Cards in this deck (12)
- 1What are the four types of experiments?Laboratory, Field, Natural, Quasi
- 2Explain key functions of laboratory experiments. (3)The researcher has full control over the IV and EV.
Done in a controlled environment.
Participants are randomly allocated to the groups.
Delibrate manipulation of the IV.
Can easily be repeated. - 3What are the strengths of laboratory experiments? (2)Control - over EV , if all other variables other than IV are controlled successfully or eliminated. cause and effect will be established
Replication- can easily be carried out again, if the findings are the same then confidence in the experiment goes up - 4What are the weaknesses of laboratory experiments? (2)Loss of ecological validity- high level control over the environment, an experiment can become artificial, results may not generalize to the outside world.
Demand Characteristics- when participants try to make sense of research situations and act accordingly. natural behavior is affected. - 5Explain the key functions of a field experiment.Naturally occurring surroundings.
The researcher still has control over the IV. - 6What are the strengths of a field experiment?Improved ecological validity.
Reduction of demand characteristics. - 7What are the weaknesses of a field experiment? (2)Loss of control of EV (extraneous variables)
Ethical issues- no informed consent. - 8What are the key functions of a natural experiment? (3)Natural.
Different from a field experiment.
Experimenter has no control over the IV.
Have to use a naturally occuring IV. - 9What are the weaknesses of a natural experiment? (2)No control.
Less evaluation. - 10What are the strengths of a natural experiment?Only ethical way.
- 11What are the key functions of a quasi experiment? (3)It's an almost experiment
the variables simply exist for example, being old or young.
carried out under controlled conditions (control of EV)
It allows comparisons between different people. - 12What are the strengths of a quasi experiment?Allows comparisons.
