1. What is Psychology? | 什么是心理学？
Psychology is the scientific study of the mind and behaviour. It seeks to understand why individuals think, feel, and act in certain ways by using systematic research methods rather than relying on intuition or common sense. Psychologists explore both observable actions and internal mental processes like memory, emotion, and decision-making.
心理学是关于心智与行为的科学研究。它旨在通过系统的研究方法（而非依赖直觉或常识）来理解个体为何以特定方式思考、感受和行动。心理学家探索可观察的行为以及记忆、情绪和决策等内部心理过程。
2. The Scientific Method in Psychology | 心理学中的科学方法
To investigate behaviour objectively, psychologists follow the scientific method. This involves forming a hypothesis based on existing theories, designing a controlled study, collecting and analysing data, and drawing conclusions. The aim is to produce valid, replicable findings that add to our understanding of human behaviour. Objectivity, reliability, and falsifiability are key principles.
为了客观地研究行为，心理学家遵循科学方法。这包括根据现有理论提出假设，设计控制性研究，收集并分析数据，然后得出结论。其目的在于产生有效、可重复的研究发现，以加深我们对人类行为的理解。客观性、可靠性和可证伪性是关键原则。
3. Variables and Research Designs | 变量与研究设计
Every experiment involves variables. The independent variable (IV) is the factor the researcher deliberately changes. The dependent variable (DV) is the factor that is measured to see if it has changed as a result. All other variables must be controlled so they do not become confounding variables. Common research designs include independent groups, repeated measures, and matched pairs, each with its own strengths and limitations in controlling participant variables and order effects.
每个实验都涉及变量。自变量（IV）是研究者有意改变的因素。因变量（DV）是为了观察其是否因自变量而改变而测量的因素。所有其他变量必须加以控制，以避免成为混淆变量。常见的研究设计包括独立组设计、重复测量设计和匹配对设计，每种设计在控制参与者变量和顺序效应方面各有优缺点。
4. Ethical Considerations | 伦理考量
All psychological research must follow strict ethical guidelines to protect participants. Key ethical principles include obtaining informed consent, avoiding deception where possible, protecting participants from physical and psychological harm, respecting the right to withdraw at any time, and maintaining confidentiality. Researchers must also debrief participants after the study, explaining the true purpose of the research.
所有心理学研究都必须遵循严格的伦理准则以保护参与者。关键的伦理原则包括：获得知情同意、尽可能避免欺骗、保护参与者免受身心伤害、尊重其随时退出的权利以及保持保密性。研究者还必须在研究结束后对参与者进行事后解释，告知研究的真实目的。
5. Memory: The Multi-Store Model | 记忆：多存储模型
n a linear fashion. Sensory memory holds a fleeting copy of sensory input for a fraction of a second. If we pay attention to it, the information moves to short-term memory (STM), which has a limited capacity of about 7±2 chunks and a duration of around 18-30 seconds without rehearsal. Through elaborative rehearsal, information can be encoded into long-term memory (LTM), where it can potentially remain for a lifetime.
阿特金森和希夫林（1968）提出了记忆的多存储模型，描述了信息以线性方式经过的三个独立存储库。感觉记忆将感官输入的短暂副本保持不到一秒。如果我们加以注意，信息就会进入短时记忆（STM），其容量有限，约为 7±2 个组块，在不复述的情况下保持时间约 18-30 秒。通过精细复述，信息可以编码进入长时记忆（LTM），并可能保持终生。
| Store 存储 | Capacity 容量 | Duration 持续时间 | Coding 编码 |
|---|---|---|---|
| Sensory 感觉 | Very large 非常大 | Less than 1 second 少于 1 秒 | Modality-specific 模态特异 |
| Short-term 短时 | 7 ± 2 chunks 组块 | 18-30 seconds 秒 | Largely acoustic 主要为听觉 |
| Long-term 长时 | Potentially unlimited 可能无限 | Lifetime 终生 | Semantic 语义 |
The model has been supported by case studies such as HM, who lost the ability to form new long-term memories after brain surgery, yet his STM remained intact. This suggests the stores are distinct. However, critics argue the model oversimplifies memory, presenting it as too passive and failing to fully explain how different types of LTM interact.
该模型得到了 HM 等个案研究的支持，他在脑部手术后丧失了形成新长时记忆的能力，但短时记忆保持完整，这表明各个存储库是分离的。然而，批评者认为该模型过于简化了记忆，将其描绘得过于被动，且未能充分解释不同类型的长时记忆如何相互作用。
6. Factors Affecting Memory | 影响记忆的因素
Forgetting can occur due to interference, lack of rehearsal, or retrieval failure. Proactive interference is when old information disrupts the recall of new information, while retroactive interference is when new information disrupts old memories. Context and state also play a role: we recall information better if we are in the same physical environment or emotional state as when we first learned it.
