  12. The birth of modern psychology: A brief history

  13. Roots of Psychology: • Philosophy • Natural sciences

  14. Natural Sciences • Charles Darwin • Natural selection: Organisms best adapted to their world are most likely to survive, reproduce, and pass on characteristics to their offspring [see evolutionary psychology, p8]

  15. Philosophy • William James • Functionalism Early approach that emphasized the function or purpose of behavior and consciousness[p7]

  16. Psychology • Wilhelm Wundt • 1st psych laboratory • Trained introspection: A process by which individuals were taught to carefully observe, analyze, and describe their own sensations, mental images, and emotional reactions [p7]

  17. Psychology • Sigmund Freud • Psychoanalysis: A theory of personality and a method of psychotherapy, originally formulated by Sigmund Freud • Emphasizes unconscious motives and conflicts[p7]

  18. Five current perspectives in psychology

  19. Major psychological perspectives • Biological perspective • Learning perspective • Cognitive perspective • Sociocultural perspective • Psychodynamic perspective

  20. The biological perspective Psychological approach that focuses on how bodily events affect behavior, feelings, and thoughts [p8] This perspective involves Hormones Brain chemistry Heredity Evolutionary influences

  21. The learning perspective Emphasizes how the environment and experiences affect the behavior of any organism [p8] This perspective involves Behaviorism Social cognitive learning theory

  22. The cognitive perspective Psychological approach that emphasizes what goes on in people’s heads [pp8-9] This perspective involves Problem solving Perception Attention Remembering Thinking

  23. The sociocultural perspective Psychological approach that emphasizes social and cultural forces outside the individual [p9] This perspective involves Social psychology or the study of rules, roles, groups, and relationships Cultural psychology or the study of culturalnorms, values, and expectations

  24. chapter 1 The psychodynamic perspective Psychological approach that emphasizes unconscious dynamics within the individual, such as inner forces, conflicts, or the movement of instinctual energy [p9] This perspective involves Unconscious thoughts, desires, conflicts

  25. Eclectic psychology Psychological approach that selects the best features of each approach, depending on the problem at hand.

  26. What psychologists do[pp10-13]

  27. chapter 1 Research and teaching Examples: Experimental psychologists Educational psychologists Developmental psychologists Industrial/organizational psychologists Psychometric psychologists

  28. chapter 1 Health and mental health services Counseling psychologists help people deal with problems associated with everyday life. School psychologists work with parents, teachers, and students to enhance student performance. Clinical psychologists diagnose, treat, and study mental or emotional problems.

  29. Psychologists in other settings Sports Consumer issues Advertising Organizational problems Environmental issues Public policy Opinion polls Military training Animal behavior Legal issues

  30. Careers in psychology:

  31. Critical and scientific thinking

  32. Critical thinking guidelines Ask questions Define your terms Examine the evidence Analyze assumptions and biases Avoid emotional reasoning Don’t oversimplify Consider other interpretations Tolerate uncertainty

  33.  Ask questions; be willing to wonder • Theory: an organized system of assumptions and principles that tries to explain a certain set of phenomena and their interrelationships [p18] • Example: “Boys are rougher than girls”

  34.  Define your terms • Hypothesis: a statement that attempts to predict or account for a set of phenomena. [p15] • Example: “Toys that are played with by boys will show more signs of wear than toys that are played with by girls” • Operational definition:a precise definition of a term in a hypothesis[p15]

  35.  Examine the evidence

  36.  Analyze assumptions and biases • Assumption: belief that is taken for granted [p16] • Bias: assumption that keeps us from considering the evidence fairly [p16]

  37.  Avoid emotional reasoning

  38.  Avoid oversimplifying • Argument by anecdote: generalize from a personal experience or from a few examples to everyone [p17]

  39. Consider other interpretations  Tolerate uncertainty

  40. Collecting data: Research methods

  41. Researchers carefully and systematically observe and record behavior without interfering with behavior Naturalistic observation Purpose is to observe how people or animals behave in their natural environments. Laboratory observation Purpose is to observe how people or animals behave in a more controlled setting. Observational studies [p21]

  42. chapter 1 Descriptive methods Methods that yield descriptions of behavior, but not necessarily causal explanations [p20] Include Observational studies Case studies Psychological tests Surveys

  43. Case studies A detailed description of a particular individual being studied or treated, which may be used to formulate broader research hypotheses [p20] Most commonly used by clinicians; occasionally used by researchers

  44. Surveys Questionnaires and interviews that ask people about experiences, attitudes, or opinions [p23] Social desirability: the tendency of participants to respond in a way they think is socially acceptable or desirable rather than how they truly feel or think

  45. Psychological tests Procedures used to measure and evaluate personality traits, emotional states, aptitudes, interests, abilities, and values [p22]

  46. Standardization The test is constructed to include uniform procedures for giving and scoring the test. In order to score tests in a standardized way, an individual’s outcome or score is compared to norms. [p22]

  47. Correlational study A descriptive study that looks for a consistent relationship between two phenomena [p24] Correlation A statistical measure of how strongly two variables are related to one another. [p24] Correlational coefficients can range from -1.0 to +1.0.

  48. Direction of correlations [pp24-25] Positive correlations An association between increases in one variable and increases in another, or decreases in one variable and decreases in the other. Negative correlations An association between increases in one variable and decreases in another.

  49. Correlations show patterns, not causes. Explaining correlations

  50. Experimental research  Allows psychologists to determine the cause of a behavior [p26]
