1. Mock Exam Paper Structure & Tips | 模拟试卷结构与答题技巧

The mock paper contains 10 questions worth a total of 30 marks, to be completed in 45 minutes. It includes multiple‑choice items, short‑answer questions (1–2 marks), and one extended‑response question (4 marks) based on a classic psychological study. The topics are selected from the Edexcel Year 7 specification: introduction to psychology, memory, social influence, brain and neuropsychology, developmental psychology, and psychological problems. The balance of question types mirrors the style you will meet in real assessments.

模拟卷共10道题，满分30分，建议45分钟内完成。题型包括选择题、简答题（1—2分）以及一道基于经典心理学研究的扩展回答题（4分）。所有题目选自爱德思Year 7课程大纲：心理学导论、记忆、社会影响、大脑与神经心理学、发展心理学和心理问题。题型配比与实际评测风格一致。

Exam tips: Always read the question stem carefully—command words like “state”, “explain”, or “describe” signal different expectations. Use specialist vocabulary (e.g., “independent variable”, “conformity”, “semantic encoding”) correctly. For extended responses, plan your answer around the cues “aim, method, results, conclusion”. Show your working and, where helpful, link back to psychological theories.

答题技巧：仔细审读题干——”state”（陈述）、”explain”（解释）、”describe”（描述）等指令词对应不同的答题要求。正确使用心理学专有名词（如 “独立变量”、”从众”、”语义编码”）。面对扩展题，按 “目的、方法、结果、结论” 的线索组织答案。写下你的思考过程，并在合适时联系心理学理论。

2. Question 1 – Independent and Dependent Variables | 第1题 – 自变量与因变量

Question: In a study investigating whether listening to music affects concentration, the researcher changes the type of music between groups. Which of the following is the independent variable? A) The number of puzzles solved, B) The type of music played, C) The age of participants, D) The time of day testing occurs. Explanation: The independent variable (IV) is the factor manipulated or changed by the experimenter. Here, the researcher deliberately alters the type of music, making B the IV. The number of puzzles solved (A) is the dependent variable (DV)—the outcome measured. Age and time of day may be extraneous variables that should be controlled.

题目：在一项研究音乐是否影响专注力的实验中，研究者改变不同小组听到的音乐类型。以下哪一项是自变量？A) 解出的谜题数量，B) 播放的音乐类型，C) 参与者年龄，D) 测试发生的时间段。解析：自变量（IV）是实验者操纵或改变的因素。在此研究中，研究者有意改变了音乐类型，因此 B 是自变量。解出的谜题数量（A）是因变量——被测量的结果。年龄和时间段则是应加以控制的额外变量。

3. Question 2 – Memory: Types of Encoding | 第2题 – 记忆：编码类型

Question: Which type of encoding involves processing the meaning of information? A) Acoustic encoding, B) Visual encoding, C) Semantic encoding, D) Tactile encoding. Explanation: Semantic encoding refers to transforming information into a format based on its meaning. It is a deeper form of processing compared with acoustic encoding (processing by sound) or visual encoding (processing by appearance). Studies by Craik and Lockhart (1972) suggested that semantic processing leads to longer‑lasting memories. The correct answer is C.

题目：哪类编码涉及对信息含义的加工？A) 声学编码，B) 视觉编码，C) 语义编码，D) 触觉编码。解析：语义编码指的是将信息转化为基于含义的形式。与声学编码（按声音加工）或视觉编码（按外观加工）相比，这是一种更深层的加工。Craik和Lockhart（1972）的研究表明，语义加工能形成更持久的记忆。正确答案为C。

4. Question 3 – Social Influence: Asch’s Conformity Study | 第3题 – 社会影响：阿希从众实验

Question: State the percentage of participants who conformed at least once in Asch’s original line‑judgement study. (1 mark) Explanation: In Solomon Asch’s (1951) classic experiment, 75% of real participants conformed to the incorrect majority on at least one trial. Overall, participants gave wrong answers about 37% of the time when under group pressure. The study demonstrated the power of normative social influence—people often go along with the group to be accepted, even when they know the group is wrong. Key terms: conformity, majority influence, unanimous group.

题目：陈述在阿希最初的线段判断实验中，至少服从过一次的参与者所占的百分比。（1分）解析：在Solomon Asch（1951）的经典实验中，75%的真实参与者在至少一次试验中服从了错误的大多数。总体而言，在群体压力下参与者给出错误答案的比例约占37%。该研究展示了规范性社会影响的力量——人们为了被接纳往往会随大流，即使他们明知群体是错的。关键术语：从众、多数影响、一致群体。

5. Question 4 – Brain and Neuropsychology: Localisation of Function | 第4题 – 大脑与神经心理学：功能定位

Question: Which lobe of the cerebral cortex is primarily responsible for processing visual information? A) Frontal lobe, B) Temporal lobe, C) Parietal lobe, D) Occipital lobe. Explanation: The occipital lobe, located at the back of the brain, contains the visual cortex. This area receives signals from the eyes and interprets colour, shape, and movement. Damage to the occipital lobe can cause visual agnosia or blindness, even if the eyes are healthy. The frontal lobe handles reasoning and motor control; the temporal lobe processes auditory input and memory; the parietal lobe integrates sensory information.

