欢迎阅读IB心理学终极复习指南。本概要将核心考纲浓缩为易于掌握的知识点，涵盖生物、认知和社会文化三种分析水平、研究方法、伦理以及评估策略。无论你学习标准级别（SL）还是高级级别（HL），理解这一框架对于在试卷一、试卷二和内部评估中取得成功至关重要。
1. Course Structure and Levels | 课程结构与分级
IB Psychology is offered at Standard Level (SL) and Higher Level (HL). SL students study the core (all three levels of analysis), one optional topic, and complete an experimental study for internal assessment. HL students study the same core but in greater depth, choose two options, and explore additional research methods including qualitative analysis.
IB心理学分为标准级别（SL）和高级级别（HL）。SL学生需学习核心内容（全部三种分析水平）、一个选修主题，并完成一个实验研究作为内部评估。HL学生学习相同的核心，但深度更大，需选择两个选修主题，并探索包括定性分析在内的额外研究方法。
The course is designed around 150 hours of teaching for SL and 240 hours for HL, with the additional time used for deepening understanding, conducting qualitative research, and studying a second option.
该课程SL教学设计约150小时，HL约240小时，额外时间用于深化理解、进行定性研究以及学习第二个选修主题。
2. Assessment Components at a Glance | 评估组成一览
IB Psychology assessment consists of two external exam papers and an internal assessment. Paper 1 tests the core levels of analysis with short-answer and essay questions. Paper 2 assesses the optional topics. The internal assessment requires students to design, conduct, and write up a simple experimental study.
IB心理学评估由两个外部考试试卷和一个内部评估组成。试卷一通过简答题和论述题考查核心分析水平。试卷二考查选修主题。内部评估要求学生设计、实施并撰写一份简单的实验研究报告。
For SL, Paper 1 lasts 2 hours and weighs 50% of the final grade; Paper 2 lasts 1 hour and weighs 25%; the IA weighs 25%. For HL, Paper 1 is 3 hours (40%), Paper 2 2 hours (20%), IA 20%, and HL students also answer an additional Paper 3 focusing on qualitative research methods (20%).
对于SL，试卷一为2小时，占最终成绩50%；试卷二为1小时，占25%；内部评估占25%。对于HL，试卷一3小时（40%），试卷二2小时（20%），内部评估20%，HL学生还需作答专注于定性研究方法的试卷三（20%）。
Options available include Abnormal Psychology, Developmental Psychology, Health Psychology, Psychology of Human Relationships, and Sport Psychology. SL students study one option; HL students study two.
可选的选修主题包括异常心理学、发展心理学、健康心理学、人际关系心理学和运动心理学。SL学生学习一个选修主题；HL学生学习两个。
3. Research Methods: The Foundation | 研究方法：基础
Research methods are woven throughout the entire IB Psychology syllabus. Students must be able to evaluate experiments, correlational studies, observations, interviews, and case studies. Understanding strengths and limitations of each method is crucial for answering questions in all papers.
研究方法贯穿整个IB心理学考纲。学生必须能够评价实验、相关研究、观察、访谈和个案研究。理解每种方法的优点和局限性对于解答所有试卷中的问题至关重要。
Key concepts include independent and dependent variables, control of confounding variables, sampling techniques, and the distinction between quantitative and qualitative data. For HL, an in-depth understanding of qualitative methods—such as content analysis and grounded theory—is expected in Paper 3.
核心概念包括自变量和因变量、混淆变量的控制、抽样技术以及定量数据与定性数据的区别。对于HL，试卷三要求学生深入理解定性方法，如内容分析和扎根理论。
Students also learn to interpret basic descriptive statistics (mean, median, mode, standard deviation) and inferential statistics like the t-test when evaluating research. However, statistical calculations are not required in the IB exam.
学生还需学习如何解读基本描述性统计（平均值、中位数、众数、标准差）和推断性统计（如t检验）以评价研究。不过，IB考试不要求统计计算。
4. Ethical Considerations in Psychological Research | 心理学研究的伦理考量
All psychological studies discussed in the IB course must be examined through the lens of ethics. Students learn about informed consent, deception, debriefing, confidentiality, and the right to withdraw. The BPS and APA ethical guidelines are referenced.
