Psych Mod-2

  1. Control Group
    the group not exposed to the treatment; contrasts with the experimental group, serves as a comparison, evaluating the effect of the treatment.
  2. Independent Variable
    Outcome factor thats MANIPULATED
  3. Dependent Variable
    • Out come factor that may CHANGE 
    • in response to manipulation of independent variable
  4. Survey
    technique for ascertaining self-reported attitudes or behaviors of particular group
  5. Naturalistic Observation
    • Naturally Occurring situations
    • without trying to manipulate or control the situation
  6. Case Study
    Observation technique, one person is studied in depth 
  7. Random Sampling vs Random Assignment
    • minimizes pre-existing differences 
    • vs
    • generalize from a small set of survey responses to a larger population
  8. Operational
    statement of the procedures (operations) used to define research variables
  9. Replication
    repeating research study with different participants
  10. Descriptive Method
    Observes and record behavior

    a self-correcting process for evaluating ideas with observation and analysis
  11. Data Gathering
    supports or fail theory of prediction
  12. Experimental Method
    Explores cause and effect
  13. Correlational Method
    Detects naturally occurring relationships

    how well one variable predicts another
  14. Blind Procedure
    Participant is (blind) uninformed about treatment
  15. Double Blind Procedure
    Participant and Researcher/Experimenter is blind about treatment

    who receives what drug or placebo
  16. Operational Theory
    explains principles that organize observations and predict behaviors or events
  17. Overconfidence Efect
    think we know more than we do

    more confident than correct
  18. Hindsight Bias
    I knew it all along

  19. Correlation
    • how two factors vary together 
    • how well either factor predicts the other
  20. Negative Correlation
    • 0 and -1.00 
    • inverse relationship
    • one thing increase the other decrease
  21. Positive Correlation
    • 0 and +1.00
    • direct relationship
    • two things increase or decrease together
  22. Experimental Group
    • group is exposed to treatment
    • to one version of independent variable
  23. Illusory Correlation
    • perceiving a relationship between variables  even when no such relationship exists.
    • (typically people, events, or behaviors)
