1. Memory: The Multi-Store Model | 记忆：多存储模型
on for a fraction of a second with an unlimited capacity, a short-term memory (STM) that can hold 7±2 chunks of information for about 18-30 seconds, and a long-term memory (LTM) with unlimited capacity and duration. Information flows from the sensory register to STM through attention, and then into LTM via maintenance rehearsal.
记忆的多存储模型（Atkinson & Shiffrin, 1968）描述了三个分离的存储系统：感觉登记以无限的容量将原始感觉信息保持几分之一秒，短时记忆（STM）可以储存7±2个组块的信息约18-30秒，长时记忆（LTM）则拥有无限的容量和持久性。信息通过注意从感觉登记进入短时记忆，再经由维持性复述转入长时记忆。
A classic exam mistake is treating the capacities of sensory and short-term memory as interchangeable. Students frequently state that STM holds 'everything we sense' rather than a limited number of chunks. Another common error is claiming that all memories must pass through STM to reach LTM, overlooking the idea that some highly emotional or significant events (like flashbulb memories) might bypass the rehearsal loop. Always check whether a question asks about the model's structure or the processes of attention and rehearsal that control the flow.
考试中一个经典错误是将感觉记忆和短时记忆的容量混为一谈。学生常声称短时记忆能容纳‘我们感知到的一切’，而不是有限的几个组块。另一个常见错误是断言所有记忆都必须经过短时记忆才能进入长时记忆，却忽略了一些高度情绪化或意义重大的事件（如闪光灯记忆）可能绕开复述环路的可能性。答题时务必看清问题是问模型的结构还是调控信息流的注意与复述过程。
| Store / 存储 | Capacity / 容量 | Duration / 保持时间 | Key Process / 关键过程 |
|---|---|---|---|
| Sensory Register (感觉登记) | Unlimited (无限) | ¼-½ second (¼-½ 秒) | Attention (注意) |
| STM (短时记忆) | 7±2 chunks (7±2 个组块) | 18-30 seconds (18-30 秒) | Maintenance rehearsal (维持性复述) |
| LTM (长时记忆) | Unlimited (无限) | Potentially permanent (可达永久) | Encoding & retrieval (编码与提取) |
2. Working Memory Model & Its Misconceptions | 工作记忆模型及其常见误解
Baddeley and Hitch's (1974) working memory model replaced the idea of a unitary STM with a multi-component system. It consists of the central executive, which directs attention and coordinates the two slave systems: the phonological loop (processing verbal and auditory information) and the visuospatial sketchpad (handling visual and spatial data). A later addition, the episodic buffer, integrates information from different sources into a coherent sequence over time.
Baddeley 和 Hitch（1974）提出的工作记忆模型用一个多成分系统取代了单一短时记忆的构想。它由中央执行器（主导注意并协调两个子系统）、语音回路（处理言语和听觉信息）和视空间画板（处理视觉和空间数据）构成。后来加入的情境缓冲器能将不同来源的信息整合成时间上有序的连贯片段。
The most frequent misunderstanding is treating the central executive as a store of information, when in fact it is a purely attentional controller that does not hold data. Many answers wrongly describe the phonological loop as dealing with 'all sound', forgetting it specifically handles speech-based material, while the visuospatial sketchpad deals with what things look like and where they are. Also, students often overestimate the capacity of the slave systems – each has a limited capacity, not an unlimited one. Examiners look for precise phrases like 'limited-capacity temporary storage systems' rather than 'unlimited memory buffers'.
最常见的误解是将中央执行器当作信息储存库，而它实际上只是负责分配注意却不保存数据的控制器。很多答案错误地描述语音回路处理‘所有声音’，却忘记它专门针对言语材料，而视空间画板处理物体外观和空间位置。此外，学生经常高估子系统的容量——每个子系统容量有限，而非无限。考官希望看到‘容量有限的临时存储系统’这样准确的表述，而不是‘无限的记忆缓冲器’。
3. Interference Theory of Forgetting | 遗忘的干扰理论
Interference theory proposes that forgetting occurs because one memory disrupts the recall of another. There are two main types: proactive interference, where older information interferes with the recall of newer information, and retroactive interference, where newer learning harms the recall of older memories. A typical classroom demonstration is learning two lists of words – performance on the second list can be reduced by the first (proactive), or recall of the first can be impaired after learning the second (retroactive).
