📚 SQA Year 13 Media Studies: Quick Reference Handbook of Formulas and Theorems | SQA 13年级媒体：公式定理速查手册

This quick reference handbook compiles the essential theoretical frameworks, analytical ‘formulas’ and critical theorems that Year 13 SQA Media Studies candidates must master. From Lasswell’s communication chain to Hall’s encoding/decoding model, each entry distils a core media concept into a memorable structure, supported by its practical application in deconstructing texts, audiences and institutions.

本速查手册汇集了 SQA 13 年级媒体研究考生必须掌握的核心理论框架、分析“公式”与关键定理。从拉斯韦尔传播链条到霍尔的编码/解码模型，每一条目都将一个核心媒体概念浓缩为便于记忆的结构，并辅以在解构文本、受众与机构时的实际应用。

1. Lasswell’s Communication Model | 拉斯韦尔传播模式

Lasswell’s model breaks communication into five linear elements: Who (communicator) says What (message) in Which Channel (medium) to Whom (receiver) with What Effect (outcome). It serves as a foundational checklist for analysing any media artefact.

拉斯韦尔模型将传播拆解为五个线性要素：谁（传播者）说了什么（讯息）通过何种渠道（媒介）对谁（接收者）产生什么效果（结果）。它是分析任何媒体制品的基础清单。

Communicator – the institution or individual producing the message.
传播者 – 生产讯息的机构或个人。
Message – the content, codes and conventions used.
讯息 – 使用的内容、符码与惯例。
Medium – the platform or technology (TV, social media, press).
媒介 – 平台或技术（电视、社交媒体、报刊）。
Receiver – the active or passive audience.
接收者 – 主动或被动的受众。
Effect – intended or unintended impact on attitudes, beliefs or behaviour.
效果 – 对态度、信仰或行为的有意或无意影响。

2. Semiotic Triangle (Ogden & Richards) | 语义三角（奥格登与理查兹）

The semiotic triangle illustrates that a sign is composed of a symbol (word/image), a referent (real-world thing) and a thought/reference (mental concept). Meaning arises not from a direct link between symbol and referent but through our shared mental concept.

语义三角说明一个符号由符号（词语/图像）、指称对象（现实事物）和思想/指涉（心理概念）构成。意义并非产生于符号与指称对象的直接联系，而是通过我们共有的心理概念。

Symbol – the physical form of the sign, e.g. the word ‘dog’ or a photograph of a dog.
符号 – 符号的物质形式，例如“狗”这个词或一张狗的照片。
Referent – the actual animal in the world.
指称对象 – 现实世界中的真实动物。
Thought/Reference – the cultural idea of ‘dogness’ shared by a language community.
思想/指涉 – 语言社群共有的关于“狗性”的文化观念。

Applied to media, this triangle explains why the same image of a flag can evoke patriotism in one audience and oppression in another.

应用于媒体，这个三角解释了为什么同一面旗帜的图像会在一群受众中唤起爱国主义，在另一群中却唤起压迫感。

3. Todorov’s Narrative Equilibrium | 托多罗夫叙事平衡公式

Todorov proposed that all narratives follow a five-stage structure: equilibrium → disruption → recognition of disruption → attempt to repair → new equilibrium. This formula underpins countless film plots, news stories and advertising arcs.

托多罗夫提出所有叙事都遵循五阶段结构：平衡 → 打破平衡 → 识别打破 → 尝试修复 → 新平衡。这一公式支撑了无数电影情节、新闻故事和广告弧线。

Stage 1: Equilibrium – a stable, ordered world is established.
阶段一：平衡 – 建立一个稳定有序的世界。
Stage 2: Disruption – an event disturbs the order (villain, problem).
阶段二：打破 – 一个事件扰乱了秩序（反派、问题）。
Stage 3: Recognition – characters realise the disruption.
阶段三：识别 – 角色认识到打破。
Stage 4: Attempt to repair – the hero sets out to resolve the issue.
阶段四：尝试修复 – 英雄出发去解决问题。
Stage 5: New equilibrium – order is restored, but the world is changed.
阶段五：新平衡 – 秩序恢复，但世界已经改变。

4. Propp’s Character Functions | 普罗普角色功能

After analysing Russian folktales, Propp identified eight character types that perform 31 narrative functions. This ‘character formula’ helps analysts map the deep structure of media texts.

