7.2: Validity Flashcards
Researchers investigating the cognitive biases of gamblers decided to ask participants to say out loud what they were thinking while playing on a roulette wheel at a casino. They recorded what the participants said using a small microphone. They then analysed the recordings using content analysis.
Explain why the methodology used could be argued to lack validity (4 marks)
The methodology used could be argued to lack validity, because internal validity (the degree to which a study investigates what it claims to investigate) is reduced by investigator effects

What could this affect?
This could affect the degree to which participants give full and honest answers about what they are thinking while playing roulette

Demand characteristics could also occur, where what?
Demand characteristics could also occur, where participants, as they are aware they are taking part in an investigation, give answers about what they’re thinking that they think the researchers want to hear, and not necessarily their true answers

What could this too do?
This too could reduce internal validity
