1. Question 1: Identifying Variables | 第1题：识别变量
A researcher wants to test whether listening to classical music while studying improves memory recall. In the study, one group of pupils studies a list of words while listening to Mozart, and another group studies in silence. Both groups then try to recall the words. Identify the independent variable (IV) and the dependent variable (DV) in this experiment. (2 marks)
一位研究者想测试边听古典音乐边学习是否能提高记忆回忆。研究中，一组学生在听莫扎特音乐的同时记忆单词表，另一组在安静中学习；然后两组都尝试回忆单词。请指出这个实验中的自变量 (IV) 和因变量 (DV)。（2分）
The independent variable is the factor that the researcher deliberately changes or manipulates. Here, the researcher decides whether participants have music or silence. Therefore, the IV is the presence or absence of music (or 'listening condition'). The dependent variable is what is measured — the outcome that may be affected by the IV. In this study, it is the number of words correctly recalled, which indicates memory recall.
自变量是研究者有目的地改变或操纵的因素。在此，研究者决定参与者是否听音乐。因此，自变量是是否有音乐（或'听力条件'）。因变量是被测量的结果——可能受自变量影响的结果。在这个研究中，因变量是正确回忆出的单词数量，这代表了记忆回忆水平。
Model Answer: icipants listen to music or study in silence; DV = the number of words correctly recalled.
参考答案：自变量 = 参与者是否听音乐或安静学习；因变量 = 正确回忆出的单词数量。
2. Question 2: Experimental Design | 第2题：实验设计
In the same memory experiment, the researcher uses two separate groups: 20 pupils in the music group and 20 different pupils in the silence group. Name the experimental design used, and give one advantage and one disadvantage of this design. (3 marks)
在同一个记忆实验中，研究者使用了两组独立的参与者：20 名学生在音乐组，另外 20 名学生在安静组。请说出所使用的实验设计名称，并写出该设计的一个优点和一个缺点。（3分）
This is an independent groups design (also called between-participants design). An advantage is that there are no order effects, such as practice or fatigue, because each participant only experiences one condition. This keeps the two conditions uncontaminated by learning from the first task. A disadvantage is that participant variables between the two groups (e.g., natural memory ability, motivation) could differ and confound the results, unless careful random allocation is used.
这是独立组设计（也称被试间设计）。一个优点是没有顺序效应，例如练习效应或疲劳效应，因为每位参与者只经历一种条件。这避免了两个条件之间因学习第一个任务而相互污染。一个缺点是两组之间的参与者变量（如天生记忆能力、动机）可能不同并混淆结果，除非使用了仔细的随机分配。
Model answer: Independent groups design. Advantage: avoids order effects. Disadvantage: participant variables may differ between groups.
参考答案：独立组设计。优点：避免顺序效应。缺点：两组间的参与者变量可能有差异。
3. Question 3: Sampling Methods | 第3题：抽样方法
A psychologist wants to study sleep quality in teenagers. She puts a poster in the local library asking for volunteers aged 13–15. Name the sampling method used, and describe one strength and one weakness of this method. (3 marks)
一位心理学家想研究青少年的睡眠质量。她在当地图书馆张贴海报，招募 13–15 岁的志愿者。请说出所使用的抽样方法，并描述该方法的一个优点和一个缺点。（3分）
This is volunteer sampling (or self-selected sampling). A strength is that it is relatively easy and quick to obtain participants because they come to the researcher voluntarily. A weakness is that the sample is likely to be unrepresentative: volunteers may be more motivated, have more free time, or share a particular personality trait (e.g., high agreeableness), which reduces the generalisability of the findings to all teenagers.
这是志愿者抽样（或称自选抽样）。一个优点是相对容易且快速地获得参与者，因为他们自愿前来。一个缺点是样本可能不具代表性：志愿者可能更有动力、有更多空闲时间，或拥有某种特定人格特征（如高宜人性），这会降低研究结果对所有青少年的推广性。
Model answer: Volunteer sampling. Strength: convenient and saves time. Weakness: biased sample — volunteers may differ from the target population, limiting generalisability.
参考答案：志愿者抽样。优点：方便省时。缺点：样本有偏差——志愿者可能与目标人群不同，限制了研究结论的可推广性。
4. Question 4: Conformity – Asch’s Study | 第4题：从众——阿希实验
Asch (1951) carried out a famous study of conformity. Describe the key procedure of the study, and identify the type of conformity shown by most participants when they gave an obviously wrong answer. (2 marks)
阿希（1951）进行了一项著名的从众研究。请描述该研究的关键步骤，并指出大多数参与者给出明显错误答案时所表现出的从众类型。（2分）
In Asch’s procedure, a naive participant was placed in a group with several confederates who deliberately gave wrong answers in a line-judgement task. The real participant often conformed to the incorrect majority, even though the correct answer was obvious. The type of conformity displayed is called compliance (or public conformity), where the person changes their outward behaviour to fit in with the group, but does not necessarily change their private belief.
