1. Describing a Control in Dement & Kleitman (1957) | 描述 Dement & Kleitman 研究中的控制措施
Question: Describe one control used in the study by Dement and Kleitman (1957) on sleep and dreaming. [4]
问题：描述 Dement 和 Kleitman (1957) 睡眠与梦境研究中使用的一项控制措施。 [4]
A strong answer identifies a specific procedural control and explains how it minimised confounding variables. For example, participants were instructed to avoid caffeine and alcohol on the day of the study, and they were woken up by a standardised loud doorbell at predetermined times determined by EEG. The doorbell ensured that the awakening stimulus was identical across all REM and NREM awakenings, so any differences in dream recall could not be attributed to variation in the method of waking. The EEG provided objective, physiological identification of sleep stages, removing reliance on subjective self-report of when a participant was in REM sleep. This control increased internal validity by isolating the variable of sleep stage.
高分答案会指出一项具体的程序控制并解释它如何减少混淆变量。例如，参与者被要求在实验当天避免摄入咖啡因和酒精，并且在 EEG 确定的预设时间被一个标准化的响亮门铃唤醒。门铃保证了所有 REM 和 NREM 唤醒中刺激完全相同，因此梦境回忆的任何差异都不能归于唤醒方式的差异。EEG 提供了对睡眠阶段的客观生理识别，避免依赖主观报告来判断参与者是否处于 REM 睡眠。这项控制通过隔离睡眠阶段这一变量，提高了内部效度。
2. Cognitive Labelling in Schachter & Singer (1962) | Schachter & Singer 研究中的认知标签
Question: Explain how the study by Schachter and Singer (1962) shows that cognitive labelling affects emotion. [4]
问题：解释 Schachter 和 Singer (1962) 的研究如何表明认知标签影响情绪。 [4]
The core demonstration lies in the comparison between the informed and uninformed adrenaline groups. Participants who had been injected with adrenaline but were not told about its true side effects (misinformed or ignorant) were placed with a euphoric or an angry stooge. Their physiological arousal was identical to that of the informed group, yet they reported and displayed emotions matching the stooge’s mood. For instance, uninformed participants in the euphoria condition joined in paper games and rated themselves as happier. This pattern shows that when the cause of arousal is ambiguous, individuals search the environment for cues and cognitively label their arousal as a specific emotion – joy or anger. The informed group, who had an explanation for their arousal, did not adopt the stooge’s emotion, confirming that cognitive appraisal, not just physiology, shapes emotional experience.
核心证据在于知情与不知情肾上腺素组的比较。注射了肾上腺素但未被告知真正副作用（误告知或不知情）的参与者与欣快或愤怒的假被试共处。他们的生理唤醒水平与知情组完全相同，却在报告和行为上表现出与假被试情绪一致的表现。例如，欣快情境中不知情的参与者加入纸片游戏并自评更快乐。这一模式表明，当唤起的原因模糊时，个体通过搜索环境线索来认知性地将生理唤醒标记为特定情绪——喜悦或愤怒。而知情组因为有了解释，并未采纳假被试的情绪，这证实了认知评价而不仅是生理状态塑造了情绪体验。
3. Doodling and Concentration (Andrade, 2010) | 涂鸦与注意力 (Andrade, 2010)
Question: From the study by Andrade (2010), explain one reason why doodling might improve concentration. [4]
问题：依据 Andrade (2010) 的研究，解释涂鸦可能提升注意力的一个原因。 [4]
Andrade argued that doodling helps to maintain arousal and prevents daydreaming. In the study, participants who shaded printed shapes while listening to a monotonous telephone message recalled 29% more information (names and places) than the control group. Doodling imposes a small cognitive load that occupies just enough executive resources to stop the mind from wandering into off‑task thoughts, yet it does not interfere with the primary listening task because it does not compete for verbal working memory. In essence, doodling acts as a stabiliser of vigilance, keeping the participant alert during a boring task without dividing attention in a harmful way.
