An experimental design where the dependent variable is measured before and after the manipulation of the independent variable.
What is pretest-posttest design
100
A manipulation where one objective is to create some psychological state in the participants.
What is a stage manipulation?
100
Designs with more than one independent variable.
What are factorial designs?
100
A trial run of your study.
What is a pilot study?
200
An experimental design where the experimental and control conditions are studied with and without a pretest.
What is a Solomon four-group design?
200
These record responses of the body.
What are physiological measures?
200
This is necessary to see a curvilinear relationship between variables.
What are more than two levels of the independent variable?
200
A factorial design where participants are separated into different conditions on one independent variable and participate in all conditions of another independent variable.
What is a mixed factorial design?
300
This gives you more confidence that the randomization procedures worked.
What is a pretest measure?
300
Cues that inform the subject/participant how s/he is expected to behave.
What are demand characteristics?
300
You look at these if there is a significant interaction effect in order to determine where the interaction occurs.
What are simple main effects?
300
How many independent variables and levels (for each IV) are present in this factorial design?
2 x 4 x 6
Independent variables = 3
Levels = 2, 4, 6
400
This is when performance on the dependent variable declines with repeated measurement.
What is a fatigue effect?
400
A way to reduce experimenter AND participant expectancy effects.
What is double-blind experiment?
400
This is the number of main effects that are possible in a study examining the impact of gender, violence viewed, and violent peers on the rate of violent behavior.
What are 3 main effects?
400
If there are 20 participants in each condition, how many participants are needed in a 2 x 2 mixed factorial design?
40
500
When given the options between repeated measures and independent designs, this would be the best option when you are measuring your dependent variable with an extremely expensive machine.
What is a repeated measures design?
500
A measure that asks "Do you love this person?" that provides options of "yes" or "no" is less ________ than a 7-point Likert scale.
What is sensitive?
500
This is a reason to conduct a factorial design instead of two separate experiments.
What is finding an interaction between 2 or more independent variables?
500
Attrition can be better understood by measuring the participants at this time point.
What is pre manipulation of the independent variable (AKA use a pretest-posttest design)?
