Human Development

Development is a process of progressive, orderly, and predictable changes that begin at conception and continue throughout life.

Differences:

Feature	Growth	Maturation	Development
Definition	Quantitative increase in size (height, weight).	Biological unfolding of genetic blueprints (e.g., puberty).	Qualitative and quantitative changes in the whole person.
Duration	Stops at maturity.	Automatic; follows a biological clock.	Lifelong (Womb to Tomb).

The Life-Span Perspective (Paul Baltes) views development as:

• Lifelong: It takes place across all age groups (no single age is dominant).
• Multi-directional: Some dimensions grow while others decline (e.g., wisdom increases, running speed decreases).
• Plastic: Capabilities are modifiable (e.g., memory skills can be improved in old age).
• Contextual: Influenced by historical, social, and cultural contexts.

Developmental Tasks are specific challenges or skills that arise at a certain period in an individual’s life. Successful achievement leads to happiness and success in later tasks.
Examples:

• Infancy: Learning to walk, eat solid food, and talk.
• Adolescence: Achieving emotional independence from parents; preparing for a career.
• Adulthood: Finding a partner; civic responsibility.

• Nutrition: A child with genes for tall height will not grow tall if malnourished.
• Stimulation: Children in stimulating environments (books, conversation) develop higher IQs than those in deprived settings.
• Parenting: A secure and loving home fosters emotional stability, while a hostile environment breeds anxiety.

Development is socially mediated (Vygotsky).

• Cultural Tools: Children learn through the language and number systems of their culture.
• Social Values: In individualistic cultures (West), children are taught independence. In collectivist cultures (India), they are taught interdependence. This shapes their personality and worldview.

According to Jean Piaget, cognitive development occurs in stages: [Image of Piaget stages of cognitive development]

• Sensorimotor (0-2 yrs): Object Permanence (knowing objects exist even when unseen).
• Pre-operational (2-7 yrs): Symbolic thinking, but marked by Egocentrism (inability to see others’ views) and Animism.
• Concrete Operational (7-11 yrs): Logical thinking about physical objects; understanding Conservation.
• Formal Operational (11+ yrs): Abstract, hypothetical, and deductive reasoning.

Attachment (Bowlby) is the emotional bond between infant and caregiver.

• Secure Attachment: Infants who feel safe with caregivers grow into adults who trust others and form healthy relationships.
• Insecure Attachment: Infants who experience neglect or inconsistent care often develop anxiety, trust issues, or avoidance in adult relationships.

Adolescence is the transitional period between childhood and adulthood (approx. 11-19 years).
Adolescent Egocentrism (David Elkind):

• Imaginary Audience: The belief that they are constantly being watched and judged by others (e.g., “Everyone is staring at my pimple”).
• Personal Fable: The belief that they are unique and invincible (e.g., “Accidents happen to others, not me”).

Identity formation (Erikson’s Identity vs Role Confusion) involves answering “Who am I?”.
Factors:

• Family: Democratic parenting helps exploration; rigid control hinders it.
• Peers: Friends provide a mirror for self-evaluation and validation.
• Career/Education: Choosing a path shapes one’s future self-concept.

Early adulthood (20s-30s) brings the crisis of Intimacy vs Isolation.

• Career Establishment: Finding a job, financial independence, and proving competence.
• Marriage/Partnership: Forming a committed, long-term relationship.
• Parenthood: Adjusting to the immense responsibility of raising a new generation.

(Analysis for Self-Reflection)

• Common Problems: Generation gap issues like dressing sense, use of mobile phones, career choices, or friends.
• Resolutions: Often solved through intervention by a cooler relative (aunt/uncle) or eventually talking it out.
• Better Ways: Active listening, using “I feel” statements instead of “You always,” and seeking compromise rather than winning the argument.

Preoperational Child (4-7 years):
Script: “I am the superhero! You are the bad guy. No, you have to fall down when I say ‘Boom’!”
Features: Egocentric (my rules matter most), Parallel play, Symbolic/Pretend play.

Adolescent:
Script: “Hey, do you guys want to go to the mall? Or we could game online? What does everyone feel like doing?”
Features: Social Conformity, Cooperative decision making, Concern with peer approval and identity.
