1. Question 1: Defining Psychology | 第1题:心理学定义
Question: Which of the following best describes psychology?
A) The study of the brain
B) The scientific study of mind and behaviour
C) The treatment of mental illness
D) The analysis of dreams
问题: 以下哪项最恰当地描述了心理学?
A) 研究大脑
B) 对心理和行为的科学研究
C) 治疗心理疾病
D) 分析梦境
Answer: B – Psychology is defined as the scientific study of the mind and behaviour. It uses systematic methods, such as experiments and observations, to gather evidence.
答案:B – 心理学被定义为对心理和行为的科学研究。它使用实验和观察等系统方法来收集证据。
Why the others are wrong: Option A is too narrow – studying the brain is part of biological psychology or neuroscience, but psychology also includes thoughts, emotions, and social behaviour. Option C describes a clinical application, not the definition of the whole field. Option D focuses only on one early Freudian technique and does not represent modern psychology.
其他选项错误原因: 选项 A 过于狭隘——研究大脑是生物心理学或神经科学的一部分,但心理学还包括思维、情绪和社会行为。选项 C 描述的是一种临床应用,而不是整个学科的定义。选项 D 只关注早期弗洛伊德的一种技术,不能代表现代心理学。
2. Question 2: Duration of Short-Term Memory | 第2题:短时记忆的持续时间
Question: Approximately how long does information stay in short-term memory without rehearsal?
A) A few seconds to around 30 seconds
B) About one hour
C) Up to one day
D) It is stored permanently
问题: 在没有复述的情况下,信息在短时记忆中大约能保持多久?
A) 几秒钟到大约 30 秒
B) 大约一小时
C) 长达一天
D) 永久存储
Answer: A – Research by Peterson and Peterson (1959) showed that without rehearsal, short-term memory lasts roughly 18–30 seconds. If you repeat the information, you can keep it active for longer.
答案:A – Peterson 和 Peterson (1959) 的研究表明,不复述的话,短时记忆大约持续 18 到 30 秒。如果你重复信息,就能保持更长时间。
Key idea: The multi-store model of memory describes short-term memory as a temporary store with limited capacity (7±2 chunks). Rehearsal is the process that transfers information to long-term memory.
核心概念: 记忆的多重储存模型将短时记忆描述为一个容量有限(7±2 个组块)的临时储存库。复述是将信息转移到长时记忆的过程。
3. Question 3: Ethical Principle – Informed Consent | 第3题:伦理原则——知情同意
Question: Before taking part in a psychological study, what must a researcher usually obtain from participants?
A) Informed consent
B) A payment receipt
C) A signature on a blank form
D) A guarantee of the results
问题: 在参与心理学研究之前,研究者通常必须从参与者那里获得什么?
A) 知情同意
B) 付款收据
C) 空白表格上的签名
D) 结果的保证
Answer: A – Informed consent means that participants are told the aim of the study, what they will be asked to do, and their right to withdraw at any time, before they agree to take part.
答案:A – 知情同意意味着在参与者同意参加之前,要告知他们研究的目的、他们需要做什么以及他们有权随时退出。
Why this matters: The British Psychological Society (BPS) ethical guidelines require informed consent to protect participants from harm and to respect their autonomy. For those under 16, parental consent is also needed.
为什么这一点重要: 英国心理学会 (BPS) 的伦理准则要求知情同意,以保护参与者免受伤害并尊重他们的自主权。对于 16 岁以下的人,还需要父母同意。
4. Question 4: Visual Illusion – Müller-Lyer | 第4题:视错觉——缪勒-莱尔
Question: In the Müller-Lyer illusion, which line appears longer?
A) The line with arrowheads pointing outwards
B) The line with arrowheads pointing inwards
C) Both lines appear exactly the same length
问题: 在缪勒-莱尔错觉中,哪条线看起来更长?
A) 箭头朝外的线
B) 箭头朝内的线
C) 两条线看起来完全一样长
Answer: B – The line with inward-pointing arrowheads (the ‘fins’ pointing inwards, like >—<) looks longer, even though both horizontal lines are identical in length.
