4.1 Growth and Development (Erikson/Piaget)
Key Takeaways
Erik Erikson's 8 stages of psychosocial development span from birth to death, each presenting a crisis that must be resolved for healthy personality development
Jean Piaget's 4 cognitive stages progress from sensorimotor (0-2 years) through formal operational (12+ years), describing how children develop logical thinking
Trust vs. Mistrust (infancy) is the foundation of all future development - consistent, responsive caregiving builds trust
Adolescents in Identity vs. Role Confusion focus on peer acceptance, body image, and establishing independence
Understanding developmental stages helps nurses provide age-appropriate education and anticipatory guidance
Growth and Development Theories
Understanding human development is essential for nursing practice. Two foundational theories guide how nurses assess clients and plan age-appropriate care: Erik Erikson's psychosocial development and Jean Piaget's cognitive development.
Why Development Matters for Nurses
Nurses use developmental knowledge to:
- Assess appropriateness - Is this child meeting expected milestones?
- Educate effectively - Match teaching methods to cognitive abilities
- Anticipate concerns - Guide parents on upcoming developmental challenges
- Identify delays - Recognize when referrals are needed
Erik Erikson's Stages of Psychosocial Development
Erik Erikson described eight stages of development, each centered on a psychosocial crisis. Successfully resolving each crisis leads to a virtue; failure creates difficulties in later stages.
| Stage | Age | Crisis | Virtue | Key Focus |
|---|---|---|---|---|
| 1 | 0-1 year | Trust vs. Mistrust | Hope | Consistent caregiving |
| 2 | 1-3 years | Autonomy vs. Shame/Doubt | Will | Self-control, independence |
| 3 | 3-6 years | Initiative vs. Guilt | Purpose | Exploration, imagination |
| 4 | 6-12 years | Industry vs. Inferiority | Competence | Achievement, skill-building |
| 5 | 12-18 years | Identity vs. Role Confusion | Fidelity | Self-identity, peer group |
| 6 | 18-35 years | Intimacy vs. Isolation | Love | Close relationships |
| 7 | 35-65 years | Generativity vs. Stagnation | Care | Contributing to society |
| 8 | 65+ years | Integrity vs. Despair | Wisdom | Life review, acceptance |
Nursing Implications by Stage
Trust vs. Mistrust (Infancy)
- Respond promptly to infant cries
- Maintain consistent routines
- Encourage parental bonding
- Explain to parents that "spoiling" an infant is not possible
Autonomy vs. Shame and Doubt (Toddler)
- Offer simple choices ("Red cup or blue cup?")
- Allow safe exploration
- Expect negativism ("No!") as developmentally normal
- Use positive reinforcement for toilet training
Initiative vs. Guilt (Preschool)
- Encourage imaginative play
- Answer "why" questions patiently
- Provide safe boundaries for exploration
- Recognize magical thinking is normal
Industry vs. Inferiority (School-Age)
- Praise effort and accomplishments
- Support academic and social development
- Encourage participation in groups/teams
- Help children develop real skills
Identity vs. Role Confusion (Adolescence)
- Respect privacy and growing independence
- Provide health education without judgment
- Recognize peer influence is paramount
- Support identity exploration
Jean Piaget's Stages of Cognitive Development
Jean Piaget described how children develop logical thinking through four stages. Each stage represents a qualitatively different way of understanding the world.
| Stage | Age | Key Characteristics | Limitations |
|---|---|---|---|
| Sensorimotor | 0-2 years | Learns through senses and actions; develops object permanence | No symbolic thought yet |
| Preoperational | 2-7 years | Symbolic thinking (language, pretend play); egocentric | Cannot think logically; centration |
| Concrete Operational | 7-11 years | Logical thinking about concrete objects; conservation | Cannot think abstractly |
| Formal Operational | 12+ years | Abstract and hypothetical thinking | Not all adults achieve fully |
Key Concepts Explained
Object Permanence (Sensorimotor)
- Understanding that objects exist even when not visible
- Develops around 8-12 months
- Before this: "out of sight, out of mind"
- Nursing tip: Separation anxiety peaks after object permanence develops
Egocentrism (Preoperational)
- Inability to see others' perspectives
- Child believes everyone thinks like they do
- Not selfishness - a cognitive limitation
- Nursing tip: Preschoolers may believe illness is punishment
Animism (Preoperational)
- Belief that inanimate objects are alive
- "The tree is sad" or "My teddy feels cold"
- Use this therapeutically: dolls for procedure teaching
Conservation (Concrete Operational)
- Understanding that quantity remains constant despite appearance changes
- Classic test: Equal water in different-shaped glasses
- Achieved around age 7
On the Exam
Expect questions asking you to:
- Match behaviors to appropriate developmental stages
- Identify age-appropriate nursing interventions
- Recognize developmental red flags
- Apply theory to clinical scenarios
Comparing Erikson and Piaget
| Age | Erikson (Psychosocial) | Piaget (Cognitive) |
|---|---|---|
| Infant | Trust vs. Mistrust | Sensorimotor |
| Toddler | Autonomy vs. Shame/Doubt | Preoperational (early) |
| Preschool | Initiative vs. Guilt | Preoperational |
| School-Age | Industry vs. Inferiority | Concrete Operational |
| Adolescent | Identity vs. Role Confusion | Formal Operational |
Clinical Application
When caring for a 4-year-old (preschool):
- Erikson: Support initiative - encourage questions, allow choices
- Piaget: Preoperational - use concrete language, expect magical thinking
Exam Tips
- Erikson focuses on SOCIAL/EMOTIONAL development (crises, relationships)
- Piaget focuses on COGNITIVE development (thinking, reasoning)
- Memorize age ranges and key characteristics for each stage
- Trust vs. Mistrust is tested frequently - emphasize consistent caregiving
- Object permanence (8-12 months) relates to separation anxiety timing
A 2-year-old child repeatedly says "No!" when asked to do something. According to Erikson, this behavior indicates which developmental stage?
Trust vs. Mistrust
Autonomy vs. Shame and Doubt
Initiative vs. Guilt
Industry vs. Inferiority
A nurse is preparing to teach a 5-year-old about an upcoming procedure. Based on Piaget's stages, which approach is most appropriate?
Provide detailed written instructions for the child to read
Explain the abstract concept of why the procedure is necessary
Use a doll to demonstrate the procedure concretely
Discuss hypothetical scenarios about what might happen
According to Piaget, at what age does a child typically develop object permanence?
2-4 months
8-12 months
18-24 months
3-4 years
