1. Research Methods in Psychology | 心理学研究方法
Psychology is a science, and research methods are the systematic procedures used to collect and analyse data. The two main types of research are experiments and non-experimental methods such as observations, questionnaires, and interviews. In an experiment, a researcher manipulates an independent variable (IV) to see its effect on a dependent variable (DV), while controlling extraneous variables to ensure a fair test.
心理学是一门科学，研究方法是收集和分析数据的系统程序。两大主要研究类型是实验和非实验方法，如观察法、问卷调查法和访谈法。在实验中，研究者操纵自变量（IV）来观察其对因变量（DV）的影响，同时控制额外变量以确保测试的公平性。
A hypothesis is a precise, testable statement predicting the relationship between the IV and the DV. There are two types: a directional (one-tailed) hypothesis states the expected direction of the effect (e.g. ‘students who drink caffeine will have higher test scores than those who do not’), while a non-directional (two-tailed) hypothesis simply predicts a difference without specifying the direction (e.g. ‘there will be a difference in test scores between caffeine and non-caffeine groups’).
假设是一种精确的、可检验的陈述，预测IV和DV之间的关系。假设有两种类型：定向（单尾）假设指出预期的效应方向（例如’喝咖啡因的学生考试成绩会高于不喝的学生’），而非定向（双尾）假设只预测有差异但不指明方向（例如’咖啡因组和非咖啡因组在考试成绩上会存在差异’）。
Operationalisation is the process of clearly defining variables in measurable terms. For example, ‘aggression’ might be operationalised as the number of times a child hits a doll in a ten-minute observation. Without operationalisation, a study cannot be reliably repeated.
操作化是指用可测量的术语清晰地定义变量的过程。例如，’攻击性’可以被操作化为孩子在十分钟观察中击打玩偶的次数。没有操作化，研究便无法可靠地重复。
2. Experimental Design | 实验设计
Independent groups design uses different participants in each condition of the experiment. The main strength is that there are no order effects, but the weakness is participant variables may differ between groups. Random allocation is used to minimise this.
独立组设计在实验的每个条件下使用不同的参与者。其主要优点是没有顺序效应，但缺点在于各组间的参与者变量可能不同。随机分配被用来尽量减少这种影响。
Repeated measures design uses the same participants in all conditions. The strength is that participant variables are controlled, but order effects can occur (e.g. practice or boredom). Counterbalancing helps to reduce order effects.
重复测量设计在所有条件下使用相同的参与者。优点在于控制了参与者变量，但可能出现顺序效应（如练习效应或厌倦）。平衡技术有助于减少顺序效应。
Matched pairs design involves pairing participants on key characteristics and then randomly assigning each pair to different conditions. This reduces participant variables without order effects, but it can be time-consuming to match participants precisely.
配对组设计先根据关键特征对参与者进行配对，然后将每对中的人随机分配到不同的条件。这既减少了参与者变量又不会产生顺序效应，但精确匹配参与者可能比较耗时。
| Design | Strengths | Weaknesses |
| Independent Groups | No order effects | Participant variables |
| Repeated Measures | Controls participant variables | Order effects |
| Matched Pairs | No order effects, reduced participant variables | Time-consuming |

3. Ethical Guidelines | 伦理准则
The British Psychological Society (BPS) sets ethical principles to protect participants. Informed consent means participants must be given full information about the study and agree to take part. However, sometimes deception is used, but it must be justified and followed by a thorough debrief.
英国心理学会（BPS）制定了保护参与者的伦理原则。知情同意意味着必须向参与者提供研究的全部信息并获得同意。然而有时会使用欺骗手段，但必须有其正当理由，并在事后进行充分的解释说明。
Participants have the right to withdraw from the study at any time, and their data must be kept confidential. Protection from harm means researchers must ensure participants do not suffer physical or psychological stress beyond what they would encounter in everyday life.
参与者有权随时退出研究，其数据必须保密。免受伤害原则要求研究者确保参与者不会遭受超出日常生活中可能遇到的身心压力。
Deception should be avoided, but if it is necessary, participants must be debriefed afterwards: the true aims of the study are explained, and any concerns are addressed. Researchers must also respect privacy and obtain consent from parents or guardians when working with children under 16.
应避免欺骗，但如果必要，之后必须对参与者进行事后说明：解释研究的真实目的，并处理任何疑虑。研究者还必须尊重隐私，对于16岁以下的儿童，需征得家长或监护人的同意。
4. Biological Psychology: The Brain and Neurons | 生物心理学：大脑与神经元
The central nervous system consists of the brain and spinal cord. The brain has several key regions: the frontal lobe is involved in decision-making and personality, the temporal lobe in hearing and memory, the parietal lobe in sensory processing, and the occipital lobe in vision.
中枢神经系统由大脑和脊髓组成。大脑有几个关键区域：额叶参与决策和人格，颞叶负责听觉和记忆，顶叶处理感觉信息，枕叶负责视觉。
Neurons are specialised cells that transmit information using electrical and chemical signals. A typical neuron has a cell body (soma), dendrites that receive signals, an axon that carries the impulse away, and terminal buttons that release neurotransmitters into the synapse.
