  2. 2. Lecture Overview• Introducing Psychology• Origins of Psychology• The Science of Psychology• Research Methods• Getting the Most from Your Study of Psycholog
  3. 3. Introducing Psychology• What is psychology? The scientific study of behavior & mental processes.• Psychology focuses on empirical evidence & critical thinking.• Pseudopsychologies (e.g., psychics, mediums) are nonscientific.
  4. 4. Pause & Reflect: Psychology & Life• Psychology helps us scientifically evaluate common beliefs & misconceptions about behavior & mental processes. For example, can you identify which of the beliefs on the following slide are true or false?
  5. 5. True or False?1. Most brain activity stops during sleep.2. Eyewitness testimony is often unreliable.3. People with schizophrenia have two or more distinct personalities.4. Similarity is one of the best predictors of long-term relationships.
  6. 6. Answers1. Most brain activity stops during sleep.  (False See Chapter 2)1. Eyewitness testimony is often unreliable.  (True See Chapter 7)1. People with schizophrenia have two or more distinct personalities.  (False See Chapter 13)1. Similarity is one of the best predictors of long-term relationships.  (True See Chapter 15)
  7. 7. Psychology’s Four Goals1. Description: tells “what” occurred2. Explanation: tells “why” a behavior or mental process occurred3. Prediction: identifies conditions under which a future behavior or mental process is likely to occur4. Change: applies psychological knowledge to prevent unwanted behavior or to bring about desired goals
  8. 8. Sample Careers in Psychology• Biopsychology/ • Experimental Neuroscience Psychology• Clinical & Counseling • Forensic Psychology Psychology • Gender/Cultural• Cognitive Psychology Psychology• Developmental • Health Psychology Psychology • Industrial/Organiza-• Educational tional Psychology Psychology • Social Psychology
  9. 9. Careers in Psychology: Percentageof Psychology Degrees by Specialty
  10. 10. Origins of Psychology• Wilhelm Wundt: “father of psychology”• Structuralism: sought to identify the basic building blocks, or structures, of mental life through introspection (Titchener key leader)• Functionalism: studied how the mind functions to adapt William James organisms to their environment (1842-1910) (James key leader)
  11. 11. Origins of Psychology: Continued• Psychoanalytic/ Psychodynamic Perspective: unconscious processes & unresolved past conflicts• Freud was key founder Sigmund Freud (1856-1939)
  12. 12. Origins of Psychology: Continued • Behavioral Perspective: objective, observable environmental influences on overt behavior • Watson & Skinner were key figuresB. F. Skinner (1904-1990)
  13. 13. Origins of Psychology: Continued• Humanistic Perspective: free will & self- actualization—led to modern field of positive psychology (Rogers & Maslow were key figures) + = Carl Rogers Abraham Maslow (1902-1987) (1908-1970)
  14. 14. Origins of Psychology: Continued • Cognitive Perspective: thoughts, perception, & information processing
  15. 15. Origins of Psychology: Continued • Neuroscientific/ Biopsychological Perspective: genetics & other biological processes in the brain & other parts of the nervous system
  16. 16. Origins of Psychology: Continued • Evolutionary Perspective: natural selection, adaptation, & evolution of behavior & mental processes • Sociocultural Perspective: social interaction & cultural determinants of behavior & mental processes
  17. 17. Origins of Psychology: Continued • Biopsychosocial model: combines biological, psychological, & social processes; interacts with the seven major perspectives
  18. 18. Pause & Reflect: Critical Thinking• Why do psychologists & other scientists need multiple perspectives? (One possible answer appears on the next slide.)
  19. 19. Do You See a Vase &/or Two Faces?• Multiple perspectives allow psychologists to better understand complex behavior & mental processes.
  20. 20. Origins of Psychology: Continued • Mary Calkins--one of the first women in psychology; first female president of APA • Margaret Floy Washburn--first woman to receive Ph.D. in psychology
  21. 21. Origins of Psychology: Continued• Francis Cecil Sumner--first African American Ph.D. in psychology• Kenneth B. Clark--first African American APA president; he & his wife (Mamie Clark) documented harmful effects of racial segregation in schools
  22. 22. The Science of Psychology• Basic Research: conducted to advance scientific knowledge• Applied Research: designed to solve practical problems
  23. 23. Pause & Reflect: Assessment• Is this an example of basic or applied research?
