2.5: Misleading information Flashcards
A researcher carried out an experiment to investigate misleading information. Participants were shown a photograph in which a man and a woman were talking. The photograph was then taken away and the participants were asked questions about it. Participants were randomly allocated to condition one or condition two.
Participants in condition one were asked:
Question A “How old was the youth in the photograph?”
Participants in condition two were asked:
Question B “How old was the man in the photograph?”
Name an appropriate experimental design which could be used in this experiment.
Explain why a repeated measures design would be unsuitable to use in this experiment (4 marks)
Independent measures design

Explain why a repeated measures design would be unsuitable to use in this experiment (4 marks).
Independent measures design.
A repeated measures design could not be used, because participants would take part in both conditions.
This would be inappropriate, because their answer to one question would affect their answer to the other question

The photograph was then taken away and the participants were asked questions about it. Participants were randomly allocated to condition one or condition two.
Participants in condition one were asked:
Question A “How old was the youth in the photograph?”
Participants in condition two were asked:
Question B “How old was the man in the photograph?”
Explain why it would be appropriate to use a pilot study as part of this experiment (4 marks)
It would be appropriate to use a pilot study as part of this experiment, because in this experiment, it could be used to check how long the participant should be given to look at the picture, so that the timing could be changed if it was too long or too short

It could check the participants understand the questions asked and what they are required to do.
It could also be used to ask a few participants about their experience of taking part
A researcher carried out an experiment to investigate misleading information. Participants were shown a photograph in which a man and a woman were talking. The photograph was then taken away and the participants were asked questions about it. Participants were randomly allocated to condition one or condition two.
Participants in condition one were asked:
Question A “How old was the youth in the photograph?”
Participants in condition two were asked:
Question B “How old was the man in the photograph?”
In this experiment, participants were asked to look at a photograph rather than watch a live conversation. Explain one strength and one limitation of carrying out the experiment in this way (4 marks)
One strength is control of variables.
For example, the same pictures could be shown for the same amount of time

One strength is control of variables.

One limitation
One limitation is lack of validity.
The findings cannot be generalised to real life situations where other factors such as changing facial expressions and gestures could be relevant