遗忘可能由干扰、缺乏复述或提取失败造成。前摄干扰指旧信息干扰了新信息的回忆，而倒摄干扰指新信息干扰了旧记忆。情境和状态也发挥作用：当我们所处的物理环境或情绪状态与初次学习时相同时，我们能更好地回忆信息。
Another important phenomenon is reconstructive memory, particularly studied by Bartlett. He showed that memory is not a perfect recording but an active reconstruction influenced by schemas – mental frameworks based on past experience. When people recall a story, they often omit details, add elements, or change the sequence to make it fit their existing cultural expectations.
另一个重要现象是重构记忆，巴特利特对此进行了深入研究。他表明记忆不是完美的录像，而是一种主动重构，受图式——基于过去经验的心理框架——的影响。当人们回忆一个故事时，常常会省略细节、添加元素或改变顺序，使其符合自己已有的文化期望。
7. Attachment: Bowlby's Theory | 依恋：鲍尔比的理论
John Bowlby proposed that infants have an innate drive to form a strong emotional bond with a primary caregiver, usually the mother. This attachment is an evolutionary mechanism that ensures survival, as the caregiver provides protection and food. Bowlby introduced the concepts of the critical period (around the first 2.5 years during which the attachment system must develop) and monotropy, the idea that one primary attachment is more important than any other.
约翰·鲍尔比提出，婴儿天生具有与主要照料者（通常是母亲）形成强烈情感纽带的驱动力。这种依恋是一种确保生存的进化机制，因为照料者提供保护与食物。鲍尔比引入了关键期（大约最初的 2.5 年，依恋系统必须在此期间发展）和单一依恋的概念，即认为一个主要的依恋关系比其他任何依恋都更重要。
Disruption of this bond, he argued, could lead to irreversible consequences for the child's social and emotional development, known as maternal deprivation. His theory was influenced by studies of juvenile delinquents and the concept of the internal working model, a mental representation of relationships that guides future interactions.
他认为，这种纽带的破坏可能导致对儿童社交和情感发展不可逆的后果，即所谓母爱剥夺。他的理论受到少年罪犯研究的影响，并提出了内部工作模型的概念，这是一种指导未来人际关系的心智表征。
8. Ainsworth's Strange Situation | 安斯沃思的陌生情境法
Mary Ainsworth designed the Strange Situation, a controlled observation procedure to assess the quality of attachment between an infant and caregiver. The procedure involves a series of eight brief episodes, including separations and reunions with the caregiver, and the introduction of a stranger. Based on the infant's behaviour, Ainsworth identified three main attachment types: secure, insecure-avoidant, and insecure-resistant.
玛丽·安斯沃思设计了陌生情境法，这是一种用来评估婴儿与照料者之间依恋质量的控制性观察程序。该程序包括八个简短的场景，包含与照料者的分离与重聚以及陌生人的引入。根据婴儿的行为，安斯沃思确定了三种主要的依恋类型：安全型、不安全-回避型和不安全-反抗型。
- Secure attachment (Type B): The infant uses the caregiver as a safe base, shows distress when they leave, and is easily comforted upon reunion. 安全型（B 类）：婴儿将照料者当作安全基地，照料者离开时表现出痛苦，重聚时容易被安抚。
- Insecure-avoidant (Type A): The infant shows little distress on separation and avoids contact on reunion. 不安全-回避型（A 类）：婴儿在分离时几乎不表现痛苦，重聚时回避接触。
- Insecure-resistant (Type C): The infant is very distressed on separation and both seeks and resists comfort on reunion. 不安全-反抗型（C 类）：婴儿在分离时极度痛苦，重聚时既寻求又抗拒安慰。
This research highlighted the role of sensitive responsiveness in developing secure attachments. However, the procedure is limited by its cultural specificity, as expectations of independence and separation vary across societies.
这项研究凸显了敏感回应在发展安全依恋中的作用。然而，该程序受限于其文化特异性，因为不同社会对独立与分离的期望有所不同。
9. Social Influence: Conformity (Asch) | 社会影响：从众（阿希实验）
Solomon Asch (1951) conducted a classic experiment on conformity. Male college students were asked to match the length of a standard line to three comparison lines in a group where several confederates deliberately gave the same wrong answer. The real participant was seated so that they answered last or near last. About 75% of participants conformed to the incorrect majority at least once, showing the power of normative social influence – the desire to fit in.
