Artificial environment where extraneous variables are controlled to ensure any change in the DV is caused by the IV. Participants are randomly allocated to conditions
1 of 8
What is an example of a laboratory experiment?
Asch's 3 lines experiment on majority conformity
2 of 8
Strength: high level of control
EVs are controlled so causal relationship can be assumed between IV and DV
3 of 8
Strength: reliable
Conditions created can be replicated
4 of 8
Strength: Accurate
Variables can be measured accurately with tools in lab setting, otherwise impossible to do so in a field experiment
5 of 8
Limitation: lacks ecological validity
Artificial setting may not mirror real life, possible unnatural behaviour
6 of 8
Limitation: demand characteristics
High level of control may mean the aim is guessed and behaviours may be altered from PCPs
7 of 8
Limitation: experimenter bias
expectation may affect interaction with PCPs or alter interpretation of results
