    Study Notes

    G.T. Fechner

    • Founder of Psychophysics: Fechner established psychophysics, a scientific method to quantify the relationship between physical stimuli and mental experiences.
    • Panpsychism: Believed in panpsychism, the idea that mind is present in everything.
    • Mind-Body Connection: Proposed psychophysical parallelism: a framework suggesting mental and physical events are intertwined but don't directly affect each other.
    • Inner and Outer Psychophysics: Distinguished between inner (brain and experience) and outer (external events and experience) psychophysics.
    • Mathematics and Human Experience: Believed in applying mathematics to human experience, arguing it defines boundaries within which individuals act.
    • Weber's Law and Sensory Measurement: Formulated Weber's Law: describes the relationship between stimulus magnitude and the change needed for noticeable difference in perception. Developed three methods to test this law empirically.
    • Quantity Objection: Critics argued sensations are not quantifiable, challenging the core of psychophysics.
    • Experimental Aesthetics: Contrasted traditional philosophical aesthetics with his empirical "aesthetics from below," emphasizing the observation of responses to art.

    Wilhelm Wundt

    • Founding Father of Experimental Psychology: Established the first experimental psychology laboratory in 1879, marking the formal beginning of psychology as a science.
    • Mental and Physical Events: Argued against a strict correspondence between mental and physical events, stating mental events have their own laws.
    • Cultural-Historical Psychology: Recognized the limitations of experimental methods for complex mental processes affected by culture.
    • Study of Cultural Artifacts: Focused on studying cultural products like language, myths, and social customs to understand the collective mind.
    • Language as a Cultural Product: Considered language as a reflection of cultural thought processes, incorporating the concept of apperception in his theory of language.
    • Rejection of Child Development: Argued against studying child development to understand thought development, as it's a culturally influenced, not a universal process.
    • Legacy: Faced criticism and reinterpretation. Renewed appreciation for his cultural psychology in modern times, recognizing its importance in highlighting social and historical factors on the human mind.

    Other Psychologists of the Time

    • Hermann Ebbinghaus: Pioneer in experimental studies of learning and memory using nonsense syllables to control prior knowledge. Developed the forgetting curve and proposed remote associations, suggesting connections between distant items in a list.
    • Mary Whiton Calkins: Invented the paired associates method, a technique still used today in learning and memory research.
    • Franz Brentano: Focused on mental acts (judging, sensing, loving) and their intentionality. Laid the foundation for phenomenological psychology.
    • The Würzburg School: Emphasized the use of systematic experimental introspection (retrospection) to study complex mental processes. Discovered imageless thoughts, challenging the assumption that all thought involves imagery. Introduced the concept of determining tendencies, unconscious mental sets guiding thinking based on tasks.

    Renaissance

    • Rebirth of Classical Ideas: Renewed interest in classical ideas and questioning of medieval thought.
    • Doubt and New Foundations: This questioning spirit led to doubt and a search for new foundations of knowledge.
    • Rene Descartes: Sought to establish a foundation for knowledge through rationalism, famously concluding "I think, therefore I am." Emphasized the mind's capacity for reason and believed in innate ideas originating from God.
    • Cartesian Dualism: Proposed a separation of mind and body, with the mind being immortal and the body a mechanical entity. Suggested the pineal gland as the point of interaction.

    The Influence of Darwin

    • Jean Baptiste Lamarck: Proposed the inheritance of acquired characteristics, later superseded by Darwin's theory.
    • Influence of Thomas Malthus: Malthus's work on population growth highlighted competition for resources, influencing Darwin's concept of natural selection.
    • Darwin's Theory of Evolution: Published in "On the Origin of Species," Darwin's theory centers on natural selection, or the survival of the fittest. This process leads to the evolution of new species.
    • Darwin vs. Lamarck: Unlike Lamarck's view, Darwin proposed that variations are random and beneficial traits are selected through survival and reproduction.
    • Alfred Russel Wallace: Independently developed a theory of evolution congruent with Darwin's, prompting their joint presentation at the Linnean Society.
    • Darwin's Impact on Psychology: Revolutionized biology and influenced psychology, leading to comparative psychology, the study of individual differences, and research on emotions, instincts, and child development.

    Central Questions in Psychology

    • Where does knowledge come from?
    • Is the mind separate from the body?

    Epistemology

    • Theory of Knowledge: Branch of philosophy exploring how we acquire knowledge. Addresses the source of knowledge.
    • Theories:
      • Nativism: Some knowledge is innate.
      • Empiricism: Knowledge is acquired through experience.
      • Rationalism: Reason is the source of knowledge, with an innate capacity to organize information from the senses.
      • Authority: Knowledge comes from perceived higher powers.

    Mind-Body Problem

    • Mind-Brain Separation: Addresses whether the mind is distinct from the brain.
    • Monism: One fundamental reality, mind and body are connected and the same.
      • Materialism: Everything is composed of matter. Mind is reduced to physical processes.
      • Idealism: Mental experience is the only reality.
    • Dualism: Two realities, mind and body are separate.
      • Interactionism: Mental and physical events are real and influence each other.
      • Psychophysical Parallelism: Mental and physical events are separate and influence only events of their own type.