所罗门·阿希（1951）进行了一项关于从众的经典实验。男性大学生被要求在小组中比对标准线段的长度与三条比较线段，组内有好几个同谋故意给出相同的错误答案。真被试被安排在最后或接近最后回答。大约 75% 的被试至少有一次屈从于多数人的错误意见，显示了规范性社会影响——希望融入群体的力量。
Asch found that conformity rates dropped sharply when there was just one dissenter, demonstrating the importance of social support in resisting group pressure. The study illustrates how even a clear, unambiguous physical judgment can be swayed by the need to avoid social disapproval.
阿希发现，只要有一个持异议者，从众率就会急剧下降，这表明了社会支持在抵抗群体压力中的重要性。这项研究说明，即便是清晰明确的身体判断也会因避免社会否定的需要而改变。
10. Obedience to Authority (Milgram) | 对权威的服从（米尔格拉姆实验）
Stanley Milgram (1963) set up a study to understand why people obey destructive orders. Participants were led to believe they were administering increasingly severe electric shocks to a learner (a confederate) for every mistake. Despite the learner’s protests and eventual silence, 65% of participants continued to the maximum 450-volt shock when prompted by an authority figure in a lab coat.
斯坦利·米尔格拉姆（1963）设计了一项研究以理解人们为何服从破坏性的命令。参与者被告知他们将对犯错的学习者（同谋）施加不断增强的电击。尽管学习者发出抗议并最终沉默，仍有 65% 的参与者在穿白大褂的权威人物催促下继续施加最高 450 伏的电击。
Milgram concluded that ordinary people could commit harmful acts when placed in an agentic state – seeing themselves as merely carrying out orders for an authority figure. Situational factors such as proximity of the authority, prestige of the setting, and the presence of disobedient peers significantly affected obedience levels. The study raised serious ethical concerns but remains a powerful demonstration of social power.
米尔格拉姆得出结论，当普通人处于代理状态——视自己仅为执行权威人物命令的工具时，他们可能做出伤害行为。情境因素，如权威的接近性、环境的声望以及是否有不服从的同伴在场，显著影响服从水平。该研究引发了严重的伦理关切，但至今仍是社会力量的有力展示。
11. Prosocial and Antisocial Behaviour | 亲社会与反社会行为
Prosocial behaviour is voluntary action intended to help others. The bystander effect, studied by Latane and Darley, shows that people are less likely to help a victim when others are present, due to diffusion of responsibility and fear of social embarrassment. Increasing prosocial behaviour can be encouraged by teaching empathy and modelling helpfulness.
亲社会行为是旨在帮助他人的自愿行为。拉坦内和达利研究的旁观者效应表明，当有其他人在场时，人们帮助受害者的可能性更低，这是由于责任分散和害怕社会尴尬。可透过教授共情和示范助人行为来促进亲社会行为。
Antisocial behaviour, such as aggression, can be influenced by biological factors (e.g., testosterone), social learning (observing aggressive role models), and environmental triggers (frustration, heat). Deindividuation, where a person loses their sense of individual identity in a crowd, can also lower inhibitions against antisocial acts.
反社会行为，如攻击性，可能受生物因素（如睾酮）、社会学习（观察攻击性榜样）和环境诱因（挫折、高温）的影响。去个性化，即个体在人群中丧失自我认同感，也可能降低对反社会行为的抑制。
12. Key Terms and Application | 关键术语与应用
To succeed in Year 9 WJEC Psychology, you must be confident with the language of the subject. This includes being able to define and apply terms such as independent variable, dependent variable, extraneous variable, ecological validity, sample, target population, ethical guidelines, schema, internal working model, normative social influence, agentic state, and diffusion of responsibility. Use these terms not only in definitions but also when evaluating studies and answering structured questions.
要在九年级 WJEC 心理学中取得成功，你必须自信地使用学科语言。这包括能够定义并应用诸如自变量、因变量、额外变量、生态效度、样本、目标总体、伦理准则、图式、内部工作模型、规范性社会影响、代理状态和责任分散等术语。不仅在给出定义时使用它们，还要在评价研究和回答结构化问题时使用。
Regular retrieval practice – such as drawing memory models, comparing attachment styles, or designing ethical mini-experiments – will strengthen your knowledge and prepare you well for both short-answer and extended writing questions.
定期进行提取练习——如绘制记忆模型、比较依恋类型或设计符合伦理的小型实验——将强化你的知识，并为简答题和论述题做好充分准备。
