This quick reference handbook breaks down the essential theories for Year 10 WJEC Media students into memorable ‘formulae’ and ‘theorems’, providing dual-language explanations to strengthen your understanding and exam performance.
在媒体研究中，虽然没有像物理学科那样的数学方程，但我们拥有强有力的“公式与定理”——即帮助我们分析媒体文本的概念模型。这本速查手册将 WJEC 十年级媒体课程的关键理论分解为易于记忆的“公式”和“定理”，并提供中英双语解释，以加深你的理解并提升考试成绩。
1. Saussure's Semiotic Sign Formula | 索绪尔的符号学公式
A sign is made of two inseparable parts: the signifier and the signified. The signifier is the physical form we see or hear, while the signified is the mental concept it triggers. When we put them together, we create meaning. This is the foundation of all media language analysis.
符号由两个不可分割的部分组成：能指和所指。能指是我们看到或听到的物质形式，而所指是它在脑中唤起的概念。当我们把它们结合起来，就产生了意义。这是所有媒体语言分析的基础。
Sign = Signifier (sound/image) + Signified (concept)
For example, a red rose (signifier) can signify romantic love (signified). Changing the signifier—a wilted rose—alters the signified to lost love. Media producers carefully select signifiers to convey precise meanings to audiences.
例如，一朵红玫瑰（能指）可以表示浪漫的爱情（所指）。改变能指——一朵枯萎的玫瑰——所指就转变为逝去的爱情。媒体制作人会精心选择能指，向受众传达精准的意义。
2. Peirce's Semiotic Triad Formula | 皮尔斯的符号三分法公式
Charles Sanders Peirce expanded semiotics by classifying signs into three types based on how the sign relates to its object. This triad helps us decode visual and audio codes in media products like posters, films and music videos.
查尔斯·桑德斯·皮尔斯扩展了符号学，根据符号与其对象的关系将符号分为三种类型。这个三分法帮助我们在海报、电影和音乐视频等媒体产品中解读视觉与听觉代码。
Sign Type = Icon (resemblance) OR Index (causal link) OR Symbol (learned convention)
Icon: A sign that physically resembles what it stands for, e.g. a portrait, a map, a smiley emoji.
图像符号：符号与它所代表的对象物理相似，例如肖像、地图、笑脸表情。
Index: A sign that has a direct causal or physical connection to its object, e.g. smoke indicating fire, a thermometer showing temperature, a scream suggesting fear.
指示符号：符号与其对象有直接的因果或物理联系，例如烟指示火、温度计显示温度、尖叫声暗示恐惧。
Symbol: A sign whose link to its object is arbitrary and must be culturally learned, e.g. a red cross for medical help, a dove for peace, words themselves.
象征符号：符号与对象的联系是任意的，必须通过文化学习，例如红十字代表医疗救助、鸽子代表和平、词语本身。
When analysing any media text, ask: does this sign rely on resemblance, a causal connection, or cultural convention? Most media messages blend all three.
在分析任何媒体文本时，问一问：这个符号依赖的是相似性、因果关系还是文化规约？大多数媒体信息混合了这三种类型。
3. Barthes' Myth and Connotation Formula | 巴特的神话与内涵公式
Roland Barthes showed how signs can operate on two levels to construct cultural myths. The first level is denotation (the literal ‘what’), the second is connotation (the associated meanings). Over time, dominant connotations become naturalised myths that shape our worldview.
罗兰·巴特展示了符号如何在两个层面上运作以构建文化神话。第一层是外延（字面上的“是什么”），第二层是内涵（相关联的意义）。随着时间的推移，主流内涵被自然化为塑造我们世界观的神话。
Denotation (1st Order Signification) + Connotation (2nd Order Signification) = Myth
Consider a front-page photo of a politician holding a baby. Denotation: a person, an infant. Connotation: warmth, trustworthiness, family values. When media constantly repeat such images, the connotation becomes a naturalised myth: ‘politicians care about families’. Analysing myth reveals hidden ideologies.