神经元是使用电信号和化学信号传递信息的特化细胞。一个典型的神经元包含细胞体，接收信号的树突，传导冲动的轴突，以及将神经递质释放到突触中的终扣。
Synaptic transmission occurs when an electrical impulse reaches the end of an axon, triggering the release of neurotransmitters. These chemicals cross the synaptic gap and bind to receptor sites on the next neuron, creating either an excitatory or inhibitory effect.
突触传递发生在电冲动到达轴突末端时，触发神经递质的释放。这些化学物质穿过突触间隙，与下一个神经元上的受体位点结合，产生兴奋或抑制效应。
5. Cognitive Psychology: Models of Memory | 认知心理学：记忆模型
The multi-store model of memory (Atkinson and Shiffrin, 1968) proposes three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM). Information flows between them through attention and rehearsal.
记忆的多存储模型（Atkinson 和 Shiffrin, 1968）提出了三个独立的存储器：感觉登记、短时记忆（STM）和长时记忆（LTM）。信息通过注意和复述在它们之间流动。
The sensory register holds a large amount of information for a very brief duration (less than half a second for visual information). If attention is paid to it, the information moves to STM. STM has a limited capacity of 7 ± 2 items and a duration of about 18-30 seconds without rehearsal.
感觉登记保存大量信息，但持续时间极短（视觉信息不到半秒）。如果受到注意，信息就会进入短时记忆。短时记忆的容量有限，为7±2个组块，持续时间在没有复述的情况下约为18-30秒。
Maintenance rehearsal keeps information in STM, but elaborative rehearsal is needed to transfer it into LTM, which has potentially unlimited capacity and duration. Evidence for the separate stores comes from studies such as the serial position effect, where primacy and recency effects support the existence of LTM and STM respectively.
维持性复述使信息保持在短时记忆中，但需要精细复述才能将其转入长时记忆，后者容量和持续时间几乎没有限制。支持独立存储的证据来自系列位置效应等研究，其中首因效应和近因效应分别支持了长时记忆和短时记忆的存在。
6. Development: Attachment Theory | 发展心理学：依恋理论
Attachment is a strong emotional bond between an infant and a caregiver. John Bowlby proposed that attachment is innate and adaptive, helping infants survive. He suggested that infants have a critical period (around the first 2-3 years) for forming attachments, and that this early bond forms an internal working model for future relationships.
依恋是婴儿与照护者之间强烈的情感纽带。John Bowlby 提出依恋是与生俱来的、适应性的，有助于婴儿生存。他认为婴儿有一个形成依恋的关键期（大约在出生后的前2-3年），而这种早期纽带会形成未来关系的内部工作模型。
Mary Ainsworth’s Strange Situation procedure identified three main attachment types: secure (type B), insecure-avoidant (type A), and insecure-resistant (type C). In the UK, around 60-70% of infants are classified as securely attached. A secure attachment is associated with a caregiver who is sensitive and responsive.
Mary Ainsworth 的’陌生情境’程序识别了三种主要的依恋类型：安全型（B型）、不安全-回避型（A型）和不安全-反抗型（C型）。在英国，约60-70%的婴儿被归类为安全型依恋。安全型依恋与照护者的敏感性和回应性相关。
Bowlby also emphasised that maternal deprivation – prolonged separation from the primary attachment figure – can have long-term emotional and social consequences, such as affectionless psychopathy. This highlights the importance of early caregiving relationships.
Bowlby 还强调，母性剥夺 – 与主要依恋对象的长期分离 – 可能产生长期的情绪和社交后果，如冷漠型精神病态。这突显了早期照护关系的重要性。
7. Social Influence: Conformity | 社会影响：从众
Conformity is a change in a person’s behaviour or opinions as a result of real or imagined pressure from a person or group. Solomon Asch (1951) conducted a line judgment experiment where participants often conformed to the incorrect answer given by a unanimous majority, even when the correct answer was obvious. The average conformity rate was about 37%.
从众是指个人因真实或想象的人或群体压力而改变行为或观点的现象。Solomon Asch（1951）进行了一项线段判断实验，参与者在明显正确答案的情况下，常常随声附和绝大多数人的错误答案，平均从众率约为37%。
Normative social influence occurs when we conform to be liked or accepted by the group; in Asch’s study, conformity dropped significantly when participants wrote their answers down instead of saying them aloud. Informational social influence happens when we conform because we believe the group has more knowledge, especially in ambiguous situations.
规范社会影响发生在我们为了被群体喜欢或接受而顺从时；在Asch的研究中，当参与者写下答案而不是大声说出时，从众率显著下降。信息社会影响则发生在我们因为相信群体掌握更多信息而顺从时，特别是在情境模糊的情况下。
Factors affecting conformity include group size (conformity increases up to around 3-5 people), unanimity (if one other person dissents, conformity drops sharply), and task difficulty (harder tasks increase informational influence).
