This article pulls together the essential knowledge you need, covering everything from brain functions and memory to social influence and research methods. Each section is broken into bite-sized English–Chinese pairs to help you master the key ideas in both languages.
心理学是对心智和行为的科学研究。对于学习CCEA课程的八年级学生来说，它意味着探索我们如何思考、感受、学习以及与人互动。这篇文章汇集了你需要掌握的核心知识，涵盖从大脑功能、记忆到社会影响和研究方法的所有内容。每个部分都以简短的中英对照形式呈现，帮助你用两种语言掌握关键概念。
1. What Is Psychology? | 什么是心理学？
Psychology is defined as the scientific study of behaviour and mental processes. Behaviour includes any action we can observe, like talking or running, while mental processes refer to private thoughts, emotions and memories that cannot be seen directly.
心理学被定义为对行为和心理过程的科学研究。行为包括我们可以观察到的任何动作，比如说话或跑步，而心理过程则指无法直接看到的私人想法、情绪和记忆。
Psychologists use the scientific method to form research questions, collect data and test hypotheses. This separates psychology from everyday guessing or folk wisdom.
心理学家使用科学方法来形成研究问题、收集数据并检验假设。这让心理学区别于日常猜测或民间智慧。
The field has many branches. Biological psychology looks at the brain and nervous system; cognitive psychology studies thinking, memory and language; developmental psychology explores how people grow and change throughout life; and social psychology examines how we are influenced by others.
这个领域有许多分支。生理心理学关注大脑和神经系统；认知心理学研究思维、记忆和语言；发展心理学探索人们在一生中如何成长和变化；社会心理学则考察我们如何受他人影响。
2. The Brain and Behaviour | 大脑与行为
The brain is the main control centre of the human body. It contains billions of nerve cells called neurons that communicate using electrical and chemical signals.
大脑是人体的主要控制中心。它含有数十亿个称为神经元的神经细胞，这些细胞通过电信号和化学信号进行交流。
The cerebral cortex is divided into four lobes, each with specialised functions. The frontal lobe deals with planning, decision-making and personality. The parietal lobe processes touch, temperature and body position. The occipital lobe is dedicated to vision, and the temporal lobe handles hearing, language and some aspects of memory.
大脑皮层分为四个叶，每个都有专门的功能。额叶负责计划、决策和人格。顶叶处理触觉、温度和身体位置。枕叶专司视觉，而颞叶负责听觉、语言和某些记忆方面。
Neurotransmitters are chemical messengers that carry signals across the tiny gap between neurons (the synapse). For example, dopamine is linked to pleasure and motivation, while serotonin affects mood and sleep.
神经递质是化学信使，在神经元之间微小的间隙（突触）中传递信号。例如，多巴胺与愉悦和动机有关，而血清素影响情绪和睡眠。
3. Memory: How We Remember | 记忆：我们如何记忆
Memory is the process of encoding, storing and later retrieving information. Encoding turns sensory input into a code the brain can use; storage holds the information over time; retrieval accesses it when needed.
记忆是对信息进行编码、存储和随后提取的过程。编码将感觉输入转化为大脑可用的代码；存储将信息保留一段时间；提取则在需要时取得信息。
According to the multi-store model, memory has three separate stores. Sensory memory holds very brief impressions (a few seconds). Short-term memory (STM) can hold around 5–9 items for about 20–30 seconds, especially if we rehearse the information. Long-term memory (LTM) has a huge capacity and can store information almost permanently.
根据多存储模型，记忆有三个独立的存储器。感觉记忆保存非常短暂的印象（几秒钟）。短时记忆可以保存大约5到9个项目，持续约20到30秒，尤其在我们复述信息的时候。长时记忆容量巨大，几乎可以永久储存信息。
Long-term memory is often divided into procedural memory (skills, like riding a bike), semantic memory (facts and knowledge) and episodic memory (personal experiences).
长时记忆通常分为程序性记忆（技能，如骑自行车）、语义记忆（事实和知识）和情景记忆（个人经历）。
4. Forgetting and Memory Errors | 遗忘与记忆错误
Forgetting does not always mean a memory has disappeared. Sometimes the information was never properly encoded in the first place. In other cases, it decays over time or is displaced from short-term memory by new information.
遗忘并不总意味着记忆消失了。有时信息一开始就没有被恰当地编码。有时它会随着时间衰退，或被新信息从短时记忆中排挤出去。
Interference theory suggests that memories can get confused. Proactive interference happens when old learning disrupts new memories; retroactive interference is when new learning disrupts recall of old memories.
干扰理论认为记忆可能会相互混淆。前摄干扰发生在新记忆被旧学习干扰时；倒摄干扰则是在新学习干扰对旧记忆的回忆时。
Memory is not like a video recording. It can be reconstructed and altered. In eyewitness testimony research, Elizabeth Loftus showed that leading questions can change what people remember, demonstrating the fragile nature of memory.
