What is the Erikson’s Psychosocial Theory and its Importance?

Erik Erikson, a German psychologist, proposed that individuals experience a distinct psychosocial struggle during each of the eight stages of their lives, which significantly shape their personality as they develop. This theory, known as the eight stages of development theory, provide insights into social and psychological growth and evaluate the influence of relationships in various life stages (Brennan, 2021).

Erikson’s 8 Stages of Psychosocial Development

Erikson’s theory posits that ego identity develops continuously throughout life across these eight specific stages:

stages of psychosocial development

First stage – Infancy (Birth to 18 months)

According to Erik Erikson’s theory of psychosocial development, the first stage, which spans from birth to approximately 18 months. In this stage babies often feel conflict between “trust and mistrust”.

During infancy, babies depend entirely on their caregivers, typically their parents, for their basic needs, such as food, comfort, and security. Erikson believed that how these needs are met during this early stage of life profoundly influences an individual’s development and personality.


If infants receive consistent care, love, and attention from their caregivers, they develop confidence. They learn to rely on their caregivers to meet their needs, and this trust forms the foundation for healthy social and emotional development. Babies who feel secure and loved are more likely to develop confidence in themselves and others as they grow.


On the other hand, if caregivers are inconsistent, neglectful, or fail to meet the baby’s needs promptly and with care, the infant may develop a sense of mistrust. They may become anxious and uncertain about whether their needs will be met, leading to a lack of confidence in themselves and others. This can have long-lasting effects on their ability to form healthy relationships and trust in the world around them.

Successful resolution of the Trust versus Mistrust stage lays the groundwork for a more positive and confident approach to the subsequent stages of psychosocial development. Caregivers need to provide a safe and nurturing environment for infants, as the experiences during this stage can significantly influence a person’s overall well-being and ability to form healthy relationships throughout life.

Second stage -Toddlerhood (18 months to 2-3 years)

 The stage of toddlerhood, which typically spans from around 18 months to 2-3 years of age, is in the conflict between “autonomy and shame and doubt”.

During toddlerhood, children assert their independence and actively explore their environment. They develop a sense of self and start making choices and decisions, especially in areas like dressing, feeding, and toilet training. This stage is crucial for developing a child’s self-concept and ability to navigate the world with a growing sense of autonomy.


Successful resolution of this stage results in the development of independence. Toddlers encouraged by their caregivers to explore, make choices, and take on age-appropriate responsibilities begin developing self-confidence and independence. They learn that they can have some control over their lives, and this autonomy is essential for healthy psychosocial development. It helps them develop a sense of self-worth and the ability to take initiative.

Shame and Doubt

On the other hand, the child may develop shame and doubt if caregivers are overly restrictive or critical or do not allow the toddler to take on age-appropriate responsibilities. They may become unsure of their abilities and hesitant to try new things. This can lead to a lack of self-esteem and self-doubt, which can persist into later stages of development and affect their willingness to take risks and explore the world around them.

It’s crucial for caregivers during this stage to provide a balance between allowing the child to explore and make choices while also setting appropriate boundaries and giving guidance. This helps toddlers develop a healthy sense of autonomy while feeling secure and supported.

Successful resolution of the Autonomy versus Shame and Doubt stage contributes to a child’s growing sense of self and ability to navigate future challenges with confidence and a positive self-image. It lays the foundation for the following stages of psychosocial development.

Third stage – Preschool (3 to 5 years)

The preschool stage, which typically spans from ages 3 to 5 years, is characterized by the conflict between initiative and guilt. This stage is often referred to as “Initiative versus Guilt.”

During preschool, children continue to develop their sense of self and interact with the world around them. They become more curious, imaginative, and socially active, exploring their environment and interacting with others more extensively.


Successful resolution of this stage results in the development of the industry. Preschoolers are encouraged to explore their interests, express their ideas, and take on new challenges to develop a sense of purpose and ambition. They become more proactive in pursuing their goals and interests, showing enthusiasm for learning and trying new activities. This sense of initiative helps build their self-confidence and a positive outlook on their abilities to make things happen.


