  1. Comparative Time Series Design (297)
    Quasi-experimental design, examines 2 or more variables over time to understand how changes in one variable are related to changes in another variable
  2. Contemporary History (293)
    In a quasi-experiment, a threat to the internal validity that develops when another event occurs at the same time as the quasi-IV
  3. Critical Multiplism (305)
    Philosophy that researchers should use many ways of obtaining evidence regarding a particular hypothesis rather than relying on a single approach
  4. Cross-sectional Design (299)
    A survey design in which a group of respondents is studied once
  5. Experimental Contamination (290)
    When participants in an experimental condition are indirectly affected by the IV in another condition because they interacted with participants in that condition
  6. Generational Effects (299)
    Differences among people of various ages that are due differences in generation rather than age
  7. Interrupted Time Series Design with a Reversal (295)
    A study in which (1) the DV is measured several times; (2) the IV is introduced; (3) the DV is measured more; (4) the IV is then withdrawn; (5) the DV is measured again several times
  8. Interrupted Time Series design with Multiple Replications (296)
    A study in which (1) the SV is measured several times; (2) the IV is introduced; (3) the DV is measured again; (4) the IV is withdrawn; (5) the DV in measured; (6) the IV is introduced a second time; (7) the DV is measured again; (8) the IV is withdrawn again; (9) the DV is measured after the IV has been withdrawn the second time
  9. Local History Effect (291)
    A threat to internal validity in which an extraneous event happens to one experimental group that doesn't happen to the other group
  10. Longitudinal Design (299)
    A study in which a single group is studied over time
  11. Nonequivalent Control Group Design (289)
    A quasi-experimental design, a group of participants receive the quasi-IV & is compared to one or more groups of participants who don't
  12. Nonequivalent Groups Pretest-posttest Design (287)
    A quasi-experimental design, two preexisting groups are tested-one that has received the IV & one that hasn't, the groups are tested twice-once before & once after one group received the IV
  13. Preexperimental Design (288)
    A design that lacks the controls to minimize threats to internal validity; typically don't have adequate control or comparison groups
  14. Program Evaluation (301)
    The use of behavioral research methods to assess the effects of programs on behavior, also called evaluation research
  15. Quasi-experimental Design (286)
    Research design where the researcher can't assign participants to conditions and/or manipulate the IV; Instead, comparisons are made between existing groups or with a single group before and after a quasi-experimental treatment has occurred
  16. Quasi-independent Variable (286)
    The IV in a quasi-experimental design; quasi-independent is used when the variable isn't manipulated
  17. Regression to the Mean (288)
    The tendency for participants with extreme scores on some measure to obtain less extreme scores when retested
  18. Selection Bias (289)
    A threat to internal validity that arises when the experimental groups weren't equivalent before the manipulation of the IV or quasi-IV
  19. Selection-by-history Interaction (291)
    A threat to internal validity in which an extraneous event happens to one experimental group that doesn't happen to the other group, AKA local history effect
  20. Simple Interrupted Time Series Design (293)
    A quasi-experimental design in which participants are tested on many occasions-several before and after the occurrence of the quasi-IV
  21. Time Series Design (293)
    A class of quasi-experimental designs in which participants are tested on many occasions-several before & after the occurrence of a quasi-IV
