Conducted in an enivronment where the variables are carefully controlled. Participants are aware that they are taking part in a study, but don't always know the aims of the study. Laboratory studies can be conducted in a non-experimental way e.g. as an observation.
- It is easy to replicate the study because it is so carefully controlled - high in reliability
- High in internal validity as the researcher can be sure that the effects of the IV are in fact due to the DV
- Low in ecological validity because the lab setting is not reflective of everyday life or the IV or DV may not be reflective of tasks we do in everyday life either
- Demand characteristics might occur