在分析俄罗斯民间故事后，普罗普识别出执行 31 种叙事功能的八种角色类型。这一“角色公式”帮助分析者描绘媒体文本的深层结构。

Character Type	Function
Hero	Seeks something, restores order
Villain	Opposes the hero, creates disruption
Donor	Gives the hero a magical object or advice
Helper	Aids the hero on the quest
Princess	Sought-for person, often the reward
Dispatcher	Sends the hero on the mission
False Hero	Claims credit, often unmasked
Father	Gives tasks, protects the princess

In modern media, a news broadcast can position a whistle-blower as the donor, the journalist as the hero and corrupt officials as villains.

在现代媒体中，一则新闻广播可以将吹哨人定位为捐助者、记者为英雄、腐败官员为反派。

5. Barthes’ Five Narrative Codes | 巴特五种叙事符码

Roland Barthes argued that every text is woven from five codes: the hermeneutic (enigma), proairetic (action), semantic (connotation), symbolic (oppositions) and cultural (reference to shared knowledge). Together they form a ‘grammar’ of storytelling.

罗兰·巴特认为每个文本都由五种符码编织而成：解释符码（谜团）、行动符码、语义符码（内涵）、象征符码（对立）和文化符码（对共有知识的引用）。它们共同构成叙事“语法”。

Hermeneutic Code – creates mystery; a question that drives the narrative forward.
解释符码 – 制造神秘；推动叙事向前发展的问题。
Proairetic Code – actions that imply further action (e.g. a character picking up a knife).
行动符码 – 暗示后续行动的动作（例如角色拿起一把刀）。
Semantic Code – elements that carry additional meaning through connotation.
语义符码 – 通过内涵承载额外意义的元素。
Symbolic Code – binary oppositions such as good/evil, light/dark.
象征符码 – 二元对立，如善/恶、光/暗。
Cultural Code – references to science, religion, history that the audience is expected to know.
文化符码 – 受众应当知道的科学、宗教、历史等引用。

6. Hall’s Encoding/Decoding Model | 霍尔编码/解码模型

Stuart Hall’s model states that media producers encode a preferred meaning into a text, but audiences decode it in three possible ways: dominant (accepting the intended message), negotiated (partly accepting, partly resisting) or oppositional (rejecting the intended meaning entirely). This ‘formula’ reveals the polysemic nature of media.

斯图尔特·霍尔的模型指出，媒体生产者将偏好意义编码进文本，但受众以三种可能方式解码：主导式（接受预期讯息）、协商式（部分接受、部分抵制）或对抗式（完全拒绝预期意义）。这一“公式”揭示了媒体的多义性。

Encoding → Text → Decoding (Dominant / Negotiated / Oppositional)

编码 → 文本 → 解码（主导 / 协商 / 对抗）

For example, a charity appeal video encoding ‘please donate’ may be accepted by dominant decoders, partially accepted by those who feel pity but are sceptical about aid, and rejected by oppositional decoders who see it as sentimental manipulation.

例如，一则编码为“请捐款”的慈善呼吁视频，主导式解码者会接受，协商式解码者（同情但怀疑援助有效性）部分接受，对抗式解码者则视其为情感操控而完全拒绝。

7. Uses and Gratifications Theory | 使用与满足理论

Instead of asking ‘what media do to people’, this theory asks ‘what people do with media’. It identifies four core needs that audiences actively satisfy: surveillance, personal identity, personal relationships and diversion. This turns audience behaviour into a predictable equation: Need + Media Choice = Gratification.

该理论不问“媒体对人做了什么”，而问“人们用媒体做什么”。它识别出受众主动满足的四种核心需求：监视、个人身份、人际关系和消遣。这将受众行为转化为一个可预测的等式：需求 + 媒体选择 = 满足。

Surveillance – acquiring information, keeping up with events (news, weather).
监视 – 获取信息，了解时事（新闻、天气）。
Personal Identity – reinforcing values, finding role models, identifying with characters.
个人身份 – 强化价值观、寻找榜样、与角色认同。
Personal Relationships – using media for companionship (parasocial) or as a social currency.
人际关系 – 用媒体陪伴（准社会关系）或作为社交货币。
Diversion – escapism, emotional release, relaxation.
消遣 – 逃避现实、情感宣泄、放松。

8. Reception Theory (Jauss and Iser) | 接受美学（姚斯和伊瑟尔）

Reception theory posits that meaning is not fixed within a text but is created in the encounter between text and reader. Two key concepts form the ‘reception formula’: horizon of expectations (the cultural and personal background the reader brings) and the implied reader (the ideal audience the text constructs).