干扰理论提出，遗忘发生是因为一段记忆干扰了另一段记忆的提取。主要有两种类型：前摄干扰，即旧信息干扰新信息的记忆；倒摄干扰，即新学习的内容损害了旧记忆的提取。课堂上常通过记忆两个词表来演示：第一张表会影响第二张表的表现（前摄），而学完第二张表后对第一张表的回忆也会受损（倒摄）。
A very common exam blunder is confusing interference with decay theory. Decay suggests memories fade simply due to the passage of time; interference specifically requires competing information. In a scenario where a student mixes up their old and new phone numbers, it's proactive interference if the old number intrudes when recalling the new one. If asked to identify the type of interference, always ask yourself: which material is being recalled, and which material is causing the difficulty? Labelling them accurately separates top-grade answers from the rest.
极常见的考试错误是把干扰理论和衰退理论混淆。衰退理论认为记忆仅仅因为时间流逝而淡化；干扰理论则明确需要竞争信息。如果一名学生弄混了旧号码和新号码，在回忆新号码时旧号码跑出来——这就是前摄干扰。如果题目要求辨别干扰类型，务必自问：正在回忆的是哪段材料？是什么材料造成了困难？准确给它们贴上标签，这是高分答案与普通答案的分水岭。
4. Social Influence: Conformity & Asch's Study | 社会影响：从众与阿希实验
Solomon Asch's (1951) line judgement experiment is the classic investigation into conformity. In a group setting where confederates deliberately gave wrong answers about the length of lines, about 37% of the responses across all critical trials were conformist, and a striking 75% of participants conformed at least once. Key factors affecting conformity include the size of the majority (up to about three confederates), the unanimity of the group, and the difficulty of the task.
Solomon Asch（1951）的线段判断实验是从众研究的经典之作。在小组情境下，当假被试故意给出关于线段长度的错误答案时，所有关键试次中约有37%的回答是从众的，而高达75%的参与者至少从众过一次。影响从众的关键因素包括：多数派的规模（最多约三人）、群体的一致性和任务难度。
Many students mistakenly remember the conformity rate as much higher than 37%, perhaps because the fact that 'most people conformed at least once' overshadows the trial-by-trial statistic. A more subtle error is confusing Asch's conformity demonstration with obedience studies. Conformity involves going along with a group's pressure without a direct order, whereas obedience involves responding to a direct instruction from an authority figure. When an exam question describes a group influence, be careful not to bring in Milgram's terminology unless there is an explicit command.
许多学生错误地记成从众率远高于37%，或许是因为‘大部分人至少从众过一次’的事实掩盖了按试次统计的数据。一个更微妙的错误是把阿希的从众演示与服从研究混为一谈。从众是在没有直接命令的情况下，跟随群体的压力；而服从则是对权威人物直接指令的回应。当考题描述的是群体影响时，不要搬出米尔格拉姆的术语，除非题中明确出现了命令。
5. Obedience: Milgram's Research & Ethical Issues | 服从：米尔格拉姆研究与伦理问题
Stanley Milgram's (1963) obedience experiment shocked the world when 65% of participants administered what they believed were lethal 450-volt shocks to a learner, simply because an experimenter in a lab coat instructed them to continue. The procedure manipulated proximity, authority setting, and group pressure to demonstrate that situational factors, rather than disposition, can generate extreme obedience. The study remains a landmark in social psychology, but it also ignited fierce debate about research ethics.
Stanley Milgram（1963）的服从实验震惊世界：65%的参与者仅仅因为穿着白大褂的实验者命令他们继续，便对学习者施加了他们以为是致命的450伏电击。实验通过操纵接近程度、权威环境及群体压力，证明了情境因素而非个人特质可以引发极端的服从行为。该研究至今仍是社会心理学的里程碑，但也引发了关于研究伦理的激烈争论。
A typical error in answers is writing that '100% of participants obeyed', when in fact 35% defied the experimenter at some point. Also, students often describe the study using the term 'conformity' rather than 'obedience'; remember that participants were complying with a direct order, not the unspoken norm of a group. On the ethics side, many responses list 'deception', 'lack of informed consent' and 'psychological harm' without connecting them to specific British Psychological Society (BPS) guidelines. To score full marks you need to say that deception violated the principle of informed consent, participants were not clearly told they could withdraw, and the distress observed conflicts with the guideline of protection from harm.