记忆并不像录像一样。它可以被重构和改变。在目击证人证词研究中，伊丽莎白·洛夫特斯表明引导性问题可以改变人们的记忆，这证明了记忆的脆弱性。
5. Classical Conditioning: Learning by Association | 经典条件反射：通过联想学习
Classical conditioning was first described by Ivan Pavlov in his famous experiment with dogs. It is a type of learning in which a neutral stimulus becomes associated with a meaningful stimulus and eventually triggers a similar response.
经典条件反射最初由伊万·巴甫洛夫在他著名的狗实验中提出。这是一种学习类型，其中一个中性刺激与一个有意义的刺激关联起来，最终引发类似的反应。
In Pavlov’s study, food was the unconditioned stimulus (US) that naturally caused salivation (unconditioned response, UR). The sound of a bell was a neutral stimulus. After repeatedly pairing the bell with food, the bell alone became a conditioned stimulus (CS) that produced salivation – now called the conditioned response (CR).
在巴甫洛夫的研究中，食物是能够自然引起唾液分泌（非条件反应）的非条件刺激。铃声是一个中性刺激。在反复将铃声与食物配对之后，铃声本身成了一个条件刺激，引起唾液分泌——此时称为条件反应。
Important concepts include generalisation (responding to similar stimuli), discrimination (not responding to dissimilar stimuli) and extinction (the conditioned response fading when the CS is no longer paired with the US).
重要的概念包括泛化（对类似刺激做出反应）、分化（不对不相似的刺激做出反应）和消退（当条件刺激不再与非条件刺激配对时，条件反应逐渐减弱）。
6. Operant Conditioning: Learning from Consequences | 操作性条件反射：从后果中学习
Operant conditioning, developed by B.F. Skinner, explains how we learn from the consequences of our actions. Behaviour is shaped and maintained by reinforcements and punishments.
操作性条件反射由斯金纳提出，解释了我们如何从行为的后果中学习。行为通过强化和惩罚被塑造并维持。
Positive reinforcement means adding a pleasant stimulus to strengthen a behaviour, such as giving a reward for completing homework. Negative reinforcement means removing an unpleasant stimulus to strengthen behaviour, like taking a painkiller to relieve a headache – the behaviour of taking medicine is reinforced by the headache going away.
正强化指增加一个愉快的刺激以增强行为，例如由于完成作业而给予奖励。负强化指移除一个不愉快的刺激以增强行为，例如服用止痛药来减轻头痛——服药的行为因为头痛消失而得到强化。
Punishment aims to weaken behaviour. Positive punishment adds something unpleasant (e.g., a scolding), while negative punishment removes something pleasant (e.g., losing phone privileges).
惩罚旨在削弱行为。正惩罚增加一些不愉快的东西（例如责骂），而负惩罚则移除一些愉快的东西（例如失去使用手机的权利）。
7. Observational Learning: Learning by Watching | 观察学习：通过观察学习
Albert Bandura’s social learning theory emphasises that we can learn new behaviours simply by observing others. This is called observational learning or modelling.
阿尔伯特·班杜拉的社会学习理论强调，我们仅仅通过观察他人就能学会新行为。这被称为观察学习或模仿。
In the famous Bobo doll experiment, children watched an adult being aggressive towards an inflatable doll. Later, many of those children imitated the aggressive acts, especially if they saw the adult being rewarded. This showed that reinforcement is not always direct.
在著名的波波玩偶实验中，儿童观看一个成年人对充气玩偶做出攻击行为。后来，许多儿童模仿了这些攻击行为，尤其是当他们看到那个成人因此受到奖励时。这表明强化并不总是直接的。
Bandura proposed four key steps for observational learning: attention (paying notice to the model), retention (remembering what was observed), reproduction (having the ability to copy the behaviour) and motivation (wanting to imitate, perhaps because of rewards).
班杜拉提出了观察学习的四个关键步骤：注意（关注示范者）、保持（记住所观察到的）、复制（有能力重现该行为）和动机（出于奖励等原因想要模仿）。
8. Emotions and Motivation | 情绪与动机
Emotions are complex feelings that involve physiological arousal, expressive behaviours and conscious experience. Basic emotions include happiness, sadness, fear, anger, surprise and disgust.
情绪是涉及生理唤醒、表达行为和意识体验的复杂感受。基本情绪包括快乐、悲伤、恐惧、愤怒、惊讶和厌恶。
The James-Lange theory suggests that we experience emotion because we notice bodily changes. For example, we feel afraid because our heart is racing. In contrast, the Cannon-Bard theory says that the bodily reaction and the emotional experience happen at the same time.
詹姆斯-兰格理论认为我们体验到情绪是因为我们注意到了身体变化。例如，我们感到害怕是因为心跳加速。相反，坎农-巴德理论则认为身体反应和情绪体验是同时发生的。
Motivation refers to the drives that direct our behaviour towards goals. Abraham Maslow’s hierarchy of needs arranges human motives from basic biological needs (food, safety) up to self-actualisation – the desire to reach one’s full potential.
