1. Q1: Defining Abnormality | 题目1：定义异常行为
Question: Outline one definition of abnormality. [2 marks]
题目：概述一种异常行为的定义。[2分]
A precise answer would be the deviation from social norms definition: behaviour that breaks implicit or explicit rules of a society is regarded as abnormal. One mark is awarded for naming the definition and one mark for a brief, accurate elaboration.
一个精确的答案可以是偏离社会规范的定义：违反某一社会明示或暗示规则的行为被视为异常。指出定义得1分，给出简洁准确的阐述再得1分。
Many candidates lose a mark by simply writing 'deviation from social norms' without explaining what that means. A single extra sentence such as 'social norms vary across cultures and eras, so the same behaviour may be judged differently' is enough to secure the second mark.
许多考生因仅仅写出"偏离社会规范"而丢分，完全没有解释其含义。额外加一句，比如"社会规范随文化和时代而变化，因此同一行为可能被不同地评判"，就足以拿到第二分。
Examiners also accept 'failure to function adequately', 'deviation from ideal mental health' or 'statistical infrequency', provided the definition is clearly linked to one named concept.
考官也接受"无法充分应对生活""偏离理想心理健康"或"统计稀有性"，前提是将定义清晰地联系到某一个指定的概念。
2. Q2: Biological Explanation for OCD | 题目2：强迫症的生物学解释
Question: Explain one biological explanation for OCD. [4 marks]
题目：解释强迫症的一种生物学解释。[4分]
The candidate could focus on the neurotransmitter explanation. For full marks, they need to identify serotonin as the key neurotransmitter, state that low levels of serotonin are linked to OCD, and briefly describe the mechanism (e.g., serotonin normally helps regulate mood and inhibit repetitive behaviours; when levels are low, the orbitofrontal cortex and basal ganglia may become overactive, leading to obsessive thoughts and compulsive rituals). Two marks for outlining the explanation and two marks for developing it with some supporting detail.
考生可以聚焦于神经递质解释。要拿满分，需要指出血清素是关键神经递质，表明低水平血清素与强迫症有关，并简要描述机制（例如，血清素通常帮助调节情绪和抑制重复行为；当水平偏低时，眶额皮层和基底神经节可能过度活跃，从而导致强迫思维和强迫行为）。概述解释得2分，用一些支持性细节展开再得2分。
A common mistake is to generically state 'low serotonin causes OCD' without linking the neurotransmitter to specific brain circuits. To strengthen the response, candidates can add that SSRIs alleviate symptoms by increasing serotonin availability in the synapse, which is consistent with the explanation.
一个常见错误是笼统地说"低血清素引起强迫症"，却没有将神经递质与特定的脑回路联系起来。为了让回答更有力，考生可以补充SSRIs通过增加突触中血清素的可利用性来缓解症状，这与该解释一致。
An alternative acceptable explanation is the genetic explanation, where candidates can refer to twin studies (e.g., higher concordance in MZ than DZ twins) or specific genes such as the SERT gene. Again, marks are for both identification and elaboration.
另一种可接受的解释是遗传解释，考生可以提及双生子研究（例如，同卵双生子的同病率高于异卵双生子）或特定基因如SERT基因。同样，得分点在于识别和阐述。
3. Q3: Diathesis-Stress Model and Schizophrenia | 题目3：素质-应激模型与精神分裂症
Question: Describe the diathesis-stress model in explaining schizophrenia. [6 marks]
题目：描述素质-应激模型如何解释精神分裂症。[6分]
The diathesis-stress model proposes that schizophrenia develops through the interaction of a pre-existing vulnerability (diathesis) and environmental stressors. The diathesis is often biological, such as a genetic predisposition (e.g., candidate genes like DISC1) or early brain damage, and the stressor can be psychological or social, such as childhood trauma, urban upbringing or substance abuse. A high diathesis requires only a mild stressor, while a low diathesis requires a severe stressor to trigger the disorder.
素质-应激模型认为，精神分裂症通过已有的易感性（素质）和环境应激源之间的交互作用而产生。素质通常是生物性的，比如遗传易感性（例如候选基因如DISC1）或早期脑损伤；应激源可以是心理或社会的，如童年创伤、城市成长环境或物质滥用。高素质只需轻微应激源即可触发，低素质则需要严重应激源才能诱发障碍。
To access all six marks, candidates should present the model as an interactionist framework, provide at least one concrete example of a diathesis and one of a stressor, and explicitly state that neither factor alone is sufficient. A well-structured paragraph that moves from definition to specific research evidence (e.g., Tienari et al.'s Finnish adoption study) will reach the top band.
