1. Overview of the Mock Paper | 模拟卷概览
The mock examination is a 50-minute paper combining four core areas of the AS specification: Social Psychology, Cognitive Psychology, Biological Psychology, and Learning Theories, integrated with Research Methods. It carries 50 marks, with questions ranging from short-answer descriptions to 12-mark evaluation tasks. The paper is designed to mirror the real exam structure, mixing knowledge recall with applied analysis and critical commentary.
本模拟卷时长为 50 分钟，融合了 AS 阶段四大核心主题——社会心理学、认知心理学、生物心理学和学习理论，并贯穿研究方法。卷面总分 50 分，题型从短答题到 12 分评析题均有覆盖。试卷结构模拟真实考试，兼顾知识复述、应用分析与批判性评论。
2. Social Psychology: Evaluating Milgram's Obedience Study | 社会心理学：米尔格拉姆服从实验评析
One 12-mark question asked candidates to describe and evaluate Milgram's (1963) study of obedience. A top-band answer must outline the aim (to test whether people would obey an authority figure instructing them to harm another person), the procedure (40 male participants, 'teacher' role, 15-volt shock increments up to 450V, experimenter's prods), and the key finding that 65% of participants administered the maximum shock. The description should also mention the visible signs of distress and the post-experimental debrief.
一道 12 分题目要求学生描述并评析米尔格拉姆（1963）的服从实验。高分答案需明确实验目的（测试普通人是否服从权威指示去伤害他人）、程序（40 名男性参与者担任“老师”，每次错误施加 15 伏特递增电击至最高 450 伏，实验者以标准化催促引导）以及关键发现在场 65% 参与者施加了最高电击。描述中还应提及参与者表现出的极度痛苦和实验后的解释说明。
Evaluation points should be balanced: the study's strength lies in high internal validity due to rigorous control in the laboratory setting, and it opened up an ethical debate that led to improved guidelines. However, it had low ecological validity (the artificial lab may not reflect real-life obedience), suffered from demand characteristics, and raised serious ethical concerns regarding deception, lack of right to withdraw, and psychological harm. A sophisticated answer might link these issues to the 'agentic state' explanation and contrast with variations like the 'touch proximity' condition.
评析部分需兼顾正反两面：该研究的优势在于实验室环境带来的高内部效度，并引发了伦理大讨论，推动了伦理准则的完善。但其生态效度低（人造实验室无法完全反映真实服从情境），可能存在需求特征，且存在欺骗、缺少退出权以及心理伤害等严重伦理问题。更深入的答案会将这些议题联系到“代理人状态”解释，并对比“肢体接触”等变体的实验结果。
3. Cognitive Psychology: The Multi-Store Model of Memory | 认知心理学：记忆多存储模型
: sensory register (large capacity, very brief duration, modality-specific coding), short-term memory (STM: capacity 7±2 chunks, duration approximately 18– ibe how information moves through the model via attention (sensory→STM) and maintenance rehearsal (STM→LTM).
试卷含有一道关于多存储模型（阿特金森与谢弗林，1968）的应用题。优秀答案需描述三个独立存储库：感觉登记（容量极大，保持时间极短，编码方式依赖感觉通道）、短时记忆（STM：容量为 7±2 组块，持续约 18–30 秒，声学编码为主）和长时记忆（LTM：容量与持续时间近乎无限，语义编码）。考生必须说明信息如何经注意（感觉登记→STM）和维持性复述（STM→LTM）在模型中流动。
Evaluation could use evidence from case studies of amnesia, such as HM (Milner, 1966), who could form new procedural memories but not new episodic memories, supporting the distinction between STM and LTM. However, the model is oversimplified — it assumes STM and LTM are unitary, whereas the working memory model (Baddeley & Hitch, 1974) demonstrates STM is an active processor with multiple components. Moreover, the emphasis on rehearsal is challenged by the fact that we often remember things without intentional rehearsal, and by the levels of processing framework.
