General Marking Guidance
            •   All    candidates        must     receive     the      same
                treatment. Examiners must mark the first candidate in
                exactly the same way as they mark the last.
            •   Mark schemes should be applied positively. Candidates
                must be rewarded for what they have shown they can do
                rather than penalised for omissions.
            •   Examiners should mark according to the mark scheme
                not according to their perception of where the grade
                boundaries may lie.
            •   There is no ceiling on achievement. All marks on the mark
                scheme should be used appropriately.
            •   All the marks on the mark scheme are designed to be
                awarded. Examiners should always award full marks if
                deserved,   i.e.   if   the   answer   matches   the   mark
                scheme. Examiners should also be prepared to award
                zero marks if the candidate’s response is not worthy of
                credit according to the mark scheme.
            •   Where some judgement is required, mark schemes will
                provide the principles by which marks will be awarded
                and exemplification may be limited.
            •   When examiners are in doubt regarding the application
                of the mark scheme to a candidate’s response, the team
                leader must be consulted.
            •   Crossed out work should be marked UNLESS the
                candidate has replaced it with an alternative response.

           Credit one mark for an accurate statement.
           For example;

           Credit up to two marks for an accurate description.
           For example;
              •   The pseudo-patients took detailed notes about their experiences
                  with staff and patients on the ward in their diaries including what
                  kind of medication they were given (1). The written notes also
                  contained comprehensive details of patient behaviours that had
                  been misinterpreted by the ward staff (1).

           Credit one mark for each accurate identification of a strength (AO1)
           Credit one mark for justification/exemplification of each strength (AO3)
           For example;
              •   The pseudo-patients used standardised symptoms during the
                  admissions process, they all told the doctors they could hear
                  voices saying words such as ‘thud’ (1). This increases the
                  reliability of the study by Rosenhan (1973) as it allowed the
                  procedure to be retested a total of 12 times within the study (1).
              •   Quantitative data was gathered by pseudo-patients for the
                  number of tablets they were given and the number of times that
                  staff initiated conversation or contact with them (1). The
                  objectivity of this data strengthens the reliability of Rosenhan
                  (1973) results about institutionalisation as there is no subjective
                  interpretation required with numerical data which reduces
                  researcher bias (1).

           Credit up to two marks for an appropriate description in relation to the
           scenario.
           For example;
              •   Ashanti could undertake an online search of reputable psychology
                  sources that publish research about different types of family
                  therapy to gather a range of studies and articles (1). She would
                  need to use key terms such as ‘family therapy’ and ‘effective’ in
                  order to gather appropriate data relevant to her research topic
                  (1).

           Credit up to four marks for an accurate description in relation to the
           scenario.
           For example;
              •   First, Ashanti would need to gain fully informed consent from
                  Caspian for his family therapy sessions and potentially personal
                  information to be part of a case study (1). Ashanti could then
                  undertake a range of research activities with Caspian to complete
                  her case study, for example interviewing him about his thoughts
                  on family therapy (1) and using his medical case files that show
                  the course of his schizophrenia since he was first diagnosed, to
                  find evidence of progress and therapy effectiveness (1). Ashanti
                  could also attend a family therapy session with Caspian and make
                  observational records of the therapy to include in her case study
                  report about effectiveness (1).

           Credit one mark for an accurate identification of each weakness in
           relation to the scenario (AO2)
           Credit one mark for justification/exemplification of each weakness (AO3)
           For example;
              •   Ashanti may be biased towards wanting success for Caspian as he
                  is her patient so her case study could lack objectivity in reporting
                  about family therapy (1) which would reduce the reliability of her
                  research into effectiveness as her data would be skewed to her
                  personal belief and interpretation of Caspian’s experiences (1).
              •   The case study is based on Caspian’s unique experiences of family
                  therapy for his schizophrenia and is unlikely to be representative
                  of other families or mental health conditions (1), therefore the
                  findings about the effectiveness of family therapy would not be
                  generalisable to a wider population of patients undergoing this
                  therapy (1).

           For example;

                  they may have linguistic differences that impact on the wording
                  used by Andrezj to express the worries and concerns he had (1)
                  leading to the clinicians misunderstanding his feelings and
                  concerns about his symptoms due to seeing them through their
                  own cultural lens rather than from a culturally relative point of
                  view (1).

           the scenario (AO2).
           Credit one mark for justification/exemplification of the reason (AO3)
           For example;
              •   Andrezj’s diagnosis can be considered reliable as the two clinicians
                  both used the DSM for his diagnosis so there is inter-rater
                  reliability from the two separate clinicians diagnosing the same
                  mental health disorder for Andrezj (1), as shown by Brown et al.
                  (2001) who tested the DSM-IV for mood and anxiety disorders
                  finding that independent interviewers came to the same diagnosis,
                  so the DSM is a reliable diagnostic system (1).