以一张政治家怀抱婴儿的头版照片为例。外延：一个人，一个婴儿。内涵：温暖、可信赖、家庭价值观。当媒体不断重复这类图像，内涵就变成一种自然化的神话：‘政客关爱家庭’。分析神话能够揭示隐藏的意识形态。
4. Todorov's Narrative Equilibrium Theorem | 托多罗夫的叙事平衡定理
Tzvetan Todorov proposed that most stories follow a five-stage structure moving from stability to transformation and back to a new stability. This theorem is incredibly useful for analysing the plot of films, TV dramas, adverts and even news stories.
茨维坦·托多罗夫提出，大多数故事遵循一个五阶段结构，从稳定走向变化，再回到一种新的稳定。这个定理对于分析电影、电视剧、广告甚至新闻故事的剧情极为有用。
Equilibrium → Disruption → Recognition of Disruption → Attempt to Repair → New Equilibrium
Equilibrium: The normal, balanced state at the start.
平衡：故事开始时正常、安定的状态。
Disruption: An event that breaks the equilibrium.
打破：打破平衡的事件。
Recognition: The characters realise the disruption has occurred.
认知：角色意识到破坏已经发生。
Attempt to Repair: Characters take action to restore order.
修复尝试：角色采取行动恢复秩序。
New Equilibrium: A transformed state, often not identical to the original.
新平衡：一个转变后的状态，通常与原初不同。
Apply this to a superhero film: the city is safe (equilibrium), a villain attacks (disruption), the hero learns of the threat, fights back, and peace returns but with changes in the character’s life or society. Todorov’s theorem helps you structure your response in exam essays.
把这个定理应用到一部超级英雄电影中：城市安全（平衡），反派袭击（打破），英雄得知威胁，反击，和平恢复（新平衡）但角色生活或社会发生了变化。托多罗夫的定理能帮你组织考试论文的回答结构。
5. Propp's Character Functions Formula | 普罗普的角色功能公式
Vladimir Propp studied Russian fairy tales and identified seven recurring character types, or ‘spheres of action’. While originally for folk tales, this formula can be adapted to modern media narratives, helping us map character roles in almost any genre.
弗拉基米尔·普罗普研究了俄罗斯民间故事，归纳出七种反复出现的角色类型或“行动范围”。虽然最初针对民间故事，但这个公式可以适用于现代媒体叙事，帮助我们梳理几乎任何类型中的角色功能。
es = Villain + Donor + Helper + Princess (and her father) + Dispatcher + Hero + False Hero
The Villain struggles against the hero.
坏人：与英雄斗争。
The Donor provides a magical object or wisdom.
捐献者：提供魔法物品或智慧。
The Helper aids the hero on the quest.
帮手：在征程中帮助英雄。
The Princess (and her Father) are the reward and often set the task.
公主（及其父王）：是奖赏，常常设定任务。
The Dispatcher sends the hero off.
派遣者：派遣英雄踏上旅途。
The Hero reacts to the donor and weds the princess.
英雄：回应捐献者，与公主成婚。
The False Hero appears heroic but is exposed as a fraud.
伪英雄：表面英雄，最终被揭穿。
Modern example: In Star Wars, Luke is the Hero, Obi-Wan is the Donor/Dispatcher, Han Solo is the Helper, Darth Vader is the Villain, Princess Leia is the Princess, and Darth Maul or Kylo Ren could serve as a False Hero figure. Propp’s formula reveals how classic patterns persist in contemporary media.
现代例子：在《星球大战》中，卢克是英雄，欧比旺是捐献者/派遣者，汉·索罗是帮手，达斯·维达是坏人，莱娅公主是公主，而达斯·摩尔或凯洛·伦可以充当伪英雄。普罗普的公式揭示了经典模式如何在当代媒体中延续。
6. Lévi-Strauss' Binary Opposition Theorem | 列维-斯特劳斯的二元对立定理
Claude Lévi-Strauss argued that meaning is produced through pairs of opposing concepts. By setting up contrasts such as good vs evil, civilisation vs wilderness, or masculine vs feminine, media texts create conflict, drive narrative, and reinforce cultural values. This theorem is crucial for analysing representation and ideology.