Andrade 认为涂鸦有助于维持唤醒水平并防止做白日梦。研究中，边听单调电话留言边给印好的图形涂色的小组比对照组多回忆出 29% 的信息（名字和地点）。涂鸦施加了一种轻微的认知负荷，恰好占用足够的执行资源，阻止思维游离到任务之外，同时又不会干扰主要听力任务，因为它不与言语工作记忆发生竞争。简言之，涂鸦像是一个警觉性的稳定器，让参与者在枯燥任务中保持清醒而又不至于有害地分散注意力。
4. Sampling in Canli et al. (2000) | Canli et al. 研究中的样本评估
Question: Evaluate the sample used in Canli et al. (2000) on brain scans and emotional memory. [6]
问题：评价 Canli et al. (2000) 脑扫描与情绪记忆研究中所用的样本。 [6]
Canli et al. used a sample of 10 right‑handed, healthy female volunteers. This sample was highly homogeneous, which is a strength in brain imaging research because it reduces extraneous variables such as handedness (which affects lateralisation) and sex (which may affect emotional processing), thereby increasing internal validity. However, the small size and narrow demographic range severely limit generalisability. The findings about amygdala activation correlating with emotional memory may not apply to males, left‑handed individuals, children, elderly people or clinical populations. Furthermore, volunteer sampling may attract individuals who are more interested in science or have higher tolerance for scanners, producing a self‑selection bias. A balanced evaluation must weigh the gain in experimental control against the loss of population validity.
Canli 等人使用了 10 名右利手的健康女性志愿者作为样本。该样本高度同质，这在脑成像研究中是一个优势，因为它减少了利手（影响偏侧化）和性别（可能影响情绪加工）等额外变量，从而提高了内部效度。然而，小样本和窄人口学范围严重限制了推广性。关于杏仁核激活与情绪记忆相关的发现，可能不适用于男性、左利手人群、儿童、老年人或临床群体。此外，志愿者取样可能吸引对科学更感兴趣或对扫描仪忍受度更高的人，产生自选偏差。均衡的评价必须权衡实验控制的增益与人口效度的损失。
5. Ethics in Milgram (1963) | Milgram 实验中的伦理考量
Question: Discuss the ethical considerations in Milgram’s (1963) study on obedience. [8]
问题：讨论 Milgram (1963) 服从研究中的伦理考量。 [8]
Milgram’s study raised profound ethical issues that have shaped modern guidelines. The paramount concern was deception: participants genuinely believed they were administering real shocks to a fellow participant, and they were misled about the purpose of the study. While debriefing occurred afterwards, the experience of extreme stress was real. Many participants showed signs of tension such as sweating, trembling, and nervous laughter, indicating that protection from psychological harm was compromised. Furthermore, the right to withdraw was undermined by prods such as “the experiment requires that you continue”, making participants feel they could not leave freely. On the other hand, Milgram argued that the debriefing and follow‑up showed no lasting damage, and 84% of participants said they were glad to have taken part. A cost–benefit analysis must balance the distress caused against the immense contribution to understanding blind obedience. Today, such a study would not receive ethical approval without substantial modifications, including pre‑screening, on‑going consent reminders and the right to withdraw without penalty.
