  • Goals of Science: Description, Prediction, Control
  • What science means by "theory"
  • Testability: Falsification (falsifying theory)
  • Approach to Research: hypothesis, research study design, collecting data, analyzing data & drawing conclusions, reporting findings
  • What is an experiment?
  • Types of variables
  • Types of groups in experiments
  • Problems faced in doing experiments
    • Non-random assignment
  • Advantages & disadvantages of experiments
  • Meaning of correlations: strong when approaching +/- 1.0; absent when approaching 0.0
  • Cause/effect vs. linkages
  • Descriptive/correlational research: purpose
  • Types of flaws in experimental research
  • Placebo effect
  • Types of distortions in self-report data
  • Ethics: Consent as voluntary, no harm, debriefing, right to privacy

Observational Learning/Social modeling
  • What is "learning" to a psychologist?
  • Classical conditioning as a theory of "signaling"
  • Pavlov's experiments with conditioning dogs to salivate
  • Watson's experiment with Little Albert: Fear conditioning
  • Examples of classical conditioning in everyday life, e.g., fears, phobias, political advertisements
  • Skinner's theory of "operant" conditioning
  • "Skinner Box" - components
  • Positive reinforcement: examples
  • Difference between negative reinforcement & punishment
  • Advantages of variable over fixed schedules of reinforcement
  • Learning "predispositions"
  • Garcia effect as "one shot learning"
  • Mental disorders as defined by their behaviors
  • Principle of positive reinforcement over punishment
  • What did Bandura discover about the effects of adult modeling on children in his Bobo Doll experiments?
  • What did researchers in the 1990s discover about the role of violence on television?
  • Why do some more recent researchers argue that there is much less of a link between media violence and real world violence than researchers used to claim?
