1. Question 1: Defining Psychology | 题目 1：心理学的定义
Question: Which of the following best defines psychology? A) The study of the brain. B) The study of mental illness. C) The study of the mind and behaviour. D) The study of dreams.
题目：以下哪一项最恰当地定义了心理学？A) 研究大脑的学科。B) 研究心理疾病的学科。C) 研究心智与行为的学科。D) 研究梦境的学科。
The correct answer is C. Psychology is the scientific study of the mind and behaviour. While the brain (A) is studied in biological psychology and mental illness (B) is a topic within clinical psychology, neither fully captures the breadth of the discipline. The study of dreams (D) is only one small area. Psychology encompasses how people think, feel, and act in both normal and unusual situations.
正确答案是 C。心理学是对心智与行为的科学研究。虽然大脑（A）是生物心理学的研究对象，心理疾病（B）是临床心理学的一个主题，但两者都不能涵盖该学科的广度。梦境研究（D）也只是其中一个小领域。心理学涵盖人们在正常与异常情境下的思考、感受与行为方式。
2. Question 2: Independent and Dependent Variables | 题目 2：自变量与因变量
Question: In an experiment, what is the independent variable? A) The variable that is measured. B) The variable that is changed by the researcher. C) The variable that stays the same. D) The variable that is controlled.
题目：在实验中，什么是自变量？A) 被测量的变量。B) 研究者改变的变量。C) 保持不变的变量。D) 被控制的变量。
The correct answer is B. The independent variable (IV) is the factor the experimenter manipulates or changes to see its effect. The variable that is measured is the dependent variable (A). The variables kept constant (C and D) are known as control variables. A clear understanding of IV and DV is essential in designing experiments.
正确答案是 B。自变量（IV）是实验者操控或改变以观察其效果的因素。被测量的变量是因变量（A）。保持恒定的变量（C 和 D）称为控制变量。清晰地理解自变量和因变量是实验设计的基础。
3. Question 3: Identifying Variables in a Scenario | 题目 3：在情境中识别变量
Question: A researcher wants to test if music affects concentration. Which is the independent variable? A) Test scores on a concentration task. B) The type of music played. C) The level of concentration shown. D) The time of day.
题目：一位研究者想测试音乐是否影响注意力。哪一个是自变量？A) 注意力任务的测试分数。B) 播放的音乐类型。C) 表现出的注意力水平。D) 一天中的时间段。
The answer is B. The researcher is deliberately changing the type of music to see if it has an impact. The test scores or level of concentration (A and C) would be the dependent variables, as they are the outcome being measured. Time of day (D) would need to be controlled to prevent it from affecting the results.
答案是 B。研究者有意改变音乐类型以观察其是否有影响。测试分数或注意力水平（A 和 C）会是因变量，因为它们是被测量的结果。时间段（D）需要被控制，以免干扰结果。
4. Question 4: The Multi-Store Model of Memory | 题目 4：记忆的多重储存模型
Question: The model that describes memory as having sensory memory, short-term memory (STM), and long-term memory (LTM) is called the… A) Working memory model. B) Multi-store model. C) Levels of processing model. D) Schema theory.
题目：将记忆描述为包含感觉记忆、短时记忆（STM）和长时记忆（LTM）的模型被称为…… A) 工作记忆模型。B) 多储存模型。C) 加工水平模型。D) 图式理论。
The correct answer is B. The multi-store model (Atkinson & Shiffrin, 1968) proposes three separate stores. Information flows from sensory memory to STM through attention, and then to LTM through rehearsal. The working memory model (A) is a more detailed view of STM. Levels of processing (C) focuses on depth of processing, and schema theory (D) deals with mental frameworks.
正确答案是 B。多储存模型（Atkinson & Shiffrin, 1968）提出三个独立的储存库。信息通过注意从感觉记忆进入短时记忆，再通过复述进入长时记忆。工作记忆模型（A）是对短时记忆更细致的描述。加工水平模型（C）关注加工深度，图式理论（D）探讨心理框架。
5. Question 5: Brain and Memory | 题目 5：大脑与记忆
Question: Which brain structure plays a key role in forming new long-term memories? A) Cerebellum. B) Hippocampus. C) Occipital lobe. D) Brainstem.
