- Experimental Methods
- Laboratory Experiment
- Def. Conducted in an artificial environment in attempt to control all variables except IV
- Advantages
- High levels of control
- Possible to establish casual relationships between variables
- Disadvantages
- Artificial so may lack ecological validity
- Pps behaviour can alter to what it would be like in real life as they know they're being studied
- Demand characteristics
- Field Experiment
- Def. Behaviour studied in natural environment but IV still manipulated and DV measured
- Advantages
- Natural environment gives it ecological validity
- Demand characteristics avoided as Pps don't know they're being studied
- Disadvantages
- Lack of control means extraneous variables can effect the results
- Ethical issues can be raised as Pps have not consented
- Quasi/natural Experiment
- Def. The IV is not manipulated by researcher but occurs naturally
- Gender, Age, Law
- Advantages
- Only way to study relationships that would be unethical to manipulate
- Can't make someone a criminal to test the effect it had
- Only way to study relationships that would be unethical to manipulate
- Disadvantages
- No control over extraneous variables
- Def. The IV is not manipulated by researcher but occurs naturally
- Laboratory Experiment
