Erikson’s Stages of Development

Erik Erikson’s psychosocial development theory outlines eight stages of development that shape our personalities as we grow. Erikson’s theory emphasizes how social interactions and emotional challenges influence us from childhood to adulthood.

In each stage, we face and hopefully overcome different challenges, which helps us grow and mature psychologically. What we learn and experience at one stage lays the groundwork for the next, linking each step of the developmental trajectories together, with each step building on the last.​1​

What are all of Erikson’s stages?

Erikson’s 8 stages of development encompass the following.​2​

Trust versus Mistrust (birth to 1 year)

Babies develop a fundamental sense of trust during infancy as they depend on caregivers to meet their needs. This stage hinges on the reliability of caregiving and the delicate balance between trust and mistrust. Success fosters feelings of trust, while failure leads to anxiety and insecurity in interpersonal relationships and interactions.

Autonomy versus Shame and Doubt (1 to 3 years)

In early childhood, toddlers are at a critical point in developing their independence. This newfound autonomy depends on how parents nurture them, allowing toddlers to make independent choices and explore and tackle tasks on their own. A successful balance between autonomy and shame and doubt in this stage results in a sense of autonomy, while failure can cause feelings of shame and doubt.

Initiative versus Guilt (3 to 6 years)

Preschool children are curious and eager to grasp the world around them, learning to initiate activities and take control of their surroundings. Children assert their power and control over the world through directing play and other social interactions. A healthy balance leads to initiative development, while an imbalance, often due to overly controlling or criticizing caregivers, can result in the child experiencing guilt over their needs and desires. Success in achieving a balance between initiative and guilt leads to a sense of purpose, while failures or excessive reprimanding may instigate a sense of guilt. 

Industry versus Inferiority (6-11 years/puberty)

Children are immersed in the school environment during middle childhood, where they acquire competencies and skills. This stage focuses on their ability to feel competent and productive through learning and creation. Success cultivates a sense of industry, while failures can result in a sense of inferiority.

Identity versus Role Confusion (12–18 years old/adolescence)

Adolescents grapple with establishing their identity, self-exploration, and striving to understand their place in the world. Success in this stage leads to a strong sense of self, while failure can lead to role confusion or identity crisis.

Intimacy versus Isolation (young adulthood)

Young adults seek close and meaningful relationships with others, with this stage marked by the pursuit of love, companionship, and personal connections. Success here results in strong and fulfilling relationships, while setbacks can lead to feelings of isolation.

Generativity versus Stagnation (middle adulthood)

During middle adulthood, individuals channel their energy into creating or nurturing things that will outlive them, such as career accomplishments, raising a family, or contributing to their community. Success leads to a sense of accomplishment, while stagnation may arise from a lack of such contributions.

Integrity versus Despair (late adulthood)

In older age, individuals engage in introspection, reflecting on their life journey. Success in this stage brings a sense of wisdom and fulfillment, while feelings of failure may cause regret, bitterness, and despair as one assesses their legacy.

What is the purpose of Erikson’s 8 stages?

The purpose of Erikson’s 8 stages of psychosocial development is to outline a framework for understanding the growth of the human personality from infancy to late adulthood. Each stage presents a central conflict or developmental task an individual must navigate.

Successfully managing the challenges of each stage leads to a strong and healthy personality. Conversely, difficulties or failure can result in a weakened sense of self and potential problems in future stages.

This framework highlights the influence of social experience across the whole lifespan, suggesting that growth and change continue throughout one’s lifetime. Personal development is not shaped only by early childhood events but also by experiences that occur during adolescence, adulthood, and old age. 

The psychosocial challenge in each stage is a turning point in the development, and the results depend on whether and how a conflict is resolved.

Erikson’s stages help us understand how we understand ourselves and our place in the world. Our experiences and responses in each stage help us grow, learn, and evolve our personality.

This developmental model underscores the importance of social relationships and challenges in shaping a person’s life and psychological well-being.

What happens if you fail Erikson’s stages of development?

Struggles in resolving a developmental stage’s central conflict can lead to imbalances and developmental issues that may affect subsequent stages. 

However, if a person faces challenges in one of Erikson’s stages, there is still potential for resolution later in life. Although these missed developmental milestones can contribute to social and emotional difficulties, they do not preclude emotional growth or the ability to form happy relationships later on.

A key component of Erikson’s theory is the concept of psychosocial regression. 

When a crisis remains unresolved in one stage, individuals might show regressive behaviors associated with that stage when confronted with future stress or conflict. This allows for the possibility of resolution and achieving balance in later life.

