Module 1: Introduction to Human Development
1. Meaning of Human Development
Human development is the scientific study of changes and stability that occur in people from conception till death.
It encompasses three main domains:
Physical Development – Growth of the body, brain, motor skills, health.
Cognitive Development – Mental processes like learning, memory, reasoning, perception, and problem-solving.
Psychosocial Development – Emotions, social interactions, personality, and relationships across life.
2. Principles of Development
Principle of Continuity – Development is continuous and cumulative.
Principle of Individual Development – Every individual develops at a different rate.
Principle of Lack of Uniformity – Growth is not uniform; some skills develop faster, others slower.
Principle of Uniformity of Patterns – Despite differences, developmental stages follow predictable sequences.
General to Specific – Development proceeds from general responses to specific actions.
Cephalocaudal Principle – Development proceeds from head to toe.
Proximodistal Principle – Development proceeds from the center of the body outward.
3. Psychosocial Development (Erik Erikson’s Stages)
Erikson emphasized psychosocial stages across the lifespan, each involving a conflict that must be resolved:
Infancy (0–1 yr): Trust vs. Mistrust
Sense of trust in caregivers vs. fear and insecurity.
Toddlerhood (1–3 yrs): Autonomy vs. Shame & Doubt
Developing independence, self-control vs. doubt in abilities.
Preschool (3–6 yrs): Initiative vs. Guilt
Initiative in planning activities vs. guilt over mistakes.
Middle Childhood (6–12 yrs): Industry vs. Inferiority
Competence and achievement vs. feelings of inferiority.
Adolescence (12–18 yrs): Identity vs. Role Confusion
Developing a sense of self vs. confusion about future roles.
Young Adulthood (18–40 yrs): Intimacy vs. Isolation
Building close relationships vs. loneliness.
Middle Adulthood (40–65 yrs): Generativity vs. Stagnation
Contributing to society and future generations vs. lack of purpose.
Late Adulthood (65+ yrs): Integrity vs. Despair
Acceptance of one’s life vs. regret and despair.
4. Cognitive Development in the Lifespan
Cognition involves learning, memory, reasoning, problem-solving, perception, and mental processes.
Changes occur across life:
Childhood – Rapid cognitive growth, language, reasoning.
Adolescence – Abstract thinking, moral reasoning.
Adulthood – Problem-solving, career-related skills.
Old Age – Decline in processing speed, but wisdom and experience remain strong.
5. Psychosocial Aspects of Development
Social Interactions – Family, peers, and society shape development.
Past Experiences – Influence current behaviors, attitudes, and coping.
Emotions – Emotional regulation improves with age but may decline in late adulthood.
Personality Changes – Personalities evolve with both positive and negative shifts.
6. Levels of Mind (Freudian Perspective)
Conscious – Current awareness and thoughts.
Pre-conscious – Memories not currently active but retrievable.
Sub-conscious/Unconscious – Repressed memories, hidden desires, instincts.
Repression – Unconscious pushing away of painful memories.
Suppression – Conscious decision to avoid thinking about something.
Both good and bad experiences can be suppressed.
7. Methods of Studying Human Development
Longitudinal Studies – Study same individuals over time.
Cross-sectional Studies – Compare different age groups at the same time.
Correlational Studies – Explore relationships between variables.
Experimental Studies – Establish cause-and-effect under controlled conditions.
Case Study Research –
Presenting problem
Case history
Treatment
Result of treatment
Follow-up
Survey Research – Interviews, questionnaires, tests.
Observational Studies –
Naturalistic (real settings)
Laboratory (controlled settings).
8. Key Questions in Human Development
Is development influenced more by genetics (nature) or environment (nurture)?
Do early childhood experiences have the greatest impact, or are later life events equally important?
9. Reflective Application (Personal Growth Example)
Positive Development: Becoming more confident and socially aware post-COVID years by meeting new people, learning psychology’s real-world applications.
Negative/Challenging Experience: ACL surgery leading to scholarship loss and hardship—illustrates how adverse life events shape resilience and coping.
✅ Summary (Quick Revision Points)
Human development covers physical, cognitive, psychosocial changes.
Governed by principles like continuity, individuality, cephalocaudal, Proximodistal.
Erikson’s 8 stages explain psychosocial challenges at each life stage.
Methods include longitudinal, cross-sectional, case study, observation.
Major debates: Nature vs. Nurture, Early vs. Later experiences.