Milgram 的研究引发了影响现代伦理准则的深远议题。最首要的是欺骗：参与者真心以为自己在对另一位参与者施加真实电击，并被误导了研究目的。尽管事后进行了释疑，极度压力的体验却是真实的。许多参与者表现出出汗、颤抖和紧张发笑等痛苦迹象，这表明免受心理伤害的保护遭到破坏。此外，“实验要求你继续”之类的督促削弱了退出权利，使参与者感到无法自由离开。但 Milgram 辩称，释疑和随访显示没有持久伤害，且 84% 的参与者表示很高兴参与。成本–收益分析必须在造成的痛苦与对理解盲目服从的巨大贡献之间权衡。今天，此类研究若无重大修改（包括预先筛选、持续提醒同意权和不受惩罚的退出权）将很难获得伦理批准。
6. Designing a Questionnaire on Stress | 设计关于压力的问卷
Question: Design a questionnaire to investigate stress levels in students. Include operationalisation of stress, two example questions, and one ethical safeguard. [10]
问题：设计一份调查学生压力水平的问卷，包括压力的操作定义、两道例题和一项伦理保障措施。 [10]
Stress can be operationalised as a score on a self‑report scale measuring perceived stress over the past month, using items adapted from the Perceived Stress Scale (PSS). Two example closed questions are: “In the last month, how often have you felt difficulties were piling up so high that you could not overcome them?” (0 = never, 4 = very often) and “In the last month, how often have you felt nervous and stressed?” (same scale). Both items use a 5‑point Likert scale, generating quantitative data that can be totalled for a stress index. An essential ethical safeguard is ensuring anonymity; no names or identifiable information are collected, and participants are informed that all responses will be kept confidential. A consent paragraph precedes the questionnaire stating that participation is voluntary and that they may skip any question. These measures minimise social desirability bias and protect the participants’ well‑being.
压力可操作化为过去一个月感知压力量表的自评得分，题目改编自感知压力量表 (PSS)。两道封闭式例题为：“过去一个月，你有多频繁感到困难堆积如山而无法克服？”（0 = 从不，4 = 非常频繁）及“过去一个月，你有多频繁感到紧张和压力？”（相同量表）。两题均采用 5 点李克特量表，生成可加总为压力指数的量化数据。一项关键的伦理保障是确保匿名性：不收集姓名或可识别信息，并告知参与者所有回答将保密。问卷开头附有知情同意段落，说明参与完全自愿且可跳过任何问题。这些措施能降低社会赞许性偏差并保护参与者的福祉。
7. False Memories in Laney et al. (2008) | Laney et al. 研究中的虚假记忆
Question: Using the study by Laney et al. (2008), explain how false memories can be created and discuss one practical implication. [8]
问题：运用 Laney et al. (2008) 的研究，解释虚假记忆如何被制造并讨论一个实际应用意义。 [8]
Laney et al. demonstrated that false food‑preference memories can be implanted through a multi‑step imagination procedure. Participants completed a food history questionnaire and were later falsely told that a computer analysis revealed they had “got sick after eating egg salad” or “loved asparagus” as a child. They then engaged in guided imagination exercises picturing the scenario. One week later, many participants in the false‑feedback condition reported a weaker preference for egg salad or a stronger preference for asparagus, and some even claimed they remembered the event happening. This shows that a credible source combined with imagination inflation can alter autobiographical memory. A major practical implication is in the legal field: eyewitness testimony may be contaminated by repeated suggestive questioning or visualisation techniques, leading to wrongful convictions. Professionals should use open‑ended, non‑leading interviews to minimise the risk of implanting false memories.