Each individual’s life experiences are unique, and environmental factors play a substantial role in a person’s overall development. Encountering challenges in any psychosocial developmental stage suggests an ongoing struggle with the related issue, but it also presents an opportunity for these problems to be confronted and resolved in the future.​3​

Why is Erik Erikson’s theory important?

Erikson’s theory is important because it provides a comprehensive framework for understanding human development throughout the lifespan and a sequence of critical psychological conflicts individuals face at different life stages. This psychosocial theory focuses on social and psychological conflicts and how these impact our growth and understanding of self, relationships, and the world around us. The framework helps understand behavioral patterns and emotional difficulties in child and adolescent psychological development and for therapeutic treatment planning.

What are the similarities and differences between Freud’s and Erikson’s stages of development?

Freud and Erikson both made substantial contributions to theories of development. These influential theories share the following similarities and differences.


  • Influence of the Unconscious – Both theories recognized the importance of the unconscious mind in developing personality.
  • Centered on Conflict – Both Freud and Erikson structured their theories around stages of childhood development characterized by conflicts. In Freud’s theory, these conflicts occur during psychosexual development, while in Erikson’s, they occur during psychosocial development.
  • Impact of Childhood – They both emphasized that experiences in childhood are crucial for personality formation and that unresolved conflicts or trauma during this time can significantly distort personality development​.


  • Focus Area – Freud’s psychosexual stages primarily center around physical pleasure sources, such as sucking and elimination. In contrast, Erikson’s psychosocial stages are more socially and interpersonally oriented, focusing on tasks like forming strong relationships and developing a sense of identity.
  • Stages – The five Freudian stages (Oral, Anal, Phallic, Latent, and Genital) are primarily sexual, while Erikson’s eight stages revolve around social and emotional growth and conflict.
  • Negative Outcomes – In Freud’s view, excessive or insufficient gratification in a stage could lead to ‘fixation,’ where an individual becomes ‘stuck’ in that stage. Conversely, Erikson suggested that failing to complete a stage successfully might not result in fixation but could impair one’s capacity to navigate the next stage effectively, negatively affecting one’s social and emotional development. 
  • Development Continuation – Freud theorized that personality development ends in early adulthood, whereas Erikson believed development continues throughout life.
  • Adversity and Conflict – Erikson’s model offers a more optimistic perspective, suggesting that individuals can resolve conflicts at each stage. In contrast, Freud’s model has a more pessimistic viewpoint, proposing that if experiences during early development cause fixation, this predominantly results in a troubled personality.

Erikson’s developmental stages build on Freud’s ideas, offering a more optimistic view of personal growth. They propose that people can change their paths and influence their futures, even after facing early challenges.

What are the similarities and differences between Erikson’s and Piaget’s theories?


  • Stage Theories – Both developmental theories are based on distinct stages.
  • Fixed Stages – Both theories emphasize that individuals pass through a set sequence of stages, each building on the earlier stages.
  • Similar Ages for Stages – The ages at which children reach certain stages are similar, as is the sequence of developmental events. For example, both theories acknowledge the importance of early reflexes and instinctive behaviors and the development of self-concept during adolescence​​.


  • Focus of Theory – Piaget’s theory centers on cognitive development and how children construct their understanding of the world. In contrast, Erikson’s theory focuses on psychosocial development and identity formation throughout a person’s life.
  • Nature of Development – Piaget’s stages are about cognitive maturation and learning mechanisms, emphasizing how children come to know and understand their world. Erikson’s stages are more about the social and emotional challenges people face at different ages.
  • Stages of Development – Piaget proposed four stages of cognitive development that typically end by adolescence. Erikson outlined eight stages of psychosocial development that extend into late adulthood.
  • Role of Society and Culture – Erikson emphasized the role of culture and society in one’s development, which is less prominent in Piaget’s theory.
  • Adaptation and Ego – While Piaget used biological concepts like assimilation and accommodation to describe cognitive development, Erikson’s theory includes the development of ego identity, influenced by his psychoanalytic background.
  • Life Span Covered – Piaget’s theory primarily covers childhood to adolescence, whereas Erikson’s stages span from infancy to old age.

The two theories differ in their views on human development, with Piaget focusing on the mind’s development and Erikson on social and emotional challenges throughout life.

Which Erikson’s stage relates to the attachment theory?

Erikson’s initial stage, “Trust vs. Mistrust,” which occurs from birth to 18 months, relates most closely to attachment theory. During this infancy stage, the consistency of caregiver responsiveness is critical, and it’s where the foundations of trust are built. 

Secure attachment develops when caregivers provide reliable and nurturing care, leading to an infant’s developing basic trust in the world and a sense of security.

This sense of trust is essential for forming committed relationships later in life, paralleling the secure attachment described by attachment theory, where a child’s early experiences with caregivers shape their expectations and interactions in future social relationships.