IB课程中讨论的所有心理学研究都必须从伦理角度加以审视。学生将了解知情同意、欺骗、事后解释、保密以及退出权。参考英国心理学会（BPS）和美国心理学会（APA）的伦理指南。
For the Internal Assessment, students must follow strict ethical standards, avoiding harm, ensuring anonymity, and obtaining consent from participants. Studies involving vulnerable groups or sensitive topics require extra caution and must be justified ethically.
在进行内部评估时，学生必须遵循严格的伦理标准，避免伤害、确保匿名性并获得参与者的知情同意。涉及弱势群体或敏感话题的研究需要格外谨慎，并必须从伦理角度进行论证。
Classic studies such as Milgram’s obedience experiment and Watson and Rayner’s Little Albert study are often used to discuss ethical breaches, helping students evaluate the balance between research value and participant welfare.
经典研究如米尔格拉姆的服从实验以及华生和雷纳的小阿尔伯特研究常被用来讨论伦理违规，帮助学生权衡研究价值与参与者福祉之间的平衡。
5. Biological Level: Brain and Neurotransmitters | 生物水平：大脑与神经递质
The biological level of analysis assumes that behaviour has a physiological basis. Key topics include brain localization, neuroplasticity, and the role of neurotransmitters. Studies such as HM (Milner) demonstrate how damage to the hippocampus affects memory, while the case of Phineas Gage illustrates the link between the frontal lobe and impulse control.
生物分析水平假定行为有其生理基础。核心主题包括大脑功能定位、神经可塑性以及神经递质的作用。诸如HM（Milner）的研究表明海马体损伤如何影响记忆，而菲尼亚斯·盖奇的案例则说明了额叶与冲动控制之间的关联。
Neurotransmitters such as acetylcholine and serotonin are examined through their agonists and antagonists. For instance, the effect of SSRIs on serotonin levels helps explain the biological underpinnings of mood disorders. Students evaluate both supporting and contradictory evidence.
人们通过激动剂和拮抗剂来研究乙酰胆碱和血清素等神经递质。例如，选择性血清素再摄取抑制剂（SSRIs）对血清素水平的影响有助于解释情绪障碍的生物学基础。学生需评估支持性和矛盾性的证据。
Neuroplasticity is illustrated by Maguire et al.’s (2000) study on London taxi drivers, showing that spatial navigation experience can increase grey matter volume in the hippocampus. Such research highlights the dynamic interplay between environment and biology.
神经可塑性可由Maguire等人（2000）对伦敦出租车司机的研究予以说明，该研究表明空间导航经验可增加海马体的灰质体积。此类研究突显了环境与生物学之间动态的相互作用。
6. Biological Level: Hormones, Pheromones and Genetics | 生物水平：激素、信息素与遗传学
Hormones such as cortisol and adrenaline influence behaviour, particularly in stress and emotional memory. Studies like Cahill and McGaugh (1995) show that adrenaline enhances memory consolidation of emotional events, providing a biological explanation for flashbulb memories.
皮质醇和肾上腺素等激素会影响行为，特别是在应激和情绪记忆方面。诸如Cahill和McGaugh（1995）的研究表明，肾上腺素能增强情绪事件记忆的巩固，这为闪光灯记忆提供了生物学解释。
The role of pheromones in human behaviour remains controversial. While animal studies offer strong evidence, human research—such as the McClintock effect on menstrual synchrony—faces methodological criticism. Students must evaluate both sides of the debate.
信息素在人类行为中的作用仍存争议。虽然动物研究提供了强有力的证据，但人类研究——如关于月经同步的麦克林托克效应——面临方法学上的批评。学生必须权衡辩论的双方。
Genetic influences are explored through twin and adoption studies. The Minnesota Twin Study and research on the 5-HTT gene and depression illustrate how genes can predispose individuals to certain behaviours, always interacting with environmental factors.
