2(a) State two diagnostic criteria of gambling disorder. 2
AO1
Syllabus 1.3.1 diagnostic criteria (ICD-11) of impulse control disorders: –
kleptomania – pyromania – gambling disorder.
Marks: Award 1 mark for each correct criterion (in bold) 2 max.
Definitive answer (ICD-11):
Essential (Required) Features:
• a persistent pattern of gambling behaviour, which may be predominantly
online or offline, manifested by all of the following:
– impaired control over gambling behaviour
– increasing priority given to gambling behaviour; precedence over
other life interests and daily activities;
– continuation or escalation despite negative consequences
• the pattern of gambling behaviour may be continuous or episodic and
recurrent but is manifested over an extended period of time (e.g. 12
months).
• the pattern of gambling behaviour results in significant distress or
impairment in personal, family, social, educational, occupational, or
other important areas of functioning.
Note: 0 marks for general features of ICD’s (i.e. that could apply to any ICD).

combination of these (1 mark) over a period of time to see how many
diagnostic features of the gambling disorder are evident (2 marks).
• case study of one person (1 mark) to see how many diagnostic features
of the gambling disorder are evident (2 marks).

Weaknesses:
• the gambler may not provide honest answers to questions (1 mark)
• perhaps to hide the extent of their gambling addiction (+1 marks)
• such as their behaviour over a recent time period, saying that they have
not gambled when they have (+1 mark)
• researcher bias in interpretation of answers if open questions used (1
mark) so incorrect measure and implication for treatment of gambling
disorder (2 marks)
• if closed questions used they might not account for individual
differences/unique cases (1 mark) which would have implications for the
measure/treatment of the gambler (2 marks)

3 From the key study by Hall et al. (2010) on choice blindness for food
items:
3(a)(i) Identify two ways in which deception was used in this study. 2
AO1
Syllabus: 2.3.3 Key study for choice blindness when tasting and smelling food
items: Hall et al. (2010).
Marks: Award 1 mark for each correct identification.
Definitive answers: (quoting the study):
(i) we recruited the participants by asking them whether they were willing to
take part in a ‘quality control’ test of the jam and tea assortment at
the store
(ii) we presented ourselves as being independent consultants contracted
to survey the quality of the jam and tea assortment in the shop
(iii) unknown to the participants, on certain trials, we used a card magic
trick to covertly exchange one face for the other
(iv) we created two sets of ‘magical’ jars, lidded at both ends, and with a
divider inside. These jars thus looked like normal containers but were
designed to hold one variety of jam or tea at each end and could easily
be flipped over to execute a switch.
3(a)(ii) Explain why each of these deceptions was necessary. 2
AO1
Marks: Award 1 mark for each correct reason. Reasons below relate to ways
in (a)(i).
(i) necessary because participants would realise that they were participating
in a study
(ii) necessary because participants would realise that they were
experimenters conducting a study
(iii) participants have to be deceived about the using the magic card trick
otherwise the study would simply not work
(iv) participants have to deceived about the ‘magical jars’ otherwise the study
would simply not work.
Note: for 2 marks any two reasons, not matched; also one detailed reason.
3(b) Suggest one effect on the results if deception had not been used in this 2
study.
AO2
Marks: Award 2 marks for an appropriate suggestion stated and applied to
study with detail / elaboration / example. Award 1 mark for an appropriate
suggestion identified but not applied.
Answers may include (other appropriate responses to be credited):
• the study would be confounded (1 mark) participants would realise they
were in a study about choice blindness and perhaps respond to demand
characteristics (2 marks)
• cause and effect could not be established (1 mark) participants would
realise that they were being tricked e.g. by the jars or card trick and not
behave as they normally would (2 marks)
3(c) Explain one strength and one weakness of the use of field experiments 4
to investigate choice blindness.
AO3
Marks: Up to 2 marks for each strength and up to 2 marks for each weakness:
Award 2 marks for an appropriate strength/weakness stated and applied as
required by the question with detail / elaboration / example.
Award 1 mark for an appropriate strength/weakness stated but not applied
Answers may include (other appropriate responses to be credited):
Strengths:
• a field experiment has an IV, DV and controls (1 mark) and is just as
important in studies of choice blindness as in any other; e.g. of IV and DV
in this study (2 marks)
• often participants do not know they are taking part in a study and so
behave more naturally (1 mark) in the Hall et al. study consent given at
the end (2 marks).
• a field experiment is the best location (1 mark) because most consumer
behaviour (e.g. shopping) takes place in the real world and so studies
should be conducted in the real world (rather than in a laboratory) (2
marks).
• Weaknesses:
• a field experiment may have variables that are more difficult to control
than a laboratory experiment (1 mark) with any retail atmospheric variable
as an example (2 marks)
• isolating one variable to study (i.e. the IV) when many other variables are
controlled may not be appropriate (1 mark) when in the real-world
individual aspects of choice blindness never occur in isolation (2 marks)

