1. Multiple-Choice on Multi-Store Memory | 记忆的多存储模型选择题

Question: According to the multi-store model of memory, information flows in which order?

A) Short-term memory → Sensory register → Long-term memory
B) Sensory register → Long-term memory → Short-term memory
C) Sensory register → Short-term memory → Long-term memory
D) Long-term memory → Short-term memory → Sensory register

The correct answer is C. The multi-store model, proposed by Atkinson and Shiffrin, describes three separate stores. Information first enters the sensory register, where it is held very briefly. If attention is paid, it moves to short-term memory; through rehearsal, it may then be encoded into long-term memory. Option A reverses the sensory and short-term stages, while B and D incorrectly include long-term memory before short-term storage in a forward sequence. Remember the flow: sensory input → sensory register → attention → short-term memory → rehearsal → long-term memory.

正确答案是 C。由 Atkinson 和 Shiffrin 提出的多存储模型描述了三个独立的存储系统。信息首先进入感觉登记器，在那里短暂停留。如果受到注意，就会转移至短时记忆；通过复述，信息可能被编码进入长时记忆。选项 A 颠倒了感觉和短时阶段，而 B 和 D 错误地将长时记忆置于短时存储之前。请牢记这个流程：感官输入 → 感觉登记器 → 注意 → 短时记忆 → 复述 → 长时记忆。

2. Short-Answer on Depth Cues | 深度线索简答题

Question: Identify and explain one monocular depth cue that an artist can use to create the illusion of depth on a flat canvas. (2 marks)

Model answer: One monocular depth cue is linear perspective. This is where parallel lines appear to converge as they recede into the distance. An artist can draw a road with two lines that get closer together towards the horizon, making the scene look three-dimensional. Award 1 mark for naming a valid cue (e.g., relative size, texture gradient, interposition) and 1 mark for a correct explanation linked to the artistic example. Avoid simply repeating the term; the explanation must show how the cue creates depth.

参考答案：一种单眼深度线索是线条透视。这是指平行线在延伸到远方时看起来汇聚在一起。艺术家可以画一条路，让两条线在接近地平线时逐渐靠拢，从而使画面看起来具有三维感。答出有效的线索名称（例如相对大小、纹理梯度、遮挡）得 1 分，结合艺术例子进行合理解释再得 1 分。不要只是重复术语；解释必须展示该线索如何产生深度效果。

3. Conformity Scenario Question | 从众情境题

Question: Sophie is in a group where everyone else agrees that a clearly long line is actually longer than a standard line, even though Sophie can see they are the same length. She says the same as the group to avoid standing out. Name and describe the type of conformity shown by Sophie. (3 marks)

Sophie displays compliance. Compliance occurs when an individual publicly agrees with the group’s opinion or behaviour but privately disagrees. Sophie knew the lines were actually the same length, yet she conformed publicly to fit in. This matches Asch’s classic line-judgment studies where participants sometimes gave an incorrect answer to avoid rejection. 1 mark is awarded for correctly naming compliance; 2 further marks require describing the public-private distinction and linking it to Sophie’s behaviour.

Sophie 表现出了顺从。顺从是指个体公开赞同群体的意见或行为，但私下持有不同看法。Sophie 明白线段实际上一样长，但她为了合群而公开服从。这正符合 Asch 经典的线段判断实验，参与者为避免被排斥而给出错误答案。正确说出“顺从”得 1 分；另外 2 分需要描述公开与私下的区别，并将此与 Sophie 的行为挂钩。

4. Research Methods: Identifying Variables | 研究方法：变量识别

Question: A psychologist investigates whether drinking water improves memory. One group drinks 500 ml of water before a memory test; another group drinks no water. In this experiment, what is the independent variable (IV) and what is the dependent variable (DV)? (2 marks)

The independent variable is the factor manipulated by the researcher: the amount of water consumed (or the presence vs. absence of water). The dependent variable is the outcome measured: memory performance on the test. A common mistake is to state simply ‘water’ and ‘memory’ without specifying how they are operationalised. For full marks, link IV and DV to the experimental conditions: IV = whether participants drank water (two levels: 500 ml vs. none); DV = score on the memory test.

