Erikson’s Psychosocial Development Theory: Key Concepts and Stages

Erik Erikson

A developmental psychologist who expanded Freud's ideas and emphasized social and cultural influences across the entire lifespan.

Importance in Psychology

Introduced the psychosocial theory of development, highlighting lifelong stages, identity formation, and social relationships.

Epigenetic Principle

Development unfolds in a predetermined sequence; each stage builds on the previous one. Not a 'rosary of achievement,' meaning stages are not simply tasks to check off.

Psychosocial Crisis

Each stage presents a conflict between two opposing outcomes; successful resolution leads to healthy development.

Basic Trust vs. Mistrust

(Infancy) Developing a sense of security and reliability; linked to infant attachment research.

Autonomy vs. Shame and Doubt

(Toddlerhood) Developing independence, self-regulation, and self-efficacy.

Initiative vs. Guilt

(Early childhood) Developing planning skills, imagination, and early foundations of identity.

Industry vs. Inferiority

(School age) Building competence, skills, and self-esteem through achievement.

Identity vs. Role Confusion

(Adolescence) Forming a coherent sense of self and personal identity.

Intimacy vs. Isolation

(Young adulthood) Developing the capacity for close, committed relationships.

Generativity vs. Self-Absorption (Stagnation)

(Middle adulthood) Contributing to society, guiding the next generation, and finding purpose.

Integrity vs. Despair

(Late adulthood) Reflecting on life with acceptance or regret.

Cyclical Nature of Development

Stages influence one another across life; unresolved crises may reappear and require later resolution.

Strengths of Erikson's Theory

Lifespan perspective, emphasis on social and cultural factors, practical applications in education, counseling, and identity research.

Weaknesses of Erikson's Theory

Vague mechanisms of development, limited empirical testing, and potential cultural bias in stage definitions.
