Factorial Design
|
Experiment in which more than one independent variable is manipulated
|
|
Independent sample
|
Each condition of the independent variable is experienced by one group of participants
|
|
Matched pairs
|
Each participant in one group/condition is paired on specific variables with a participant in another group/condition.
|
|
Repeated measures
|
Each participant experiences all levels of the independent variable.
|
|
Related design
|
Design in which individual scores in other conditions
|
|
Single participant
|
Design in which only one particpant is tested in several trials at all independent variable levels
|
|
Unrelated
|
Design in which indivdual scores in one condition cannot be paired or linked in any way with individual scores in any condition
|
|
Independent Variable
|
Variable which expeimenter manipulates in an experiement and which is assumned to have a direct effect on the dependent variable
|
|
Order Effects
|
A confunding effect caused by experiencing one condition ,then another such as a practice.
|
|
Particpant Variables
|
Person variables differing in proportion across different experimental groups and possibly confunding results
|
|
Placebo group
|
Group of participants that don't recieve the critical "treatment" but everything else the experimental group recieves.
|
|
Pre test
|
Measure of particpants before an experiment in order to balance or compare groups , or to assess change by comparison with scores after the experiment
|
|
Randomisation
|
Putting stimulus items or trial types into random order for the purpose of elimination of the order effects.
|
|
Standardised Procedure
|
Testing or measuring behaviour with exactly the same formalised routine for all particpants.
