Chapter 5: Theories of Human Development: Sociological and Psychological Perspectives

Theories of Development

Introduction to Developmental Theories

Developmental theories provide frameworks for understanding the physiological, psychological, and behavioral changes that occur throughout the human lifespan. These theories help explain how individuals grow, adapt, and form their personalities in response to various influences, including culture, environment, and social interactions.

• Development involves changes in physiology, cognition, personality, social roles, and emotions across the lifespan.

• Understanding these theories aids in predicting and recognizing behaviors at different life stages.

• Major influences include family, health status, culture, environment, and individual experiences.

Psychoanalytic and Psychodynamic Theories

Psychoanalytic Theory (Freud)

Sigmund Freud's psychoanalytic theory emphasizes the role of unconscious conflicts and psychosexual stages in personality development.

• Conflict arises when societal expectations clash with unconscious desires, leading to anxiety.

• The id (instinctual drives), ego (reality-oriented mediator), and superego (moral conscience) interact to shape behavior.

• Key concepts: Oedipus complex (boys' feelings toward mothers), Electra anxiety (girls' feelings toward fathers).

Defense Mechanisms

• Rationalization: Justifying behaviors with logical reasons.

• Repression: Pushing distressing thoughts into the unconscious.

• Projection: Attributing one's own feelings to others.

• Displacement: Redirecting emotions to a safer target.

• Reaction formation: Behaving in a way opposite to one's feelings.

• Regression: Reverting to earlier developmental behaviors.

• Identification: Adopting characteristics of another person.

• Sublimation: Channeling impulses into socially acceptable activities.

Freud’s Stages of Psychosexual Development

• Oral (0-1 year): Pleasure centers on the mouth.

• Anal (1-3 years): Focus on bowel and bladder control.

• Phallic (3-6 years): Focus on genitals; Oedipus/Electra complex emerges.

• Latency (6-puberty): Dormant sexual feelings.

• Genital (puberty onward): Maturation of sexual interests.

Psychodynamic Theory (Jung)

Carl Jung, a student of Freud, emphasized the importance of the collective unconscious and personality types.

• Did not believe sexuality was the sole basis of behavior development.

• Introduced introvert (inward-focused) and extrovert (outward-focused) personality types.

Psychosocial Theories

Erikson’s Stages of the Life Cycle

Erik Erikson proposed that personality development is shaped by social environment and interactions, with each stage presenting a crisis to be resolved.

• Trust vs. Mistrust (infancy): Developing trust in caregivers.

• Autonomy vs. Shame and Doubt (toddlerhood): Developing independence.

• Initiative vs. Guilt (preschool): Asserting power and control.

• Industry vs. Inferiority (school age): Mastering skills and knowledge.

• Identity vs. Role Confusion (adolescence): Developing a sense of self.

• Intimacy vs. Isolation (young adulthood): Forming intimate relationships.

• Generativity vs. Self-Absorption (middle adulthood): Contributing to society.

• Integrity vs. Despair (late adulthood): Reflecting on life with satisfaction or regret.

Psychosocial Theory (Levinson)

Daniel Levinson expanded on Erikson’s work, emphasizing the sequence of life events and the interplay of environment, culture, and individual choices.

• Life is structured by orderly sequences of events.

• Interactions among environment, culture, and the individual shape development.

Cognitive and Constructive Theories

Cognitive Theory (Piaget)

Jean Piaget focused on cognitive milestones and logical reasoning as key aspects of development.

• Sensorimotor (0-2 years): Learning through senses and actions.

• Preoperational (2-7 years): Developing language and symbolic thinking.

• Concrete Operations (7-11 years): Logical thinking about concrete events.

• Formal Operations (12+ years): Abstract and hypothetical reasoning.

Cognitive Theory (Loevinger)

Jane Loevinger extended Piaget’s model into adulthood, focusing on ego development and critical thinking.

• The ego adapts to demands and supports critical thinking throughout adulthood.

Constructive Theory (Kegan)

Robert Kegan’s constructive developmental theory highlights lifelong interaction with the environment and the balance between relationships and independence.

• Development is shaped by the need for reciprocal relationships and autonomy.