  24. 24. The Science of Psychology• Ethical Guidelines for Human Research Participants: • Informed consent • Voluntary participation • Restricted use of deception • Debriefing • Confidentiality • Alternative activities • Prior approval of research
  25. 25. The Science of Psychology• Rights of Nonhuman Participants: Psychologists take great care in handling research animals, & animal care committees ensure proper treatment. But the use of nonhuman animals for research remains controversial.• Rights of Psychotherapy Clients: Therapists must maintain highest of ethical standards & uphold clients’ trust & confidentiality.
  26. 26. Pause & Reflect: Assessment1. What are the four major goals of psychology?2. The _____ perspective focuses on natural selection, adaptation, & evolution.
  27. 27. Research Methods• Four key research methods: 1. Experimental 2. Descriptive 3. Correlational 4. Biological
  28. 28. Four Key Research Methods• Experimental Research: carefully controlled scientific procedure that manipulates variables to determine cause & effect
  29. 29. Research Methods: Experimental• Key features of an experiment: --Independent variable (IV) (factor that is manipulated) versus dependent variable (DV) (factor that is measured) --Experimental group (receives treatment) vs. control group (receives no treatment)
  30. 30. Research Methods: Experimental• Does TV increase aggression? Only an experiment can determine cause & effect.
  31. 31. Research Methods:Experimental (Continued)• Potential researcher problems: – Experimenter bias: researcher influences research results in his or her expected direction – Ethnocentrism: believing ones culture is typical of all cultures
  32. 32. Research Methods: Experimental (Continued)Potential participant problems:• Sample bias: research participants are unrepresentative of the larger population• Participant bias: research participants are influenced by the researcher or experimental conditions
  33. 33. Research Methods: Experimental (Continued)• One way to offset experimenter & participant bias is to create single- &/or double-blind experimental design.
  34. 34. Research Methods: Experimental (Cont.)
  35. 35. Research Methods: Descriptive2. Descriptive Research: observes & records behavior without producing causal explanations
  36. 36. Research Methods: Descriptive (Cont.) Three types of descriptive research: • Naturalistic Observation: researchers systematically measure & record participants’ behavior, without interfering • Survey: tests, questionnaires, polls, & interviews that assess a sample or population • Case Study: in-depth study of a single research participant
  37. 37. Why Study Psychology?(You discover topics like naturalistic observation, which also helps you “get” the underlying humor of popular cartoons.)
  38. 38. Research Methods: Correlational 3. Correlational Research: observes or measures (without directly manipulating) two or more variables to find relationships between them Art of Preiction
  39. 39. Correlational Research: (Continued)• Positive Correlation: two variables move (or vary) in the same direction—either up or down
  40. 40. Correlational Research: (Continued)• Negative Correlation: two variables move (or vary) in the opposite direction—either up or down
  41. 41. Research Methods: Correlational (Continued) • Zero Correlation: no relationship between two variables (when one variable increases, the other can increase, decrease, or stay the same)
  42. 42. Correlational Research: (Continued)
  43. 43. Correlational Research: (Continued) • Can you see why correlation can never show cause & effect?
  44. 44. Pause & Reflect: Assessment1. Why is an experiment the only way we can determine cause & effect?2. What is the difference between a positive correlation & a negative correlation?
  45. 45. Research Methods: Biological4. Biological Research: scientific studies of the brain & other parts of the nervous system
  46. 46. Tools for Biological Research
  47. 47. Tools for Biological Research (Cont.)
  48. 48. Getting the Most from Your Study of Psychology
  49. 49. Getting the Most from Your Study of Psychology (Continued)• Six major tools: – Familiarization – Active Reading (SQ4R) – Visual Learning – Time Management (baseline & realistic schedule) – Distributed Study – Overlearning
  50. 50. Pause & Reflect: Critical Thinking•Which of the tips offered in this section do youplan to work on to improve your academicperformance?
