|
constancy of conditions |

attempts to eliminate the confounding effects of order of presentation by requiring one fourth of the subjects to be exposed to the effects of treatment A first, one fourth to treatment B first, one fourth to treatment C, and one fourth to treatment D |
|
|
debriefing |
the process of providing subjects with all pertinent facts about the nature and purpose of the experiment AFTER IT'S COMPLETION |

|
|
|
field experiments |
research projects involving experimental manipulations that are implemented in a natural environment
|
|
|
Internal validity |
exists to the extent that an experimental variable is truly responsible for any change in the dependent variable |
|
|
Manipulation check |
a validity test of an experimental manipulation to ensure the manipulation does produce differences in the independent variable |
|
|
history effect |
occurs when some change other than the experimental treatment occurs during the course of an experiment that affects the dependent variable |
|
|
cohort affect |
