2. Multiple-Choice Questions: Psychology Foundations & Research Methods | 选择题：心理学基础与研究方法
Question 1: Which of the following best defines psychology?
- A) The study of the brain and its diseases
- B) The scientific study of behaviour and mental processes
- C) The practice of counselling and therapy
- D) The analysis of dreams and the unconscious mind
问题1：以下哪项最准确地定义了心理学？
- A) 对大脑及其疾病的研究
- B) 对行为与心理过程的科学研究
- C) 咨询与治疗的实践
- D) 对梦和无意识心理的分析
Answer and Explanation: The correct answer is B. Psychology is defined as the scientific study of behaviour and mental processes. Option A refers to neuroscience or neurology, option C is a common misconception that limits psychology to clinical practice, and option D describes a psychoanalytic approach, which is only one part of psychology’s history.
答案与解释：正确答案是 B。心理学被定义为对行为与心理过程的科学研究。选项 A 指的是神经科学或神经学，选项 C 是一种常见误解，将心理学局限为临床实践，选项 D 描述的是精神分析取向，它只是心理学历史中的一部分。
Question 2: In an experiment, the variable that the researcher manipulates is called the:
- A) Dependent variable
- B) Confounding variable
- C) Independent variable
- D) Controlled variable
问题2：在实验中，研究者操纵的变量被称为：
- A) 因变量
- B) 混淆变量
- C) 自变量
- D) 控制变量
Answer and Explanation: The correct answer is C. The independent variable (IV) is the one deliberately changed by the experimenter to observe its effect on the dependent variable (DV). The DV is what is measured, while controlled variables are kept constant to ensure a fair test.
答案与解释：正确答案是 C。自变量（IV）是实验者有意改变的变量，以观察其对因变量（DV）的影响。因变量是被测量的量，而控制变量则保持恒定以确保公平测试。
3. Multiple-Choice Questions: Memory Models | 选择题：记忆模型
Question 3: According to the Atkinson-Shiffrin model, the three memory stores are:
- A) Sensory, short-term, and long-term memory
- B) Visual, auditory, and semantic memory
- C) Explicit, implicit, and procedural memory
- D) Episodic, semantic, and working memory
问题3：根据阿特金森-谢夫林模型，三种记忆储存是：
- A) 感觉记忆、短时记忆和长时记忆
- B) 视觉记忆、听觉记忆和语义记忆
- C) 外显记忆、内隐记忆和程序性记忆
- D) 情景记忆、语义记忆和工作记忆
Answer and Explanation: The correct answer is A. The Atkinson-Shiffrin (multi-store) model proposes that information flows through sensory memory, then into short-term memory (STM) with limited capacity, and finally into long-term memory (LTM) for durable storage. Options B, C, and D refer to other classifications of memory or alternative models.
答案与解释：正确答案是 A。阿特金森-谢夫林（多储存）模型提出，信息流经感觉记忆，然后进入容量有限的短时记忆，最后进入长时记忆进行持久存储。选项 B、C、D 指的是记忆的其他分类或替代模型。
Question 4: The typical capacity of short-term memory is about:
- A) 3 items
- B) 5 items
- C) 7 ± 2 chunks
- D) Unlimited
问题4：短时记忆的典型容量约为：
- A) 3 个项目
- B) 5 个项目
- C) 7 ± 2 个组块
- D) 无限
Answer and Explanation: The correct answer is C. Miller (1956) found that the span of STM is approximately 7 plus or minus 2 chunks. A chunk can be a digit, a letter, or a meaningful unit. Long-term memory, by contrast, is considered to have unlimited capacity.
答案与解释：正确答案是 C。米勒（1956）发现短时记忆的广度大约为 7 ± 2 个组块。一个组块可以是一个数字、一个字母或一个有意义的单元。相比之下，长时记忆被认为是容量无限的。
4. Multiple-Choice Questions: Social Influence and Long-Term Memory | 选择题：社会影响与长时记忆
Question 5: Which of the following is an example of long-term memory?