答案中的典型错误是写‘100%的参与者都服从了’，而实际上有35%的参与者在某个时刻违抗了实验者。同时，学生经常用‘从众’而非‘服从’来描述该研究；要记住，参与者服从的是直接命令，而不是群体的隐性规范。在伦理方面，许多回答列出‘欺骗’、‘缺乏知情同意’和‘心理伤害’，却没有将它们与具体的英国心理学会（BPS）指南联系起来。要拿到满分，必须指出欺骗违背了知情同意的原则，参与者没有被明确告知可以退出，而观察到的痛苦表现违背了免受伤害的指南。
6. Research Methods: IV, DV, and Controls | 研究方法：自变量、因变量与控制变量
In any experiment, the independent variable (IV) is the factor that is manipulated or changed by the researcher, or the naturally occurring difference in a natural experiment (e.g., gender or age). The dependent variable (DV) is what is measured – the outcome that may be affected by the IV. Controlled variables (CVs) are all the other potential influences that must be kept constant to prevent them from becoming confounding variables that distort the results.
在任何实验中，自变量（IV）是研究者操纵或改变的因素，或在自然实验中天然存在的差异（如性别或年龄）。因变量（DV）是被测量的内容——即可能受自变量影响的结果。控制变量（CV）是所有其他必须保持恒定的潜在影响因素，以防它们变成混淆变量，歪曲实验结果。
The number one mistake is mixing up the IV and the DV, particularly when the IV is not being directly manipulated but is a characteristic of the participants. When you read a scenario, ask: 'What is being changed or compared?' (that's the IV) and 'What result is being recorded?' (that's the DV). Another frequent slip is claiming that all extraneous variables can be controlled, which is rarely true in a classroom-based experiment. A good answer distinguishes between standardised control variables and those that might unexpectedly become confounding variables. Practice spotting the IV and DV in stated research questions – the phrasing 'the effect of X on Y' makes X the IV and Y the DV.
头号错误是混淆自变量和因变量，尤其是当自变量不是直接操纵而是参与者固有特征时。读到情境时，要问：‘什么被改变了或正在被比较？’（那是自变量）‘什么结果被记录下来了？’（那是因变量）。另一个常见疏漏是声称所有额外变量都能被控制，这在课堂实验中几乎不可能。高质量的答案会区分标准化的控制变量和那些可能意外成为混淆变量的因素。多练习从给定的研究问题中识别自变量和因变量——‘X对Y的影响’这一表述中，X就是自变量，Y是因变量。
7. Experimental Designs & Counterbalancing | 实验设计与平衡法
The three most common experimental designs are independent groups (different participants in each condition), repeated measures (the same participants take part in all conditions), and matched pairs (participants are matched on a key variable and then split across conditions). Each design has distinct strengths: for example, repeated measures eliminates participant variables, but it introduces order effects (practice, fatigue, boredom) that can bias the results.
最常见的三种实验设计是独立组（不同条件下使用不同参与者）、重复测量（同一批参与者经历所有条件）和匹配对（根据某个关键变量将参与者配对，再分到不同条件）。每种设计都有独特的优势：例如，重复测量可以消除参与者变量，但却引入顺序效应（练习、疲劳、厌倦），可能使结果产生偏差。
A frequent misconception is that counterbalancing completely removes order effects. In reality, counterbalancing (e.g., ABBA design) only distributes order effects evenly across conditions, making them a constant rather than a bias; it does not abolish them. Another common error is believing that a matched pairs design eradicates participant variables entirely. While matching on traits like IQ or memory score reduces individual differences, it never matches participants perfectly on everything. When evaluating designs, be precise: say 'reduces participant variables' rather than 'eliminates them'.
一个常见误解是平衡法可以完全消除顺序效应。实际上，平衡法（如ABBA设计）只是将顺序效应均衡分配到各个条件中，使其成为一个常数而非偏误，并不能消除它们。另一个常见错误是认为匹配对设计能彻底消除参与者变量。虽然根据智商或记忆分数等特质进行匹配能减少个体差异，但绝不可能在所有方面完美匹配。在评价设计时一定要精确：说‘减少参与者变量’而不是‘消除它们’。
8. Interpreting Data: Graphs and Descriptive Statistics | 数据解释：图表与描述统计
OCR Psychology assesses your ability to interpret bar charts (used for discrete or categorical data), histograms (continuous data with equal intervals), and scattergrams (representing correlations). Descriptive statistics such as mean, median, mode, and range summarise data, but they must be selected carefully. For example, the mean is sensitive to extreme scores; in a skewed distribution, the median is a better measure of central tendency.