克劳德·列维-斯特劳斯认为，意义是通过成对的对立概念产生的。通过设立善与恶、文明与荒野、男性气质与女性气质等对立，媒体文本制造冲突、推动叙事并强化文化价值观。这个定理对于分析表征和意识形态至关重要。
Meaning = Binary Opposition (Concept A vs Concept B)
Common binary oppositions in media include: young/old, rich/poor, East/West, human/alien, natural/artificial, rational/emotional. In a horror film, the opposition between the ‘normal’ family and the monstrous ‘other’ creates tension. In a news report, portraying ‘hardworking taxpayers’ vs ‘welfare scroungers’ constructs a political message. Identifying these oppositions helps you deconstruct the text’s deeper meanings.
媒体中常见的二元对立包括：年轻/年老、富有/贫穷、东方/西方、人类/外星人、自然/人工、理性/情感。在恐怖片中，“正常”家庭与怪物“他者”之间的对立制造紧张感。在一则新闻报道中，塑造“勤劳的纳税人”与“福利蛀虫”的对立就构建了一种政治信息。识别这些对立能帮助你解构文本的深层意义。
7. Hall's Encoding/Decoding Model | 霍尔的编码与解码模型
Stuart Hall's model explains that meaning does not simply travel from producer to audience. Producers encode texts with a preferred meaning, but audiences decode them based on their own cultural background. This interaction determines whether the message is accepted, negotiated or rejected.
斯图亚特·霍尔的模型解释说，意义并非简单地从制作者传递给受众。制作者将文本编码为一种偏好意义，但受众依据自己的文化背景进行解码。这种互动决定了信息是被接受、协商还是拒绝。
Encoding (Producers' intended meaning) → Decoding (Audience interpretation in 3 possible positions)
Dominant/Preferred Reading: The audience fully accepts the intended message (e.g. agreeing with a charity advert’s call to action).
主控式/偏好阅读：受众完全接受预定信息（如同意公益广告的行动呼吁）。
Negotiated Reading: The audience broadly accepts the message but modifies it based on personal experience (e.g. seeing a product as desirable but too expensive for them).
协商式阅读：受众大体接受信息，但根据个人经验加以修改（如认为某产品令人向往但对自己来说太贵了）。
Oppositional Reading: The audience rejects the message and interprets it in a contrary way (e.g. viewing a ‘luxury lifestyle’ advert as promoting shallow values).
对立式阅读：受众拒绝信息，并以相反方式解读（如认为广告宣扬的“奢华生活”助长肤浅价值观）。
This formula is vital for audience-centred analysis. Always ask: how might different social groups (age, class, gender, ethnicity) read this text differently?
这个公式对于以受众为中心的分析至关重要。始终要问：不同的社会群体（年龄、阶级、性别、族裔）会如何以不同方式解读这个文本？
8. Uses and Gratifications Formula | 使用与满足公式
Blumler and Katz turned the question around: instead of asking ‘what do media do to audiences?’, they asked ‘what do audiences do with media?’. Audiences actively select media to satisfy specific needs. This formula helps explain why the same programme can be consumed for very different reasons.
布卢姆勒和卡茨把问题反转了过来：不问“媒体对受众做了什么”，而是问“受众用媒体做什么”。受众主动选择媒体来满足特定需求。这个公式有助于解释为什么同一节目会因为截然不同的原因被消费。
a Use = Information + Personal Identity + Integration & Social Interaction + Entertainment
Information: We use media to learn about the world, seek advice, or satisfy curiosity (e.g. watching news, tutorials).
信息：我们通过媒体了解世界、寻求建议或满足好奇心（如看新闻、教程）。
Personal Identity: We reinforce our own values, find models of behaviour, and identify with characters (e.g. following influencers who share our beliefs).
个人身份认同：我们强化自身价值观，寻找行为榜样，与角色产生认同（如关注与自己信念一致的网红）。
Integration and Social Interaction: Media provide a basis for social conversation and a sense of belonging to a community (e.g. discussing the latest episode with friends, participating in fandoms).