题目：哪一脑结构在形成新的长时记忆中起关键作用？A) 小脑。B) 海马体。C) 枕叶。D) 脑干。
The answer is B. The hippocampus, located in the temporal lobe, is crucial for consolidating new memories. Damage to this area can prevent a person from creating new long-term memories. The cerebellum (A) is involved in motor skills, the occipital lobe (C) processes vision, and the brainstem (D) controls basic life functions.
答案是 B。位于颞叶的海马体对巩固新记忆至关重要。若此区域受损，个体将无法形成新的长时记忆。小脑（A）参与运动技能，枕叶（C）处理视觉信息，脑干（D）控制基本生命功能。
6. Question 6: Asch’s Conformity Study | 题目 6：阿希的从众研究
Question: In Asch’s classic conformity experiment, participants were asked to… A) give electric shocks to a learner. B) judge the lengths of lines. C) play the role of a prison guard. D) solve difficult puzzles.
题目：在阿希经典的从众实验中，参与者被要求…… A) 对学习者施行电击。B) 判断线条的长度。C) 扮演监狱看守的角色。D) 解决困难的字谜。
The correct answer is B. Solomon Asch (1951) asked participants to say which of three comparison lines was the same length as a standard line. Confederates gave wrong answers, and many participants conformed to avoid standing out. Option A refers to Milgram’s obedience study, and option C refers to Zimbardo’s prison experiment.
正确答案是 B。Solomon Asch（1951）要求参与者说出三条比较线中哪条与标准线等长。同谋者给出错误答案，许多参与者为了不显得突出而选择从众。选项 A 指米尔格拉姆的服从实验，选项 C 指津巴多的监狱实验。
7. Question 7: Understanding Visual Illusions | 题目 7：理解视觉错觉
Question: What is a visual illusion? A) A correct perception of an image. B) A mistaken or distorted perception of a real stimulus. C) Seeing something that is not there. D) A blurred afterimage.
题目：什么是视觉错觉？A) 对图像的正确知觉。B) 对真实刺激的错误或扭曲知觉。C) 看到并不存在的东西。D) 模糊的残像。
The answer is B. A visual illusion occurs when our brain misinterprets sensory information from a real object, such as the Müller-Lyer illusion. Seeing something that is not there (C) is a hallucination. An afterimage (D) is a lingering sensation after the stimulus is removed. Illusions teach us that perception is an active, constructive process.
答案是 B。当大脑错误解读来自真实物体的感觉信息时，便产生视觉错觉，如缪勒-莱耶错觉。看到不存在的东西（C）是幻觉。残像（D）是刺激移除后仍残留的感觉。错觉告诉我们，知觉是一个主动的、建构的过程。
8. Question 8: Piaget’s Stages of Cognitive Development | 题目 8：皮亚杰的认知发展阶段
Question: According to Piaget, a child in the concrete operational stage (around 7-11 years) is able to… A) think logically about abstract concepts. B) understand conservation of number and volume. C) only explore the world through senses and actions. D) use systematic scientific reasoning.
题目：根据皮亚杰，处于具体运算阶段（约7-11岁）的儿童能够…… A) 对抽象概念进行逻辑思维。B) 理解数量与体积的守恒。C) 只通过感觉和动作探索世界。D) 运用系统的科学推理。
The correct answer is B. In the concrete operational stage, children master conservation (e.g., understanding that water quantity remains the same despite container shape) and learn to think logically about concrete objects. Abstract thinking (A and D) appears in the formal operational stage (11+), while sensory-motor exploration (C) is the first stage (0-2 years).
