Foundations of Psychology, Part I — Comprehensive Notes

Foundations of Psychology, Part I

  • Psychology as a science

    • Psychologists systematically seek answers to how and why we think, feel, and act as we do.
    • Scientific inquiry involves testing competing ideas to see which fit the facts best.
    • Emphasizes avoiding misleading conclusions and avoiding being misled.

  • Steps of the Scientific Method

    • Make an observation
    • Ask a question
    • Test hypothesis and gather data
    • Examine test results and form a conclusion
    • Report findings
    • These steps are often cyclical; conclusions can lead to new questions and observations.

  • How is psychology a science?

    • Employs systematic methods of inquiry to study behavior and mental processes:
    • Empirical evidence
    • The Scientific Method
    • Theoretical frameworks
    • Quantitative and qualitative research
    • Objectivity and control
    • Peer review and replication

  • Thinking critically about the scientific attitude

    • Three basic attitudes have helped science progress:
    • Curiosity: Does it work? Can predictions be confirmed when tested?
    • Skepticism: What do you mean? How do you know? Distinguish reality from fantasy; avoid gullibility.
    • Humility: Be willing to be surprised and follow new ideas; predictions about people/animals may be wrong.
    • Example questions explored in class:
    • Can some people read minds?
    • Do facial expressions and body postures affect how we feel?
    • Are stress levels related to health and well-being?
    • Do parental behaviors determine children’s sexual orientation? (Module 34 notes indicate no relationship.)
    • The phrase "The rat is always right" captures a commitment to empirical results over biased belief.

  • Critical thinking

    • Thinking that does not automatically accept arguments and conclusions.
    • Critical thinking, informed by science, helps check biases.
    • Critical thinkers recognize multiple perspectives.

  • Philosophical roots (Plato and Aristotle)

    • Plato (before 300 B.C.E.)
    • Believed in innate ideas; brain as the seat of mental processes.
    • Aristotle (before 300 B.C.E.)
    • Denied innate ideas; theorized about learning, memory, motivation and emotion, perception, and personality.

  • Psychology’s first laboratory

    • Wilhelm Wundt and two graduate students
    • December 1879: University of Leipzig, Germany
    • The experiment compared:
    • Press the key as soon as you hear a ball hit a platform: about rac110rac{1}{10} of a second
    • Press the key as soon as you are consciously aware of perceiving the sound: about rac210rac{2}{10} of a second
    • Called the mind’s fastest and simplest mental processes "atoms of the mind."

  • Structuralism (1890s)

    • Edward Bradford Titchener
    • Focused on elements of the mind’s structure
    • Used self-reflective introspection to report elements of experience
    • Results were varied and the method was unreliable

  • Functionalism (1870s)

    • William James
    • Emphasized the functions of our inner thoughts and feelings
    • Early US psychology courses at Harvard (began in 1875)
    • Studied emotions, memories, willpower, habits, and stream of consciousness thinking

  • Psychology’s first women

    • Mary Whiton Calkins
    • 1890: Joined William James at Harvard; studied memory
    • Completed all PhD requirements but was denied the degree
    • 1905: First female president of the American Psychological Association (APA)
    • Margaret Floy Washburn
    • Mentored by Titchener
    • First woman to officially earn a Ph.D. in Psychology
    • Authored The Animal Mind
    • 1921: Second female president of the APA

  • Nature–Nurture issue

    • BCE era concepts:
    • Plato: innate character and intelligence; some ideas are innate
    • Aristotle: there is nothing in the mind that does not first come in from the external world through the senses
    • 1600s: John Locke — the mind is a blank slate on which experience writes
    • René Descartes — some ideas innate

  • Behaviorism (1920s)

    • Core idea: Psychology should be an objective science that studies behavior without reference to mental processes
    • Key figures: John B. Watson and Rosalie Rayner
    • Emphasized observable behavior; unobservable mental processes were not the subject of science
    • Notable study: "Little Albert" and learned fear

  • The Little Albert experiment

    • Classic demonstration in behaviorism illustrating conditioned fear responses

  • Behaviorism, continued

    • B. F. Skinner
    • Redefined psychology as “the scientific study of observable behavior”
    • Rejected introspection
    • Studied how consequences shape behavior
    • Behaviorism remained influential into the 1960s

  • Psychoanalytic approach (early 1900s)

    • Sigmund Freud
    • Emphasized how the unconscious mind and childhood experiences influence behavior
    • Viewed as a personality theory with focus on:
    • Unconscious conflicts, including sexual conflicts
    • Mind’s defenses against its own wishes and impulses

  • Humanistic psychology (1960s)

    • Critics of behaviorism’s narrow focus
    • Carl Rogers and Abraham Maslow
    • Emphasized human growth potential and need for love and acceptance
    • Focus on environments that nurture or limit personal growth

  • Early schools of psychology

    • Major schools discussed in foundations section:
    • Structuralism
    • Functionalism
    • Behaviorism
    • Psychoanalytic approach
    • Humanistic psychology
    • These sections are summarized together as foundational or early schools of thought in psychology

  • Looking ahead

    • Next class: Foundations of Psychology, Part II (Chapter 1)
    • Preview: building on Part I concepts and exploring new approaches and findings

  • Quick reference to figures and themes mentioned

    • Wilhelm Wundt — first psychology laboratory (1879)
    • Edward Bradford Titchener — structuralism
    • William James — functionalism; Harvard course creator
    • Mary Whiton Calkins — memory researcher; APA president
    • Margaret Floy Washburn — first official Ph.D. in Psychology; APA president
    • Sigmund Freud — psychoanalytic theory; unconscious mind
    • Carl Rogers and Abraham Maslow — humanistic psychology
    • John B. Watson and Rosalie Rayner — early behaviorists
    • B. F. Skinner — operant conditioning and observable behavior

  • Notable quotes and phrases to remember

    • "Atoms of the mind" — fastest and simplest mental processes
    • "The rat is always right" — emphasis on empirical verification over assumptions

  • Important dates and milestones

    • 1879 — Wundt’s laboratory (founding moment of psychology as a science)
    • 1890s — Structuralism prominence
    • 1875 — James begins one of the first psychology courses in the US at Harvard
    • 1905 — Calkins becomes APA president (female leadership)
    • 1921 — Washburn becomes APA president

  • Connections to broader themes

    • Psychology as a science builds on empirical evidence, theory, and replication
    • Early schools laid groundwork for understanding behavior, mental processes, and human motivation
    • Debates on nature vs. nurture, mind vs. behavior, and the role of the unconscious shaped later research directions

  • Practical and ethical implications (implicit in notes)

    • Emphasis on replication and peer review highlights the importance of reliability and validity in findings
    • Historical methods (e.g., introspection) show why modern methods favor observable, measurable data
    • Understanding the historical roots helps in evaluating modern psychology practices and claims
