- EXPERIMENTS
- LAB EXPERIMENT
- + possible to control the environment making it reliable and easy to replicate .
- + artificially controlled setting, means they are more likely to require consent so no ethical issues.
- - behaviour seen may lack realism due to artificial settings.
- - as participants know they are being observed they may respond with demand characteristics.
- FIELD EXPERIMENT
- + natural environment means behaviour is natural and realistic increasing ecological validity
- + participants may not know they are being observed so no demand characteristics improving experimental validity.
- - environment is less controlled so chance of extraneous variables.
- - gaining consent is difficult if they are not aware of the observation - ethical issues
- NATURAL EXPERIMENT
- + The change or difference being investigated in the IV is not being controlled by the experimenter due to less experimenter bias.
- + any changes in the DV are more likely to be realistic and not artificially created.
- - as the experimenter has no control of the IV there can be no direct link between cause and effect - so low reliability.
- QUASI EXPERIMENTS
- + the IV is naturally occurring between people meaning higher realism.
- - can only be used where a naturally occurring difference can be identified
- LAB EXPERIMENT
