"When I Heard The Learn'dAstronomer (Walt
Whitman)

• When I heard the learn'd astronomer,
• When the proofs, the figures, were ranged in
  columns before me,
• When I was shown the charts and diagrams, to
  add, divide, and measure them,
• When I sitting heard the astronomer where he
  lectured
• With much applause in the lecture-room,

12
Whitman, continued...

• How soon unaccountable I became tired and sick,
• Till rising and gliding out I wander'd off by
  myself,
• In the mystical moist night-air, and from time to
  time,
• Look'd up in perfect silence at the stars.

13
The scientific method

• 1. Hypothesis formation
• Specify the research question or problem
• Study the research literature
• Formulate a hypothesis as a possible answer
• 2. Design the research
• Generate predictions
• Select a method

14
Scientific method...

• 3. Conduct the study, collect the data
• 4. Analyze the data to assess the predictions
• 5. Explain what the assessment of the predictions
  says about the truth of the hypothesis.
  Communicate your study to the scientific
  community.

15
Descriptive research

• The case study
• Depth over breadth
• Risk of overgeneralization
• May disprove a hypothesis
• The survey
• Effects of wording and method
• Sampling can overcome false consensus
• Naturalistic observation

16
Research methods in psychology

• Research strategies
• Description
• Correlation
• Experimentation

17
Correlation

• What does correlation mean?
• Illusory correlation
• Confirmation bias
• Spurious correlations
• Correlation and causation

18
Research methods in psychology

• Research strategies
• Description
• Correlation
• Experimentation

19
Experimentation

• Random selection for representative sample
• Random assignment for equivalent groups
• Control or comparison condition
• Manipulation of independent variable
• Measurement of dependent variable

20
Making explanations

• The nominal fallacy and circular explanation
• Operational definition of variables
• Independent variable How is it manipulated?
• Dependent variable How is it measured?
• Validity of operational definitions
• Reliability of measurements
• Interrater reliability

21
Confounding variables Reaction time to shapes
How could we use counterbalancing to remove the
confounding in this study?
22
Two experiments

• Hypothesis one Speaking out in class will kill
  you.
• Hypothesis two Men have faster reaction times
  than women.
