AO1 (2 marks), AO3 (2 marks)
Credit one mark for accurate identification of each weakness (AO1).
Credit one mark for justification/exemplification of each weakness
(AO3).
For example:
- Capafóns et al. (1998) only used participants who were afraid of
flying in their study (1), therefore the results may not be the
same for other phobias so cannot be generalised to systematic
desensitisation for all phobias (1).
- The participants replied to a media campaign so volunteered for
the study which may cause the sample to be biased (1), as only
those who were ready to have their phobia of flying treated may
have responded to the media campaign (1).
Look for other reasonable answers.
