Key command words include 'identify', 'explain', 'suggest', and 'evaluate'.
模拟卷包含 10 道必答题，融合了简答题、情境题和一篇扩展论文。总分设计参考标准的 90 分试卷，题目从简单的识别逐步过渡到高阶的评价。重要的指令词包括“识别”、“解释”、“建议”和“评价”。
Each question targets one or more assessment objectives: AO1 (recall knowledge), AO2 (application and analysis), and AO3 (evaluation). The analysis that follows highlights how to meet these objectives efficiently, allowing you to self-assess and build confidence.
每道题针对一个或多个评估目标：AO1（知识回忆）、AO2（应用与分析）和 AO3（评价）。随后的解析将强调如何高效达成这些目标，帮助你进行自我评估并树立信心。
2. Question 1: Identifying Variables | 题目 1：识别变量
A researcher wants to test whether listening to classical music during revision improves examination scores. Fifty students are randomly allocated to revise with classical background music or in silence. After a one-hour revision session, all students sit the same test. The scores are compared. (a) Identify the independent variable (IV) and the dependent variable (DV). (b) Suggest one possible extraneous variable and explain how it could be controlled.
一位研究者想测试在复习时听古典音乐是否能提高考试成绩。50 名学生被随机分配在有古典背景音乐或安静环境中复习。经过一小时的复习，所有学生参加相同的测验。比较测验分数。(a) 识别自变量 (IV) 和因变量 (DV)。(b) 提出一个可能的额外变量并解释如何加以控制。
Analysis: The IV is the presence or absence of classical music (the condition under which participants revise). The DV is the test score (numerical performance). An extraneous variable exemplar is participants' prior knowledge of the subject; this could be controlled by using a pre-test to ensure groups have equivalent baseline scores, or by random allocation to distribute individual differences evenly.
解析：自变量是古典音乐的存在与否（参与者复习时所处的条件）。因变量是测验分数（数值表现）。额外变量的一个例子是参与者对该科目的先前知识；这可以通过前测来确保组间基线水平相当，或通过随机分配来均匀分布个体差异。
When writing answers, always operationalise variables clearly. State 'the IV is whether music is played or not' rather than just 'music'. The DV should be measurable: 'score on a 30-question test'.
作答时，务必清晰地操作化变量。表述为“自变量是是否播放音乐”而不仅仅是“音乐”。因变量应当可测量：“在 30 题测验中的得分”。
3. Question 2: Experimental Design | 题目 2：实验设计
A psychologist compared two teaching methods by having one class of 20 students learn algebra with Method A and another class of 20 learn with Method B. After four weeks, all students took the same maths test. (a) Identify the experimental design used. (b) Explain one strength and one weakness of this design in the context of the study.
一位心理学家比较了两种教学方法，让一个 20 人的班级用方法 A 学习代数，另一个 20 人的班级用方法 B 学习。四周后，所有学生参加相同的数学测验。(a) 指出该研究使用的实验设计。(b) 结合该研究解释该设计的一个优点和一个缺点。
Answer and guidance: The design is an independent groups design (or independent measures), because different participants are used in each condition. A strength is that there are no order effects (e.g., practice or fatigue) since participants are tested only once. A weakness is that individual differences between the two classes (e.g., ability, motivation) could act as confounding variables, reducing internal validity. The researcher cannot be sure the differences in test scores are due to the teaching method alone.
答案与指导：该设计为独立组设计（或独立测量），因为每种条件下使用了不同的参与者。优点是不会有顺序效应（如练习或疲劳），因为参与者只接受一次测试。缺点是两组之间的个体差异（如能力、动机）可能成为混淆变量，降低内部效度。研究者无法确信测验分数的差异仅由教学方法导致。
An alternative design like a matched pairs approach would have compared students matched on prior maths grades, but this was not implemented. In exams, always link the strength and weakness precisely to the scenario.
另一种设计如配对组设计会按之前的数学成绩匹配学生后再比较，但在此未采用。在考试中，务必将优点和缺点与情境精确关联。
4. Question 3: Sampling Methods | 题目 3：抽样方法
A market research company wants to investigate teenagers’ attitudes towards social media use. An interviewer approaches every tenth person entering a shopping mall and asks them to complete a questionnaire. (a) Name the sampling method. (b) Discuss one advantage and one disadvantage of this sampling method for the study.