AO1
Syllabus: 2.4.1 gift-wrapping including beliefs of giver and recipient: why gifts
are wrapped, types of wrapping.
Marks: Award 1 marks for ‘way’ or type plus 1 mark for elaboration/example
Most likely answer:
• wrapped in a traditional manner where the gift meets expectations of
looking like a gift with ribbons, bows, etc. (1 mark)
• wrapped in a non-traditional manner where it may be difficult to
determine that the gift is actually a gift, for example, through the use of
plain brown paper (1 mark)
Note: award 1 mark if both types are identified only.
4(b) Suggest how an unstructured observation can be used to investigate 2
gift-wrapping behaviour.
AO2
Marks: Award 2 marks for an appropriate suggestion and applied to study with
detail / elaboration / example. Award 1 mark for an appropriate suggestion but
not applied.
Answers may include (other appropriate responses to be credited).
• an unstructured observation would have no pre-determined response
categories (1 mark) and the observer lists gift-wrapping behaviours as
they are performed (2 marks)
• an unstructured observation could be done in different locations (1 mark)
such as in a gift shop compared to at home wrapping a gift for a friend (2
marks)

Award 1 mark for an appropriate strength stated but not applied.
Answers may include (other appropriate responses to be credited):
Strengths:
• a covert observation means the person is unaware they are being
observed and so behaves naturally (1 mark) wrapping a gift as they
usually would (2 marks)
• observations can have more than one observer, so reliability of an
observation can be checked (1 mark) perhaps all agreeing that a gift is
non-traditional (2 marks)
• a structured observation means that observers know exactly what they
are looking for (1 mark) to see what features are included in a traditional
wrapping, such as a bow (2 marks).
• A naturalistic observation means that the participant is in a natural
environment and unaware (1 mark) that their gift-wrapping behaviour is
being observed (2 marks)

children’s pain.
AO1
Syllabus: 3.3.2: Key Study on comparing pain assessments by doctors,
parents and children: Brudvik et al. (2016).
Marks: Award 2 marks for a detailed outline. Award 1 mark for a partial
outline.
Definitive answers (from the study):
• emergency department physicians significantly underestimate pain (1
mark) from all medical conditions in paediatric patients ≥3 years old,
especially from wounds, infections and soft tissue injuries, but less from
fractures (2 marks).
• physicians’ pain assessments improve with increasing levels of pain
(1 mark), but still, hardly half of the children with severe pain receive pain
relief (2 marks).
• physicians should be cognizant that they are likely to underestimate
children’s pain (1 mark) children’s self-reports through age-appropriate
pain scales and parents’ assessments are important in order to improve
pain management in the emergency department (2 marks).
Note: Answers must be those from the study, not candidate suggestions.
Note: findings (results) can only support a conclusion
5(b) Suggest one way pain in children could be measured without using self- 2
report pain rating scales.
AO2
Marks: Award 2 marks for an appropriate suggestion stated and applied to
study with detail / elaboration / example. Award 1 mark for an appropriate
suggestion but not applied.
Answers may include (other appropriate responses to be credited).
• observation of non-verbal cues (1 mark) such as grimaces, rubbing,
limping (+1 mark).
• observation of audible expressions (1 mark) groans, ‘ahhh’s’, crying (+1
mark)
• observation of negative affect (1 mark) irritable, bad mood, misbehaving,
not sitting still, etc (+1 mark)
• self-report by the child (1 mark) expressing how much it hurts (+1 mark)
(which is not a rating scale)
• clinical interview by physician giving subjective estimate of child’s pain (1
mark) e.g. child is asked to describe their pain (2 marks).
Note: UAB although a rating scale, is not a self -report and so is creditworthy.
Note: MPQ and PPQ use rating scales. All visual analogue scales use rating
scales (as do ‘smiley faces’)

marks)
• using a case study provides practitioners with more information about the
disorder and reasons for it occurring (1 mark) e.g. Jacab et al. (2006)
discussed key symptoms perhaps present in all malingerers/Munchausen
syndrome (2 marks)
• using a case study of a person with the disorder is perhaps the only way
it can be studied (1 mark) because an experiment would be impossible

