  1. Chapter 1: The Evolution of Psychology

  2. Psychology • Derived from two Greek words: • Psyche meaning soul • And logos meaning the study of a subject

  3. From Speculation to Science:How Psychology Developed • Prior to 1879 • Physiology and philosophy scholars studying questions about the mind • Wilhelm Wundt (1832-1920) University of Leipzig, Germany • Campaigned to make psychology an independent discipline • Established the first laboratory for the study of psychology in 1879 • Psychology was born= 1879 • Modeled after science fields like physics and chemistry

  4. Wilhelm Wundt’s International Influence • Leipzig, the place to study psychology • Graduates of Wundt’s program set up new labs across Europe and North America • Wundt generated over 54,000 pages • G. Stanley Hall (1846-1924), Johns Hopkins University • Established the first psychology laboratory in the U.S. in 1883, established the APA • Between 1883 and 1893, 23 new laboratories in North America

  7. The Battle of the “Schools” in the U.S.: Structuralism vs. Functionalism • Structuralism – Edward Titchener • Analyze consciousness into basic elements and investigate how these elements were related • They wanted identify and examine things like: sensations, feelings, and images (visions, hearing, and touch) they used: • Introspection – careful, systematic observations of one’s own conscious experience

  8. The Battle of the “Schools” in the U.S.: Structuralism vs. Functionalism • Functionalism – William James (1842-1910) • Wrote, Principles of Psychology (most influential psyc text in History) • Influenced by Darwin’s natural selection • Wanted to investigate the flow of thoughts (stream of consciousness) • More concerned about how people adapt their behavior to the demands of the real world around them • Investigate function (or purpose) of consciousness • Led to investigation of mental testing, developmental patterns, and sex differences

  9. The Battle of the “Schools” in the U.S.: Structuralism vs. Functionalism • The fight was over the future direction of Psychology • Most historians believe that functionalism won the fight • Partly due to the fact that it fathered behaviorism and applied psychology • Natural Selection: inheritable characteristics that provide a survival or reproductive advantage are more likely than alternative characteristics to be passed on, and such become selected

  10. Sigmund Freud and the Concept of the Unconscious Mind • Sigmund Freud(1856-1939): Austria • His approach to psyc. grew from his attempt to treat mental disorders • Founded Psychoanalytic school of thought • Emphasis on unconscious processes influencing behavior • Unconscious = outside awareness • Dreams, Freudian Slips, Sex • Suggested that people might not be the masters of their own minds

  11. Freud’s Ideas:Controversy and Influence • Behavior is influenced by the unconscious • Unconscious conflict related to sexuality plays a central role in behavior • Controversial notions caused debate/resistance • Significant influence on the field of psychology

  12. Behaviorism: Redefining Psychology • John B. Watson (1878-1958): United States • Founder of Behaviorism which stated the Psyc. Should only study observable behaviors • Psychology = scientific study of behavior • Behavior = overt or observable responses or activities • Radical reorientation of psychology as a science of observable behavior • Study of consciousness abandoned

  13. John Watson and the Nature-Nurture Debate • Nurture, not nature • “give me a dozen healthy infants, well-formed, and my own special world to bring them up in and I’ll guarantee to take any one at random and train him to become any type of specialist I might select – doctor, lawyer, artist, merchant-chief, and yes, even beggar-man and thief…” • Behaviorist school of thought emphasized the environment (nurture) • Focus on stimulus-response relationships • S-R psychology (Pavlov) • Gave rise to animal research

  14. Are people free?B.F. Skinner • B.F. Skinner (1904-1990): United States • One of the most influential American psychologists championed a return to the strict focus on OBSERVABLE behavior only • Environmental factors determine behavior • Responses that lead to positive outcomes are repeated • Responses that lead to negative outcomes are not repeated • Beyond Freedom and Dignity: all behavior is influenced by external stimuli or people are controlled by their environments • More controversy regarding free will

  15. The 1950’s: Opposition to Psychoanalytic Theory and Behaviorism • Charges that both were de-humanizing (psychoanalysis dominated by sexual urges, behaviorism was dominated by simple animal behaviors) • Diverse opposition groups got together to form a loose alliance • A new school of thought emerged - Humanism • Led by Abraham Maslow (1908-1970) and Carl Rogers (1902-1987) • More optimistic view of human nature • Emphasis on the unique qualities of humans: freedom and personal growth, people are fundamentally different than animals

  16. Psychology Comes of Age as a Profession • Applied Psychology: concerned with everyday practical problems • Clinical Psychology: concerned with the diagnosis and treatment of psychological problems and disorders • Advanced by WW II and the need to treat mental disorders of those returning from the war

  17. Putting the Psyche Back in Psychology:The Return of Cognition • Cognition = mental processes involved in acquiring knowledge- thinking or conscious experience • 1950’s and 60’s – • Piaget- focused on children's development • Chomsky- focused on the psyc of language • Simon- focused on mental problem solving • Application of scientific methods to studying internal mental events • Cognitive psychology: the new dominant perspective?

  18. Biological Psychology:The Biological Basis of Behavior • Biological perspective - behavior explained in terms of physiological processes • James Olds (1956) • Electrical stimulation of the brain evokes emotional responses (such as pleasure and rage) in animals • Roger Sperry (1981) • Left and right brain specialization

  19. Cultural Psychology:Recognizing Human Variation • Ethnocentrism – viewing one’s own group as superior and as the standard for judging • Historically: middle and upper class white males studying middle and upper class white males • 1980’s – increased interest in how cultural factors influence behavior • Growing global interdependence • Increased cultural diversity

  20. Evolutionary Psychology:Human Adaptations • Central premise: natural selection occurs for behavioral, as well as physical, characteristics • Buss, Daly & Wilson, Cosmides & Tooby – 80’s and 90’s • Studied natural selection of mating preferences, jealousy, aggression, sexual behavior, language, decision making, personality, and development • Thought provoking perspective gaining in influence, but not without criticism

  21. Figure 1.5 Increased cultural diversity in the United States

  22. Positive Psychology • Martin Seligman’s epiphany • Humanist concerns revisited • Uses theory and research to better understand the positive, creative, and fulfilling aspects of human existence • Positive subjective experiences: happiness, love, gratitude, contentment, and hope • Positive individual traits: courage, perseverance, tolerances, creativity • Positive institutions and communities: strong families, healthy work environments

  23. Table 1.1 Overview of Six Contemporary Theoretical Perspectives in Psychology

  24. Psychology Today:A Thriving Science and Profession • Psychology is the science that studies behavior and the physiological and cognitive processes that underlie it, and it is the profession that applies the accumulated knowledge of this science to practical problems. • Research: Seven major areas • Applied Psychology: Four major areas

  28. Studying Psychology:Seven Organizing Themes • Psychology as a field of study: • Empirical: Knowledge should be acquired through observation • Theoretically diverse: we have already looked at 6 • Evolves in sociohistorical context: it is ever evolving • Behavior: • Determined by multiple causes • Shaped by cultural heritage • Influenced jointly by heredity and environment • People’s experience of the world is highly subjective.