一家市场调研公司想调查青少年对社交媒体使用的态度。一名访问员走近每第十个进入购物中心的人，请他们完成一份问卷。(a) 说出抽样方法的名称。(b) 讨论该抽样方法对此项研究的一个优点和一个缺点。
Analysis: The method is opportunity sampling (or convenience sampling), as the researcher selects participants who are readily available at a specific location and time. The procedure of 'every tenth person' adds a systematic element but does not change the core convenience nature. An advantage is that it is quick, easy and cost-effective to gather data. A disadvantage is that the sample is likely unrepresentative – it only includes teenagers who visit that particular mall at that time, possibly excluding those from different socioeconomic backgrounds or interests, therefore limiting generalisability.
解析：该方法为机会抽样（或便利抽样），因为研究者选择在特定地点和时间容易接触到的人。“每第十个人”的步骤增加了一定的系统性，但不改变其便利本质。优点是快捷、简便且经济高效地收集数据。缺点是样本可能缺乏代表性——它只包含在特定时间光顾该购物中心的青少年，可能排除了不同社会经济背景或兴趣的人群，从而限制了普遍性。
For top marks, suggest a better alternative, such as stratified sampling by age, gender and socioeconomic status, and explain why it would enhance representativeness.
想要获得高分，应建议更好的替代方案，例如按年龄、性别和社会经济地位进行分层抽样，并解释为何能提高代表性。
5. Question 4: Ethical Issues | 题目 4：伦理议题
In a study on conformity, participants were told they were taking part in a visual perception task, but the real aim was to see if they would agree with a group who deliberately gave wrong answers. After the experiment, participants were not told the true purpose. Identify two ethical guidelines that were broken and explain how each could be resolved.
在一项从众研究中，参与者被告知他们正在参与一个视觉知觉任务，但真正目的是观察他们是否会同意故意给出错误答案的群体的意见。实验结束后，参与者未被告知真实目的。指出两项被违反的伦理准则，并解释每项如何解决。
Model response: The study involves deception because participants were misled about the true aim of the research. To resolve this, the researcher should have obtained presumptive consent or, at the end of the study, provided a full debriefing explaining the true nature and why deception was necessary. Secondly, the lack of debriefing also violates the right to withdraw and informed consent. The ethical breach can be dealt with by allowing participants to see their data and offering them the right to request data removal even after the session, fully restoring their autonomy.
范例回答：该研究涉及欺骗，因为参与者在研究的真实目的上被误导。为了解决这一问题，研究者本应获得预设同意，或在研究结束时提供完整的知情解释，说明真实性质和欺骗的必要性。其次，缺乏知情解释也侵犯了退出权和知情同意。解决这一伦理违背的方式是允许参与者查看自己的数据，并赋予他们在实验后要求删除数据的权利，从而充分恢复其自主权。
Always link ethical solutions to specific BPS guidelines: confidentiality, protection from harm, privacy, and the debrief must include the opportunity to ask questions.
始终将伦理解决方案与具体的英国心理学会 (BPS) 准则结合：保密、免受伤害、隐私，且知情解释必须包含提问的机会。
6. Question 5: Observation Techniques | 题目 5：观察技术
A researcher wants to investigate how children share toys in a nursery without interfering with their natural play. Suggest a suitable observation method and design. Explain two features of your design that would improve the quality of the data collected.
一位研究者想调查幼儿园中儿童如何分享玩具，而不干扰他们的自然游戏。建议一种合适的观察方法和设计。解释你的设计中能提高所收集数据质量的两个特征。
Recommendation and rationale: A covert naturalistic observation would be appropriate, where the researcher records behaviour via a one-way mirror or a hidden camera, ensuring the children are unaware they are being watched. This minimises participant reactivity and increases ecological validity. To improve data quality, the researcher should use a standardised behavioural checklist (e.g., 'offers toy', 'takes toy without asking', 'refuses to share') to operationalise sharing and allow inter-observer reliability checks. Second, conducting a pilot observation allows the categories to be refined so that they are mutually exclusive and cover all relevant behaviours.
建议与理据：隐蔽的自然观察法是合适的，研究者可通过单向镜或隐藏摄像头记录行为，确保儿童不知道自己被观察。这最小化了参与者反应性，提高了生态效度。为了提升数据质量，研究者应使用标准化的行为检查表（例如“主动给玩具”“未经请求拿走玩具”“拒绝分享”），将分享行为操作化，并可进行观察者间信度检查。其次，进行预观察可以使行为类别得到完善，确保它们互斥且涵盖所有相关行为。
Examiners look for precise terminology: 'overt vs covert', 'participant vs non-participant', 'structured vs unstructured'. Always justify choices in terms of validity and reliability.