基因影响通过双生子和领养研究得以探索。明尼苏达双生子研究以及关于5-HTT基因与抑郁症的研究表明，基因可使个体对某些行为具有易感性，且始终与环境因素相互作用。
7. Cognitive Level: Memory Models and Processes | 认知水平：记忆模型与过程
The cognitive level of analysis focuses on mental processes like memory, thinking, and decision making. Students learn to evaluate memory models, such as the Multi-Store Model (Atkinson and Shiffrin) and the Working Memory Model (Baddeley and Hitch).
认知分析水平侧重于记忆、思维和决策等心理过程。学生需学习评价记忆模型，如多存储模型（Atkinson和Shiffrin）和工作记忆模型（Baddeley和Hitch）。
The Multi-Store Model proposes separate sensory, short-term, and long-term stores. Supporting evidence includes the serial position effect (primacy and recency). However, the model is challenged by the Working Memory Model, which introduces a central executive and slave systems, as demonstrated by dual-task experiments.
多存储模型提出感觉记忆、短时记忆和长时记忆三个独立存储系统。支持证据包括序列位置效应（首因效应和近因效应）。然而，工作记忆模型对该模型提出了挑战，引入了中央执行系统和从属系统，这通过双任务实验得到了证实。
Schema theory is another central concept, explaining how memories are reconstructed rather than perfectly recorded. Bartlett’s ‘War of the Ghosts’ study shows that cultural schemas can distort recall, leading to omissions and rationalisations.
图式理论是另一个核心概念，它解释了记忆如何被重构而非完美记录。巴特利特的“幽灵之战”研究表明，文化图式可以扭曲回忆，导致遗漏和合理化。
8. Cognitive Level: Thinking, Decision Making and Biases | 认知水平：思维、决策与偏见
Cognitive biases such as confirmation bias, anchoring effect, and the framing effect have profound impacts on decision making. Tversky and Kahneman’s prospect theory explains how people evaluate gains and losses differently, leading to irrational choices.
确认偏误、锚定效应和框架效应等认知偏见对决策有深远影响。特沃斯基和卡尼曼的前景理论解释了人们如何以不同方式评价收益和损失，从而导致非理性的选择。
The dual-process model of thinking distinguishes between intuitive System 1 (fast, automatic) and analytical System 2 (slow, effortful). This model helps explain errors in judgement and can be applied to real-world contexts such as medical diagnosis and financial decisions.
思维的双过程模型区分了直觉性的系统1（快速、自动）和分析性的系统2（缓慢、费力）。该模型有助于解释判断错误，并可应用于医学诊断和金融决策等现实情境。
Studies on cognitive dissonance (Festinger) and reconstructive memory illustrate how our beliefs shape perception and recall. This reinforces the IB emphasis on evaluating the validity of cognitive models through empirical evidence and real-life applications.
关于认知失调（费斯廷格）和重构记忆的研究说明了信念如何塑造感知和回忆。这强化了IB心理学通过实证证据和现实应用来评价认知模型有效性的重点。
9. Sociocultural Level: Social Identity and Conformity | 社会文化水平：社会认同与从众
The sociocultural level of analysis investigates how the social environment and culture influence behaviour. Tajfel’s Social Identity Theory (SIT) explains how individuals categorise themselves into in-groups and out-groups, leading to in-group favouritism and prejudice.
社会文化分析水平探究社会环境和文化如何影响行为。塔吉费尔的社会认同理论（SIT）解释了个体如何将自身归类为内群体和外群体，从而导致内群体偏爱和偏见。
Conformity studies by Asch demonstrate the power of group pressure even when the correct answer is obvious. Factors such as group size, unanimity, and self-esteem affect the level of conformity, offering insights into social influence.
阿希的从众研究展示了群体压力的力量，即便正确答案显而易见。群体规模、一致性和自尊等因素会影响从众程度，这为理解社会影响提供了洞见。
Obedience to authority, illustrated by Milgram’s experiments, is another key topic. Students evaluate the ethical and methodological concerns surrounding the study while discussing its implications for understanding real-world atrocities and whistle-blowing behaviour.