Laney 等人证明，通过多步骤想象程序可以植入虚假的食物偏好记忆。参与者填写了食物历史问卷，随后被错误告知计算机分析显示他们童年“吃鸡蛋沙拉后生病”或“酷爱芦笋”，接着进行引导想象。一周后，虚假反馈组的许多参与者对鸡蛋沙拉偏好降低或对芦笋偏好升高，有些人甚至声称记得该事件发生过。这表明，可信信源与想象膨胀相结合可以改变自传体记忆。一个重要的实际意义在司法领域：目击者证词可能因反复暗示性询问或可视化技术而被污染，导致冤假错案。专业人士应采用开放式、非引导性提问，以最小化植入虚假记忆的风险。
8. Situation vs. Personality Debate | 情境与人格之辩
Question: “Behaviour is determined by the situation rather than personality.” Discuss this statement using evidence from social psychology studies. [12]
问题：“行为由情境而非人格决定。”用社会心理学研究的证据讨论这句话。 [12]
A powerful argument for situational determination comes from Milgram (1963), where 65% of participants obeyed an authority figure and delivered the maximum 450‑volt shock. The physical presence of the experimenter in a lab coat, the prestigious setting of Yale University, and the graduated shock procedure created a powerful situation that overrode personal conscience. Similarly, Piliavin et al. (1969) found that help was offered more often when the victim appeared ill (95%) than drunk (50%), and that the number of bystanders influenced helping speed, supporting situational factors like perceived responsibility. However, personality cannot be dismissed entirely. Even in Milgram’s study, 35% defied authority, and some participants showed personality‑linked variations in obedience scores in replication studies. A more balanced view is the interactionist perspective: behaviour emerges from a dynamic interplay between dispositional factors (e.g. locus of control, empathy) and situational pressures. A table summarising key evidence can clarify this debate:
情境决定行为的有力论据来自 Milgram (1963)：65% 的参与者服从权威人物，施加了最高 450 伏电击。实验者身穿实验服在现场的物理存在、耶鲁大学的权威环境以及逐渐升高的电击程序共同营造了压倒个人良知的情境。同样，Piliavin 等人 (1969) 发现，当受害者表现为疾病时获得帮助的比例 (95%) 高于醉酒 (50%)，且旁观者人数影响帮助速度，支持了感知责任等情境因素。然而，人格也不能完全排除。即使 Milgram 研究中也有 35% 的人反抗权威，而复制研究中一些参与者的服从分数显示出与人格相关的差异。更平衡的观点是交互论：行为产生于素质因素（如控制点、共情）与情境压力的动态互动。下表总结的关键证据可以厘清这一辩论：
| Study | Evidence for situational influence | Evidence for dispositional influence |
|---|---|---|
| Milgram (1963) | 65% full obedience in strong authority context. | 35% refused; personality scales show some predictive value. |
| Piliavin et al. (1969) | Ill victim helped more; diffusion of responsibility with more bystanders. | Individual helping rates varied despite identical situations. |
| Milgram variations | Obedience fell to 10% when experimenter gave orders by phone. | Still, a minority followed the telephoned orders to the end. |
An evaluative conclusion must recognise that extreme situations exert a powerful influence, yet individual differences still matter. The best exam answers use the interactionist stance, citing specific data to show that neither side alone fully explains behaviour.
评价性的结论必须承认极端情境确实施加了强大影响，但个体差异仍然重要。最佳的考试答案采用交互论立场，引用具体数据说明任何单一因素都无法完全解释行为。
9. Common Pitfalls and Model Answers | 常见错误与高分答案
One frequent mistake is describing a study without linking it explicitly to the question. When a question asks for an evaluation of a sample, simply listing ‘10 women’ without explaining why it matters will stay in the Level 1 mark band. Always state the implication for validity or generalisability. Another pitfall is failing to operationalise variables in a design question; saying ‘measure stress’ is insufficient – you must specify the tool (e.g. Perceived Stress Scale) and how scores are quantified. Additionally, confused terminology, such as using ‘reliability’ when ‘validity’ is needed, loses marks. Practise extracting the command word and customising your response: ‘Explain’ requires a causal mechanism, while ‘Discuss’ demands arguments for and against with a final judgement.
常见错误之一是描述研究时未能将其明确联系到题目。当要求评价样本时，仅仅列举“10 位女性”而不解释其意义将停留在低分数段。必须明确它对效度或推广性的影响。另一个陷阱是在设计题中未能操作化变量；说“测量压力”不够——你需要指定工具（如感知压力量表）并说明如何量化分数。此外，术语混淆，如将“信度”用在需要“效度”的地方，也会失分。练习提取指令词并定制回答：“解释”要求因果机制，而“讨论”则需要正反论点并给出最终判断。