答案:B – 箭头朝内的线(翼片向内,如 >—<)看起来更长,尽管两条水平线的长度完全相同。
Explanation: One theory is that we interpret the arrows as depth cues. The outward-pointing fins resemble the corner of a room viewed from inside (closer), while inward-pointing fins resemble the corner of a building viewed from outside (farther away). The brain judges the ‘farther’ line as physically longer to produce the same retinal image size.
解释: 一种理论认为,我们将箭头解释为深度线索。朝外的翼片像从内部看到的房间角落(较近),而朝内的翼片像从外部看到的建筑物拐角(较远)。大脑会判断“更远”的线条在物理上更长,才能在视网膜上形成相同大小的图像。
5. Question 5: Independent and Dependent Variables | 第5题:自变量和因变量
Question: Explain what is meant by an independent variable (IV) and a dependent variable (DV) in an experiment. Give an example to support your answer.
问题: 解释实验中自变量 (IV) 和因变量 (DV) 的含义。举例支持你的回答。
Model Answer: The independent variable is the factor the researcher changes or manipulates. The dependent variable is the factor the researcher measures; it depends on the IV. For example, in an experiment to test whether background music affects concentration scores, the IV would be the type of music (or silence) and the DV would be the score on a concentration test.
标准答案: 自变量是研究者改变或操纵的因素。因变量是研究者测量的因素;它取决于自变量。例如,在一个测试背景音乐是否影响注意力分数的实验中,自变量是音乐的类型(或安静条件),因变量是注意力测试的分数。
Common mistake to avoid: Do not simply say the IV is the ’cause’ and the DV is the ‘effect’. Always identify what is being changed and what is being measured in clear terms. Use the exact wording from the scenario if one is given.
要避免的常见错误: 不要简单地说 IV 是“原因”,DV 是“结果”。始终用清晰的语言指出被改变的是什么,被测量的是什么。如果有情境描述,就使用其中的确切措辞。
6. Question 6: Writing a Testable Hypothesis | 第6题:写出可检验的假设
Question: A researcher wants to investigate whether the number of hours of sleep affects memory performance. Write a suitable hypothesis for this study.
问题: 一位研究者想调查睡眠时长是否影响记忆表现。为这项研究写出一个合适的假设。
Model Hypothesis: ‘Students who sleep for 8 hours the night before a memory test will recall significantly more words from a list than students who sleep for only 4 hours.’
假设范例: “在记忆测试前一晚睡了 8 小时的学生,会比只睡 4 小时的学生回想出显著更多的单词。”
How to structure a good hypothesis: It should mention both conditions of the IV (8 hours vs. 4 hours sleep), specify the DV (number of words recalled), and state a clear, directional prediction. The hypothesis must be testable and include operationalised variables – that means all terms are measurable.
如何构建好的假设: 它应该提及 IV 的两种条件(8 小时睡眠对 4 小时睡眠),明确指出 DV(回忆出的单词数量),并做出清晰、有方向的预测。假设必须是可检验的,并且包含可操作化的变量——这意味着所有术语都是可测量的。
7. Question 7: Piaget’s Concrete Operational Stage | 第7题:皮亚杰的具体运算阶段
Question: Briefly describe one cognitive ability that children develop during Piaget’s concrete operational stage (around 7–11 years). Provide an example.
问题: 简要描述儿童在皮亚杰的具体运算阶段(大约 7–11 岁)发展出的一种认知能力。提供一个例子。
Suggested Answer – Conservation: During the concrete operational stage, children grasp the principle of conservation – the understanding that quantity remains the same even when appearance changes. For instance, if you pour water from a short, wide beaker into a tall, thin beaker, a child in this stage will say the amount of water is still the same because no water has been added or removed.
建议答案——守恒: 在具体运算阶段,儿童掌握了守恒原则——即理解尽管外观发生变化,数量依然保持不变。例如,如果你把水从一个矮宽的烧杯倒入一个高细的烧杯,处于这个阶段的儿童会说水量仍然一样,因为没有添加或移走水。
Other possible answers: Classification (grouping objects into categories), seriation (ordering objects by size), or reversibility (understanding that actions can be reversed). Always link the ability to a concrete example; marks are often lost by just naming the concept without explanation.