自变量是研究者操纵的因素：饮水量（或有水 vs. 无水）。因变量是测量的结果：记忆测试的成绩。常见错误是仅仅说“水”和“记忆”，而没有说明它们是如何被操作定义的。要拿满分，需要将 IV 和 DV 与实验条件联系起来：IV = 参与者是否饮水（两个水平：500 ml 与不饮水）；DV = 记忆测试的得分。

5. Graph Interpretation: Ebbinghaus Forgetting Curve | 图表解读：艾宾浩斯遗忘曲线

Question: The graph below shows Ebbinghaus’s forgetting curve. Describe the pattern of forgetting and explain what it tells us about memory retention. (3 marks)

[Insert graph showing rapid initial drop then levelling off over time]

The curve shows a very rapid loss of information shortly after learning, followed by a gradual levelling off. Most forgetting happens within the first hour; after a day, the amount forgotten decreases much more slowly. This tells us that memory fades quickly without rehearsal, but once a memory survives the initial period, it becomes more stable over time. For 3 marks, students should mention the initial steep drop, the subsequent plateau, and the implication for revision strategies: spreading out practice over time (the spacing effect) can combat this rapid forgetting.

该曲线表现出学习后不久信息迅速丢失，然后逐渐趋于平缓。大部分遗忘发生在第一个小时内；一天后，遗忘的速度减慢很多。这告诉我们，如果没有复述，记忆会迅速衰退，但一旦记忆熬过初期，它会随时间变得更稳定。拿到 3 分需要提到最初的急剧下降、随后的平台期，并指出对复习策略的启示：分散练习（间隔效应）可以对抗这种快速遗忘。

6. Visual Illusions: Explanations | 视觉错觉：机理解释

Question: Explain the Müller-Lyer illusion using the misapplied size-constancy theory. (4 marks)

The Müller-Lyer illusion consists of two lines of equal length, one with arrowheads pointing inward and the other with arrowheads pointing outward. The inward-pointing fins make the line appear longer. According to Richard Gregory’s misapplied size-constancy theory, our brain interprets the converging fins as a distant outside corner of a building, while the diverging fins resemble a nearer inside corner. Because the retinal images are the same size but perceived depth differs, the brain scales the ‘distant’ line as larger – hence the illusion. For full marks, explicitly link the fin directions to depth cues and the scaling mechanism. Alternative explanations like conflicting cues or top-down processing may also be credited if clearly related to the illusion.

缪勒-莱耶尔错觉由两条等长的线段组成，一条两端箭头朝内，另一条朝外。箭头朝内的图形使线段看起来更长。根据 Richard Gregory 的误用大小恒常性理论，我们的大脑将向内汇聚的箭头解释为一座建筑远处的墙角，而向外发散的箭头则类似于近处的墙角。由于视网膜像大小相同但感知深度不同，大脑便把“远处”的线段放大 —— 这就产生了错觉。想要满分，需要明确将箭头方向与深度线索及缩放机制联系起来。如果能够清晰地与错觉关联，冲突线索或自上而下加工等替代解释也可能得分。

7. Obedience Case Study Analysis | 服从案例分析

Question: In a replication of Milgram’s experiment, a teacher is asked to administer increasingly strong electric shocks to a learner. Outline two situational factors that affect obedience and explain how each was present in Milgram’s original study. (4 marks)

One situational factor is the proximity of the authority figure. In the baseline condition, the experimenter sat a few feet away, prompting 65% full obedience. When the experimenter gave orders by telephone, obedience dropped sharply because the pressure felt less immediate. A second factor is the prestige of the setting. Milgram conducted the study at Yale University, a prestigious institution, which gave the experiment an air of legitimacy and increased obedience compared to a run-down office. Students should name two factors and describe the variation conditions that altered obedience levels. Avoid simply listing personality factors – the question targets situational influences.

