Research Design Experimental Designs

Front 1

Factorial Design

Back 1

Experiment in which more than one independent variable is manipulated

Front 2

Independent sample

Back 2

Each condition of the independent variable is experienced by one group of participants

Front 3

Matched pairs

Back 3

Each participant in one group/condition is paired on specific variables with a participant in another group/condition.

Front 4

Repeated measures

Back 4

Each participant experiences all levels of the independent variable.

Front 5

Related design

Back 5

Design in which individual scores in other conditions

Front 6

Single participant

Back 6

Design in which only one particpant is tested in several trials at all independent variable levels

Front 7

Unrelated

Back 7

Design in which indivdual scores in one condition cannot be paired or linked in any way with individual scores in any condition

Front 8

Independent Variable

Back 8

Variable which expeimenter manipulates in an experiement and which is assumned to have a direct effect on the dependent variable

Front 9

Order Effects

Back 9

A confunding effect caused by experiencing one condition ,then another such as a practice.

Front 10

Particpant Variables

Back 10

Person variables differing in proportion across different experimental groups and possibly confunding results

Front 11

Placebo group

Back 11

Group of participants that don't recieve the critical "treatment" but everything else the experimental group recieves.

Front 12

Pre test

Back 12

Measure of particpants before an experiment in order to balance or compare groups , or to assess change by comparison with scores after the experiment

Front 13

Randomisation

Back 13

Putting stimulus items or trial types into random order for the purpose of elimination of the order effects.

Front 14

Standardised Procedure

Back 14

Testing or measuring behaviour with exactly the same formalised routine for all particpants.