On the other hand, if children’s attempts at taking the initiative are met with criticism, overly strict limitations, or a sense of wrongdoing from caregivers, they may develop guilt. These feelings of guilt can emerge if children believe their actions have caused harm or displeasure to others. This guilt can hinder their willingness to take on new challenges and may lead to anxiety about their actions and choices.

During the preschool years, caregivers play a crucial role in supporting children’s curiosity and encouraging their initiative while setting appropriate boundaries and helping them understand the consequences of their actions.

Successful resolution of the Initiative versus Guilt stage contributes to a child’s growing sense of competence, purpose, and self-esteem. It lays the foundation for their willingness to explore and learn throughout their development and influences their ability to take on new challenges and interact with others positively.

Fourth stage – Early School Years (6 to 11 years)

The stage of the early school years spans from around age 6 to 11 years and is characterized by the conflict between industry and inferiority. This stage is often referred to as “Industry versus Inferiority.”

During the early school years, children become more focused on their interactions with peers and their learning experiences in school. They acquire new skills, knowledge, and competencies and seek recognition and validation from their teachers, peers, and caregivers.


Successful resolution of this stage results in the development of industry. Children who are encouraged and supported to acquire new skills, work hard, and achieve competence in various areas develop a sense of initiative. They take pride in their accomplishments, become more self-disciplined, and are motivated to learn and succeed. Positive reinforcement and encouragement from teachers and parents play a significant role in fostering this sense of industry.


On the other hand, if children experience consistent setbacks, failures, or negative feedback in their efforts to learn and master new skills, they may develop feelings of inferiority. These feelings of inadequacy and incompetence can erode their self-esteem and confidence. Children who perceive themselves as inferior to their peers may become discouraged and avoid challenges, leading to a sense of inferiority that can persist into later stages of development.

During the early school years, caregivers and educators must provide opportunities for children to explore their interests, learn new skills, and experience success. Positive reinforcement and constructive feedback can boost a child’s sense of industry and encourage them to take initiative in their learning.

Successful resolution of the Industry versus Inferiority stage contributes to a child’s growing sense of competence, productivity, and self-esteem. It shapes their attitudes toward learning and achievement, impacting their motivation and willingness to face challenges throughout their academic and social development.

Fifth stage – Adolescence (12 to 18 years)

The stage of adolescence spans from approximately age 12 to 18 years and is characterized by the conflict between identity and role confusion. This stage is often referred to as “Identity versus Identity Confusion.”

Adolescence is a period of significant psychological and social growth, marked by the transition from childhood to Adulthood. During this stage, individuals grapple with questions about their sense of self, identity, and role in society.


Successful resolution of this stage results in developing a solid and cohesive identity. Adolescents who explore their values, beliefs, interests, and life goals and successfully integrate these aspects into a consistent and meaningful self-concept develop a strong sense of identity. They clearly understand who they are, what they stand for, and where they fit in the world. This sense of identity gives them a stable foundation to build their future.

Identity Confusion

Conversely, if adolescents struggle to explore their identity or cannot reconcile conflicting aspects of themselves, they may experience identity confusion. This can manifest as uncertainty about one’s values, beliefs, career goals, or social roles. Adolescents who must establish a clear sense of self may feel lost, aimless, or disconnected from their peers and society.

During adolescence, individuals engage in self-discovery and experimentation, seeking to answer questions about their identity, including their values, career aspirations, relationships, and personal beliefs. It is a period of significant self-reflection and exploration, often involving testing various roles and identities.

Support from caregivers, peers, and mentors is essential during this stage. Adolescents benefit from guidance that encourages healthy exploration and self-expression while providing a safe environment to navigate identity formation challenges.

Successful resolution of the Identity versus Identity Confusion stage lays the groundwork for a stable and confident sense of self, setting the stage for future phases of development, including young Adulthood. Adolescents who emerge from this stage with a clear identity are better equipped to make informed decisions, pursue their goals, and establish meaningful relationships as they transition into Adulthood.

