How to Evaluate a Study - Using Craik and Tulving (1975 Levels of Processing)
A question that asks you to evaluate a study in AS
Psychology will roughly be around 5 marks, to achieve full marks you should
make a developed point of at least 4 of these areas:
1.
Generalisability
o
How many participants
took part in the study?
o
Can this be generalised to the rest of the
population?
Craik and Tulving: Does not represent the
whole population as there were only 20 participants
2.
Reliability
o
Is a controlled procedure used?
o
Would it be easy to repeat the study?
Craik and Tulving: There is a high
reliability as the study took place in a lab
3.
Application
to real life
o
How does society benefit from the study?
Craik and Tulving: Can be used to benefit
students who are studying for their exams as they know to revise the content
semantically by making sure they have a full understanding of their work.
4.
Validity
o
Does the study test what it set out to test?
o
Is the study set in an artificial or real
setting?
o
Are there any factors that may affect the
results? (confounding variables)
Craik and Tulving: The study has a high
validity as being conducted in a lab there was a high level of control meaning
there was a small chance of confounding variables affecting the results.
5.
Ecological
Validity
o
Was the task conducted realistic?
o
Was a real life setting used? (lab experiment or
field experiment?)
Craik and Tulving: Has a low ecological
validity as the study took place in an artificial environment as it was a lab
experiment meaning the behaviour experience was not realistic.
You can also talk about whether the study meets ethical guidelines, I will be making a seperate resource on this.