           Credit up to four marks for an accurate description
           Anorexia nervosa
           For example;
              •   Learning theory would suggest that anorexia nervosa may be a
                  result of paying attention to role models who are thin and
                  retaining this body image (1). Imitating the ideal weight of role
                  models may be motivated by the positive reactions the media
                  gives ‘thin’ celebrities and the negative responses to being
                  overweight (1). Young people, often girls, may wish to be like
                  their role models and reproduce the idealised ideas of women
                  being of ‘thin’ shown in the western media (1), including social
                  media imagery that reflects westernised ideal body images of
                  women and pro-anorexia sites that positively reinforce sufferers
                  being underweight (1).
           Unipolar depression
           For example;
              •   The cognitive model suggests that unipolar depression is due to
                  cognitive errors that people make about themselves resulting in a
                  negative view of themselves (1) which is the result of a faulty
                  pattern of thought and irrational thinking that are considered to
                  be negative schemata and distorted processing of information (1).
                  The cognitive triad also suggests that a negative view of self, the
                  world and the future results in negative cognitive biases, such as
                  overgeneralisations based on limited evidence (1) creating an
                  individual’s negative self-concept involving how they see
                  themselves and think about themselves in relation to the outside
                  world (1).

           Anorexia Nervosa
           For example;
              •   CBT can challenge negative thoughts and helps question faulty
                  beliefs about weight and body image to develop positive self-talk
                  about food and weight (1). Pike et al. (2003) found CBT was more
                  effective than nutritional counselling in improving outcome and
                  preventing relapse in anorexia nervosa (1). CBT may not address
                  other influences in the onset of anorexia nervosa, for example the
                  impact of external factors such as role models in the media (1).
                  Becker et al. (2002) found that television influenced views about
                  body shape and/or weight which CBT may not consider when
                  addressing cognitive processes (1). Specialised cognitive
                  behavioural therapy (CBT-ED) is designed for people with eating
                  disorders but takes over 40 weeks which is time consuming (1),
                  so because CBT does not work immediately for patients with
                  anorexia nervosa this may result in high drop our rates reducing
                  the effectiveness of the treatment (1).
           Unipolar Depression
           For example;
              •   Cognitive behavioural therapy can be used in combination with
                  other treatments and is considered to be effective alongside
                  SSRI’s for treating unipolar depression (1). Wiles et al. (2013)
                  found that patients undertaking CBT with anti-depressant
                  medications saw a reduction in their unipolar depression
                  symptoms (1). Completing the homework tasks to reflect on their
                  experiences of depression when they are away from the therapy
                  session may be difficult for clients with depression (1) as these
                  tasks require a motivation that the clients may not feel due to
                  some of their symptoms, such as diminished interests in daily life
                  (1). CBT does not account for other influences for the onset of
                  depression, such as the role of neurotransmitters, so may not be
                  effective if depression is not just related to cognitive processing
                  (1) Cuijpers et al.’s (2013) meta-analysis of CBT effectiveness in
                  adults finding CBT was no more effective than drug treatment
                  when used alone but was most effective when CBT was combined

           AO1
           • Drug therapy is a biological treatment where the use of anti-psychotic
             drugs such as clozapine, aims to alter the chemistry in the brain.
           • Drug therapy is based on neurotransmitter explanations of schizophrenia,
             such as the dopamine hypothesis.
           • Drug therapy consists of anti-psychotic medication which suppresses
             hallucinations and delusions and can be used with anti-depressants.
           • Some anti-psychotic drugs block dopamine activity so minimising the
             effects of dopamine, while others also act on serotonin uptake.
           • A patient can take the anti-psychotic medication in syrup or tablet form
             allowing them to select different methods of treatment.
           • If patients forget to take them then medical practitioners could inject the
             anti-psychotic drugs to help with drug compliance.
           AO3
           • Phenothiazine drugs block dopamine receptors and are effective as
             patients who respond to these show signs of improvement, with a
             reduction in most schizophrenic symptoms.
           • Bustillo et al. (2001) found that Assertive Community Treatments (ACT)
             help with preventing psychotic relapse and hospitalisation, so drug
             therapy targeting neurotransmitters can be combined with other
             interventions to achieve an overall more successful treatment.
           • Adityanjee and Kaizad (2005) found that in 0.05% of patients, anti-
             psychotic drugs lead to neuroleptic malignant syndrome which causes
             nausea, high blood pressure, confusion, and in 10% of cases, death, so
             despite effectiveness there may be negative health implications.
           • Eaton (1980) found that schizophrenia is associated with city life rather
             than biological factors, so if schizophrenia is related to the environment
             and social adversity it may be that drug therapy is ineffective.
           • Anti-psychotics can reduce symptoms of schizophrenia more rapidly than
             therapies such as family therapy, so can reduce patient distress quickly
             increasing the effectiveness of drugs as a treatment.
           • Meltzer et al. (2004) found patients using haloperidol had reduced
             symptoms of schizophrenia and showed improvements in day to day
             functioning, so the treatment is effective.
           • Emsley (2008) found that risperidone injections reduced both positive and
             negative symptoms of schizophrenia, with 64% of patients having no
             symptoms two years on, highlighting that drug therapy can be an
             effective treatment for a range of schizophrenia symptoms.
           • Drug therapy is reductionist as it only considers neurotransmitters as a
             cause of schizophrenia, yet an alternative biological explanation suggests
             genetics play a role in schizophrenia, so drugs would be ineffective.
           •   Rosa et al. (2005) found only 50% of patients complied with taking
               their anti-psychotics, so while they may be successful in terms of
               the impact on neurotransmitters, they are ineffective if drug
               compliance is low.
           •   Hartling et al. (2012) reviewed 114 studies and found it difficult to
               reach overall conclusions of antipsychotic effectiveness due to
               possible bias, brief follow-up trials, and use of selective
               populations.