一个情境因素是权威人物的接近性。在基线条件下，实验者坐在几英尺之外，导致 65% 的完全服从。当实验者通过电话下达命令时，服从率急剧下降，因为感受到的压力不那么直接。第二个因素是环境的声望。Milgram 的研究在耶鲁大学这个有声望的机构进行，为实验增添了合法性，与破旧办公室相比提高了服从度。考生应说出两个因素，并描述改变服从水平的变体条件。要避免单纯列举人格因素 —— 本题针对的是情境影响。

8. Experimental Design Evaluation | 实验设计评估

Question: A teacher uses an independent groups design to test whether background music improves spelling test scores. One class listens to classical music; another class takes the test in silence. Explain one strength and one weakness of using an independent groups design in this scenario. (2 + 2 marks)

A strength is that there are no order effects. Since each participant experiences only one condition, they cannot become bored or practised, which might occur in a repeated measures design where everyone does both music and silence. A weakness is the risk of participant variables acting as confounding variables. The two classes might differ in average spelling ability before the experiment, so any difference in scores could be due to pre-existing differences rather than the music. To control this, random allocation of students to conditions would be essential. Marks are given for clear identification and specific application to the music/spelling context, not just generic textbook definitions.

一个优点是没有顺序效应。因为每位参与者只经历一种条件，他们不会变得厌倦或熟练，而在重复测量设计中，每个人都要完成音乐和安静两种条件，就可能出现顺序效应。一个缺点是参与者变量可能成为混淆变量。两个班级的实验前拼写能力可能存在差异，因此任何分数差异都可能源于先已存在的差异，而非音乐的影响。要控制这一点，必须将学生随机分配到不同条件。得分要点是清晰识别并在音乐/拼写情境中具体应用，而非泛泛地照搬教科书定义。

9. Short-Answer on Research Ethics | 研究伦理简答题

Question: A psychologist wants to interview teenagers about their experiences of bullying. Describe two ethical issues the psychologist must consider and suggest a way to deal with each. (4 marks)

One ethical issue is informed consent. Teenagers under 16 cannot legally give full consent; parents or guardians must provide consent, and the researcher should also obtain the young person’s assent. A suitable solution is to send an information letter detailing the study aims, procedures, and right to withdraw, and ask both the parent and the teenager to sign a consent/assent form. Another issue is confidentiality, because bullying disclosures could be sensitive. The psychologist must anonymise data, use pseudonyms in the report, and only break confidentiality if there is a risk of serious harm. Storing data securely and reminding participants of the limits of confidentiality beforehand are practical steps. 1 mark per correctly identified issue and 1 mark per applicable solution.

一个伦理问题是知情同意。16 岁以下的青少年在法律上不能给予完全同意；必须由家长或监护人提供同意，同时研究者还应获得青少年的赞同。一个适当的解决方案是发送信息函，详述研究目的、流程和退出权，并要求家长和青少年都签署同意/赞同表。另一个问题是保密性，因为欺凌的披露可能非常敏感。心理学家必须将数据匿名化，在报告中使用化名，只有在存在严重伤害风险时才打破保密。提前安全存储数据并提醒参与者保密的限度是切实可行的步骤。每正确识别一个伦理问题得 1 分，每个可行的应对方案再得 1 分。

10. Application: Combining Theory and Method | 综合应用：理论与方法结合

Question: Design a study to investigate the effect of peer pressure on risk-taking in Year 8 students. In your answer, you should: state the hypothesis, identify the independent and dependent variables, describe the procedure, and explain how you would analyse the results. (6 marks)

A suitable hypothesis: ‘Year 8 students will take significantly more risks on a simulated betting game when in a group of peers compared to when alone.’ The IV is the social condition (alone vs. group of 3 peers). The DV is the number of risky bets placed, operationally defined as bets on outcomes with a probability of winning lower than 30%. The procedure might involve 40 students randomly allocated to either condition; in the group condition, the three peers are confederates who deliberately suggest risky options. Afterwards, compare the mean number of risky bets between the two groups using a bar chart. To analyse, we could calculate the difference in means and consider whether the difference is large enough relative to the spread of data. For 6 marks, ensure the hypothesis is testable and directional, all variables are operationalised, and the analysis plan moves beyond simple description to a comparison of central tendency.

