Features of a lab, +/- and why they use them?
-> Measure/research something hard to do. May be unethical to do using a different RM.
- Standardised procedure.
- Operationalised variables.
- Participants were randomly allocated to IV group.
- Highly controlled conditions.
- Manipulate IV and measure DV.
Easy to replicate due to standardised and high controls.
Demand characteristics - reduce internal validity.
Low ecological validity - artificial setting.
