Research Methods
- Experimental Method
- Lab Experiment
- Controlled and
scientific
- The effects of cofounding variables are minimised
- Strict control allows for replication of the study
- Easier to establish cause and effect due to control of
extraneous variables
- Artificial, lack ecological validity
- Demand characteristics may occur, resulting in
biased results
- Deception is often used, making informed
consent difficult
- Field Experiment
- Less easy to establish
cause and effect as it
isn't always possible to
control all variables
- More ecological validity, they can be generalised to real life
- Demand characteristics can be avoided as
participants don't know they're in a study
- Participants often do not know they are in a study
and often can't be debriefed.
- Natural Experiment
- It is possible to study variables that it
would be unethical to manipulate
- Hard to establish cause and
effect as you can't randomly
allocate participants so
participant variables may
cofound results
- Some groups of interest are hard to find
- Deception is often used and confidentiality may be
compromised if the community is identifiable
- High ecological validity, represents real life
- Participants may not know they are being
studied reducing eliminating demand
characteristics