Social and Cultural Theories

Theory of Language and Culture (Vygotsky)

Lev Vygotsky emphasized the importance of social and cultural experiences, especially language, in cognitive and personality development.

• Language is a primary tool for cognitive growth.

• Development is influenced by social interactions at each stage (infant, toddler, preschool, etc.).

Social and Economic Influences (Bronfenbrenner)

Urie Bronfenbrenner’s ecological systems theory explains how social and economic factors shape development through multiple environmental layers.

• Children are influenced by family, school, community, and broader political systems.

• Different environments can lead to different developmental outcomes.

Microsystem	Mesosystem	Exosystem	Macrosystem
Parents, siblings	School, neighborhood	Community, media	Political, cultural context
Teachers, babysitters	Peer groups	Social services	Societal values

Humanistic and Environmental Theories

Hierarchy of Needs (Maslow)

Abraham Maslow’s hierarchy of needs describes the progression from basic physiological needs to self-actualization.

• Individuals must satisfy lower-level needs before achieving higher-level growth.

Level	Description
Physiological	Basic survival needs (food, water, shelter)
Safety and Protection	Security, stability
Love and Belonging	Relationships, affection
Esteem	Self-respect, recognition
Self-Actualization	Personal growth, fulfillment

Environmental Theory (Rogers)

Carl Rogers proposed that individuals naturally strive toward positive outcomes if obstacles are removed, emphasizing the importance of self-concept and mastery over the environment.

• Self-actualization occurs as individuals align with their ideal selves.

• Positive relationships and environmental mastery are crucial for development.

Behaviorist and Social Learning Theories

Behaviorist Theory (Watson, Pavlov, Skinner)

Behaviorist theories focus on the role of the environment and learning in shaping personality and behavior.

• Watson: Personality is molded by environmental experiences.

• Pavlov: Classical conditioning—learning through association.

• Skinner: Operant conditioning—learning through rewards and punishments.

Social-Learning Theories (Bandura and Mischel)

Social learning theories emphasize the importance of observing and imitating others in personality development.

• Behavior is learned through exposure to and imitation of others.

Moral Development and Self-Image

Theory of Moral Development (Kohlberg)

Lawrence Kohlberg described stages of moral reasoning, focusing on how individuals develop a sense of right and wrong.

• Preconventional: Morality based on consequences and self-interest.

• Conventional: Morality based on social rules and approval.

• Postconventional: Morality based on abstract principles and justice.

Development of Self-Image (Cooley and Mead)

Charles Cooley and George Herbert Mead explored how self-image is formed through social interaction, introducing the concept of the "looking-glass self."

• Self-image develops in three steps:

  1. Imagining how we appear to others

  2. Imagining how others evaluate us

  3. Combining these impressions to form a self-concept

Developmental Tasks in Adulthood and Aging

Developmental Tasks of the Older Adult (Peck and Havighurst)

Older adults face unique developmental tasks, including adapting to retirement, health changes, and shifting social roles.

• Peck: Coping with retirement, physiological decline, and mortality.

• Havighurst: Adjusting to health status, income changes, loss of spouse, changing social roles, and living arrangements.

Developmental Stages of Retirement (Atchley)

Robert Atchley identified five stages of retirement adjustment in older adults.

Stage	Description
Preretirement	Planning and anticipation of retirement
Honeymoon	Enjoyment of newfound freedom
Disenchantment	Disappointment or challenges emerge
Stability	Establishing a new routine
Terminal	Decline in health or end-of-life stage

Additional Influences on Growth and Development

• Cultural beliefs and practices: Influence values, behaviors, and expectations.

• Gender differences: Affect developmental experiences and roles.

• Poverty: Impacts access to resources and opportunities.

• Developmental tasks: Vary by life stage and individual circumstances.

Application to Adult Learning and Teaching

Understanding developmental theories enhances the ability to teach individuals at different life stages by recognizing their unique needs, motivations, and challenges. Adult learners are influenced by physiological, cognitive, personality, social, and emotional changes, and effective teaching adapts to these factors.

• Recognize the uniqueness of each learner’s personality and behavior.

• Apply knowledge of developmental stages to support learning and growth.

Example

A teacher working with older adults should consider their need to adapt to retirement, health changes, and evolving social roles, providing support and resources tailored to these developmental tasks.
