral development refers to the process through which individuals acquire an understanding of right and wrong, develop ethical principles, and learn to apply these principles in their interactions with others. This development typically occurs over the lifespan and is influenced by various factors including cognitive, social, cultural, and emotional aspects. Early Childhood, during early childhood moral development begins with the formation of simple understandings those being, fairness, empathy, and sharing. In early childhood the child wil often exibit behaviors guided by simple rules that a caregiver has put into place. Middle childhood, during middle childhood moral reasoning becomes more complex, children begin to grasp more concepts and are able to start detecting right from wrong. They begin to understand following rules and avoiding punishments. Adolescence, in adolescence moral development progresses becasue induviduals are able to engage in more abstract thinking and consider moral dilemas in multiple viewpoints. Adulthood, contuining into adulthood moral development continues to progress but is more effected by ongoing events.
