MET Experiment Types Flashcards
What are the key features and an example of a laboratory experiment?
Set-up
Controlled conditions
Manipulate IV
Memory experiments
What are the strengths of laboratory experiments?
Best control of EVs
What are the limitations of laboratory experiment?
Least ecological validity and population validity
More participant reactivity
What are the key features and an example of a field experiment?
Where behaviour usually occurs
Manipulate IV
Hofling study of obedience in nurses
What are the strengths of field experiments?
Better population validity and ecological validity
Low participant reactivity
What are the limitations of field experiments?
Less control over EVs than lab experiments
What are the key features and an example of a natural experiment?
Where behaviour usually occurs
IV is an event, not manipulated
Induction of TV causing violence
What are the strengths of natural experiments?
Good ecological validity and population validity
What are the limitations of natural experiments?
Less control over EVs
Not ‘true’ experiments as an IV is not manipulated
No random allocation
Rarely occur
What are the key features and an example of a quasi experiment?
IV is a pre-existing group difference
IV can not be manipulated
Gender differences in conformity
What are the strengths of quasi experiments?
Can be conducted under lab conditions
What are the limitations of quasi experiments?
Not ‘true’ experiments as IV is not manipulated
No random allocation