要拿到全部6分，考生应将模型呈现为一个交互作用框架，至少提供一个素质的具体例子和一个应激源的具体例子，并明确说明单独任一因素都不足以致病。一段组织良好的文字，从定义过渡到具体研究证据（如Tienari等人的芬兰收养研究），就能进入最高评分段。
Weak responses often describe diathesis and stress separately without showing how they combine, or they confuse the diathesis-stress model with a purely biological or purely psychological model.
较弱的回答常常分别描述素质和应激，却不展示它们如何结合，或者将素质-应激模型与纯粹的生物学模型或心理模型混为一谈。
4. Q4: Evaluating Token Economy Programmes | 题目4：评价代币经济方案
Question: Evaluate the use of token economy programmes in managing schizophrenia. [8 marks]
题目：评价代币经济方案在管理精神分裂症中的使用。[8分]
For the AO1 (description) marks, candidates should outline that token economies are based on operant conditioning: patients receive tokens (secondary reinforcers) for performing target behaviours (e.g., self-care, social interaction), which can be exchanged for primary reinforcers like snacks or privileges. For AO3 (evaluation), a balanced discussion should include effectiveness evidence, practical strengths and limitations, and ethical considerations.
对于描述分（AO1），考生应概述代币经济基于操作条件反射：患者因表现出目标行为（如自我照顾、社交互动）而获得代币（次级强化物），代币可兑换初级强化物，如零食或特权。对于评价分（AO3），平衡的讨论应包括有效性证据、实际优点和局限性以及伦理考量。
Strengths that can be credited: research by Paul and Lentz (1977) showed token economies improved social functioning and reduced negative symptoms in long-stay wards; they are relatively easy to implement by nursing staff. Weaknesses: the gains often do not generalise outside the institution; some critics argue it is ethically questionable to control basic rewards for vulnerable patients; and with the move towards community care, token economies have become less widely used.
可得分优点：Paul and Lentz (1977) 的研究表明代币经济改善了长期病房的社会功能并减轻阴性症状；它们相对容易由护理人员实施。缺点：成效通常无法泛化到院外；一些批评者认为控制弱势患者的基本奖励存在伦理争议；随着向社区照护的转变，代币经济的使用已不那么广泛。
Top-band answers go beyond a list of strengths and weaknesses, making a judgement such as 'token economies are effective as part of a wider multimodal approach but insufficient alone'. The essay must remain focused on schizophrenia, not just behaviour modification in general.
高分段回答会超越优缺点列表，做出判断，例如"代币经济作为更广泛多模式方法的一部分是有效的，但单独使用则不足"。论述必须紧扣精神分裂症，而非笼统的行为矫正。
5. Q5: Case Study Research on Agoraphobia | 题目5：广场恐惧症案例研究
Question: A psychologist conducted a case study of a patient with agoraphobia. Describe one strength and one weakness of using case studies in this context. [6 marks]
题目：一位心理学家对一名广场恐惧症患者进行了案例研究。描述在此背景下使用案例研究的一个优点和一个缺点。[6分]
For the strength, a candidate might explain that case studies generate rich, in-depth data about the individual's personal experience, triggers and coping strategies, which can reveal patterns overlooked by group-based studies. This idiographic approach can inform future hypotheses and treatment plans. For the weakness, a common point is that findings from a single individual cannot be generalised to the wider population of agoraphobia sufferers because the patient's characteristics, background and symptoms are unique.
对于优点，考生可以解释案例研究能生成关于个体亲身经历、诱因和应对策略的丰富深入数据，这能揭示群体研究可能忽略的模式。这种个案研究法可为未来假设和治疗方案提供信息。对于缺点，常见的观点是来自单一个体的发现无法推广到更广泛的广场恐惧症患者群体，因为患者的特点、背景和症状都是独特的。
Three marks are available for each well-developed point. A simple statement like 'it gives detailed data' is not enough for three marks; candidates should link the point directly to agoraphobia (e.g., 'details about how the patient avoids public transport can inform a personalised exposure hierarchy').