在阿希的研究步骤中，一位天真的参与者被安排与几位托儿同组，这些托儿在判断线段长度任务中故意给出错误答案。真正的参与者常常顺从错误的多数意见，即使正确答案显而易见。这里表现出的从众类型叫做顺从（或公开从众），即个体为融入群体而改变外显行为，但私下可能并未改变自己的信念。
Model answer: Participants judged line lengths after hearing confederates’ unanimous wrong answers. Type of conformity: compliance (public agreement, private disagreement).
参考答案：参与者在听到托儿们一致给出错误答案后判断线段长度。从众类型：顺从（公开服从，私下不从）。
5. Question 5: Obedience – Situational Factors | 第5题：服从——情境因素
Milgram’s research on obedience showed that ordinary people could be instructed to give what they believed were severe electric shocks. Explain how the proximity of the victim affected obedience levels. (2 marks)
米尔格拉姆关于服从的研究表明，普通人可以被指示地去施加以为他们认为是严重的电击。请解释受害者的接近程度如何影响服从水平。（2分）
Milgram found that when the victim was in a different room and unseen, obedience was highest (around 65% went to the maximum shock). When the victim was in the same room and visible, obedience dropped. In the 'touch proximity' condition, where the participant had to force the victim’s hand onto the shock plate, obedience fell dramatically. Closer proximity increases empathy and makes the consequences of one’s actions more salient, thereby reducing blind obedience to authority.
米尔格拉姆发现，当受害者在不同房间且不可见时，服从率最高（约65%的人一直施加到最高电压）。当受害者在同一房间且可见时，服从率下降。在'接触接近'条件下，参与者须将受害者的手按在电击板上，服从率急剧下降。更近的距离会增强共情，使自身行为的后果更加明显，从而减少对权威的盲目服从。
Model answer: Greater proximity / visibility of the victim lowered obedience; in the remote condition obedience was highest, while touch proximity produced the lowest obedience.
参考答案：与受害者更接近/更可见会降低服从；在遥控条件下服从率最高，而接触接近条件下服从率最低。
6. Question 6: Multi-Store Model of Memory | 第6题：记忆的多存储模型
Describe the three components of the multi-store model of memory, and explain why rehearsal is necessary to transfer information from short-term memory (STM) to long-term memory (LTM). (4 marks)
请描述记忆多存储模型的三个成分，并解释为什么复述对于将信息从短时记忆（STM）转入长时记忆（LTM）是必要的。（4分）
s incoming sensory information very briefly, for less than half a second. If we pay attention to it, the information is passed to STM, which has a limited capacity of about 7±2 items and a duration of around 18– sed enough, it is encoded into LTM, which has potentially unlimited capacity and duration.
多存储模型提出三个独立的储存库：感觉记忆、短时记忆（STM）和长时记忆（LTM）。感觉记忆极其短暂地（少于半秒）保存输入的感官信息。如果我们注意它，信息便进入 STM，其容量约为 7±2 个组块，持续时间大约 18–30 秒。复述（心理上重复信息）有两个作用：它使信息在 STM 中保持活跃，如果复述足够充分，信息就会被编码进入 LTM，而 LTM 拥有几乎无限的容量和持续时间。
Model answer: e : Three stores: Sensory memory (very brief, large capacity), STM (limited capacity 7±2, duration ~ that encodes information from STM to LTM; without it, decay or displacement occurs in STM.
参考答案：三个储存库：感觉记忆（非常短暂、大容量），STM（有限容量 7±2、约 20 秒时长），LTM（无限容量和时长）。复述是将信息从 STM 编码至 LTM 的主要过程；没有复述，STM 中的信息会出现衰减或替代。
7. Question 7: Attachment Types – The Strange Situation | 第7题：依恋类型——陌生情境测验
Mary Ainsworth’s 'Strange Situation' identified different attachment types. Describe the behaviour of a securely attached infant during the procedure, and explain why it suggests secure attachment. (3 marks)
玛丽·安斯沃思的'陌生情境'实验识别了不同的依恋类型。请描述安全型依恋的婴儿在实验中的行为，并解释这为何表明安全型依恋。（3分）
A securely attached infant uses the caregiver as a safe base from which to explore the unfamiliar room. When the caregiver leaves, the infant shows distress (separation anxiety) and seeks proximity upon reunion, but is quickly comforted and returns to exploration. This pattern indicates that the infant trusts the caregiver as a source of safety, reflecting a healthy attachment relationship formed through sensitive and responsive caregiving.
安全型依恋的婴儿会把照料者当作探索陌生房间的安全基地。当照料者离开时，婴儿表现出苦恼（分离焦虑），并在重聚时寻求亲近，但能很快被安抚并重新开始探索。这一模式表明婴儿信赖照料者是安全感的来源，反映了通过敏感、及时响应的照护所形成的健康依恋关系。
Model answer: Secure attachment: infant explores using caregiver as secure base, shows distress on separation, seeks comfort on reunion and is easily soothed. This shows the caregiver is a source of security.
