7.2: Validity Flashcards
A stratified sample of participants were shown a tray containing 30 unrelated items for 30 seconds, after which time the tray was removed from sight. Half the participants were made moderately anxious, by wearing fake electrodes, which they were told would give them electric shocks for answers they got wrong. The other participants had low anxiety levels, through being told that the fake electrodes were merely monitoring bodily processes. Participants were instructed to recall as many items as possible.

The validity of the data could be assessed through face validity

The validity of the data could be assessed through face validity, what?
The validity of the data could be assessed through face validity, the degree to which the data looks like what it claims to measure
A psychologist wanted to see if verbal fluency is affected by whether people think they are presenting information to a small group of people or to a large group of people.
The psychologist needed a stratified sample of 20 people. She obtained the sample from a company employing 60 men and 40 women.
The participants were told that they would be placed in a booth where they would read out an article about the life of a famous author to an audience. Participants were also told that the audience would not be present, but would only be able to hear them and would not be able to interact with them.
There were two conditions in the study, Condition A and Condition B.
Condition A: 10 participants were told the audience consisted of 5 listeners.
Condition B: the other 10 participants were told the audience consisted of 100 listeners.
Each participant completed the study individually. The psychologist recorded each presentation and then counted the number of verbal errors made by each participant.

The psychologist could use face validity to check the validity of the data she collected in this study by asking other people if verbal errors are a good measure of verbal fluency

Briefly explain how the psychologist could use concurrent validity to check the validity of the data she collected in this study (2 marks)
The psychologist could use concurrent validity to check the validity of the data she collected in this study by giving participants an alternative/established verbal fluency test and checking to see that the two sets of data are positively correlated
