Notes on History of Psychology

William James

  • Considered the father of American psychology.

  • One of the first advocates of functionalism in psychology.

  • Developed the James-Lange theory which posits that emotions arise from awareness of physiological states.

  • Distinguished between two parts of consciousness:

    • Transitive parts that refer to other elements in the stream of thoughts.

    • Substantive parts where one can focus and feel a sense of permanence.

Functional Psychology

  • Functionalism seeks to understand mental life and behavior in terms of active adaptation to the environment.

  • Emerged in the U.S. in the late 19th century as an alternative to structuralism.

  • While not a formal school, it laid the groundwork for later psychological theories.

  • Strong relationship exists between functionalism and pragmatism in philosophy.

John Dewey (Pragmatist)

  • Made significant contributions to learning theory, emphasizing active learning and direct experience in education.

  • Published "School and Society" and founded a pedagogical laboratory.

  • Stressed the importance of the scientific method in psychology and education.

  • Critiqued philosophers for neglecting mental functions that constitute thought itself.

Pragmatism

  • A philosophical movement from the 19th century suggesting that thought’s primary function is prediction and action, rather than reality representation.

  • Knowledge is considered true based on its practical consequences.

  • Key founder: Charles Sanders Pierce.

Edward Lee Thorndike (Functionalist/Behaviorist)

  • Proposed that animals learn mechanically.

  • Suggested learning involves connections between stimulus and response.

Sigmund Freud (Psychoanalyst)

  • Regarded as the father of psychoanalysis.

  • Developed the defense mechanisms and psychosexual development theory.

Psychoanalysis
  • A theory explaining human behavior based on analysis of sexual conflicts originating from childhood.

  • Instinctual impulses repressed by consciousness remain in the unconscious, affecting the individual.

  • Psychoanalyst must interpret dreams, failures, and free association to reveal unconscious conflicts.

  • Freud’s model of the mind:

    • Id (El Ello): Operates unconsciously, seeking pleasure/instincts (Eros - life instincts, Thanatos - death instincts).

    • Ego (El Yo): Develops in childhood, balances the id’s demands with social reality.

    • Superego (El Super-Yo): Enforces moral standards, inducing guilt for not adhering to norms.

Defense Mechanisms
  • Incorrect ways to resolve psychological conflict, potentially leading to mental disorders.

Psychosexual Theory
  1. Oral Stage: Birth to 18 months - pleasure focuses on the mouth.

  2. Anal Stage: 18 months to 3 years - control over bodily functions becomes central.

  3. Phallic Stage: 3 to 6 years - genital focus and interest in sexual differences.

  4. Latency Stage: 6 years to puberty - focus on learning and social interaction.

  5. Genital Stage: Puberty onwards - sexual curiosity and exploration.

Dream Analysis
  • Dreams reveal unconscious desires while defenses are down.

  • Manifest content: the surface narrative of dreams.

  • Latent content: the hidden meaning behind the dream.

Edmund Husserl (Phenomenologist)

  • Founder of transcendent phenomenology.

  • Authored "Philosophy of Arithmetic", focusing on numerical symbols.

Phenomenology
  • Seeks to renew philosophy by reconnecting with science, analyzing mental phenomena as they occur in consciousness.

Max Scheler (Phenomenologist)

  • Used phenomenology to study emotional phenomena and their intentionality.

  • Developed the sense theory of suffering, suggesting pain must serve a purpose.

Behaviorism

  • Focuses on observable behavior rather than intrapsychic factors.

  • Studies laws governing human/animal behavior.

Key Terms in Behaviorism
  1. Stimulus: Any signal or event provoking an organism's reaction.

  2. Response: The organism's reaction to a stimulus.

  3. Conditioning: Learning through stimulus-response associations.

  4. Reinforcement: Consequence enhancing the likelihood of a behavior.

  5. Punishment: Consequence that reduces a behavior's occurrence.

Key Figures in Behaviorism

  • Conwy Lloyd Morgan: Differentiated instinctual vs learned reactions in animals; proposed the law of parsimony.

  • Ivan Pavlov: Experiments leading to classical conditioning concepts.

  • John B. Watson: Conducted the "Little Albert" experiment to demonstrate learned fears through conditioning.

  • Burrhus F. Skinner: Advocated for operant conditioning; used Skinner boxes for his experiments on reinforcement.

Donald Hebb (Neo-Functionalist)

  • Considered the father of psychobiology, laid foundations for modern neurology.

  • Proposed that synaptic connections strengthen when neurons fire together.

Jean Piaget (Cognitivist/Developmental Psychologist)

  • Father of genetic epistemology, developed cognitive-evolutionary theory, outlining developmental stages.

Abraham Maslow (Humanist)

  • Created the Hierarchy of Needs, emphasizing self-actualization after basic needs are met.

Carl Rogers (Humanist)

  • Pioneer of humanistic psychology; emphasized non-directive therapy centered on client involvement.

Client-Centered Therapy
  • Views clients as active participants in therapy, with therapists providing support rather than direction.

Viktor Frankl (Humanist)

  • Developed logotherapy, stressing the importance of finding meaning in suffering.

Jerry Fodor (Cognitivist)

  • Proposed the modularity of mind theory, emphasizing specialized processes in problem-solving.

Cognitive Psychology

  • Studies mental processes like reasoning, learning, and problem-solving.

  • Focuses on how stimuli are processed and how this affects behavior and emotions.

  • Investigates cognitive development, language acquisition, decision-making, and creativity.

Wilhelm Wundt (Structuralist)

  • Established the first experimental psychology lab and promoted introspective methods.

  • Developed Völkerpsychologie, examining collective behavior and the psychological history of humanity.

Gustav Fechner (Experimentalist)

  • Formulated Weber-Fechner Law, relating physical stimuli to associated sensations.

  • One of the founders of experimental psychology, demonstrating the mind's capacity for measurement and mathematical analysis.
