Document Summary

Internal validity - a type of evaluation of your experiment. It asks whether your iv is the only possible explanation of the results shown for your dv. History - if historical events that could affect the dv occur between two measurements in a repeated measures design. Maturation - if participants change simply due to the passage of time (e. g. tiredness, boredom, hunger). Testing - if participants respond differently on the second measure of a dv simply because they"ve been tested before. Practice effect - a beneficial effect on a dv measurement caused by previous experience with the dv. Reactive measures - dv measurements that actually change the dv being measured (e. g. when you know your attitude is being measured, you might change your attitude to fit what you think the experimenter wants). Nonreactive measures - dv measurements that do not influence the dv being measured.