影响从众的因素包括群体规模（从众率随人数增加直到3-5人左右）、一致性（如果有一人持不同意见，从众率骤降）和任务难度（任务越难，信息性影响越大）。
8. Social Influence: Obedience | 社会影响：服从
Obedience involves following a direct order from an authority figure. Stanley Milgram’s (1963) electric shock experiment showed that 65% of participants were willing to deliver what they believed were dangerous 450-volt shocks to a ‘learner’ when instructed by an experimenter in a lab coat.
服从涉及听从权威人物的直接命令。Stanley Milgram（1963）的电击实验表明，当穿着白大褂的实验者发出指令时，65%的参与者愿意对’学习者’实施他们认为危险的450伏电击。
Milgram identified several situational factors affecting obedience: the proximity of the authority figure (obedience decreased when the experimenter gave orders by phone), proximity of the victim (obedience fell when the learner was in the same room), and the presence of disobedient peers. The prestige of the setting (Yale University) also increased obedience.
Milgram指出了影响服从的几种情境因素：权威人物的接近性（实验者通过电话下令时服从率下降）、受害者的接近性（学习者在同一房间时服从率下降），以及不服从同伴的存在。场所的声望（耶鲁大学）也增加了服从程度。
This research demonstrates that ordinary people can commit harmful acts under the pressure of an authority figure. The agentic state theory suggests individuals shift from an autonomous state to an agentic state, where they see themselves as agents carrying out someone else’s wishes and thus feel less personal responsibility.
这项研究表明，普通人在权威人物的压力下也能做出伤害行为。代理状态理论认为，个体从自主状态转变为代理状态，把自己看作执行他人意愿的代理人，从而减少了个人责任感。
9. Individual Differences: Phobias | 个体差异：恐惧症
A phobia is an intense, irrational fear of a specific object, activity, or situation that is out of proportion to the actual danger. To be diagnosed as a phobia, the fear must interfere with daily life and persist for at least six months. Phobias are classified into categories: specific phobia (e.g. spiders, heights), social phobia (fear of social judgment), and agoraphobia (fear of open or crowded spaces).
恐惧症是对某种特定物体、活动或情境的强烈、非理性恐惧，且与实际危险不成比例。要被诊断为恐惧症，这种恐惧必须干扰日常生活并持续至少六个月。恐惧症分为几类：特定恐惧症（如蜘蛛、高处）、社交恐惧症（害怕社交评价）和广场恐惧症（害怕开放或拥挤的空间）。
Symptoms of phobias can be behavioural (e.g. avoidance, freezing or fainting), emotional (e.g. extreme anxiety, panic), and cognitive (e.g. irrational thoughts, difficulty concentrating when exposed to the feared stimulus). The behavioural component is often the most visible.
恐惧症的症状可分为行为方面（如回避、僵住或晕倒）、情绪方面（如极度焦虑、恐慌）和认知方面（如非理性想法、暴露于恐惧刺激时难以集中注意力）。行为表现通常最为明显。
The two-process model explains phobias through classical and operant conditioning. A phobia is acquired when a neutral stimulus becomes associated with a fear response (classical conditioning), and it is maintained because avoidance reduces anxiety, which is negatively reinforcing (operant conditioning).
双过程模型通过经典条件反射和操作性条件反射解释恐惧症。当一种中性刺激与恐惧反应建立联结时，恐惧症就习得了（经典条件反射）；而由于回避行为能减少焦虑，这种回避就得到了负强化，从而使恐惧症得以维持（操作性条件反射）。
10. Data Handling and Analysis | 数据处理与分析
After collecting data, psychologists use descriptive statistics to summarise the findings. Measures of central tendency include the mean (average), median (middle value), and mode (most frequent value). The mean is most sensitive but can be distorted by outliers; the median is more robust for skewed data.
收集数据后，心理学家使用描述性统计来总结结果。集中趋势的度量包括平均数（平均值）、中位数（中间值）和众数（出现频率最高的值）。平均数最为灵敏但易受异常值影响；对于偏态数据，中位数更加稳健。
Measures of dispersion indicate how spread out the data are. The range is the difference between the highest and lowest values, while the standard deviation shows the average distance of each data point from the mean. A small standard deviation means the data are tightly clustered around the mean.
离散程度的度量显示数据的分散程度。极差是最大值与最小值之差，而标准差则表明每个数据点与平均值的平均距离。标准差小意味着数据紧密聚集在平均值周围。
Data can be presented using bar charts (for categorical data), histograms (for continuous data with equal intervals), and scattergraphs (to show relationships between co-variables). Outliers should be identified and discussed in terms of their impact on the conclusions.
数据可以使用条形图（用于分类数据）、直方图（用于等距连续数据）和散点图（显示共变量之间的关系）来呈现。应当识别异常值，并讨论它们对结论的影响。
Understanding the difference between qualitative and quantitative data is essential. Quantitative data are numerical and easier to analyse statistically, while qualitative data are non-numerical and rich in detail, often gathered from interviews or open-ended questions.
理解质性数据和量化数据的区别至关重要。量化数据是数字化的，更容易进行统计分析；而质性数据是非数字化的，细节丰富，通常通过访谈或开放式问题收集。
