Practise Edexcel Psychology questions on Hoefelmann et al. (2006), using sleep-behaviour evidence to evaluate sample and research-method decisions.
In your studies on biological psychology, you will have learned about one of the following contemporary studies:
- McDermott (2008)
- Hoefelmann et al. (2006).
Chosen study
Explain one improvement that could be made to the sample used in your chosen contemporary study. (2)
AO1 (1 mark), AO3 (1 mark)
Credit one mark for accurate identification of an improvement (AO1)
Credit one mark for justification/exemplification of the improvement
(AO3)
For example:
McDermott (2008)
- The sample could have included women as well as men to make
the results about MAOA activity and aggression more
generalisable (1), as the results about the effect of MAOA activity
on the willingness to punish others would be more representative
of both genders (1).
Hoefelmann et al. (2006)
- They could have used a range of students to include those who
went to class during the daytime to increase generalisability (1),
as the results on sleep quality would be more representative of all
high school students (1).
Look for other reasonable marking points.
