History & Schools of Psychology – Comprehensive Study Notes

Historical Roots and Ancient Philosophy

• Psychology as a scientific discipline is relatively young—about $125$ years old—but its conceptual roots trace back to antiquity.
• Aristotle ($384-322\,\text{B.C.}$) explored the relationship between soul (psyche) and body in De Anima.
• Plato introduced dualism—the idea that mind and body are separate substances.
• René Descartes ($17^{\text{th}}$-century) agreed with dualism, locating the seat of the soul in the pineal gland.

Transition from Philosophy to Science

• Philosophers debated mind–body relations, while physicians/physiologists studied the brain’s physical structure.
• Convergence of these lines of thought set the stage for laboratory science.

Wilhelm Wundt and Objective Introspection

• In $1879$ (Leipzig, Germany) Wundt ($1832-1920$) founded the first psychological laboratory.
  • Sought to apply scientific methods to study consciousness.
  • Defined mind as an aggregate of thoughts, emotions, experiences, sensations.
• Introduced objective introspection: trained observers examine & measure their own mental processes.
• Published the first psychology journal Philosophische Studien in $1881$.
• Widely regarded as the “Father of Modern Psychology.”

Schools of Thought (Early – Classic)

• Structuralism
• Functionalism
• Gestalt Psychology
• Psychoanalysis
• Behaviorism

Structuralism

• Propagated by Edward Titchener ($1867-1927$), a student of Wundt at Cornell University.
  • Aimed to uncover the structure of the mind by cataloguing basic elements of consciousness (sensations, images, feelings).
  • Utilised introspection for both sensation and thought.
• Margaret Floy Washburn (Titchener’s student) became the first woman Ph.D. in Psychology ($1894$) and authored The Animal Mind ($1908$).
• Declined in early $1900\text{s}$ due to internal disputes over which elements were fundamental.

Functionalism

• Founded by William James in the $1870\text{s}$ at Harvard.
  • Viewed consciousness as an ever-changing stream; once examined, it changes.
  • Influenced by Darwin’s theory of natural selection.
• Focus: how consciousness functions to help organisms adapt, work, play in real-world environments.
• Mary Whiton Calkins completed Ph.D. requirements but was denied the degree by Harvard because of her gender.
• Comparison:
  • Structuralism = “what the mind is.”
  • Functionalism = “what the mind does.”

Behaviorism

• Founded by John B. Watson (early $20^{\text{th}}$ century).
  • Re-emphasised scientific inquiry and observable behavior only.
  • Humans are like machines controlled by external stimuli; environment shapes behavior.
  • To understand a person, analyze the external factors (stimulus conditions) influencing them.

Psychoanalysis

• Developed by Sigmund Freud (neurologist).
  • Proposed an unconscious mind that stores repressed urges & desires.
  • Claimed humans share animalistic drives toward sexual gratification & aggression yet remain unaware of them.
  • Stressed childhood experiences as determinants of personality.
  • Followers: Alfred Adler, Carl Jung, Erik Erikson, Anna Freud.

Freud’s Tripartite Personality Structure

• Id
  • Governed by Pleasure Principle; seeks immediate gratification.
  • Narcissistic, amoral, asocial—“the animal within.”
  • Examples: newborns, criminals.
• Ego
  • Operates on Reality Principle; mediates id & external world.
  • Accesses unconscious content, delays gratification, negotiates compromises.
  • Traits: well-adjusted, mature, sociable.
• Superego
  • Morality Principle; internalized societal norms.
  • Demands perfection—“society within.”
  • Two subsystems:
  • Ego-Ideal (rewards/pride)
  • Conscience (punishments/guilt)
• Diagrammatic layout (levels of awareness):
  • $\text{Conscious} \rightarrow \text{Preconscious} \rightarrow \text{Unconscious}$
  • Psychic energy originates in the unconscious id; ego & superego integrate social reality.

Gestalt Psychology

• Founded by Max Wertheimer.
  • “Gestalt” = good form/figure; also termed field theory.
  • Physics & philosophy influenced its holistic stance.
• Key tenets:
  • Experience is an interrelated whole; “the whole is greater than the sum of its parts.”
  • Perception involves pattern seeking; one “field” of experience affects another.

Humanistic Psychology (Third Force)

• Emerged as reaction to Freud (pessimism) & Watson (mechanism).
• Core assumptions:
  • Humans are conscious, creative, unique, and free agents—neither animals nor machines.
  • Aim for self-actualization: realizing full potential, leading rich & meaningful lives.
• Key figures: Abraham Maslow & Carl Rogers.

Maslow’s Hierarchy of Needs

• Pyramid-shaped progression (lower ➜ higher):
  1. Physiological Needs
  2. Safety & Security
  3. Love & Belongingness
  4. Self-Esteem
  5. Cognitive Needs
  6. Aesthetic Needs
  7. Self-Actualization (highest)
• Graphically: $\text{Physiological} \rightarrow \text{Safety} \rightarrow \text{Love} \rightarrow \text{Esteem} \rightarrow \text{Cognitive} \rightarrow \text{Aesthetic} \rightarrow \text{Self-Actualization}$

Three Pillars Comparison

• Psychoanalysis (Freud): people ≈ animals driven by instincts.
• Behaviorism (Watson): people ≈ machines molded by environment.
• Humanism (Maslow/Rogers): people are free agents capable of growth.

Modern Perspectives (Post-1950s to Present)

• Humanistic Psychology (covered above)
• Biopsychological Perspective
  • Behavior & cognition arise from biological events: hormones, neurotransmitters, tumors, diseases.
• Cognitive Perspective
  • Studies thinking, memory, language, problem-solving.
  • Became a major force in the $1960\text{s}$ (cognitive revolution).
• Sociocultural Perspective
  • Integrates Social Psychology (groups, roles) and Cultural Psychology (norms, values).
  • Reminds us behavior varies with social context and cultural background.
• Evolutionary Perspective
  • Explains universal mental traits (lying, fear, mate preferences) via natural selection.
  • Mind viewed as information-processing machinery shaped during hunter-gatherer era.

Recent Interdisciplinary Developments

• Information-Processing Models (Herbert Simon): mind likened to computational system.
• Modern Linguistics (Noam Chomsky): innate mental structures enable language acquisition.
• Neuropsychology: correlates brain events with mental processes using imaging & lesion methods.

Changing Definitions of Psychology Over Time

• Wundt era: “science of mental life.”
• Behaviorist era ($1920-1960$): “science of behavior.”
• Modern era (post-$1960$): science of behavior and mental processes (both conscious & unconscious).

Practical / Ethical / Philosophical Implications

• Dualism vs. monism continues to influence debates on consciousness, AI, and mind-uploading.
• Behaviorism raised ethical issues about manipulation through conditioning.
• Psychoanalytic emphasis on childhood informs therapeutic practices but faces falsifiability critiques.
• Humanistic focus on self-actualization underlies positive psychology and organizational leadership programs.
• Biopsychological & evolutionary views guide medical treatments, yet spark debates on determinism and reductionism.