考官寻求精确的术语：“公开 vs 隐蔽”、“参与 vs 非参与”、“结构化 vs 非结构化”。始终从效度和信度的角度为选择提供理由。
7. Question 6: Correlation vs Experiment | 题目 6：相关与实验
A study found a strong positive correlation between the number of hours teenagers spend on video games and their scores on a test of anger proneness. Some journalists concluded that violent video games cause aggressive personality traits. Discuss whether this conclusion is justified, using your knowledge of correlational research.
一项研究发现，青少年玩电子游戏的小时数与他们在愤怒倾向测试上的得分之间存在很强的正相关。一些记者得出结论，暴力电子游戏导致攻击性人格特征。讨论这一结论是否合理，并运用你的相关研究知识。
Answer: The conclusion is not justified because correlation does not imply causation. A positive correlation tells us that as one variable increases, the other tends to increase, but it does not establish a cause-and-effect relationship. There could be a third variable at play, such as pre-existing temperament, parental supervision, or socioeconomic stress, which influences both gaming time and anger. Additionally, the direction of causality is unclear: it is possible that children with higher anger tendencies choose to play video games for longer periods. An experiment manipulating game type while controlling extraneous variables would be needed to infer causation.
答案：该结论不合理，因为相关并不意味着因果关系。正相关告诉我们，当一个变量增加时，另一个也倾向于增加，但无法确立因果关系。可能存在第三个变量在起作用，例如先天的气质、父母监管或社会经济压力，它们同时影响游戏时间和愤怒程度。此外，因果方向不明确：可能愤怒倾向较高的儿童自己选择玩更长时间的游戏。要推断因果关系，需要设计实验操纵游戏类型并控制额外变量。
ole of intervening variables. Never claim causation from correlational data in psychology.
为了加强答案，可引用相关系数（如 r = +0.68）并强调中间变量的作用。在心理学中，绝对不要从相关数据中声称因果关系。
8. Question 7: Memory Models | 题目 7：记忆模型
Describe the multi-store model of memory, including the three stores and their key features. Evaluate one strength and one limitation of this model.
描述多存贮记忆模型，包括三个存贮库及其关键特征。评价该模型的一个优点和一个局限。
Knowledge outline: ). Sensory memory has a large capacity but very brief duration (milliseconds), coding information in modality-specific forms. STM has a limited capacity of around 7±2 chunks and duration of about 18– oding primarily semantically. Information moves from STM to LTM via elaborative rehearsal.
知识概要：多存贮模型（Atkinson 和 Shiffrin）提出了三个分离的存贮库：感觉记忆、短时记忆 (STM) 和长时记忆 (LTM)。感觉记忆容量大但持续时间极短（毫秒），以感觉通道特异性形式编码。STM 容量有限，约 7±2 个组块，在没有复述的情况下持续时间约 18–30 秒；编码主要为声学。LTM 容量和持续时间可能无限，编码主要为语义。信息通过精细复述从 STM 转入 LTM。
Evaluation: A strength is that the model is supported by brain scan evidence showing the prefrontal cortex is active during STM tasks and the hippocampus during LTM encoding, suggesting separate biological bases. A limitation is that it oversimplifies STM as a single, passive store; the working memory model by Baddeley and Hitch shows STM has multiple components, such as the central executive and phonological loop. The multi-store model also cannot explain why some amnesiacs can form new procedural memories but not episodic ones.
评价：优点是该模型得到了脑扫描证据的支持，显示在前额叶皮层在 STM 任务中活跃，而海马体在 LTM 编码中活跃，表明分离的生物基础。局限是它过度简化 STM，将其视为单一的被动存储；Baddeley 和 Hitch 的工作记忆模型显示 STM 有多个成分，如中央执行器和语音环路。多存贮模型也无法解释为何某些失忆症患者能形成新的程序性记忆却无法形成情节记忆。
9. Question 8: Classic Study – Loftus and Palmer | 题目 8：经典研究 – 洛夫特斯和帕尔默
Outline the procedure and findings of Loftus and Palmer’s (1974) experiment on eyewitness testimony. Discuss the practical implications of this research for the criminal justice system.
概述洛夫特斯和帕尔默 (1974) 关于目击证词的实验的程序和发现。讨论该研究对刑事司法系统的实际启示。
Procedure: eed of the vehicles. Different groups were given different verbs in the critical question: 'About how fast were the cars going when they _______ each other?' The verbs were 'smashed', 'collided', 'bumped', 'hit', 'contacted'. In Experiment 2, participants who heard the word 'smashed' ikely to report seeing broken glass when asked a week later, even though none was present.