每个充分展开的要点可得3分。像"它能提供详细数据"这样简单的陈述不足以拿3分；考生应将要点直接联系到广场恐惧症（例如，"关于患者如何避开公共交通的细节能为个性化暴露等级提供信息"）。
Other acceptable weaknesses include lack of replicability, researcher bias because of the close relationship with the participant, and difficulty establishing cause and effect. The question explicitly asks for 'one strength and one weakness', so writing more than one of each does not attract extra marks and may waste valuable time.
其他可接受的缺点包括缺乏可重复性、由于与参与者关系密切而产生的研究者偏见，以及难以建立因果关系。问题明确要求"一个优点和一个缺点"，因此多写并不加分，反而可能浪费宝贵时间。
6. Q6: Ethical Issues in Schizophrenia Research | 题目6：精神分裂症研究中的伦理问题
Question: Discuss ethical issues involved in research with patients diagnosed with schizophrenia. [6 marks]
题目：讨论涉及精神分裂症患者的研究中的伦理问题。[6分]
Several ethical issues are relevant. Informed consent can be compromised if patients are experiencing acute psychotic symptoms that impair their ability to understand the research. Researchers must ensure participants have the capacity to consent and, where needed, obtain proxy consent from a legally authorised representative. Protection from psychological harm is crucial because the nature of questioning about delusions or hallucinations may cause distress or exacerbate paranoid thoughts.
多个伦理问题与此相关。知情同意可能受损，如果患者正经历急性精神病性症状，削弱其理解研究的能力。研究者必须确保参与者具备同意能力，并在必要时从法定授权代表处获得代理同意。保护免受心理伤害至关重要，因为关于妄想或幻觉的询问性质可能引起痛苦或加剧偏执想法。
Confidentiality can be particularly sensitive: a breach of a schizophrenia diagnosis could lead to stigmatisation in employment or personal relationships. Researchers must anonymise data and store it securely. Additionally, the right to withdraw should be clearly communicated, but a patient in a disturbed state may not remember this right; researchers have an ongoing duty to monitor the participant's willingness to continue.
保密性可能特别敏感：泄漏精神分裂症诊断可能导致就业或人际关系中的污名化。研究者必须匿名化数据并安全存储。此外，退出权利应被清晰传达，但处于紊乱状态的患者可能不记得这项权利；研究者有持续责任监测参与者继续参与的意愿。
To achieve high marks, candidates must not simply list the BPS ethical guidelines but apply them to the specific challenges of schizophrenia research. Linking to a named study (e.g., any drug trial where placebo groups may experience relapse) strengthens the discussion.
要获得高分，考生不应仅仅列出BPS伦理准则，而应将其应用于精神分裂症研究的具体挑战。联系到一项署名研究（如任何安慰剂组可能出现复发的药物试验）能强化讨论。
7. Q7: Rosenhan (1973) and Diagnostic Reliability | 题目7：Rosenhan (1973) 与诊断信度
Question: Referring to the study by Rosenhan (1973), explain what it shows about the reliability of diagnosis. [4 marks]
题目：参考Rosenhan (1973) 的研究，解释它显示了诊断信度的什么问题。[4分]
Rosenhan's 'Being Sane in Insane Places' study revealed serious problems with the reliability of psychiatric diagnosis. Eight pseudo-patients presented themselves to hospitals claiming to hear a voice saying 'thud', 'empty' or 'hollow'. All were admitted and diagnosed with schizophrenia (except one with bipolar disorder). Despite behaving normally once on the ward, their normal behaviours were often interpreted as pathological (e.g., note-taking was labelled 'writing behaviour'). This demonstrates a lack of validity, but the study is frequently used to argue that diagnostic reliability is low because clinicians could not distinguish the sane from the insane.
Rosenhan 的"当正常人在不正常的地方"研究揭示了精神科诊断信度的严重问题。八名假病人前往医院，声称听到"砰""空"或"空洞"的声音。所有人均被收治并被诊断为精神分裂症（一人为双相障碍）。尽管进入病房后行为正常，他们的正常行为常被解释为病态（如记笔记被标记为"书写行为"）。这表明缺乏效度，但该研究常被用来论证诊断信度低下，因为临床医生无法区分正常人与精神病人。
For full marks, candidates need to explicitly state that the study highlights the lack of inter-rater reliability in real clinical settings and link this to the consequences of diagnostic labels. A brief mention of the follow-up study, where hospitals were warned but still identified fake patients who did not exist, can further illustrate the point.