接受美学假定意义并非固定在文本之内，而是在文本与读者的相遇中创造。两个关键概念构成了“接受公式”：期待视野（读者带来的文化与个人背景）和隐含读者（文本构建的理想受众）。

Horizon of Expectations – the set of assumptions, genre knowledge and life experience a reader uses to interpret a text. A shift in horizon can turn a comedy into a tragedy.
期待视野 – 读者用以解读文本的一组假设、类型知识和生活经验。视野的转变可以把喜剧变成悲剧。
Implied Reader – the reader a text anticipates; adverts for luxury cars imply a reader who aspires to status.
隐含读者 – 文本预设的读者；豪车广告暗示的是一位渴求地位的读者。

9. Representation Formula – Stereotypes and Archetypes | 再现公式 – 刻板印象与原型

Representation is the construction of reality through media. A simple formula captures how meaning is produced: Subject + Context + Codes = Representation. Stereotypes function as a ‘shortcut’ for audiences but can naturalise inequalities.

再现是通过媒体对现实的建构。一个简单公式捕捉了意义如何被生产：主体 + 语境 + 符码 = 再现。刻板印象充当受众的“捷径”，但可能将不平等自然化。

Selection – only certain aspects of a group are shown.
选择 – 只展示群体的某些方面。
Mediation – the message is shaped by the institution and medium.
中介 – 讯息被机构与媒介形塑。
Anchoring – captions or voiceovers fix a preferred meaning.
锚定 – 标题或画外音固定一个偏好意义。
Ideology – the dominant norms behind the representation.
意识形态 – 再现背后的主流规范。

Dyer’s typology of stereotypes reminds us that representations are always a simplification and an evaluation.

戴尔的刻板印象类型学提醒我们，再现永远是一种简化与一种评价。

10. Hegemony and Ideology (Gramsci) | 霸权与意识形态（葛兰西）

Hegemony explains why dominated groups consent to their own subordination not through force but through the diffusion of ruling-class ideas as ‘common sense’. The hegemony formula is: Dominant Ideology + Media Saturation + Taken-for-Grantedness = Cultural Consensus.

霸权解释了为何被统治群体并非通过武力，而是通过统治阶级思想被扩散为“常识”而同意自身的从属地位。霸权公式为：主导意识形态 + 媒体饱和 + 理所当然 = 文化共识。

Common Sense – media constantly present certain ideas (e.g. consumerism) as natural and inevitable.
常识 – 媒体不断将某些观念（如消费主义）呈现为自然而不可避免的。
Counter-hegemony – alternative media and social movements can challenge dominant common sense.
反霸权 – 另类媒体与社会运动可以挑战主导性常识。

11. Hypodermic Needle Theory | 皮下注射理论

Also called the magic bullet theory, this early effects model assumes that media messages are injected directly into a passive audience’s mind, producing uniform and immediate effects. Though largely discredited, it remains a useful benchmark to contrast with active audience theories.

又称魔弹论，这一早期的效果模型假设媒体讯息被直接注射进被动受众的大脑，产生统一且即时的效果。虽然已基本被否定，但它仍然是对比积极受众理论的有用参照。

Media Stimulus → Uniform Audience Response

媒体刺激 → 一致的受众反应

The theory is often invoked in moral panics surrounding violent video games and propaganda. Contemporary research shows audiences are far more selective and interpretive.

该理论常在围绕暴力电子游戏和宣传的道德恐慌中被提及。当代研究表明受众的选择性和解读力要强得多。

12. Two-Step Flow Theory (Lazarsfeld) | 两级传播理论（拉扎斯菲尔德）

Lazarsfeld found that media influence does not flow directly to the masses but is filtered through opinion leaders who interpret and pass on messages to their less active peers. The two-step formula is: Mass Media → Opinion Leader → Interpersonal Communication → Wider Audience.

拉扎斯菲尔德发现媒体影响并非直接流向大众，而是通过意见领袖过滤，他们将讯息解读并传递给较不活跃的同辈。两级传播公式为：大众媒体 → 意见领袖 → 人际传播 → 更广泛的受众。

Opinion Leaders – individuals who are more exposed to media, knowledgeable and trusted within their social circle.
意见领袖 – 更频繁接触媒体、知识渊博且在其社交圈内受信赖的个人。
Interpersonal Networks – the social relationships that mediate the eventual effect of media content.
人际网络 – 中介媒体内容最终效果的社会关系。