                  her research to be a reliable test of testosterone and aggression
                  (1), this ensures she meets the requirement of ‘reduction’ in the
                  Animals (Scientific Procedures) Act 1986 that the number of
                  animals is reduced to the minimum needed to achieve the results
                  sought (1).
              •   The medical procedure on the rats should be undertaken in a

                  operation and afterwards during the experiment (1). This is

               stimulation of dopamine to reach their desired mood, so

               poor social life could be addressed through interventions like
               family therapy where the concerns about the inability to control
               internet use can be discussed to support the internet addict to
               stop.
             • SSRI’s may help reduce the withdrawal symptoms from not
               using the internet which may be due to the addict needing
               greater amounts of time online to achieve the same emotional
               response and mood that they desire from the use of mobile
               devices or video games.

           • Milgram’s (1963) research into obedience has increased our understanding of
             the situations in which blind, destructive obedience is most likely to happen.
           • The working memory model provides an understanding of processing speeds
             and phonological development in active short-term memory functioning.
           • Bartlett’s (1932) theory of reconstructive memory helps to understand why
             memory can be inaccurate and recall of events may be different to the exact
             experience.
           • The role of brain functioning and structures in aggression, such as the pre-
             frontal cortex or amygdala, provides knowledge of the innate factors involved
             in aggression.
           • Social learning theory emphasises the importance of the role model in the
             learning of behaviour through attention, retention, reproduction, and
             motivation.
           • Explanations of behaviours as a result of hormones have been able to explain
             how human behaviour can be due to imbalanced melatonin or testosterone.
           • Bowlby’s (1944) research of 44 juvenile thieves suggested that the lack of a
             maternal attachment figure could result in children developing affectionless
             psychopathy.
           • Classical conditioning claims that behaviours such as phobic responses are the
             product of stimulus-response pairing and association.

           • Knowing the factors that impact on obedience can help society with prevention
             strategies to reduce atrocities such as the Mai Lai massacre from happening
             again.
           • Understanding of the optimum conditions for obedience to an authority figure
             could be used negatively in society by individuals seeking to influence others
             and gain power and control over those in subordinate positions to them.
           • Using knowledge of working memory can help children with dyslexia access
             learning through classroom strategies and direct interventions such as Cog-
             Med that improve working memory functioning and the accessibility of
             educational content.
           • Memory has been found to be largely accurate in eyewitness testimony by
             Yuille and Cutshall (1986) so considering eyewitness accounts as inaccurate in
             court trials could be detrimental to achieving justice for defendant or victims of
             criminal activities.
           • Raine et al. (1997) found that murderers pleading not guilty by reason of
             insanity had less activity in their prefrontal brain regions and corpus callosum,
             helping criminal justice systems understand that violence may not always be a
             rational choice.
           • Despite awareness in society of negative influences of thin women in the
             media on eating disordered behaviour, such as Becker et al. (2002) society
             does not always use this information to reduce negative influencers, so thin
             role models remain available.
           • Bandura’s research in his Bobo Doll studies has been utilised in society to
             reduce access to violent or aggressive media sources by children, such as the
             PEGI game ratings on video games and the age ratings for movies.
           • Aggression has been linked to testosterone which has led to chemical
             treatments for violent male offenders, however this does not explain violence
             in females and can only be partially used in society to treat offenders.
           • Treatments such as light therapy have proved to be effective use of our
             knowledge of the interactions between hormones and external zeitgebers to
             help treat patients with seasonal affective disorder and irregular sleep patterns
             or disorders.
              •   While effective parenting is an important use of psychological knowledge, the
                  findings of Bowlby (1944) may result in society placing blame on the mothers
                  of children who demonstrate anti-social behaviours, which results in negative
                  attitudes to the mother.
              •   Systematic desensitisation has developed from the understanding of phobia
                  acquisition to provide an effective treatment for patients with phobias, shown
                  by Capafons (1998) in their treatment of a fear of flying.
              •   Aversion therapy for homosexuality has been used to ‘cure’ people of their
                  sexual attractions, despite homosexuality being removed from the DSM in
                  1973, so the misuse of therapies can lead to social control over the lifestyles of
                  people.
