2. Understanding the Marking Criteria | 理解评分标准

Edexcel uses a levels-based mark scheme for extended writing. For the 20-mark essay, examiners look for depth and range of material, accurate terminology, well-developed arguments, and a concluding judgement that weighs competing evidence. Avoid simply listing strengths and limitations; instead, build ‘chain of reasoning’ paragraphs that link evidence back to the question stem.

Edexcel 对长篇写作采用层级评分制。在 20 分论文中，考官看重材料的深度与广度、术语准确性、论证的充分展开，以及能够权衡对立证据的总结性判断。切忌只是罗列优缺点；要构建“推理链条”式段落，将证据始终扣回题目主干。

3. Question Walkthrough: Describing Symptoms | 题目解析：描述症状 (4 marks)

Question 1: ‘Describe two positive symptoms of schizophrenia.’ (4 marks) The command word ‘describe’ requires accurate, detailed features. A full-mark response identifies two symptoms, e.g., hallucinations and delusions, and elaborates on each with an example or a precise operational definition. For hallucinations, specify modality (auditory) and give a real-world manifestation, such as hearing a voice commenting on one’s actions.

第1题：“描述精神分裂症的两种阳性症状。”（4分） 指令词“描述”要求准确且详尽的特征。满分答案需明确指出两种症状，例如幻觉和妄想，并对每一种加以阐释，给出实例或精确的操作性定义。关于幻觉，要说明感觉通道（听觉）并呈现真实表现，比如听见有声音在评论自己的行为。

A strong 4-mark answer would state: ‘One positive symptom is auditory hallucinations, where the individual perceives sounds or voices without external stimuli, often hearing a running commentary on their behaviour. A second is persecutory delusions, which are firmly held false beliefs that others intend to harm them, such as the conviction that the government is monitoring their thoughts.’ This hits the top band because it goes beyond a single-word label.

一份出色的 4 分答案会写道：“一种阳性症状是幻听，即个体在无外部刺激时感知到声音或话语，常常听到对自己行为进行的实时评论。第二种是被害妄想，这是一种顽固坚持的错误信念，认为他人意图伤害自己，比如坚信政府在监控自己的思想。”这之所以达到最高等级，是因为它超越了一个词标签。

4. Question Walkthrough: Twin Studies & Schizophrenia | 题目解析：双胞胎研究在精神分裂症中的应用 (6 marks)

Question 2: ‘Explain how twin studies support a genetic explanation of schizophrenia.’ (6 marks) This requires two strands: explaining the logic of concordance rates and linking actual research evidence to the argument. Begin by outlining that monozygotic (MZ) twins share 100% of their genes, while dizygotic (DZ) twins share about 50%. Higher concordance in MZ twins suggests a genetic component.

第2题：“解释双胞胎研究如何支持精神分裂症的遗传学解释。”（6分） 这需要两条线索：解释一致率的逻辑，并将实际研究证据与论证关联。先陈述同卵（MZ）双胞胎共享 100% 的基因，而异卵（DZ）双胞胎共享约 50% 的基因。MZ 双胞胎具有更高的一致率暗示了遗传成分。

Always quote key figures. For instance, Gottesman (1991) found a 48% concordance rate for MZ twins compared to 17% for DZ twins. Then critically apply: ‘Because MZ concordance is not 100%, genetics cannot be the sole cause; environmental triggers must also play a role. This qualifies the explanation rather than undermining it.’ A 6-mark answer must show this refined understanding.

务必引用关键数据。例如，Gottesman（1991）发现 MZ 双胞胎的一致率为 48%，而 DZ 仅 17%。随后批判性应用：“由于 MZ 一致率并非 100%，遗传并非唯一原因；环境触发因素必然也发挥作用。这限定了这一解释而非否定它。”一道 6 分答案必须展现这种精炼的理解。

5. Question Walkthrough: Evaluating Drug Therapy | 题目解析：评价药物治疗 (12 marks)

Question 3: ‘Evaluate the use of antipsychotic medication as a treatment for schizophrenia.’ (12 marks) An effective 12-mark evaluation balances biological effectiveness with practical and ethical considerations. You should present a point, evidence, and a balanced comment for each paragraph — never a one-sided list. Structure three detailed paragraphs: efficacy, side-effects and the ‘revolving door’ problem, and comparison with psychological therapies.