Sixth stage – Young Adulthood (19 to 40 years)

Young Adulthood is a stage that typically spans from around age 19 to 40. This stage is characterized by the conflict between intimacy and isolation, often called “Intimacy versus Isolation.”

During young Adulthood, individuals face several significant challenges and opportunities as they transition from adolescence to full-fledged Adulthood. This stage involves various aspects of personal development, relationships, and life choices.


Successful resolution of the Intimacy versus Isolation stage results in the development of intimacy. Young adults who can establish and maintain close, meaningful, and loving relationships with others experience intimacy. These relationships can include romantic partnerships, close friendships, and deeper connections with family members. Intimacy involves emotional closeness, trust, and a willingness to be vulnerable with others. Individuals who achieve intimacy in their relationships tend to experience a sense of fulfillment and connection.


On the other hand, if young adults struggle to form close relationships or fear vulnerability and emotional connection, they may experience isolation. This can manifest as a sense of loneliness and disconnection from others. Individuals who feel isolated may have difficulty forming close bonds and avoid meaningful relationships, leading to emptiness and emotional distance from others.

During young Adulthood, individuals often explore various aspects of their lives:

1. Career and Education

Young adults typically make essential decisions about their education and career paths, seeking to establish themselves in the workforce or pursue further education and training.

2. Relationships

This stage often involves pursuing romantic relationships, marriage, and starting families. It is a time when individuals work on building and maintaining long-term partnerships and often face the challenges of balancing individuality with commitment.

3. Identity and Values

Young adults continue to develop their sense of identity, exploring their values, beliefs, and life goals. They may grapple with questions about their purpose and discounts in the context of adult responsibilities.

Independence and Autonomy

Achieving independence and autonomy from one’s family of origin is crucial to this stage. Young adults seek to establish their own households, financial freedom, and decision-making abilities.

Supportive relationships, self-discovery, and a healthy balance between independence and connection are essential during this stage. Young adults benefit from opportunities for personal growth, self-exploration, and the ability to form and maintain intimate relationships with others.

Successful resolution of the Intimacy versus Isolation stage sets the foundation for healthy adult relationships and contributes to overall emotional well-being. Young adults who can establish meaningful connections with others are better equipped to navigate the challenges of Adulthood, find fulfillment in their personal and social lives, and continue their development into subsequent stages of life.

Seventh stage – middle Adulthood

 Middle Adulthood typically spans from around age 40 to 65 and is characterized by the conflict between generativity and stagnation or self-absorption. This stage is often referred to as “Generativity versus Stagnation.”

Middle Adulthood is when individuals face unique challenges and opportunities related to their personal and social lives, careers, and societal contributions.


Successful resolution of the Generativity versus Stagnation stage results in the development of generativity. Middle-aged adults who experience generativity are actively engaged in nurturing and contributing to the well-being of future generations. This may involve raising children, mentoring others, participating in community activities, and pursuing careers that positively impact society. Generativity is characterized by a sense of care, responsibility, and a desire to leave a lasting legacy. It reflects a broader concern for the welfare and development of others.

Stagnation or Self-absorption

On the other hand, if middle-aged individuals fail to find meaningful ways to contribute to society or become self-absorbed and disengaged, they may experience stagnation. Stagnation can manifest as a sense of emptiness, a lack of purpose, and feeling disconnected from others and society. Individuals in this state may become preoccupied with their own needs and desires, neglecting opportunities to positively impact the world around them.

During middle Adulthood, individuals often confront a variety of challenges and life transitions:

Career and Achievement

Middle-aged adults may reassess their career goals, seek new opportunities, or reflect on their achievements and contributions to their field.

Parenting and Family

This stage often involves the experience of parenting adolescents or young adults. It can also include becoming empty nesters as children leave home.

Health and Aging

Middle-aged individuals may become more aware of their physical and health-related changes as they age. They may focus on maintaining a healthy lifestyle and addressing health concerns.


Marital relationships may evolve, and individuals may face challenges maintaining long-term partnerships. Friendships and social connections have become increasingly important.

