Johnson + Scott used a lab experiment method. What are 2 limitations of using this method? | Increased chance of demand characteristics - participants are aware they are taking part in a study and so may change their behaviour - reducing the internal validity OR Low ecological validity - research takes place in artificial setting, meaning it is harder to generalise to real life settings |