其他可能的答案: 分类(将物体分组)、排序(按大小排列物体)或可逆性(理解动作可以逆转)。始终结合具体例子来解释这一能力;很多失分都是因为只说出概念名称而缺乏解释。
8. Question 8: Conformity – Asch’s Study | 第8题:从众——阿希的研究
Question: Describe one key finding from Asch’s (1951) line-judgement study on conformity. What does this tell us about social influence?
问题: 描述阿希 (1951) 线条判断从众研究的一个关键发现。这告诉我们关于社会影响的什么?
Model Answer: Asch found that about 75% of participants conformed to the group’s wrong answer at least once, even when the correct answer was obvious. The average conformity rate across all trials was around 37%. This shows that people may go along with a group norm even when they privately disagree, a phenomenon called normative social influence.
标准答案: 阿希发现大约 75% 的参与者至少顺从了一次集体的错误答案,即使正确答案非常明显。所有试次中的平均从众率约为 37%。这表明即使私下并不同意,人们也可能会顺从团体规范,这种现象称为规范性的社会影响。
Extension point: When one other person (a dissenter) gave the correct answer, conformity dropped sharply. This highlights the power of social support in resisting pressure to conform.
拓展点: 当有另一个人(异议者)给出正确答案时,从众率急剧下降。这凸显了社会支持在抵抗从众压力方面的力量。
9. Question 9: Designing an Experiment – Music and Memory | 第9题:设计实验——音乐与记忆
Question: Design a simple experiment to test the effect of listening to music on short-term memory for a list of words. You should identify: the hypothesis, IV and DV, one control variable, and a brief procedure. Also mention one ethical consideration.
问题: 设计一个简单实验,测试听音乐对单词表短时记忆的影响。你应明确:假设、IV 和 DV、一个控制变量、简要步骤,并提及一项伦理考量。
Worked design: Hypothesis: ‘Participants who learn a word list while listening to instrumental music will recall fewer words than those who learn in silence.’ IV: presence of music (music vs. silence). DV: number of words correctly recalled. Control: all participants hear the same word list, same volume, and get the same amount of study time (2 minutes). Procedure: Randomly allocate 20 students to either the music or silence group. Present 15 words on a screen for 2 minutes. Immediately after, give a 1-minute written recall test. Compare the recall scores. Ethical consideration: obtain informed consent and debrief participants afterwards, explaining the true purpose of the study.
设计范例: 假设:“听器乐音乐学习单词表的参与者,会比在安静条件下学习的参与者回忆更少的单词。” IV:音乐的有无(音乐 vs 安静)。DV:正确回忆的单词数量。控制:所有参与者听到相同的单词表、相同的音量,并获得相同的学习时间(2 分钟)。步骤:将 20 名学生随机分配至音乐组或安静组。在屏幕上呈现 15 个单词 2 分钟。学习后立即进行 1 分钟的书面回忆测试。比较回忆分数。伦理考量:获得知情同意,并在实验结束后向参与者解释研究的真实目的(事后解说)。
Marking focus: In this type of question, examiners look for operationalised variables (clearly measurable), a practical procedure, and suitable ethical reference. Mentioning random allocation earns extra marks because it helps control participant variables.
评分重点: 在此类题目中,考官看重可操作化的变量(清晰可测)、可行的步骤和恰当的伦理提及。提到随机分配可获额外加分,因为它有助于控制参与者变量。
10. Question 10: Evaluating the Case Study Method | 第10题:评估案例研究方法
Question: Evaluate one strength and one weakness of using a case study as a research method in psychology. Use an example to illustrate your points.
问题: 评估在心理学中使用案例研究作为研究方法的一个优点和一个缺点。举例说明你的观点。
Strength: A case study provides rich, in-depth detail about a single individual or small group, which can give unique insights. For example, the case of HM, who lost the ability to form new memories after brain surgery, revolutionised our understanding of different memory systems. This depth would be impossible to obtain through a survey.