一个合适的假设：“在模拟赌博游戏中，Year 8 学生在同伴群体中会比独自一人时进行显著更多的冒险行为。” IV 是社会条件（独自 vs. 3 名同伴组成的群体）。DV 是做出的冒险赌注数量，操作定义是投注于赢的概率低于 30% 的结果。程序可包括 40 名学生随机分配至两种条件；在群体条件下，三名同伴为同谋，故意建议冒险选项。之后，用柱状图比较两组冒险赌注的平均数。分析时可以计算平均值差异，并考虑这个差异相对于数据分布是否足够大。拿下 6 分需确保假设可检验且具有方向性，所有变量均已操作化，分析计划不仅限于简单描述，还要包括集中趋势的比较。

11. Common Mistakes in 6-Mark Questions | 6分拓展题常见误区

Many Year 8 marks are lost on extended response questions. The most frequent errors include: writing everything known about a topic instead of directly answering the question; failing to operationalise variables when describing a study design; and neglecting to link back to the scenario provided. For instance, in a question on reducing prejudice, a student might describe Sherif’s Robbers Cave study but forget to explain how superordinate goals were created in that specific context. To avoid these pitfalls, always highlight the command word (describe, explain, design) and mirror the wording of the question in your opening sentence. Write a brief plan: state your point, apply it to the scenario, and then elaborate with psychological terminology. This ‘point-application-elaboration’ structure can lift a mediocre answer to a clear, focused one.

许多 Year 8 学生在拓展回答题上失分。最常见的错误包括：写出关于某个主题的所有知识，而不是直接回答问题；在描述研究设计时未能操作化变量；以及忘记与提供的场景联系起来。例如，在关于减少偏见的问题中，学生可能描述了 Sherif 的 Robbers Cave 实验，却忘记了说明在那个特定情境中共同目标是如何被创造出来的。要避免这些陷阱，一定要圈出指令词（描述、解释、设计），并在开篇句呼应问题的措辞。写一个简要计划：陈述你的观点，将其应用于情境，然后用心理学术语展开。这种“观点 – 应用 – 展开”的结构可以将一个平淡的答案提升为清晰、聚焦的回答。

12. Revision Checklist and Final Tips | 复习清单与最后提示

Before your unit test, use this checklist to self-assess your knowledge. For Memory: can you draw and label the multi-store model, explain the primacy and recency effects, and describe a study on forgetting? For Perception: are you able to compare monocular and binocular depth cues, give examples of visual illusions, and evaluate two explanations for one illusion? For Social Influence: can you distinguish compliance, identification, and internalisation, and link situational factors to Milgram’s variations? For Research Methods: do you know how to state a hypothesis, spot ethical issues, and choose an appropriate experimental design? A final tip: practise planning answers aloud, teaching a friend, or creating flashcards. Active retrieval builds the neural pathways that help you recall information under exam pressure.

在你的单元测试之前，用这份清单自我评估知识掌握情况。记忆部分：你能画出并标注多存储模型，解释首因效应和近因效应，并描述一个关于遗忘的研究吗？感知部分：你能比较单眼和双眼深度线索，举例说明视觉错觉，并评估对一种错觉的两种解释吗？社会影响部分：你能区分顺从、认同和内化，并将情境因素与 Milgram 的变化实验联系起来吗？研究方法部分：你知道如何陈述假设、发现伦理问题并选择合适的实验设计吗？最后一条提示：练习口头规划答案、教一个朋友或制作抽认卡。主动提取会构建那些帮助你在考试压力下提取信息的神经通路。
