1. Multiple-Choice Question: Memory Encoding | 选择题：记忆编码
The first section of the mock paper tests your knowledge of how information enters memory. Consider the question below.
模拟卷第一部分考查信息如何进入记忆。请阅读下面的题目。
Question: Which type of encoding is most strongly associated with processing the meaning of words? A) Visual encoding B) Acoustic encoding C) Semantic encoding D) Tactile encoding
问题：下列哪种编码方式与处理单词的含义最密切相关？A) 视觉编码 B) 声学编码 C) 语义编码 D) 触觉编码
Correct answer: C) Semantic encoding.
正确答案：C) 语义编码。
Explanation: Semantic encoding involves linking new information to its meaning, which leads to deeper processing and better recall. Visual encoding deals with images, acoustic encoding with sounds, and tactile encoding is about touch. Research by Craik and Tulving showed that words processed semantically are remembered more effectively than those processed by appearance or sound.
解析：语义编码是把新信息与它的含义联系起来，这种深度加工能带来更好的回忆效果。视觉编码针对图像，声学编码针对声音，触觉编码则与触觉相关。克雷克和塔尔文的研究表明，经过语义加工的词比仅依靠外形或读音加工的词更容易被记住。
2. Key Terms: Independent and Dependent Variables | 术语解释：自变量与因变量
Understanding variables is essential for evaluating any experiment. Here is a typical short-answer question.
理解变量是评价任何实验的基础。下面是一道典型的简答题。
Question: Define 'independent variable' (IV) and 'dependent variable' (DV). Then, in a study testing whether background music affects concentration, identify the IV and DV.
问题：定义“自变量”（IV）和“因变量”（DV）。在关于背景音乐是否影响专注力的研究中，指出哪个是IV，哪个是DV。
Model answer: The independent variable is the factor the researcher manipulates or changes. The dependent variable is the factor that is measured; it depends on the IV. In the music study, the IV is the presence or type of background music, and the DV is the level of concentration, perhaps measured by a task score.
参考答案：自变量是研究者操纵或改变的因素。因变量是被测量的结果，它取决于自变量。在音乐研究中，IV是背景音乐的有无或类型，DV是专注程度，可以用任务得分来测量。
Examiner tip: Always phrase the DV as something you can quantify. Avoid vague terms like 'how well they focus' alone; link it to a specific measure.
考官提示：永远要把DV表述为可量化的指标。不要只用“他们有多专注”这种模糊说法，要结合具体的测量方式。
3. Short-Answer: The Multi-Store Model of Memory | 简答题：记忆的多存储模型
This question asks you to outline Atkinson and Shiffrin's influential model. Clarity and structure earn marks.
本题要求你概述阿特金森和希夫林提出的重要模型。清晰的结构能帮你得分。
Question: Outline the multi-store model of memory. Include the three stores and how information moves between them.
问题：概述记忆的多存储模型。要包含三个存储器，并说明信息如何在它们之间传递。
ster, where iconic and echoic memories last for about 0.5 seconds. If we pay attention, the information passes to short-term memory (STM). STM has a limited capacity of 7±2 chunks and a duration of around 18– unlimited capacity and duration. When we recall, information travels from LTM back to STM.
回答：该模型将记忆描述为在三个独立存储器之间流动的信息。首先，环境刺激进入感觉登记器，图像和声音记忆在此维持约0.5秒。如果我们集中注意力，信息就会进入短时记忆（STM）。STM的容量有限，为7±2个组块，持续时间约18–30秒。通过维持性复述，信息可以保留在STM中，或者被转移到长时记忆（LTM）。LTM的容量和时长几乎是无限的。当我们回忆时，信息从LTM返回到STM。
Common mistake: Do not confuse 'duration' and 'capacity'. Always mention the role of attention and rehearsal as control processes.
常见错误：不要混淆“时长”和“容量”。一定要提到注意和复述作为控制过程的作用。
4. Case Study: Conformity and Asch's Experiment | 案例分析：从众与阿希实验
In this section, you are given a scenario and must link it to psychological concepts. Read the case and the sample analysis.
在这部分，你会读到一个情境，需要把它与心理学概念联系起来。请看下面的案例和样本分析。
Scenario: Lucy is in a group of six people. Everyone except Lucy is a confederate. The group is asked to judge which of three lines is the same length as a standard line. The confederates all give an obviously wrong answer. Lucy feels uncertain but goes along with the group on several trials.
情景：露西在一个六人小组中。除露西外其他人都是同谋者。要求小组判断三条线中哪一条与标准线长度相同。所有同谋者都给出了明显错误的答案。露西虽然感到困惑，但在多次尝试中都跟着小组作出了回答。
Question: Identify the type of social influence Lucy experiences, using evidence from the scenario.