程序：在实验 1 中，45 名学生参与者观看了交通事故的影片片段，然后被要求估计车速。不同组在关键问题中被给予不同的动词：“当两辆车互相 _______ 时，速度大约是多少？”动词包括“猛撞”“碰撞”“撞上”“撞击”“接触”。在实验 2 中，一周后被询问时，听到“猛撞”一词的参与者更可能报告看到了破碎的玻璃，尽管实际上并没有。
Findings and implications: The mean speed estimate was highest for 'smashed' (40.8 mph) and lowest for 'contacted' (31.8 mph). This demonstrates the misinformation effect, where post-event information alters memory. For the justice system, this implies that leading questions by police officers or lawyers can distort eyewitness recall, potentially leading to wrongful convictions. Therefore, interviews should avoid suggestive phrasing, and the use of the cognitive interview technique that encourages free recall is recommended.
发现与启示：平均速度估计在“猛撞”条件下最高（40.8 mph），在“接触”条件下最低（31.8 mph）。这显示了误导信息效应，即事后信息可以改变记忆。对司法系统而言，这意味着警察或律师的引导性问题可能扭曲目击者的回忆，可能导致冤假错案。因此，访谈应避免暗示性措辞，并建议使用鼓励自由回忆的认知访谈技术。
10. Question 9: Social Influence (Conformity) | 题目 9：社会影响（从众）
Describe Asch’s (1951) conformity experiment. Explain two factors that affect the level of conformity, using evidence from Asch’s variations.
描述阿施 (1951) 的从众实验。利用阿施变式中的证据，解释影响从众程度的两个因素。
Experiment outline: Asch recruited male college students to take part in what they thought was a vision test. They were placed in groups with confederates who unanimously gave wrong answers about which of three comparison lines matched a standard line. The genuine participant answered last or next-to-last. Across trials, about 75% of participants conformed at least once, and the overall conformity rate was around 37%.
实验概要：阿施招募了男大学生参加一个他们以为是视力测试的研究。他们与一群同伴（实验助手）组成小组，同伴们一致就三条比较线中哪一条与标准线匹配给出错误答案。真正的参与者最后一个或倒数第二个回答。在所有试验中，约 75% 的参与者至少从众了一次，总体从众率约为 37%。
Factors: Group size matters: conformity increased when there were at least three confederates, but adding more beyond that had little further impact. The presence of a dissenter dramatically reduced conformity: if one confederate gave the correct answer (or a different wrong answer), the participant’s conformity dropped to about 5%, because social support breaks the unanimity of the majority. A third factor is task difficulty: when the lines were made more similar, conformity rose, suggesting informational social influence plays a larger role in ambiguous situations.
因素：群体规模有影响：当至少有三名助手时从众程度增加，但超过三人后增加更多的作用不大。异议者的存在大大降低了从众：如果一名助手给出正确答案（或不同的错误答案），参与者的从众率降至约 5%，因为社会支持打破了多数人的一致性。第三个因素是任务难度：当线条变得更加相似时，从众上升，表明信息性社会影响在模糊情境中起更大作用。
11. Question 10: Essay Question on Attachment | 题目 10：依恋论文题
Discuss Bowlby’s theory of maternal deprivation. Refer to Bowlby’s 44 Thieves study and evaluate the theory in your answer.
讨论鲍尔比的母性剥夺理论。在你的回答中引用鲍尔比的 44 个小偷研究并对该理论进行评价。
Essay guidance: The 6-mark essay demands accurate description and critical analysis. Start by stating the core hypothesis: that prolonged separation from the primary caregiver during the critical period (first 2-3 years) can lead to permanent emotional and social damage, including affectionless psychopathy. In the 44 Thieves study, Bowlby interviewed 88 children, 44 of whom had a history of stealing, and 44 controls. He found that 86% of the 'affectionless psychopaths' had experienced early prolonged separation, compared to very few in the control group. This was used to support a link between maternal deprivation and later delinquency.
论文指导：这道 6 分论文题要求准确的描述和批判性分析。开篇陈述核心假设：在关键期（2-3 岁前）与主要照料者长期分离可能导致永久的情感和社会损伤，包括无情感型精神变态。在 44 个小偷研究中，鲍尔比访谈了 88 名儿童，其中 44 人有偷窃史，44 人为对照组。他发现 86% 的“无情感型精神变态者”曾经历早期长期分离，而对照组中比例极低。这被用来支持母性剥夺与青少年犯罪之间的关联。
Evaluation: A major weakness is