第3题：“评价抗精神病药物作为精神分裂症的治疗方法。”（12分） 有效的 12 分评价需要在生物有效性、现实考虑和伦理关切之间取得平衡。每一个段落都要展现观点、证据和平衡性评论——切忌一面之词地罗列。构建三个详细段落：疗效、副作用与“旋转门”问题、以及与心理治疗的比较。

For efficacy, cite meta-analyses showing typical antipsychotics reduce positive symptoms in about 60% of patients, but note the non-responder group and the fact that negative symptoms remain largely unaddressed. For side-effects, discuss tardive dyskinesia and weight gain with atypicals, which can lead to non-adherence. Link to the diathesis-stress model: medication manages biological vulnerability but leaves psychosocial stressors untouched, which is why family therapy often boosts outcomes. Such integration demonstrates synoptic thinking.

关于疗效，可引用元分析表明典型抗精神病药大约 60% 的患者阳性症状减轻，但要指出无反应者群体以及阴性症状几乎未被解决。关于副作用，讨论迟发性运动障碍和非典型药物的体重增加，这可能导致不依从。联系素质-应激模型：药物控制生物脆弱性，但对社会心理应激源束手无策，这正是为何家庭治疗常能提升疗效。这种整合体现了通观思维。

6. Question Walkthrough: CBT for Depression | 题目解析：认知行为疗法治疗抑郁症 (20 marks)

Question 4: ‘Discuss cognitive behavioural therapy (CBT) as a treatment for depression.’ (20 marks) The 20-mark essay demands a clear introduction, AO1 outlining the cognitive model and CBT techniques, and substantial AO3 weaving together research evidence, comparison with drug therapy, and effectiveness for different subgroups. A top essay structures AO1 and AO3 seamlessly within each paragraph rather than separating them into two large blocks.

第4题：“讨论认知行为疗法（CBT）作为抑郁症的治疗方法。”（20分） 20 分论文要求清晰的引言、概述认知模型和 CBT 技术的 AO1 部分，以及充足的 AO3 部分，将研究证据、与药物疗法的比较、以及针对不同亚群体的有效性交织论述。高分论文会在每个段落内将 AO1 和 AO3 无缝结合，而非将其分成两大块。

AO1 should succinctly describe Beck’s negative triad and Ellis’s ABC model, then specify core techniques: cognitive restructuring, behavioural activation, thought records. Transition into AO3 by stating that Wiles et al. (2013) showed CBT plus usual care halved treatment-resistant depression compared to usual care alone. Then critically note that this was a randomised controlled trial on a Western sample, raising cultural validity questions. A separate paragraph can compare with SSRIs: CBT has lower relapse rates at 12-month follow-up because it equips patients with skills, yet it requires high motivation and verbal fluency, which acute depression may impair. Conclude with a synthesised judgement: CBT is particularly effective for mild-to-moderate depression and when combined with medication for severe cases, reflecting holistic practice.

AO1 应简洁描述 Beck 的负性三联征和 Ellis 的 ABC 模型，然后具体说明核心技术：认知重构、行为激活、思维记录。转向 AO3 时可陈述 Wiles 等人（2013）发现 CBT 加常规护理使难治性抑郁的缓解率比单纯常规护理提高一倍。接着批判性指出，这是一项在西方样本上进行的随机对照试验，存在文化效度疑问。另一个段落可与 SSRIs 比较：CBT 在 12 个月随访时复发率更低，因为它赋予患者技能，但它要求较高的动机和语言流畅性，而重度抑郁可能削弱这些能力。以综合判断结尾：CBT 对轻中度抑郁尤其有效，与药物联合用于重度病例效果最佳，这反映了整体实践。

7. Question Walkthrough: Research Methods Application | 题目解析：研究方法应用 (8 marks)

Question 5: ‘Design an observation to investigate adherence to a CBT homework programme in teenagers with depression.’ (8 marks) This research-methods item tests procedural precision. You must specify: type of observation (e.g., structured, participant), sampling method (opportunity from a clinical sample), operationalised behavioural categories (completing thought diary, attendance, latency to submit), inter-rater reliability checks, and one ethical safeguard (informed consent from guardians). Edexcel rewards practical feasibility over ambition.