评析可利用健忘症案例研究支撑，如 HM（米尔纳，1966）能形成新的程序性记忆却无法形成新的情景记忆，这支持了 STM 与 LTM 的分离。但该模型过于简化，假定 STM 与 LTM 各自单一均质；而工作记忆模型（巴德利与希奇，1974）表明短时记忆是一个包含多成分的主动加工系统。此外，复述的核心地位受到质疑，因为我们常常无需刻意复述就能记住信息，且加工水平说也提出了替代观点。
4. Biological Psychology: Amygdala and Aggression | 生物心理学：杏仁核与攻击行为
An 8-mark question focused on the role of the amygdala in aggression, followed by a 4-mark methodology evaluation. Research such as Raine et al. (1997) used PET scans to compare the brains of 41 murderers pleading not guilty by reason of insanity with 41 matched controls. The results showed reduced glucose metabolism in the prefrontal cortex and abnormal activity in subcortical areas including the amygdala in the murderer group, suggesting a neural basis for impulsive aggression. Other studies using electrical stimulation of the amygdala in animals have triggered aggressive responses.
一道 8 分题集中考察杏仁核在攻击行为中的作用，随后要求用 4 分评价研究方法。Raine 等人（1997）的研究使用了 PET 扫描，比较 41 名以精神错乱为由抗辩的谋杀犯与 41 名匹配对照组的大脑。结果显示，谋杀组前额叶皮层葡萄糖代谢降低，杏仁核等皮层下区域活动异常，提示了冲动攻击的神经基础。另有动物研究通过电刺激杏仁核成功诱发了攻击反应。
The 4-mark evaluation asked students to assess one research method used in such studies. PET scans offer objective, quantitative data and allow examination of deep brain structures, but they are correlational—they cannot establish cause and effect. We cannot be certain whether the amygdala abnormality caused the aggression or whether a life of aggression altered the brain. Additionally, case studies often have small, non-generalisable samples, and brain scanning itself suffers from low temporal resolution, though PET provides reasonable spatial resolution.
4 分评析题要求学生评价此类研究采用的一种研究方法。PET 扫描可提供客观、定量的数据，并能观察深层脑结构，但所得为相关关系，无法确立因果。我们无法确定是杏仁核异常导致了攻击行为，还是长期攻击生活改变了大脑。此外，案例研究样本通常较小、概化性有限，而脑部扫描技术虽然空间分辨率尚可，时间分辨率却偏低。
5. Learning Theories: Comparing Classical and Operant Conditioning | 学习理论：经典条件反射与操作性条件反射对比
A 12-mark question required comparison of classical and operant conditioning in explaining phobias. Classical conditioning (Pavlov, 1927) explains acquisition: a neutral stimulus (NS) is paired with an unconditioned stimulus (UCS) that naturally produces fear (UCR). After repeated pairing, the NS becomes a conditioned stimulus (CS) eliciting a conditioned fear response (CR), as seen in Watson and Rayner's (1920) Little Albert study. Operant conditioning (Skinner, 1938) explains maintenance: avoidance of the feared stimulus is negatively reinforcing — the reduction of anxiety strengthens the avoidance behaviour, so the phobia persists.
一道 12 分题目要求对比经典条件反射与操作性条件反射在解释恐惧症中的作用。经典条件反射（巴甫洛夫，1927）解释习得过程：中性刺激（NS）与天然引发恐惧（UCR）的非条件刺激（UCS）反复配对后，NS 转变为条件刺激（CS），引发条件性恐惧反应（CR），正如华生与雷纳（1920）的小艾伯特实验所示。操作性条件反射（斯金纳，1938）则解释维持过程：回避恐惧刺激产生负强化——焦虑的减轻强化了回避行为，恐惧症因而持续。
The table below contrasts key aspects:
下表对照了两个理论的关键层面：
| Aspect | Classical Conditioning | Operant Conditioning |
|---|---|---|
| Mechanism | Association between stimuli | Consequences of behaviour |
| Role in phobia | Acquisition through pairing | Maintenance through negative reinforcement |
| Key study | Little Albert (Watson & Rayner, 1920) | Skinner box experiments, avoidance learning |
The two explanations are complementary and can be integrated into the two-process model (Mowrer, 1947). However, both have limitations: they ignore cognitive factors (irrational beliefs, risk appraisal) and evolutionary preparedness. Not everyone who experiences a traumatic pairing develops a phobia, suggesting diathesis-stress or biological vulnerability.