参考答案：安全型依恋：婴儿以照料者为安全基地进行探索，分离时表现出不安，重聚时寻求安慰且容易被安抚。这表明照料者是安全来源。
8. Question 8: Personality and Self-Report Measures | 第8题：人格与自我报告测量
One way to measure personality is using a self-report inventory like the Big Five questionnaire. Discuss one strength and one limitation of using self-report methods in personality research. (4 marks)
测量人格的一种方式是使用诸如大五人格问卷等自我报告量表。请讨论在人格研究中使用自我报告法的一个优点和一个局限性。（4分）
A strength is that self-report methods allow researchers to access an individual’s internal thoughts, feelings, and self-concept directly — information that cannot be observed from the outside. They are also easy and cost-efficient to administer to large samples. A limitation is social desirability bias: respondents may answer in ways that make them look good rather than truthfully, for example, rating themselves as more conscientious or agreeable than they really are. Also, self-reports rely on participants having good self-awareness and honesty, which may not be consistent.
一个优点在于自我报告法能让研究者直接获取个体的内在想法、感受和自我概念——这些信息无法从外部观察到。而且，这种方法对大规模施测来说简便且成本低廉。一个局限是社会赞许性偏差：受测者可能会以让自己看起来更好的方式作答，而非如实回答，例如评价自己比实际更有责任心或更宜人。此外，自我报告依赖于参与者具有良好的自我觉察和诚实度，而这两者可能并不稳定。
Model answer: Strength: provides first-person insight into personality traits that are otherwise hidden. Limitation: answers may be distorted by social desirability bias, and they assume the person knows themselves accurately.
参考答案：优点：提供他人无法观察到的第一手人格特质信息。局限：回答可能因社会赞许性偏差而失真，且假设个体能准确了解自己。
9. Question 9: Data Analysis – Central Tendency | 第9题：数据分析——集中趋势
A psychologist collected the following scores from a memory test: 12, 14, 14, 15, 16, 17, 42. (a) Calculate the mean, median, and mode. (b) Which measure of central tendency best represents this data set, and why? (4 marks)
一位心理学家从一项记忆测试中收集到以下分数：12, 14, 14, 15, 16, 17, 42。(a) 计算平均数、中位数和众数。(b) 哪个集中趋势量数最能代表这组数据？为什么？（4分）
| Calculation | Value |
| Mean (sum/N) | (12+14+14+15+16+17+42) ÷ 7 = 18.57 |
| Median (middle value) | 15 |
| Mode (most frequent) | 14 |
The mean is pulled up by the extreme score of 42, making it unrepresentative of the typical performance. The median (15) is not affected by this outlier and sits comfortably in the middle of the majority of scores. Therefore, the median is the best measure of central tendency here because the data set contains an outlier and the median is a robust statistic that resists distortion by extreme values.
平均数被 42 这个极端值拉高，导致其不能代表典型的表现。中位数（15）不受此异常值影响，处于大多数分数的中心位置。因此，中位数是此处最佳的集中趋势量数，因为这组数据含有一个异常值，而中位数是一个抗极端值扭曲的稳健统计量。
10. Question 10: Ethical Issues | 第10题：伦理议题
In an obedience study, the researcher tells participants they are testing the effects of punishment on learning, but the true aim is to see how far they will obey an authority figure. After the study, participants are informed of the real purpose. Identify two ethical issues in this scenario, and suggest how each could be dealt with. (4 marks)
在一项服从研究中，研究者告诉参与者他们正在测试惩罚对学习的影响，但真正目的是观察他们会在多大程度上服从权威人物。研究结束后，参与者被告知真实目的。请识别这个情境中的两个伦理议题，并提出每个议题的应对方式。（4分）
The first ethical issue is deception — the participants were deliberately misled about the true aim of the study. To deal with this, researchers must avoid unnecessary deception and, if it is essential for the study, they must debrief participants thoroughly afterwards, revealing the true purpose and reasons for the deception. A second issue is lack of informed consent: because they were deceived, participants did not give fully informed consent. This can be addressed by seeking presumptive consent (asking a similar group) or by giving a full debrief and allowing participants to withdraw their data after learning the real purpose.
第一个伦理议题是欺骗——参与者被故意误导了研究的真实目的。为应对该问题，研究者必须避免不必要的欺骗，如果研究确实需要欺骗，事后必须充分向参与者做任务报告，揭示真实目的并解释欺骗的理由。第二项议题是缺乏知情同意：由于被欺骗，参与者未能给出完全知情的同意。这可以通过事先获得推定同意（询问相似群体）或在任务报告后允许参与者了解真相后撤回自己的数据来处理。
Model answer: (1) Deception — dealt with by thorough debriefing and justification. (2) Lack of fully informed consent — dealt with by obtaining presumptive consent and offering the right to withdraw data after debrief.
参考答案：(1) 欺骗——通过充分的任务报告和理由说明来应对。(2) 缺乏完全知情同意——通过获得推定同意和在任务报告后提供撤回数据的权利来应对。
