Q

What are laboratory experiments

A

Experiment that takes place in a controlled environ within which researcher manipulated IV and records effect on DV while maintaining strict control of EVs

Q

Strengths of lab experiments

A

-high control over EVs=more certain that change in IV caused change in DV (cause and effect)
-replication more possible due to high level of control

Q

Limitations of lab experiments

A

-environ artificial=lack generalisability to everyday life(low external validity)
-pps usually aware being tested, cause demand characteristics
-artificial tasks=low mundane realism

Q

Strengths of field experiments

A

-higher mundane realism-environ like everyday life=generalisable
-reduced demand characteristics if pps unaware being studied

Q

Limitations of field experiments

A

-loss of control of EVs means cause and effect between IV and DV more difficult to establish
-precise replication often not possible
-ethical issues if pps unaware being studied cannot give consent

Q

What are natural experiments

A

Experiment where the change in IV is not brought about by researcher but would have happened regardless, researcher records effect on DV

-opp for research not otherwise undertaken for practical/ethical reasons
-high external validity as involve the study of real life issues

Q

Limitations of natural experiments

A

-event may only happen rarely=cannot generalise
-pps not randomly allocated to conditions, less sure whether change in IV caused change in DV

Q

Strength of quasi experiments

A

Often carried out under controlled conditions=control over EVs so better able to establish cause and effect relationship between IV and DV