Definitive answers (quote from study):
We have distinguished 4 essential causes of accidents:
• insufficient supervision (1 mark) inadequate control of whether the
worker has followed the correct code of practice (2 marks)
• poor workplace organisation (1 mark) faults in the determination of
workplace organisation system, e.g. inadequate personal protection, too
high a pace of work, incorrect work procedures, failure to nominate a
person responsible for group tasks) (2 marks)
• technical factors (1 mark) defects in technical object, failure to meet the
predetermined technical requirements (2 marks),
• worker inadvertence (or worker error) (1 mark) individual error of the
worker difficult to predict by the supervisor, resulting e.g. from an
inadvertent action (2 marks)
• Swat also adds (quote from study) Insufficient supervision was found in
as much as 89% of cases studied. Poor workplace organization was
involved in 40% of the accidents. Worker inadvertence constituted an
essential cause of 14% of accidents. Technical factors were responsible
for only 11% of the cases studied. It should be added that the mechanism
of 9 (13%) accidents could not be clearly explained.
Note: correct percentage of causes credited as +1 mark)

• reported accidents may have to meet certain criteria so ‘minor’ accidents
are not reported (1 mark) for example, a person may have to be taken to
hospital or take time off work for the accident to be counted (2 marks)
• reported accidents may result in a shut-down or halt in production whilst
the cause is investigated (1 mark) which the company would not want, so

Can be made:
• the study included a range of four very different trades (1 mark) foundry,
machinery plant, meat processing and furniture (2 marks)
• if accidents in different trades can be categorised relatively easily then
perhaps they apply to many other trades (1 mark) e.g. ‘poor
housekeeping’ was a very common cause of accidents (2 marks)
Cannot be made:
• just because the finding from one study identifies common elements it
does not mean that those elements will be found elsewhere (1 mark)
‘housekeeping’ for example might be key in the four trades in the study,
but no other trade or even in those same trades (2 marks).

• profit-sharing does not apply in all organisations or in organisations where
there is no profit (1 mark) there is no profit in a public health service or
police or fire service for example (2 marks)
• profit-sharing is an extrinsic motivator and it is argued that it can
decrease intrinsic motivation when workers work only for money (1 mark)

Syllabus: 2.3.2 Choice heuristics. Point of purchase decisions including
multiple unit pricing and suggestive selling, including a study, e.g. Wansink et
al. (1998).
Answers are likely to include (other appropriate responses to be credited):
Suggestive selling is where the salesperson asks the customer if they would
like to include an additional purchase or recommends a product which might
suit them/their needs/usage. It is also known as add-on selling, up-selling and
cross-selling. Wansink (1998) for example looked at suggestive selling using
slogans such as ‘buy Snickers bars for your freezer’ and ‘buy 18 Snickers
bars for your freezer’. Sales (of Snickers bars) increased with both of these
anchors.

AO2
Syllabus: 3.3.3 Managing and controlling pain: biological treatment:
biochemical. Alternative treatments: acupuncture; stimulation therapy/TENS.
Description:
Note: question is chronic pain NOT acute pain.
biochemical techniques:
• peripherally acting analgesics act on the peripheral nervous system (e.g.
aspirin, ibuprofen, paracetamol).
• centrally acting analgesics work directly on the central nervous system
(e.g. morphine).
• local anesthetics can work when ‘rubbed in’ but are more effective when
injected into a site (e.g. tooth extraction, epidural).
Simulation/TENS:
• stimulation therapy uses counter-irritation that directs attention away from
the stronger pain. Transcutaneous electrical nerve stimulation (TENS) is
self-administered. Electrodes are placed on the skin near where the
patient feels pain and very mild electric shocks are given, causing
distraction.

Example: For the biochemical treatment group I used a peripherally acting
local anaesthetics that numbed the area when ‘rubbed in’ so that participants
were not injected (invasive) or given orally given any drug. This would make
the treatment similar to stimulating the skin with TENS.

Answers are likely to include (other appropriate responses to be credited):
Achievement motivation: McClelland’s achievement–motivation theory (1961)
suggests that we have three work-related needs: Need for achievement –
the need to get a job done, to master a task, to be successful. People want to
achieve on the basis of their hard work and effort rather than on the basis of
luck. Need for affiliation – the need to be liked and accepted by other
people; effort is applied to creating and maintaining social relationships and
friendships. Need for power – this concerns being influential in the lives of
others and also in the control of others; the need for discipline is important.