问题：指出露西经历的是哪种社会影响，并用情景中的证据加以说明。
Answer: Lucy demonstrates normative social influence. She wants to fit in and avoid rejection, so she publicly agrees with the group even though she privately knows the answer is wrong. This mirrors Asch's (1951) line study, where 75% of participants conformed at least once. The uncertainty she felt also suggests some informational influence, but her main motivation was to be accepted.
回答：露西表现出规范性社会影响。她希望融入群体、避免被排斥，所以公开赞同小组，即使私底下知道答案是错的。这与阿希（1951）的线段实验如出一辙，该实验中75%的参与者至少从众过一次。她感到的不确定也暗示了一些信息性影响，但主要动机是被接纳。
5. Research Design: Setting Up an Experiment | 研究设计：设计一个实验
Design questions test your ability to think like a researcher. Follow this worked example on the effect of caffeine on memory.
设计题检验你能否像研究者一样思考。请参考这个关于咖啡因对记忆影响的解题范例。
Question: A psychologist wants to investigate whether drinking a caffeinated drink before a test improves recall of word lists. Describe how she could conduct a laboratory experiment. Identify the IV, DV, and two control variables.
问题：一位心理学家想研究考试前喝含咖啡因饮料能否提高单词表的回忆成绩。请描述她如何开展实验室实验，并指出IV、DV和两个控制变量。
Proposed design: Recruit 30 students and randomly allocate them to two conditions. The experimental group receives a standard cup of coffee, while the control group receives decaffeinated coffee (placebo). Both groups then study the same list of 20 words for two minutes. After a five-minute distractor task, they write down all words they remember. The IV is whether the drink contained caffeine. The DV is the number of words correctly recalled. Control variables: words should be equally difficult for both lists; time allowed for studying must be identical; the same quiet room used for both groups.
实验设计方案：招募30名学生，随机分到两种条件。实验组喝一杯标准咖啡，控制组喝无咖啡因的咖啡（安慰剂）。两组都学习同样的20个单词，限时两分钟。经过五分钟的干扰任务后，他们写下记住的所有单词。IV是饮料是否含有咖啡因。DV是正确回忆出的单词数量。控制变量：两个单词表难度相当；学习时间一致；两组使用同一个安静的房间。
Ethical note: Always obtain consent from participants (and parents if under 16) and debrief them afterwards.
伦理提醒：务必获得参与者（未满16岁还需获得家长）的同意，并在事后进行释疑。
6. Graph Interpretation: Ebbinghaus's Forgetting Curve | 图表解读：艾宾浩斯遗忘曲线
Being able to read and explain graphs is a core skill. Let's interpret one of psychology's most famous curves.
能够读懂和解释图表是一项核心技能。让我们来解读心理学中最著名的曲线之一。
Graph description: The graph shows a steep drop in recall of nonsense syllables over the first hour, followed by a gradual levelling off. After one day, recall is around 30%, and after six days, it stabilises near 20%.
图表描述：曲线显示，在学习无意义音节后的第一个小时内，回忆量急剧下降，随后下降速度变缓。一天后回忆量约30%，六天后稳定在约20%。
Question: Explain what Ebbinghaus's forgetting curve reveals about the pattern of human forgetting.
问题：解释艾宾浩斯遗忘曲线揭示了人类遗忘的何种模式。
Answer: The curve demonstrates that forgetting is rapid immediately after learning, but then the rate slows down over time. Most information is lost within the first 9 hours if not rehearsed. This supports the idea that memory decays unless consolidated. It also shows the importance of rehearsal or revision shortly after learning to combat the early rapid loss.
回答：曲线说明，学习后遗忘发生得非常快，但随着时间推移，遗忘速度放慢。如果不进行复述，大部分信息会在头9小时内丢失。这支持了记忆不经巩固就会消退的观点，也突显了学习后尽早复习以对抗早期快速遗忘的重要性。
7. True or False: Sensation and Perception | 正误判断题：感觉与知觉
This part checks your understanding of basic sensory processes. Read each statement and our evaluation.
这部分检查你对基本感觉过程的理解。请阅读每项陈述和我们的评判。
Statement 1: 'The absolute threshold is the smallest amount of stimulus energy that can be detected 50% of the time.'
陈述1：“绝对阈限是指有一半的次数能检测到的最小刺激能量。”
Evaluation: True. This is the standard definition, often measured using a psychophysical method.
评判：正确。这是标准定义，通常用心理物理学方法测定。
Statement 2: 'Perception is a passive, bottom-up process that relies only on sensory input.'
陈述2：“知觉是一个被动的、完全依赖于感觉输入的自下而上过程。”
Evaluation: False. Perception is active and involves top-down processing, where expectations and past experience shape interpretation. For example, we see ambiguous figures differently based on context.
评判：错误。知觉是主动的，包含自上而下的加工，我们的预期和过往经验会影响解读。例如，对歧义图形的看法会因背景而异。
Statement 3: 'Weber's law states that the just noticeable difference is a constant proportion of the original stimulus intensity.'
