Factorial Design
Show Answers:

  1. ___ experiments study the effects of two or more independent variables in a single experiment
  2. ___ are researchers who pretend to be real participants.
  3. A ___ ___ ___ is the effect of one independent variable at a specific level of a second independent variable.
    simple main effect
  4. The average of a treatment's two simple main effects gives us the ___ main effect.
  5. An ___ ___ ___ is the average effect of an independent variable.
    Overall Main Effect
  6. An ___ ___ is how much of one variable participants must receive to have an effect on another variable.
    Interaction Effect
  7. When simple main effects of one variable differ, depending on the level of another variable, there is a(n) ___ effect.
  8. Because the ___ effects of many variables are already known, psychology looks at ___.
    Main / Interactions
  9. A ___ ___ design uses matching to reduce the effects of ___ variables.
    Matched-Pairs / Extraneous
  10. Matched-Pairs designs use ___ ___ to establish internal validity.
    random assignment
  11. In a ___ ___ design, ___ participant recieves ___ levels of the treatment. 
    within-subjects / every / all
  12. In a within-subjects design, every participant is measured ___ receiving ___ level of the treatment.
    after / each
  13. ___ designs are used so that we don't have to choose between a completely within-subjects or between-subjects design.
  14. In a mixed design, there is at least one ___-subjects factor and at least one ___-subjects factor.
    within / between
  15. W/I subjuscts design

    ___ effects may influence results depending on which treatment comes first or last.
  16. W/I subjects design

    ___ effects occur when paricipants have learned from the first task (before taking the posttest)
  17. W/I subjects design

    ___ effects occur when participants do worse on later trials due to becoming bored or tired.
  18. W/I subjects design

    ___ effects occur when the effects of an earlier treatment influence responses on later trials
  19. To minimize ___ effects, do not administer treatments in the same sequence to all participants
  20. To minimize ___ effects, give participants lots of practice before the experiment begins.
  21. To minimize ___ effects, make the experiment interesting, short and easy to complete.
  22. To minimize ___ effects, increase the time between treatments - have participants come back a second day.
  23. counterbalaced within-subjects design will minimize (balance out) ___ effects.

    Each participant gets more than one treatment (in a different sequence)

    - A/B for some participants
    -B/A for other participants

    The only disadvantage is that it requires ___ ___.
    order / more participants
  24. The randomized matche-pairs experiment randomly assigns ___ ___ ___ to different treatment sequences.
    members of pairs
  25. The randomized within-subjects experiment randomly assigns ___ ___ to different sequences of treatments
    individual participants
  26. ___ is the position in a sequence:

    - 1st, 2nd, 3rd, ....
  27. ___ effects is when participants score differently depending on their sequence of treatments. 
  28. Between-Subjects Factorial design:

    Worried about: ___

    Not worried about: ___
    order effects / not power
  29. Within-Subjects Factorial Design:

    Worried about: ___

    No problems with: ___
    worried about Power

    not worried about carryover, practice, fatigue, or order effects
  30. Treatment changes correlate with behavioral changes
  31. Treatment preceded behavioral changes
    Temporal Precedence
  32. Single-n designs use the term ___ to refer to results that are due to other variables.

    cause/ effect
  33. In order to handle uncontrolled variables, we convert ___-___ variables into ___ variables.
    non-treatment/ random
  34. A  ___ is a "record" of consistent behavior recorded prior to administering treatment.
  35. In the A-B design, a ___ ___ is studied
    single participant
  36. A-B design

    - The ___ behavior is called A

    - The ___ is administered

    - The ___-___ behavior is called B

    - ___ treatment

    - Measures ___ (A)
    baseline/ administers/ post-treatment/ withdraws/ behavior
  38. In the ___ design, participants are required to judge stimuli
  39. In the ___-___ design, baselines are collected for several key behaviors

    *one behavior is ___ and ___*

    reinforces / measured
  40. In the ___-___, a treatment is administered but participants are not randomly assigned to conditions.

    - Because real life does not reflect ___ ___!