要拿到满分，考生需要明确指出该研究凸显了真实临床环境中评分者间信度的缺乏，并将其与诊断标签的后果相联系。简要提及后续研究——医院虽收到警告但仍识别出不存在的假病人——能进一步说明问题。
8. Q8: Essay – Biological Treatments for Mental Disorders | 题目8：论文题——心理障碍的生物治疗
Question: 'Biological treatments are the most effective way of treating mental disorders.' Discuss with reference to at least two disorders. [12 marks]
题目："生物治疗是治疗心理障碍最有效的方式。"参考至少两种障碍进行讨论。[12分]
For this 12-mark essay, a strong structure is essential. AO1 (4 marks) should outline two biological treatments, for example drug therapy for schizophrenia (typical and atypical antipsychotics) and SSRIs for depression. AO2 (4 marks) must apply the argument to the named disorders, such as explaining how antipsychotics reduce dopamine activity and thereby alleviate positive symptoms, while SSRIs raise serotonin levels to improve mood. AO3 (4 marks) requires evaluation: effectiveness evidence (e.g., meta-analyses showing superiority over placebo), side effects (e.g., tardive dyskinesia, weight gain), the role of the therapeutic alliance in drug adherence, and the argument that biological treatments ignore psychological and social factors, often needing to be combined with CBT or family therapy.
对于这道12分论文题，清晰的结构至关重要。AO1（4分）应概述两种生物治疗，例如针对精神分裂症的药物治疗（经典和非经典抗精神病药）和针对抑郁症的SSRIs。AO2（4分）必须将论证应用于指定的障碍，比如解释抗精神病药如何降低多巴胺活性从而缓解阳性症状，而SSRIs如何提升血清素水平以改善情绪。AO3（4分）需要评价：有效性证据（如荟萃分析显示优于安慰剂）、副作用（如迟发性运动障碍、体重增加）、治疗关系在药物依从性中的作用，以及生物治疗忽视心理和社会因素，常需与CBT或家庭治疗结合的观点。
A top-level response will reach a balanced conclusion, such as 'Biological treatments are highly effective for symptom reduction, especially in severe cases, but their long-term success often depends on integration with psychological interventions and consideration of individual differences.'
一份顶尖水平的回答将得出平衡的结论，例如"生物治疗在减轻症状方面非常有效，尤其在严重案例中，但其长期成功往往依赖于与心理干预的整合以及对个体差异的考量。"
Common mistakes include discussing only one disorder, failing to provide a clear chain of reasoning, or simply describing treatments without evaluating their relative effectiveness. Planning before writing is highly recommended.
常见错误包括只讨论一种障碍、未能提供清晰的推理链，或者仅仅是描述治疗而不评价其相对有效性。强烈建议动笔前先做计划。
9. Exam Technique: Boosting Your Grade | 题目9：考试技巧：提升你的分数
Across all questions, examiners look for precision, use of psychological terminology, and clear structure. Always check the command word: 'outline' demands a concise account, 'describe' requires detail, and 'evaluate' or 'discuss' calls for both strengths and weaknesses with concluding judgement.
在所有题目中，考官都看重精确性、心理学专业术语的使用以及清晰的结构。务必注意指令词："outline"要求简明陈述，"describe"需要细节，"evaluate"或"discuss"则要求优缺点兼具并给出总结性评判。
Time management is critical. Allocate roughly one minute per mark: a 2-mark question deserves about two minutes, while a 12-mark essay should take around 12–14 minutes. Leave a few minutes at the end to check for missing details or misread questions.
时间管理至关重要。大致按每分钟1分来分配：2分的题用2分钟左右，12分的论文题应用12–14分钟。留出最后几分钟检查是否有遗漏细节或误读题目。
In Abnormal Psychology, always link your evaluation points back to the specific diagnosis. Generic statements about 'individual differences' or 'cultural bias' gain credit only when applied to schizophrenia, OCD, agoraphobia or whichever disorder is in the question. And never forget that the Rosenhan study is a classic: knowing it thoroughly can help you answer questions on diagnosis, reliability, ethics and the harmful effects of labelling.
在异常心理学中，务必将你的评价要点与具体诊断联系回来。关于"个体差异"或"文化偏见"的泛泛陈述只有在被应用到精神分裂症、强迫症、广场恐惧症或题目所指的任何障碍时才能得分。永远别忘了Rosenhan 研究是经典：透彻掌握它能助你回答关于诊断、信度、伦理及标签伤害性影响的问题。