第5题：“设计一项观察研究，考察抑郁症青少年对 CBT 家庭作业计划的依从性。”（8分） 这一研究方法题考查程序精确性。必须写明：观察类型（如结构化、参与式）、取样方法（从临床样本中机遇取样）、操作化的行为类别（完成思维日记、出勤、提交延迟时间）、评分者间信度检验，以及一项伦理保护（获得监护人知情同意）。Edexcel 看重的是切实可行，而非天马行空的野心。

A model answer includes: ‘We will use a structured non-participant observation, with two trained observers independently coding 10-minute video recordings of group check-in sessions. Behavioural categories: (A) brings completed diary — yes/no; (B) contributes at least one verbal reflection. Inter-rater reliability will be calculated using Cohen’s kappa, with a threshold of κ > 0.80.’ This displays methodological rigour without overcomplicating.

标准答案包括：“我们将采用结构化非参与式观察，由两名经过训练的观察员对 10 分钟小组检查会议录像进行独立编码。行为类别：(A) 携带完成的日记——是/否；(B) 至少做出口头反思一次。评分者间信度采用 Cohen’s kappa 计算，阈值为 κ > 0.80。”这展现方法学严谨性而不过度复杂。

8. Common Pitfalls and Examiner Advice | 常见错误与考官建议

A recurring weakness is offering an undeveloped list of strengths and weaknesses. Instead, use the PEEL structure: Point, Evidence/Example, Explain, and Link back. When evaluating, always consider ‘For whom?’ and ‘Under what conditions?’ — for instance, drug therapy may be more feasible for acute inpatient settings, while CBT suits motivated outpatients. Another pitfall is using outdated terminology, such as ‘manic depression’ instead of bipolar disorder.

一个反复出现的弱点是提供未经展开的优缺点罗列。改用 PEEL 结构：观点、证据/示例、解释、回链题目。在评价时，始终考虑“对谁而言？”以及“在何种条件下？”——例如，药物治疗对急性住院环境也许更可行，而 CBT 适合有动机的门诊患者。另一个陷阱是使用过时术语，如用“躁狂抑郁症”而非双相障碍。

Examiners also emphasise that AO3 points must be rooted in psychological research, not just common sense. Saying ‘therapy is time-consuming’ lacks credit unless you link it to attrition rates from a specific trial, such as a study where 40% of participants dropped out of a 16-week CBT programme. Precision with data transforms generic comments into exam-worthy evaluation.

考官还强调，AO3 论点必须扎根于心理学研究，而非仅仅常识。说“疗法耗时长”缺乏分数，除非你将它与某特定试验的流失率关联，比如一项研究显示 40% 的参与者中途退出了 16 周的 CBT 项目。用数据支撑的精确性能将泛泛评论变成符合考试要求的评价。

9. Revision Strategies for Unit Tests | 单元测试复习策略

Active revision should move beyond rereading notes. Create mind maps linking a disorder (e.g., schizophrenia) to its explanations, treatments, and key studies, then practise writing timed paragraphs connecting two of these areas. For example, ‘Explain how the dopamine hypothesis has influenced the development of atypical antipsychotics.’ Such links are exactly what high-mark questions require.

主动复习应超越重读笔记。绘制思维导图将某一障碍（如精神分裂症）与其解释、治疗和关键研究关联，然后进行定时写作练习，将其中两个领域联系起来。例如，“解释多巴胺假说如何影响了非典型抗精神病药的发展。”这种联系正是高分题目所要求的。

Use past mark schemes to internalise the depth expected. Keep a ‘command word glossary’: ‘Describe’ means give details of; ‘Evaluate’ means weigh strengths against limitations and reach a conclusion; ‘Discuss’ expects an exploration of multiple viewpoints. Finally, simulate test conditions by completing a full mock under timed pressure, then self-assess with the marking criteria we analysed earlier.

利用历年评分方案，内化所要求的深度。准备一份“指令词词典”：“描述”意味着给出细节；“评价”意味着权衡优缺点并得出结论；“讨论”期待探索多种视角。最后，在限时压力下完成全套模拟，并运用我们前文分析的评分标准进行自我评估，以真实模拟考试情境。