整合与社会互动：媒体为社交对话提供基础，带来社区归属感（如与朋友讨论最新剧集，参与粉丝圈）。
Entertainment: We use media for escapism, relaxation, and enjoyment (e.g. streaming films, playing games).
娱乐：我们通过媒体逃避现实、放松和享受乐趣（如看电影、玩游戏）。
In a WJEC exam question about audience, quantitatively invoke this formula by linking specific media elements to the need they gratify.
在 WJEC 有关受众的考题中，请熟练运用这个公式，将具体的媒体元素与其满足的需求联系起来。
9. Hesmondhalgh's Cultural Industries Theorem | 赫斯蒙德哈尔什的文化产业定理
David Hesmondhalgh describes how media industries operate under high risk and uncertainty. Because no one can guarantee a hit, companies use specific strategies to minimise risk and maximise profit. This theorem is essential for answering questions on industry, marketing, and production contexts.
戴维·赫斯蒙德哈尔什描述了媒体产业如何在高风险和不确定性下运作。因为没有人能确保作品一定成功，公司会运用特定策略来最小化风险并最大化利润。这个定理对于回答产业、营销和生产背景类问题至关重要。
Risk Minimisation = Formatting + Star Power + Genre Repetition + Conglomeration
Formatting: Using proven templates (talent shows, sequels, franchises) to increase predictability.
格式化：使用经过验证的模板（才艺秀、续集、系列电影）以提高可预测性。
Star Power: Featuring well-known actors, directors or personalities to attract pre-existing audiences.
明星效应：拥用著名演员、导演或名人来吸引现有受众。
Genre Repetition: Relying on familiar genre conventions that audiences already enjoy and recognise.
类型重复：依赖受众已经熟悉和喜爱的类型惯例。
Conglomeration: Horizontal and vertical integration allow large corporations to control production, distribution and exhibition, spreading risk across multiple sectors.
集团化：横向与纵向整合使大型公司能够控制制作、发行和放映，将风险分散至多个板块。
Yet Hesmondhalgh also notes that the cultural industries must also appear fresh to avoid boredom, leading to controlled innovation. Apply this theorem when analysing film franchises like the Marvel Cinematic Universe or record labels releasing similar pop acts.
不过赫斯蒙德哈尔什也指出，文化产业还必须显得新颖以避免乏味，从而引导出受控的创新。分析漫威电影宇宙或唱片公司推出相似流行偶像时，就可以运用这一定理。
10. Neale's Genre Repetition and Difference Theorem | 尼尔的类型重复与差异定理
Steve Neale argues that genres are not fixed boxes but dynamic systems that rely on both repetition and difference. Audiences expect certain conventions (so repetition is necessary for recognition), but they also crave novelty to stay engaged. This tension between familiarity and innovation drives genre evolution.
史蒂夫·尼尔认为，类型不是固定的盒子，而是依赖重复与差异的动态系统。受众期待某些惯例（因此重复对于可识别性必不可少），但同时也渴望新奇以维持兴趣。熟悉与创新之间的这种张力推动了类型的演变。
Genre = Repetition (Familiar Conventions) + Difference (Innovative Twists)
For example, a romantic comedy must include characteristic ‘meet-cute’ scenes and a happy resolution (repetition), but might subvert expectations with a same-sex relationship, an unusual setting or a non-linear narrative (difference). Media producers strategically manipulate this formula to attract both loyal genre fans and new audiences. In your essays, always identify what generic elements are repeated and where the text deviates, then suggest why—linking to industry and audience.
例如，一部浪漫喜剧必须包含典型的“巧遇邂逅”场景和美满结局（重复），但可能通过同性恋情、不寻常的场景或非线性叙事来颠覆预期（差异）。媒体制作者策略性地运用这个公式，以同时吸引忠实类型粉丝和新受众。在你的论文中，始终要指出哪些类型元素被重复，文本又在哪里有所偏离，然后推测原因——并与产业和受众联系起来。