- A) Remembering a phone number just given to you for a few seconds
- B) The afterimage of a bright light you have just seen
- C) Knowing the name of your first primary school teacher
- D) Hearing an echo of a sound milliseconds after it stopped
问题5：以下哪项是长时记忆的例子？
- A) 刚刚听到的电话号码在几秒钟内记得
- B) 刚刚看到的强光留下的残像
- C) 知道你的第一位小学老师的名字
- D) 声音停止后几毫秒内听到的回声
Answer and Explanation: The correct answer is C. Knowing your first teacher’s name is information stored over a long period, which relies on long-term memory. A and D refer to short-term and sensory memory respectively, while B relates to iconic sensory memory.
答案与解释：正确答案是 C。知道第一位老师的名字是长时间存储的信息，它依赖于长时记忆。A 和 D 分别指短时记忆和感觉记忆，B 与图像感觉记忆有关。
Question 6: In Asch’s classic conformity study, approximately what percentage of participants conformed to the incorrect majority at least once?
- A) 20%
- B) 37%
- C) 75%
- D) 95%
问题6：在阿希的经典从众研究中，大约有多少百分比的参与者在至少一次试验中跟随了错误的大多数？
- A) 20%
- B) 37%
- C) 75%
- D) 95%
Answer and Explanation: The correct answer is C. Asch found that about 75% of participants conformed to the clearly wrong majority judgement at least once. This high conformity rate demonstrated the power of social pressure, even when the correct answer was obvious.
答案与解释：正确答案是 C。阿希发现大约 75% 的参与者在至少一次试验中屈服于明显错误的大多数判断。如此高的从众比例证明了社会压力的威力，即便正确答案显而易见。
5. Short-Answer Question 1: Differentiating Memory Types | 简答题1：区分记忆类型
Question: Explain the main differences between short-term memory and long-term memory. Provide one example for each. (4 marks)
问题：解释短时记忆与长时记忆之间的主要区别。各提供一个例子。（4分）
Model Answer: apacity of around 7 ± 2 chunks and stores information for a brief duration (up to about 18– limited capacity and can store information for a very long time, perhaps a lifetime. For example, recalling the events of your last birthday party.
参考答案：短时记忆的容量非常有限，约为 7 ± 2 个组块，信息储存时间短暂（若无复述最多约 18–30 秒）。例如，记住一个新电话号码仅够拨出它。长时记忆的容量可能是无限的，信息可以储存很长时间，甚至是一生。例如，回想起你上一个生日派对的情景。
For full marks, you need: 1 mark for stating the limited capacity of STM, 1 mark for the brief duration of STM, 1 mark for stating the large/unlimited capacity and long duration of LTM, and 1 mark for appropriate, clear examples for both. Simply listing bullet points without linking capacity and duration to the correct memory store is a common error.
要拿到满分，你需要：1 分指出 STM 的有限容量，1 分指出 STM 的短暂持续时间，1 分指出 LTM 的大容量或无限容量和长持续时间，1 分给出两者恰当、清晰的例子。常见错误是仅仅列出要点，但没有将容量和持续时间对应到正确的记忆储存。
6. Short-Answer Question 2: Conformity and Asch | 简答题2：从众与阿希实验
Question: Define the term 'conformity' and outline the key findings of Asch’s line judgement study. (4 marks)
问题：定义‘从众’一词并概述阿希线段判断研究的主要发现。（4分）
Model Answer: Conformity is a change in a person’s behaviour or beliefs as a result of real or imagined group pressure. Asch (1951) conducted a study where participants were asked to match the length of a target line with three comparison lines. In a group of confederates who all gave the same wrong answer, about 75% of genuine participants conformed at least once. Overall, participants agreed with the wrong majority on about 37% of critical trials. This shows that even in an unambiguous task, people may go along with the group to avoid standing out.