OCR心理学会考察你解读柱状图（用于离散或分类数据）、直方图（等距的连续数据）和散点图（展示相关性）的能力。均值、中位数、众数和全距等描述统计能概括数据，但选择时需谨慎。比如均值对极端分数敏感；在偏态分布中，中位数是更好的集中趋势量数。
The most damaging error is interpreting a correlation shown in a scattergram as causation. Just because two variables are related (e.g., hours of gaming and aggression scores) does not mean one causes the other; a third variable could be responsible. Also, students often choose the mode for interval data or apply the mean without checking for outliers, which would be criticised by examiners. When describing a graph, always mention the direction of any trend and whether the data are continuous or discrete – this shows statistical awareness that earns marks.
最具破坏性的错误是把散点图中的相关性解读为因果关系。两个变量有关联（如玩游戏的小时数和攻击性得分），绝不意味着一个导致了另一个；可能存在第三个变量。同时，学生常对等距数据使用众数，或忽略异常值直接套用均值，这都会受到考官批评。在描述图表时，务必指出趋势的方向以及数据是连续还是离散的——这体现了统计意识，能够得分。
9. Psychological Problems: Depression – Biological vs Cognitive Explanations | 心理问题：抑郁症的生物学与认知解释
The biological explanation of depression often centres on the serotonin hypothesis: low levels of the neurotransmitter serotonin are linked to depressive symptoms because serotonin helps regulate mood, sleep and appetite. Genetic predisposition also plays a role, evidenced by twin studies showing higher concordance rates in monozygotic twins. The cognitive explanation emphasises maladaptive thought patterns, such as Beck's negative triad (negative views of the self, the world and the future) and Ellis's ABC model (activating event, belief, consequence).
抑郁症的生物学解释常围绕血清素假说：神经递质血清素水平偏低与抑郁症状相关，因为血清素有助于调节情绪、睡眠和食欲。遗传易感性也发挥作用，双生子研究显示同卵双生子有更高的共病率。认知解释则强调适应不良的思维模式，如Beck的负面三角（对自我、世界和未来的负面看法）和Ellis的ABC模型（激发事件、信念、后果）。
Many students fall into the reductionist trap by claiming that 'low serotonin causes depression' as if it were the sole cause. In exam answers, it is crucial to state that we observe a correlation between serotonin and depression – we cannot be certain about causation, and other factors (cognitive, social, life events) interact. Also, a candidate might confuse Beck's negative triad with Ellis's ABC model, attributing 'activating events' to Beck. Practise making clear distinctions: Beck focuses on automatic negative thoughts about the self, world and future; Ellis focuses on how irrational beliefs triggered by an event lead to emotional consequences.
很多学生陷入还原论陷阱，声称‘低血清素导致抑郁症’，好像这是唯一原因。在考试答案中，关键是要说明我们观察到的是血清素与抑郁症之间的相关关系——我们无法确定因果关系，且其他因素（认知、社会、生活事件）也相互作用。此外，考生还可能混淆Beck的负面三角与Ellis的ABC模型，把‘激发事件’归给Beck。要练习做出明确区分：Beck聚焦于关于自我、世界和未来的自动负面思维；Ellis则聚焦于由事件引发的不理性信念如何导致情绪后果。
10. Attachment: Ainsworth's Strange Situation | 依恋：安斯沃思的陌生情境
Mary Ainsworth's Strange Situation (1978) is a controlled observation procedure designed to assess the quality of attachment between an infant and their caregiver. It consists of eight episodes involving separation, reunion, and the presence of a stranger. Based on the infant's behaviour, especially during reunion, attachment is classified as secure (Type B, about 66%), insecure-avoidant (Type A, about 22%) or insecure-resistant (Type C, about 12%).
Mary Ainsworth的陌生情境（1978）是一种控制观察程序，旨在评估婴儿与照料者之间的依恋质量。它包括八个片段，涉及分离、重聚和陌生人的在场。根据婴儿的行为，特别是在重聚时的表现，依恋被分为安全型（B型，约占66%）、不安全-回避型（A型，约占22%）或不安全-反抗型（C型，约占12%）。