优点: 案例研究可以提供关于单个个体或小群体的丰富、深入细节,从而带来独特见解。例如,HM 的案例——他在脑部手术后丧失了形成新记忆的能力,彻底改变了我们对不同记忆系统的理解。这种深度是通过调查无法获得的。
Weakness: However, case studies are difficult to generalise because the sample is so small. The findings from HM might not apply to other people with memory impairments, as his damage was specific to the hippocampus. There is also a risk of researcher bias, where the investigator may interpret information subjectively.
缺点: 然而,案例研究难以推广,因为样本太小。来自 HM 的研究结果可能不适用于其他记忆障碍者,因为他的损伤特异地发生在海马体。此外还存在研究者偏差的风险,即研究者可能会主观地解读信息。
Revision tip: Whenever you evaluate a method, link it to a specific psychological example – this shows application and secures higher marks.
复习提示: 每当你评估一种方法时,要联系具体的心理学实例——这能体现应用能力,确保获得更高分数。
11. Question 11: Data Analysis – Mean and Range | 第11题:数据分析——平均值与极差
Question: A researcher records the following recall scores in a memory test: 8, 10, 12, 9, 11. Calculate the mean and the range of these scores. Explain why these descriptive statistics are useful.
问题: 一位研究者记录了记忆测试中的以下回忆分数:8, 10, 12, 9, 11。计算这些分数的平均值和极差。解释为什么这些描述统计量是有用的。
Answer: Mean = (8 + 10 + 12 + 9 + 11) ÷ 5 = 50 ÷ 5 = 10. Range = highest score – lowest score = 12 – 8 = 4. The mean tells us the central tendency of the data – the typical recall score. The range gives a simple measure of spread or variability, showing how consistent the scores are.
答案: 平均值 = (8 + 10 + 12 + 9 + 11) ÷ 5 = 50 ÷ 5 = 10。极差 = 最高分 – 最低分 = 12 – 8 = 4。平均值告诉我们数据的集中趋势——典型的回忆分数。极差则提供了一个分散或变异性的简单度量,显示分数的波动大小。
Why this matters: In Year 7, you are expected to perform basic calculations and understand that the mean can be affected by extreme outliers. The range is a quick way to check for consistency, but it does not tell you about the pattern of results between the extremes.
为什么重要: 在 7 年级,你需要进行基本计算,并理解平均值可能受极端离群值的影响。极差是检查一致性的快速方法,但它不能告诉你极值之间的结果分布模式。
12. Question 12: Evaluation – Improving the Study | 第12题:评估——改进研究
Question: A class conducted a memory experiment with only 10 participants, who were all the researchers’ best friends. Suggest two improvements to the study and explain why each improvement makes the findings more trustworthy.
问题: 一个班级进行了一项记忆实验,只有 10 名参与者,并且全都是研究者最好的朋友。提出两项改进建议,并解释每项改进如何使研究结果更可信。
Improvement 1: Use a larger sample size, for example 30 participants. A larger sample reduces the impact of unusual individual scores (anomalies) and makes it easier to detect a genuine effect, increasing the reliability of the findings.
改进 1: 使用更大的样本量,例如 30 名参与者。较大的样本可以减少异常个体分数的影响,更容易发现真实效应,从而提高研究结果的信度。
Improvement 2: Recruit participants who are not friends with the researchers, and use random sampling if possible. This reduces investigator effects and participant bias – friends may try harder, or ‘demand characteristics’ may lead them to guess the aim and change their behaviour. Having naive participants increases the objectivity of the study.
改进 2: 招募不是研究者朋友的参与者,并尽可能使用随机抽样。这可以减少研究者效应和参与者偏差——朋友可能会更努力,或者“需求特征”会导致他们猜测目的并改变行为。使用不知情的参与者能增加研究的客观性。
Common phrasing in mark schemes: Look for words like ‘validity’, ‘reliability’, ‘generalisability’, and ‘control’. Even in Year 7, using these terms—with a brief explanation—will raise your answer to a higher level.
评分方案中的常见用语: 寻找诸如“效度”、“信度”、“推广性”和“控制”等词汇。即使在 7 年级,使用这些术语——并附上简短解释——也能将你的答案提升到更高水平。
