10(b)(i) Describe this psychological knowledge. 4 Syllabus: 2.3.1 Consumer decision-making. strategies of consumer decision- making focusing on explanations and examples of compensatory, non- compensatory and partially compensatory strategies including explanations and examples of each. Answers are likely to include (other appropriate responses to be credited): Study by Jedetski (2002) outlines compensatory decision strategies: an attractive or high value on one attribute can compensate for an unattractive or low value on another attribute. For example, attractive attributes (e.g. of coat quality) can compensate for unattractive attributes (e.g. high coat cost). non-compensatory decision strategies: consumers making choices consider attributes sequentially, and benefits on some attributes may not overbalance shortfalls on others. Three strategies apply: • lexicographic: if the first coat has high value attributes, there is no reason to look further. • satisficing: we select the first option that appears to meet the need (see above). • elimination by aspects: sets a cut-off value and any coat not meeting the desired value is eliminated. Partially compensatory strategies combine aspects of the above models. Note: do not allow del Campo et al who looked at choice heuristics (recognition versus ‘take-the-best’).

Question

Mark scheme

11(b)(i) Describe this psychological knowledge. 4 AO2 Syllabus: 3.3.1 Types and theories of pain. functions of pain; types of pain: acute and chronic pain. Focus on phantom limb pain and mirror treatment to include a case study, e.g. MacLachlan et al. (2004). Answers are likely to include (other appropriate responses to be credited): Mirror treatment involves the use of a mirror box. The patient moves the good limb and observes the reflection. As the patient sees the good hand/leg moving it appears as if the phantom limb is also moving. If there is no pain in the good limb, there is no pain in the phantom limb. Study by MacLachlan et al. (2004) could be mentioned. Quote ‘We present the first case study of the use of ‘mirror treatment’ in a person with a lower limb amputation who was reporting PLP at the time of treatment. During the intervention there was a significant reduction in his PLP, an increase in sense of motor control over the phantom and a change in aspects of the phantom limb that was experienced.’ Marks Description 3–4 The knowledge is appropriate. Relevant points are correctly described in good detail. 1–2 Basic points are identified with some elaboration and understanding.

Alternatively could include: Location of treatment: in participant’s home or in laboratory? Behavioural/observational measures of pain: (for example) a patient’s facial expressions ‘happy’/shows some discomfort/pain (grimaces). 11(c)(i) Explain one reason for your choice of location for the study. 2 AO2 Candidates must use the location stated in (a). Award 2 marks: reason is given and applied to the plan Award 1 mark: reason is given without being applied to the plan Example • location of a laboratory or hospital room because the environment can be controlled for the observation (1 mark) related to study (2 marks) • location of a home because this is where the person will be when practising treatment and it is natural for the participant (1 mark) related to study (2 marks) Trace ID: PC-A916BF1E1A Re-uploading, mirroring or re-hosting this file on any other website or domain is unauthorised and traceable.

Award 2 marks if an appropriate reason is given and justified. Award 1 mark if an appropriate reason is given but not justified. Example: • behavioural categories were used because they could be agreed and defined before the observation started (1 mark) related to plan (2 marks). • behavioural categories were used because each observer would know exactly what they were looking for, reducing ambiguity and increasing inter-rater reliability (1 mark) related to plan (2 marks).
