- Studies said to be lacking in this are those where it is difficult to say with any certainty what the cause of the results is
- Demand Characteristics
- Cues in the environment that help the participant work out what the research hypothesis is
- This means their behaviour is different from what they would normally do
- Results less valid
- Experimenter/investigator effects
- When the researcher inadvertently influences the results by unconsciously revealing the aim of the study
- Behaviour of the participants is not valid as it has changed in some way
- Social Desirability
- Tendency for people to present themselves in the best possible light
- People may lie/not be completely honest as they want to make themselves seem better
- Difference in what people say and what they do
- Ecological Validity
- The extent to which the methods, materials and setting of the study reflect the real life situation of interest.
- Studies low in this refer to the fact that participants behaviour is different from normal
- Population validity
