Slide # 14 Early Researchers
Slide # 15 Wilhelm Wundt (1832–1920) He used introspection as a research technique Wundt’s lab
Slide # 16 Edward Titchener (1867–1927) Structuralism (an early school of psychology) The mind is structured by breaking down mental experiences into their components G. Stanley Hall, American Psychological Association
Slide # 17 William James and Functionalism The school of psychology that focuses on the adaptive functions of behavior The study of why we do what we do The influence of Darwin
Slide # 18 John Watson Behaviorism—the study of overt behavior He rejected introspection Psychology should become a science of behavior Environment molds the behavior of us all
Slide # 19 B.F. Skinner ( ) Behaviorism gets a boost from Skinner Behavior is shaped by rewards and punishment
Slide # 20 Gestalt Psychology Max Wertheimer Gestalt studies the ways in which the brain organizes and structures our perceptions The whole is greater than the sum of its parts
Slide # 21 Sigmund Freud The unconscious mind We do and say things without understanding our motives
Slide # 22 The Empirical Approach A method of developing knowledge based on gathering evidence, performing experiments, or careful observation Psychologists need to distinguish between inference and observation
Slide # 23 The Scientific Method A framework for acquiring knowledge through observation and experimentation (4 steps) — Come up with a question — Develop a hypothesis — Gather evidence — Draw conclusions
Slide # 24 Research Questions Sources used: observation, previous experiences, beliefs Questions eventually become hypotheses
Slide # 25 The Hypothesis A precise prediction about the outcome of an experiment Example: Is there a relationship between reckless driving and gender? Dependent vs. independent variables
Slide # 26 Gathering Evidence Develop a research design or strategy to provide a scientific test of the hypothesis The type of research used depends on what a researcher wants to try to measure
Slide # 27 Drawing Conclusions About The Hypothesis Conclusions about the hypothesis are based on the evidence collected Statistics Replication
Slide # 28 Selecting a Sample Random sampling The sample needs to be representative Generalize or transfer
Slide # 29 Stratified Samples Selecting individuals from a larger group based on age, sex, ethnicity, etc.
Slide # 30 Research Methods The case study method The survey method The naturalistic observation method The experimental method The longitudinal method The cross sectional method
Slide # 31 The Case Study Method An in-depth study of one or more individuals Information collected from interviews, observation, written records, artwork The work of Jean Piaget
Slide # 32 The Artwork of Mental Patients Using artwork as a research tool
Slide # 33 Jose de Goya: Self Portrait
Slide # 34 The Stabbing

Slide # 42 Lonnie
Slide # 43
Slide # 44 Vincent Van Gogh
Slide # 45 Review If you were a psychologist, what general observations could you make about the artwork of mental patients? How are colors important in the psychology of art? Remembering the drawings made by Joanne. Explain how her progression of self- portraits reflects her psychological improvement.
Slide # 46 The Survey Method Uses structured interviews or questionnaires to gather information about groups of people Disadvantages
Slide # 47 Common Uses of and Concerns about the Survey Method Anonymity: Subjects may open up more than in other situations Studies about mental health or consumer satisfaction Social desirability bias and volunteer bias
Slide # 48 Naturalistic Observation Method Based on careful observation of behavior in natural settings without interfering What researchers have learned using this technique Problems
Slide # 49 Longitudinal Studies The same person or group of persons are studied at regular intervals over a period of time Used to determine whether people’s behavior/feelings have changed An example
Slide # 50 Cross-Sectional Studies Data is collected from groups of participants of different ages Data is compared, conclusions are drawn Advantages, disadvantages
Slide # 51 Correlations and Explanations Correlations: the measure of a relationship between two variables or sets of data Positive correlations between high IQ and good grades
Slide # 52 Correlations vs. Cause and Effect A correlation describes a relationship between two things; it does not mean that one causes the other There may be a third factor involved with positive correlations
Slide # 53 Correlation Types Correlation coefficient: a statistical measure of association between variables; it can vary from to +1.00
Slide # 54 Benefits of a Correlational Method It offers clues to underlying causes of behavior It can identify people at risk for physical or behavioral problems It can increase understanding of relationships between variables or events
Slide # 55 The Experimental Method
Slide # 56 The Experimental Method Independent variables: factors manipulated in an experiment Dependent variables: the effects or outcomes of an experiment that are believed to be dependent on the values of the independent variables
Slide # 57 Application Look at the following photographs and decide which subjects you consider most attractive
Slide # 58 Gertrude
Slide # 59 Kristen
Slide # 60 Ethel
Slide # 61 Christine
Slide # 62 Maude
Slide # 63 Prudence
Slide # 64 Matilda
Slide # 65 Sheri
Slide # 66 Megan
Slide # 67 Gladys
Slide # 68 Evaluation Does the popularity of a woman’s name affect judgment of their physical attractiveness? The independent variable: type of name The dependent variable: ratings of attractiveness
Slide # 69 Control Groups Groups of participants in a research experiment who do not receive the experimental treatment or intervention Placebo effects
Slide # 70 Single-Blind Experiments Keeping subjects uninformed
Slide # 71 Double-blind Both the subject and the experimenter are kept uninformed
Slide # 72 Ethics In Research Stanley Schachter’s 1959 study on anxiety and affiliation
Slide # 73 Ethics in Research (cont.) How would you have felt if you were one of the subjects in the high-anxiety group? Should researchers be allowed to misrepresent their research?
Slide # 74 Deception Deception has been fairly common in psychological research since the 1960s, especially in the area of social psychology Deception is used to reduce problems associated with the placebo effect
Slide # 75 Animal Research Do the laws of behavior apply to both humans and animals? Animals are sometimes exposed to treatments that would be “unthinkable” to perform on humans
Slide # 76 Guidelines for Ethical Research Participation is voluntary No exposure to harmful procedures If deception is used, a full explanation should follow the session Privacy should not be violated Harmful procedures imposed on animals must not be allowed Approval from host institutions is necessary