Legacy and Impact

Individuals may contemplate their heritage in terms of their family and their contributions to society. They may seek ways to make a positive impact on future generations.

Supportive relationships, a sense of purpose, and opportunities for continued personal and professional growth are crucial during middle Adulthood. Middle-aged adults benefit from finding meaningful ways to give back to their communities and engage in activities that align with their values and aspirations.

Successful resolution of the Generativity versus Stagnation stage fosters a sense of fulfillment, connectedness, and the knowledge that one is making a positive difference in the world. It contributes to overall well-being and prepares individuals for the challenges and opportunities of late Adulthood.

Eighth stage – Late Adulthood (Age 65  and beyond)

late Adulthood encompasses the set typically beginning at around age 65 and extending throughout an individual’s life. This stage is characterized by the conflict between ego integrity and despair, often called “Ego Integrity versus Despair.”

Late Adulthood is a period of reflection and contemplation as individuals navigate the challenges and opportunities associated with aging and the culmination of their life experiences.

Ego Integrity

Successful resolution of the Ego Integrity versus Despair stage results in the development of ego integrity. Late adults who achieve ego integrity have a sense of wholeness and completeness. They reflect on their life journey with acceptance, contentment, and fulfillment. They recognize the value of their experiences, both positive and negative, and have a deep understanding of the meaning of their life. Ego integrity is characterized by a sense of wisdom, acceptance of mortality, and an ability to face the end of life with grace and dignity.


If late adults struggle to find meaning and acceptance in their life’s journey or become overwhelmed by regrets and missed opportunities, they may experience pain. Despair can manifest as bitterness, disappointment, and a feeling of wasted energy. Individuals in this state may grapple with fear of death and unresolved conflicts, leading to a sense of hopelessness and sadness.

During late Adulthood, individuals encounter various challenges and life changes:

Physical Health

Late adults may experience age-related health issues and limitations. They often focus on maintaining their physical and mental well-being through healthy lifestyle choices and medical care.

Loss and Grief

Loss of loved ones, including friends and family members, is expected during this stage. Late adults may also confront their own mortality and contemplate their legacy.


Late Adulthood may involve adapting to changes in social roles and relationships, including retirement, relocation, and caregiving responsibilities.

Reflection and Legacy

Individuals may reflect on their life’s accomplishments, values, and the impact they have had on others. They may seek to leave a lasting legacy for future generations.

Spirituality and Meaning

Many late adults explore their spirituality and seek more profound meaning. They may use religion, philosophy, or personal beliefs for solace and purpose.

Social support, a sense of meaning and purpose, and opportunities for continued engagement and connection with others are essential during late Adulthood. Late adults benefit from having a supportive network, engaging in meaningful activities, and addressing unresolved issues from their past.

Successful resolution of the Ego Integrity versus Despair stage allows individuals to embrace their life journey with wisdom, acceptance, and serenity. It enables them to face the end of life with dignity and a deep appreciation for the richness of their experiences, contributing to overall emotional well-being and fulfillment in late Adulthood.

Criticisms of Erikson’s Theory

Several critics have challenged Erikson’s Theory of psychosocial development, as indicated by scholars such as Marcia (2010), McCrae & Costa (1997), Brown & Lowis (2003), and Orenstein (2020). These criticisms include the following points: 

  • The sequential order of the stages may not always occur as described.
  • The age ranges assigned to each stage may be inaccurate.
  • Stage eight implies a transition from activity to passivity, which contradicts the continued productivity and community involvement of many individuals in their later years.
  • The quest for identity may recur at various points in our lives, not solely during adolescence.
  • The developmental processes within each stage remain unclear.
  • The resolution of conflicts and progression to the next stage may not be driven by a single, universal mechanism.
  • The definition of success is subjective, varying among individuals, cultures, and evolving within individuals over time.
  • The means to resolve such conflicts in later life are not clearly elucidated.

Erikson himself, in his work “Insight and Responsibility” from 1964, acknowledges some of these criticisms and suggests that his theory provides a descriptive overview of psychosocial development without delving into the specific mechanisms or steps involved.