正确答案是 B。在具体运算阶段，儿童掌握守恒（例如理解无论容器形状如何，水量保持不变），并学会对具体物体进行逻辑思维。抽象思维（A 和 D）出现在形式运算阶段（11岁以上），而感觉运动探索（C）是第一阶段（0-2岁）。
9. Question 9: Types of Observation | 题目 9：观察法的类型
Question: A researcher watches children playing in a public playground without interfering or revealing their presence. This is an example of… A) controlled observation. B) naturalistic observation. C) participant observation. D) a laboratory experiment.
题目：一位研究者在一处公共游乐场观察儿童玩耍，既不干预也不暴露自己的存在。这是…… 的一个例子。A) 控制观察。B) 自然观察。C) 参与观察。D) 实验室实验。
The answer is B. Naturalistic observation involves watching behaviour in a real-world setting without manipulation. Because the researcher does not interfere or take part, it is not participant observation (C). A controlled observation (A) would take place in a structured environment with some variables managed.
答案是 B。自然观察指在自然环境中观察行为而不加操控。因为研究者既不干预也不参与，所以不是参与观察（C）。控制观察（A）则在结构化环境中进行，并对某些变量加以管理。
10. Question 10: Ethical Guidelines | 题目 10：伦理准则
Question: Which of the following is an ethical guideline that researchers must follow? A) Always use a large sample size. B) Obtain informed consent from participants. C) Ensure the study is double-blinded. D) Record all data using a computer.
题目：以下哪一项是研究者必须遵守的伦理准则？A) 总是使用大样本量。B) 获得参与者的知情同意。C) 确保实验是双盲的。D) 使用电脑记录所有数据。
The correct answer is B. Informed consent means participants are told the nature of the study and agree to take part. Large sample size (A) is about methodology, not ethics. Double-blinding (C) is a design to reduce bias, and recording data (D) concerns accuracy, but neither guarantees ethical protection on its own.
正确答案是 B。知情同意意味着参与者被告知研究性质并同意参加。大样本量（A）属于方法学问题而非伦理。双盲设计（C）是为减少偏见，数据记录（D）关乎准确性，但二者本身并不能保证伦理保护。
11. Question 11: Milgram’s Obedience Study | 题目 11：米尔格拉姆的服从实验
Question: In Milgram’s obedience study, participants believed they were… A) completing a personality test. B) generating word associations. C) teaching a learner and delivering electric shocks. D) participating in a debate.
题目：在米尔格拉姆的服从研究中，参与者相信自己在…… A) 完成人格测试。B) 生成词语联想。C) 教一名学习者并实施电击。D) 参加一场辩论。
The answer is C. Stanley Milgram (1963) wanted to understand obedience to authority. Volunteers were told they were giving shocks for wrong answers, although no real shocks were used. The study revealed that ordinary people can follow orders to inflict harm. Options A and B are not related to the study’s cover story.
答案是 C。Stanley Milgram（1963）想了解对权威的服从。志愿者们被告知他们正因错误答案而对学习者施加电击，尽管并未使用真实电击。该研究揭示了普通人会遵从指令造成伤害。选项 A 和 B 与研究背景无关。
12. Question 12: Qualitative and Quantitative Data | 题目 12：定性数据与定量数据
Question: Which of the following is an example of qualitative data? A) The number of times a student raises their hand. B) The average score on a memory test. C) A detailed interview transcript about personal experiences. D) The percentage of people who conformed in an experiment.
题目：以下哪一个是定性数据的例子？A) 学生举手的次数。B) 记忆测试的平均分数。C) 关于个人经历的详细访谈转录。D) 实验中从众者的百分比。
Correct answer is C. Qualitative data is descriptive, non-numerical information such as words, images, or detailed observations. Quantitative data involves numbers and statistics (A, B, D). Both types are valuable in psychology; interviews are a common method for gathering rich, qualitative data.
正确答案是 C。定性数据是描述性、非数值的信息，例如文字、图像或详细观察。定量数据涉及数字和统计（A、B、D）。两种类型在心理学中都有价值；访谈是收集丰富定性数据的常用方法。