动机指引导我们行为朝向目标的驱动力。亚伯拉罕·马斯洛的需求层次理论将人类动机从基本的生理需求（食物、安全）一直排列到自我实现——即发挥全部潜能的愿望。
9. Personality: What Makes You Unique? | 人格：是什么让你独一无二？
Personality describes an individual’s characteristic pattern of thinking, feeling and behaving. Psychologists often use the Big Five model, which includes openness, conscientiousness, extraversion, agreeableness and neuroticism (OCEAN for short).
人格描述了一个人独特的思维、感受和行为模式。心理学家常使用大五模型，其中包括开放性、尽责性、外向性、宜人性和神经质（简称OCEAN）。
Openness involves curiosity and a willingness to try new things. Conscientiousness refers to being organised and dependable. Extraversion is about sociability and energy. Agreeableness reflects kindness and cooperation. Neuroticism indicates emotional instability and a tendency to experience negative feelings.
开放性涉及好奇心和愿意尝试新事物。尽责性指有条理且可靠。外向性与社交性和活力有关。宜人性反映了友善与合作。神经质则表示情绪不稳定以及体验负面感受的倾向。
Sigmund Freud described the mind as having three parts: the id (basic drives and impulses), the ego (the rational part that balances the id and reality) and the superego (the moral conscience). While modern psychology does not fully accept this model, it remains a useful historical idea.
西格蒙德·弗洛伊德将心理描述为有三个部分：本我（基本驱力和冲动）、自我（平衡本我与现实的理性部分）和超我（道德良知）。虽然现代心理学并不完全接受这一模型，但它仍是一个有用的历史概念。
10. Social Influence: Conformity and Obedience | 社会影响：从众与服从
Social influence looks at how our thoughts, feelings and actions are affected by other people. Two key forms are conformity (going along with a group) and obedience (following direct orders from an authority figure).
社会影响考察我们的思想、感受和行为如何受到他人的影响。两种主要形式是从众（随大流）和服从（遵从权威人物的直接命令）。
Solomon Asch’s line-judging experiment revealed the power of conformity. Even when the correct answer was obvious, many participants gave an obviously wrong answer just because the rest of the group did so. This showed the pull of normative social influence – the desire to fit in.
所罗门·阿希的线段判断实验揭示了从众的力量。即使正确答案显而易见，许多参与者仍然仅仅因为小组其他人那么回答，就给出了明显错误的答案。这显示了规范性社会影响的拉力——渴望融入群体。
Stanley Milgram’s obedience study, meanwhile, found that ordinary people could be instructed to deliver what they thought were painful electric shocks to a learner, simply because an authority figure told them to. The experiment highlighted how situational factors, such as proximity to the authority, can dramatically affect obedience levels.
与此同时，斯坦利·米尔格拉姆的服从研究发现，普通人可以被指示对学习者施加他们相信是痛苦的电击，仅仅因为权威人物让他们这样做。这个实验突出了情境因素（如与权威的距离）如何极大地影响服从程度。
11. Research Methods in Psychology (Basic) | 心理学研究方法（基础）
Psychologists use various methods to investigate behaviour. The experimental method is particularly important because it allows researchers to establish cause–effect relationships. In an experiment, the independent variable (IV) is what the researcher changes, and the dependent variable (DV) is what is measured.
心理学家使用各种方法来研究行为。实验法尤为重要，因为它让研究者能够建立因果关系。在实验中，自变量是研究者改变的变量，因变量则是测量的变量。
A well-designed experiment controls extraneous variables so that any change in the DV can be confidently attributed to the IV. Participants are often randomly allocated to different conditions to reduce bias.
精心设计的实验会控制额外变量，以便任何因变量的变化都能确信是由自变量引起的。参与者通常会被随机分配到不同条件中，以减少偏差。
Other methods include naturalistic observation (watching behaviour without interference), surveys and questionnaires (collecting self-reported data) and correlational studies (looking for relationships between two variables, though correlation does not imply causation).
其他方法包括自然观察（在不加干扰的情况下观察行为）、调查和问卷（收集自我报告的数据）以及相关研究（寻找两个变量之间的关系，尽管相关并不意味着因果关系）。
12. Ethics in Psychology | 心理学中的伦理
When conducting research with human participants, psychologists must follow strict ethical guidelines to protect people’s wellbeing. Key principles include informed consent, the right to withdraw, confidentiality, protection from harm and debriefing after the study.
在进行涉及人类参与者的研究时，心理学家必须遵循严格的伦理准则以保护人们的福祉。关键原则包括知情同意、随时退出的权利、保密、免受伤害以及研究后的脱敏简报。
Informed consent means that participants should fully understand what the study involves and agree to take part voluntarily. If children or vulnerable people are involved, consent must be obtained from parents or guardians.
知情同意意味着参与者应充分理解研究涉及什么并自愿同意参加。如果涉及儿童或易受伤害的人，则必须获得父母或监护人的同意。
Deception should be avoided unless it is absolutely necessary for the research. If used, the researcher must tell participants the truth afterward during debriefing. The goal is to balance the pursuit of knowledge with the dignity and safety of every individual.
欺骗应避免，除非研究绝对必要。如果使用了欺骗，研究者必须在之后的脱敏简报中告知参与者真相。其目标是平衡对知识的追求与每个个体的尊严和安全。