服从权威，以米尔格拉姆的实验为例，是另一个关键主题。学生在讨论该研究对理解现实世界暴行与举报行为的启示时，还需评价其伦理和方法学问题。
10. Sociocultural Level: Cultural Dimensions and Norms | 社会文化水平：文化维度与规范
Hofstede’s cultural dimensions—such as individualism vs. collectivism and power distance—provide a framework for comparing behaviours across cultures. For example, conformity rates are higher in collectivist cultures, and decisions about relationships often reflect cultural values.
霍夫斯泰德的文化维度——如个人主义与集体主义、权力距离——为跨文化行为比较提供了一个框架。例如，集体主义文化中的从众率更高，关于关系的决策往往反映文化价值观。
Enculturation and acculturation explain how individuals learn and adapt to cultural norms. Berry’s acculturation model identifies strategies like integration, assimilation, separation, and marginalisation, highlighting the psychological impacts of cultural transition.
文化濡化和涵化解释了个体如何学习并适应文化规范。贝里的涵化模型识别了整合、同化、分离和边缘化等策略，突显了文化变迁带来的心理影响。
Studies on cultural norms include research on personal space, eye contact, and the role of cultural scripts in defining aggression or helping behaviour. The IB syllabus encourages students to challenge ethnocentric assumptions and adopt a culturally sensitive perspective.
关于文化规范的研究包括对个人空间、眼神接触以及文化脚本在定义攻击性或助人行为中作用的研究。IB考纲鼓励学生挑战民族中心主义假设，并采取文化敏感的视角。
11. Internal Assessment: The Experimental Study | 内部评估：实验研究
The Internal Assessment gives students the opportunity to conduct a simple, ethically sound experiment related to a psychological theory or study. It must follow the structure of an introduction, design, procedure, results, discussion, and references.
内部评估为学生提供了一个机会，让他们能够开展一项与心理学理论或研究相关的、符合伦理的简单实验。它必须遵循绪论、设计、程序、结果、讨论和参考文献的结构。
Students are required to select an independent variable, measure a dependent variable, and control extraneous variables. The report includes descriptive statistics (graph or table) and a verbal interpretation of the findings, never statistical testing.
学生必须选择一个自变量，测量一个因变量，并控制额外变量。报告包含描述性统计（图表或表格）以及对结果的口头解读，不要求进行统计检验。
Ethical compliance is paramount. The study must guarantee informed consent, confidentiality, and the right to withdraw. Common IA topics include replicating the Stroop effect, testing memory using word lists, and investigating anchoring bias.
伦理合规至关重要。研究必须保证知情同意、保密和退出权。常见的内部评估主题包括复制斯特鲁普效应、使用词表测试记忆以及调查锚定偏见。
12. Exam Tips and Command Terms | 考试技巧与指令术语
Command terms guide the depth of answers. Terms like ‘describe’ and ‘outline’ require straightforward factual recall, while ‘explain’, ‘evaluate’, and ‘to what extent’ demand critical analysis and use of research evidence.
指令术语指引着答案的深度。像“describe”和“outline”这样的术语要求直接的事实回忆，而“explain”、“evaluate”和“to what extent”则要求批判性分析并运用研究证据。
For Paper 1 essays (SAQs and ERQs), always use studies to support your arguments. A well-structured ERQ introduces the topic, defines key concepts, presents two or three studies with evaluation, and concludes by answering the question directly.
对于试卷一的短文题和论述题，始终要用研究来支持你的论点。一篇结构良好的论述题应引入主题、定义关键概念、呈现两到三个研究并进行评价，最后直接回答问题得出结论。
Time management is critical. Allocate roughly one minute per mark. For HL Paper 3, practice answering qualitative research questions by applying knowledge of methods, ethics, and data analysis to unfamiliar stimulus material.
时间管理至关重要。大致每一分对应一分钟作答时间。对于HL试卷三，要练习通过将方法、伦理和数据分析的知识应用于不熟悉的刺激材料来回答定性研究问题。