两种解释相互补充，可以整合为双过程模型（莫勒，1947）。但两者均有局限：忽略了认知因素（如非理性信念、风险评估）以及进化准备性。并非每个经历创伤性配对的人都会发展出恐惧症，这暗示了素质–压力模型或生物脆弱性的作用。
6. Research Methods: Variables, Design, and Ethics | 研究方法：变量、实验设计与伦理
A scenario-based question described a psychologist investigating the effect of background noise on recall of a word list. Candidates needed to identify the independent variable (presence vs. absence of background noise) and the dependent variable (number of words correctly recalled). They then had to suggest an appropriate experimental design—independent groups design would reduce order effects and demand characteristics, but requires participant variables to be controlled; repeated measures design needs fewer participants and controls individual differences, but can suffer from practice and boredom effects.
一道情境题描述了某心理学家研究背景噪音对单词列表记忆的影响。考生需指出自变量（有无背景噪音）和因变量（正确回忆的单词数量）。随后要求提出合适的实验设计：独立组设计可减少顺序效应和需求特征，但需控制被试变量；重复测量设计所需被试较少并控制个体差异，但可能受到练习效应和疲劳效应的影响。
For ethical issues, students might discuss the need to obtain informed consent without revealing the true hypothesis to avoid demand characteristics, making mild deception likely. This must be followed by a thorough debrief. Moreover, the right to withdraw should be clearly communicated, and confidentiality must be ensured. Examiner notes appreciated reference to BPS ethical guidelines.
关于伦理问题，考生可讨论在不透露真实假设的前提下获取知情同意的必要性，以避免需求特征，因此轻微欺骗在所难免，实验后须进行充分的解释说明。此外，必须明确告知退出权并确保数据保密。考官评分时对引用英国心理学会伦理准则的答案更为赞赏。
7. Data Analysis and Interpretation | 数据分析与解读
A short task presented descriptive statistics from the noise experiment: mean words recalled in silence was 14.2 and in noise 9.8, with standard deviations of 2.1 and 3.5 respectively. Candidates were asked to interpret these figures. The difference in means suggests that background noise appeared to reduce recall performance. The larger standard deviation in the noise condition indicates greater variability in recall scores, perhaps due to individual differences in distraction susceptibility.
一个小题给出了噪音实验的描述统计：安静条件下单词回忆平均数为 14.2，噪音条件下为 9.8，标准差分别为 2.1 和 3.5。要求考生解读数据。平均数差异表明背景噪音似乎降低了回忆成绩。噪音条件下标准差更大，说明回忆分数变异性较高，可能源于个体对干扰的易感性差异。
Students were also prompted to apply an appropriate measure of central tendency and dispersion. The mean was appropriate because no extreme outliers were reported, and the standard deviation gives information about the spread around the mean. A crude comparison could be visualised with a bar chart; candidates must know how to label axes correctly: x-axis 'Noise Condition', y-axis 'Mean Number of Words Recalled'.
题目还要求考生选用恰当的中心趋势和离差量数。平均数适用，因为未报告极端异常值；标准差则提供了数据围绕平均数的分散信息。粗略比较可用条形图呈现，考生须正确标注坐标轴：x 轴为“噪音条件”，y 轴为“平均回忆单词数”。
8. Application Questions: Real-Life Scenarios | 应用题：现实场景
One question asked students to use their knowledge of social influence to explain why people might conform to a group norm even when they know it is incorrect. A top response linked this to informational social influence (ISI) — we conform because we want to be right, looking to the group for guidance in ambiguous situations, as shown in Asch's (1951) line judgement task where conformity fell when a dissenter was present. Normative social influence (NSI) explains conformity to gain approval or avoid rejection, which was evident in the public nature of Asch's procedure.
