QuestionAnswer
Threats to Validity Problems that could cause an experiment to be invalid
History Although scores for the treatment group change between the pretest (before treatment) and the post-test (after treatment) it is not clear that this change is the result of the treatment.
History continued It may, instead, be the result of some other event that took place during the intervening time.
Maturation Although scores for the treatment group change between the pretest (before treatment) and the posttest (after treatment) it is not clear that this change is the result of the treatment
Maturation continued It may, instead, be the result of some normal development that occurred during the intervening time.
Testing Although scores for the treatment group change between the pretest (before treatment) and the posttest (after treatment) it is not clear that this change is the result of the treatment. It may, instead, be the result of repeated testing.
Experimental Mortality Although scores for the treatment group change between the pretest (before treatment) and the posttest (after treatment) it is not clear that this change is the result of the treatment.
Experimental Mortality continued It may, instead, be the result of many people dropping out of the experiment before it was finished.
Statistical Regression Although scores for the treatment group change between the pretest (before treatment) and the posttest (after treatment) it is not clear that this change is the result of the treatment.
Statistical Regression continued It may, instead, be the result of the fact that people who get unusually high or low on any test are likely to have more average scores when they are tested again.
Experimenter Expectancy Although scores for the treatment group change more than scores for the control group between the pretest (before treatment) and the posttest (after treatment) it is not clear that this change is the result of the treatment.
Experimenter Expectancy continued It may, instead, be the result of the experimenter sub-consciously favoring one group more than the other.
Possible multiple choice questions about experiments Possible multiple choice questions about experiments
Why do we do experiments rather than questionnaires? What people think is not necessarily what they do.Hard to distinguish cause and effect. Does confidence lead to success or the reverse? Hard to tease apart multiple factors
Why do we do experiments rather than observation studies; rather than Interviews? Cannot explain why people act as theyObservation studies describe complex behavior – hard to isolate essential ingredients
What are some of the limitations to doing experiments? Difficult to simulate some complex, real-world situations. Sometimes difficult to assign subjects randomly. Difficult to handle large numbers of subjects only large effects are visible.Difficult to focus on more than a few variables
What are some of the limitations to doing experiments? Usually focus on 1-2 variables Unlike surveys which can address multiple variables in relation to each other
Why might it be important to use deception in an experiment? Often necessary, otherwise subjects will not act as they normally would.Milgram: “Learning & punishment” [would not have continued if knew it was really about compliance.]
Why might you use a confederate in an experiment? Appear to be fellow subjects, but are actually in league with experimenter Can help with deception [Milgram]Can be used to create group pressure [Asch] Can be used to vary the conditionsAsch: what happens if one person bucks the majority?
Why might you use a confederate in an experiment? What happens if one by-stander comes to the victim’s aid?
What are the main components of classic experimental design, why is each important? Treatment group & Control group, Pre-test & Post-test
Occasionally, experimenters do not use classical experimental design. Why not, and how can this be justified?