陈述3：“韦伯定律指出，最小可觉差是原始刺激强度的一个恒定比例。”
Evaluation: True. For example, you would notice a 1% change in light brightness, but the same 1% would be undetectable for heavy weights.
评判：正确。比如，你能察觉到亮度1%的变化，但对于很重的重量，同样1%的变化就察觉不到。
8. Developmental Psychology: Piaget's Conservation Task | 发展心理学：皮亚杰守恒任务
You are likely to see a question about cognitive development stages. Here we examine conservation of number.
你很可能遇到关于认知发展阶段的问题。我们来看看数量守恒。
Scenario: A child watches as a researcher places two identical rows of 8 coins. When one row is spread out, the child says the longer row has more coins, even though no coins were added.
情景：研究人员先摆放两排各8枚硬币，排列完全一样。当其中一排被拉长后，孩子说长的一排硬币更多，尽管硬币数量没有增加。
Question: Explain why a child in the preoperational stage would give this answer, according to Piaget.
问题：根据皮亚杰的理论，解释为什么前运算阶段的孩子会这样回答。
Answer: In the preoperational stage (about 2–7 years), children lack the concept of conservation – the understanding that quantity remains the same despite changes in appearance. They are influenced by centration: focusing on only one aspect (length of the row) while ignoring the width and the fact that no coins were added. They also show irreversibility, unable to mentally reverse the spreading out. By the concrete operational stage, children solve this problem.
回答：在前运算阶段（约2–7岁），儿童尚未形成守恒概念——即明白即使外表改变，数量保持不变。他们会受到“集中化”的影响，只关注一个维度（队列长度），而忽略了宽度和硬币未增加的事实。他们还表现出“不可逆性”，无法在头脑中把拉长的队列恢复原状。到了具体运算阶段，儿童就能解决这个问题。
9. Ethical Issues: Using Deception in Research | 伦理讨论：研究中的欺骗
Ethics questions appear regularly. You need to balance research goals with participants' rights.
伦理题经常出现。你要在实现研究目标和保护参与者权利之间找到平衡。
Scenario: A study on aggression asks participants to play a video game. They are told it measures dexterity, but in fact frustration is being recorded. No harm occurs, but they were not told the true aim.
情景：一项关于攻击性的研究请参与者玩一款电子游戏。他们被告知是在测量敏捷度，但实际上记录的是受挫反应。虽然无人受到伤害，但他们不知道真实目的。
Question: Identify one ethical issue in this study and suggest how the researcher could address it.
问题：指出此研究中的一个伦理问题，并建议研究人员如何解决。
Answer: The key issue is lack of informed consent because the true aim was concealed. Deception is sometimes necessary to avoid demand characteristics, but participants must be debriefed afterwards. The researcher should explain the real purpose, offer the chance to withdraw their data, and ensure no distress remains. An ethics committee should approve the study beforehand.
回答：关键问题是缺乏知情同意，因为隐瞒了真实目的。有时为了避免需求特征需要使用欺骗，但事后必须进行释疑。研究者应解释真实目的，允许参与者撤回数据，并确保不会留下困扰。研究还需要事先获得伦理委员会的批准。
10. Data Handling: Calculating and Interpreting Averages | 数据处理：计算与解读平均数
The final section tests basic statistical skills. You will be given a small data set and asked to compute descriptive statistics.
最后一部分考查基本的统计技能。你会拿到一组小数据，计算描述性统计量。
Data: Memory test scores (words recalled) for participants in a quiet room: 12, 15, 9, 13, 16, 11.
数据：安静房间中的参与者记忆测试成绩（回忆单词数）：12, 15, 9, 13, 16, 11。
Question: Calculate the mean and the range of this data set. Explain what the range tells you about the scores.
问题：计算这组数据的平均数和全距。解释全距告诉我们关于分数的什么信息。
re are 6 scores. Mean = 76 ÷ 6 = 12.67 (to two decimal places). Range = highest score (16) – lowest score (9) = 7.
计算过程：总和 = 12 + 15 + 9 + 13 + 16 + 11 = 76。有6个分数。平均数 = 76 ÷ 6 ≈ 12.67（保留两位小数）。全距 = 最高分（16）- 最低分（9）= 7。
Interpretation: The mean represents a typical performance. The range of 7 shows that scores vary; there is a spread of 7 words between the best and worst performers. A smaller range would suggest more uniform performance, while a large range might indicate individual differences or reliability issues in the test.
解读：平均数代表典型表现。全距为7表明分数有差异，最高与最低分之间相差了7个单词。较小的全距意味着表现更均匀，而较大的全距可能指示个体差异较大或测验信度有问题。
Always double-check your arithmetic and include the correct units (e.g., words recalled).
一定要复查计算过程，并填写正确的单位（如：回忆单词数）。