一道题要求学生运用社会影响知识解释为何人们明知群体规范错误却仍会从众。高分答案将这与信息性社会影响（ISI）联系起来——我们希望正确，在模糊情境中依赖群体指引；阿希（1951）线段判断实验中，一旦出现异议者从众率即下降。规范性社会影响（NSI）则解释为了获得认同或避免拒绝而迎合群体，这从阿希实验的公开作答特性中可见一斑。
Scenarios involving obedience could be explained through legitimacy of authority: in Milgram's study, the experimenter represented a scientific authority at a prestigious institution. The gradual commitment feature and the lack of model defiance also increased obedience. Application to real-life events, such as the Holocaust, must be handled with care, acknowledging the multidimensional nature of destructive obedience beyond a single psychological mechanism.
涉及服从的场景可通过合法性权威解释：在米尔格拉姆研究中，实验者代表了著名学府的科学权威。逐步卷入与缺少反抗榜样也促进了服从。联系现实事件如大屠杀时，须谨慎处理，承认破坏性服从的复杂性远超单一心理机制。
9. Evaluation Skills: Strengths and Weaknesses Framework | 评价技巧：优势与局限框架
Systematic evaluation is vital for high marks. Depending on the question, you can employ the GRAVE framework: Generalisability (sample size and representation), Reliability (standardised procedures, replication), Application (real-world use, therapies), Validity (internal, ecological, population), and Ethics. For example, evaluating classical conditioning explanations of phobia acquisition using this framework ensures a balanced answer that goes beyond a simple list of points.
系统的评析是获取高分的核心。根据题目，可运用 GRAVE 框架：概化性（样本量与代表性）、信度（标准化程序、可重复性）、应用（现实生活应用、疗法）、效度（内部效度、生态效度、群体效度）和伦理。以此框架评析恐惧症习得的经典条件反射解释，能使答案均衡全面，而非简单罗列要点。
Another powerful approach is the 'Point-Evidence-Explain' chain for evaluation. State a point (e.g., 'The study lacks ecological validity'), provide specific evidence from the procedure (e.g., 'Participants were asked to judge lines in an artificial lab setting'), and explain why this matters (e.g., 'This makes it difficult to generalise the findings to real-life conformity situations'). Examiners consistently reward clear explanation over mere identification of strengths or weaknesses.
另一种有力方式是“观点–证据–解释”链条。陈述观点（如“该研究缺乏生态效度”），提供程序中的具体证据（如“参与者在人工实验室中判断线段”），并解释其重要性（如“这使得研究结果难以推广到现实从众情境”）。考官始终更青睐清晰的解释，而非仅仅识别优缺点。
10. Common Mistakes and Examiner Tips | 常见错误与考官提示
Frequent errors include: describing but not evaluating when asked to 'discuss'; confusing classical and operant conditioning terminology; writing generic evaluations without tying them to the study (e.g., 'It is unethical' without stating which ethical guideline was breached); and failing to structure long-answer questions, resulting in compressed paragraphs that blur description and evaluation. Another pitfall is neglecting the command term—questions that ask 'compare' require a point-by-point comparison, not separate accounts.
常见错误有：要求“讨论”时仅描述未评价；混淆经典条件反射与操作性条件反射术语；评价空泛而未紧扣研究（如只写“这不合伦理”而未指出违反哪条伦理准则）；长答题缺乏结构，将描述与评价混杂于冗长的段落中。另一大陷阱是忽视指令术语——要求“比较”的题目需要逐点对照，而非分别叙述。
Examiner recommendations: allocate time proportionally to mark weight; use separate paragraphs for description and evaluation in 12-mark answers; always link back to the question; and when evaluating, aim to cover at least two different areas of the GRAVE framework to show depth. Practise with this mock paper, self-assess against mark schemes, and clarify concepts like independent variable and standard deviation early, because research methods appear in every unit.
考官建议：根据分值分配时间；12 分答案中将描述与评价分别成段；始终呼应题干；评价时至少涵盖 GRAVE 框架中的两个不同维度以示深度。利用这份模拟卷练习，参照评分标准自我评估，并尽早厘清自变量、标准差等概念，因为研究方法贯穿所有单元。