参考答案：从众是指一个人的行为或信念因真实或想象的群体压力而发生改变。阿希（1951）进行了一项研究，参与者被要求将目标线段的长度与三条比较线进行匹配。在一群所有给出相同错误答案的实验同谋中，约有 75% 的真实参与者至少从众过一次。总体来看，参与者在关键试次中同意错误大多数的比例约为 37%。这表明，即使任务没有歧义，人们也可能随大流以免显得与众不同。
Marks are awarded for a clear definition of conformity (1 mark), identification of the method (line judgement with confederates, 1 mark), and accurate reporting of the two key statistics (1 mark each). Avoid vague phrases like ‘many people followed the group’: be precise with the numbers 75% and 37%.
评分依据：明确定义从众（1分），指出方法（有同谋的线段判断，1分），准确报告两个关键统计数据（各1分）。避免使用诸如‘很多人跟随群体’等模糊表达，要精确写出 75% 和 37% 这两个数字。
7. Experimental Design Question: Noise and Recall | 实验设计题：噪音与回忆
Question: Design a simple experiment to investigate whether background noise affects word recall. You must identify the independent variable, the dependent variable, and suggest one control variable. (6 marks)
问题：设计一个简单的实验，考察背景噪音是否影响单词回忆。你必须指出自变量、因变量，并建议一个控制变量。（6分）
Model Answer: Aim: To test if background noise impairs recall of a word list. The independent variable (IV) would be the presence or absence of background noise: one group learns and recalls words while a radio plays at a constant volume, and the other group works in silence. The dependent variable (DV) would be the number of words correctly recalled from a list of 20 words after a two-minute distraction task. A key control variable is the difficulty and length of the word list, which must be identical for both groups. Standardised instructions and the same time allowed for learning (e.g., 60 seconds) should also be controlled. This design allows a clear comparison between the two conditions.
参考答案：目的：测试背景噪音是否影响单词列表的回忆。自变量为背景噪音的有无：一组在收音机以恒定音量播放时学习和回忆单词，另一组在安静环境中进行。因变量为经过两分钟的分心任务后，从包含 20 个单词的列表中正确回忆出的单词数量。一个关键的控制变量是单词列表的难度和长度，两组必须完全相同。还应该控制标准化的指导语和相同的学习时间（例如 60 秒）。该设计可对两种条件进行清晰比较。
Marking scheme: 1 mark for stating a clear aim, 1 mark for correctly identifying the IV and its two conditions, 1 mark for a measurable DV, 1 mark for an appropriate control variable with justification, 1 mark for brief procedural details, and 1 mark for overall coherence. A common pitfall is forgetting to make the IV truly ‘manipulated’ with at least two levels, or suggesting a control variable that is not actually held constant.
评分方案：清晰说明目的得 1 分，正确指出自变量及其两个水平得 1 分，列出可测量的因变量得 1 分，给出恰当且有理有据的控制变量得 1 分，简述程序细节得 1 分，整体逻辑连贯得 1 分。常见错误是忘记让自变量真正‘被操纵’并至少有两个水平，或提出一个实际上并未保持恒定的控制变量。
8. Common Mistakes on the Year 8 Psychology Test | S2 心理学测试常见错误
is what you change, the DV is what you measure. Another frequent mistake is quoting the 37% ty rate as the total number of participants who conformed, rather than recognising that 75% conformed at least once but only 37% individual trials showed conformity. Also, when explaining memory capacity, avoid writing '7 items' when the correct phrase is '7 ± 2 chunks'.
许多学生因颠倒自变量和因变量而失分。记住：自变量是你改变的，因变量是你测量的。另一个常见错误是把 37% 的从众率记为从众的参与者总数，却未认识到 75% 的人至少从众过一次，而 37% 反映的是单次试次的从众比例。此外，解释记忆容量时，不要写成‘7个项目’，正确的说法是‘7 ± 2 个组块’。
On short-answer questions, bullet points without full sentences can cost you marks if the question says ‘explain’. Always link concepts to concrete examples. For experimental design, failing to specify how the DV will be recorded (e.g., ‘number of words recalled’ rather than just
