本指南旨在帮助你在这个暑期探索迷人的心理学世界。你将了解什么是心理学、心理学家如何进行科研，并预习你在Edexcel课程中将涵盖的关键主题。
1. What is Psychology? | 什么是心理学？
Psychology is the scientific study of the mind, brain, and behaviour. It uses evidence-based methods to answer questions about why people act, think, and feel the way they do.
心理学是对心理、大脑和行为的科学研究。它使用基于证据的方法来回答关于人们为何会有某种行为、思维和感受的问题。
Unlike common sense, psychology relies on controlled experiments and observations to test theories and uncover patterns.
与常识不同，心理学依赖受控实验和观察来检验理论并揭示模式。
2. The Goals of Psychological Research | 心理学研究的目标
Psychology has four main goals: describe, explain, predict, and change behaviour.
心理学有四个主要目标：描述、解释、预测和改变行为。
Description involves carefully observing and recording what is happening, such as noting how children play in a playground.
描述涉及仔细观察和记录正在发生的事情，例如注意孩子们在游乐场如何玩耍。
Explanation seeks to understand the causes of behaviour, for example, why some students perform better under pressure.
解释旨在理解行为的原因，例如为什么有些学生在压力下表现更好。
Prediction uses what we know to forecast future behaviour, like predicting who might develop a fear of exams.
预测运用已知来预报未来的行为，比如预测谁可能产生考试恐惧。
Finally, change means applying psychological principles to improve lives, such as using relaxation techniques to reduce anxiety.
最后，改变意味着应用心理学原理来改善生活，例如使用放松技巧减少焦虑。
3. The Scientific Method in Psychology | 心理学中的科学方法
Psychologists follow a scientific process: ask a question, form a hypothesis, design a study, collect data, analyse results, and draw a conclusion.
心理学家遵循科学过程：提出问题，形成假设，设计研究，收集数据，分析结果，得出结论。
A hypothesis is a testable prediction, for instance, "Students who sleep 8 hours will recall more words than those who sleep 4 hours."
假设是一个可检验的预测，例如，"睡8小时的学生会比睡4小时的学生记住更多单词"。
Key variables are manipulated and measured: the independent variable (IV) is what the researcher changes, and the dependent variable (DV) is what is measured.
关键变量被操纵和测量：自变量（IV）是研究者改变的因素，因变量（DV）是被测量的结果。
Control of extraneous variables is important so that the study measures what it intends to measure.
控制无关变量很重要，这样研究才能测量它要测量的东西。
4. Key Research Methods | 关键研究方法
Psychologists use different methods depending on the research question. Here are some common ones.
心理学家根据研究问题使用不同的方法。以下是一些常见的方法。
| Method (English) | 方法 (中文) |
|---|---|
| Experiment – manipulates the IV while controlling other variables to measure the DV | 实验 – 操纵自变量，同时控制其他变量来测量因变量 |
| Observation – watching and recording behaviour in a natural or controlled setting | 观察 – 在自然或受控环境中观察和记录行为 |
| Questionnaire – a set of written questions to gather self-reported data | 问卷 – 一组书面问题，用于收集自我报告数据 |
| Interview – a conversation where the researcher asks questions to explore thoughts and feelings | 访谈 – 研究者通过提问来探讨想法和感受的对话 |
| Case study – an in-depth investigation of a single person, group, or event | 个案研究 – 对单个人、群体或事件的深入调查 |
5. Ethical Guidelines | 伦理准则
All psychological research must follow ethical standards to protect participants from harm and ensure trust.
所有心理学研究都必须遵循伦理标准，以保护参与者免受伤害并确保信任。
Informed consent: Participants must understand what the study involves and agree to take part voluntarily.
知情同意：参与者必须理解研究内容并自愿同意参加。
Deception should be avoided, but if used, it must be justified and followed by debriefing.
应避免欺骗，但如果使用，必须有正当理由并在事后进行解说。
Debriefing: After the study, participants are told the true purpose and any deception is explained.
事后解说：研究结束后，告知参与者真实目的并解释任何欺骗。
Confidentiality: Personal information must be kept private and not shared without permission.
保密：个人信息必须保密，未经许可不得分享。
Right to withdraw: Participants can leave the study at any time without penalty.
退出权利：参与者可以在任何时间退出研究而不受惩罚。
6. Introduction to Memory | 记忆入门
Memory is the process of encoding, storing, and retrieving information. Psychologists describe different types of memory stores.
记忆是编码、存储和提取信息的过程。心理学家描述了不同类型的记忆存储。
The multi-store model suggests information flows from sensory memory to short-term memory (STM) and then to long-term memory (LTM).
多存储模型表明信息从感觉记忆流向短时记忆（STM），然后到长时记忆（LTM）。
STM has a limited capacity of about 7±2 items and a short duration unless rehearsed.
短时记忆容量有限，大约7±2个项目，持续时间短，除非进行复述。
LTM has a potentially unlimited capacity and can store memories for a lifetime. Rehearsal helps transfer information from STM to LTM.
长时记忆容量几乎无限，可以终生存储记忆。复述有助于将信息从短时记忆转移到长时记忆。
7. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Social influence examines how others affect our thoughts, feelings, and actions.