题目：大脑皮层的哪个叶主要负责处理视觉信息？A) 额叶，B) 颞叶，C) 顶叶，D) 枕叶。解析：枕叶位于大脑后部，包含视觉皮层。该区域接收来自双眼的信号，并解读颜色、形状和运动。枕叶损伤可导致视觉失认或失明，即便眼睛本身是健康的。额叶负责推理和运动控制；颞叶处理听觉输入和记忆；顶叶整合感觉信息。正确答案为D。

6. Question 5 – Piaget’s Stages of Cognitive Development | 第5题 – 皮亚杰认知发展阶段

Question: Choose the correct developmental sequence according to Piaget. A) Sensorimotor → Preoperational → Concrete operational → Formal operational, B) Preoperational → Sensorimotor → Formal operational → Concrete operational, C) Concrete operational → Preoperational → Sensorimotor → Formal operational, D) Formal operational → Concrete operational → Preoperational → Sensorimotor. Explanation: Jean Piaget proposed four invariant stages through which all children pass. The first stage, sensorimotor (0‑2 years), involves learning through senses and actions. The preoperational stage (2‑7 years) sees the growth of symbolic thought but lacks logical reasoning. Concrete operational (7‑11 years) brings logical thinking about tangible objects, while formal operational (12+ years) allows abstract, hypothetical thinking. A presents the correct order.

题目：根据皮亚杰理论，选择正确的发展序列。A) 感知运动 → 前运算 → 具体运算 → 形式运算，B) 前运算 → 感知运动 → 形式运算 → 具体运算，C) 具体运算 → 前运算 → 感知运动 → 形式运算，D) 形式运算 → 具体运算 → 前运算 → 感知运动。解析：皮亚杰提出四个不变的阶段，所有儿童都依此发展。第一阶段感知运动期（0—2岁），通过感官和动作学习；前运算阶段（2—7岁）发展符号思维但缺乏逻辑推理；具体运算阶段（7—11岁）能对具体事物进行逻辑思考；形式运算阶段（12岁以上）能够进行抽象、假设性思维。A为正确顺序。

7. Question 6 – Psychological Problems: Specific Phobias | 第6题 – 心理问题：特定恐惧症

Question: Explain one behavioural symptom of a specific phobia. (2 marks) Explanation: A specific phobia is an anxiety disorder characterised by an excessive, persistent fear of a particular object or situation. A common behavioural symptom is avoidance—the person goes to great lengths to stay away from the feared stimulus. For example, someone with arachnophobia might refuse to enter a room where a spider has been seen. Another symptom is panic, which may include running away, freezing, or clinging to others. These behaviours interfere with normal daily life.

题目：解释特定恐惧症的一种行为症状。（2分）解析：特定恐惧症是一种焦虑障碍，表现为对某一特定物体或情境的过度、持续恐惧。一种常见的行为症状是回避——个体极力避免接触恐惧刺激。例如，患有蜘蛛恐惧症的人可能拒绝进入曾见过蜘蛛的房间。另一症状是恐慌，可能表现为逃跑、僵住或紧抓他人。这些行为会干扰正常的日常生活。

8. Question 7 – Research Methods: Sampling Techniques | 第7题 – 研究方法：抽样技术

Question: A psychologist selects every 8th name on a school register to take part in a survey. What is the name of this sampling method? A) Random sampling, B) Systematic sampling, C) Opportunity sampling, D) Stratified sampling. Explanation: Systematic sampling involves choosing participants according to a fixed rule or interval from a list, such as every 8th name. It is quicker than true random sampling but still gives an evenly spread sample. In contrast, opportunity sampling selects whoever is available at the time, and stratified sampling splits the population into subgroups first. The correct answer is B.

题目：一位心理学家从学校花名册上每隔8人选择一名参加问卷调查。这种抽样方法叫什么？A) 随机抽样，B) 系统抽样，C) 便利抽样，D) 分层抽样。解析：系统抽样指根据固定规则或间隔从名单中选取参与者，如每隔8人。它比真正的随机抽样省时，但仍能提供分布均匀的样本。相比之下，便利抽样选择当时方便接触的人，分层抽样则先按子群体划分。正确答案为B。

9. Question 8 – Data Handling: Correlation Coefficients | 第8题 – 数据处理：相关系数

Question: Which of the following correlation coefficients indicates the strongest negative relationship between two variables? A) -0.92, B) -0.11, C) +0.85, D) 0.00. Explanation: A correlation coefficient ranges from -1 to +1. The sign indicates direction: negative means as one variable increases, the other tends to decrease. The strength is shown by the absolute value—the closer to 1 (ignoring sign), the stronger the relationship. -0.92 is very close to -1 and therefore shows a strong negative correlation. -0.11 is weak negative, +0.85 is strong positive, and 0.00 means no correlation. The answer is A.

题目：以下哪个相关系数表示两个变量之间最强的负相关关系？A) -0.92, B) -0.11, C) +0.85, D) 0.00。解析：相关系数取值范围从 -1 到 +1。符号表示方向：负数表示一个变量增大时，另一个趋向减小。强度由绝对值体现——越接近1（忽略符号），关系越强。-0.92 极接近 -1，因此显示强负相关。-0.11 为弱负相关，+0.85 为强正相关，0.00 表示无相关。答案为A。

10. Question 9 – Ethical Issues in Psychology | 第9题 – 心理学伦理问题

Question: State one ethical issue researchers must consider when conducting a psychological study and briefly explain how it can be addressed. (2 marks) Explanation: A key ethical issue is informed consent—participants have the right to know the nature of the study and agree to take part without pressure. Researchers can address this by providing a consent form in clear language before the study begins. Other important issues include confidentiality (using codes instead of names), protection from harm (avoiding physical or psychological distress), and the right to withdraw at any time. If deception is necessary, participants must be debriefed afterwards.

题目：陈述心理学家在实施研究时必须考虑的一个伦理问题，并
