1. Uses and Gratifications Theory | 使用与满足理论
Core Formula: Media Use = f (Individual Needs, Social Environment, Media Options). Audience members actively select and use media to satisfy specific gratifications.
核心公式：媒体使用 = f（个人需求、社会环境、媒体选择）。受众成员主动选择并使用媒体来满足特定的满足感。
Developed by Blumler and Katz, this theory shifts focus from ‘what media do to people’ to ‘what people do with media’. Audiences are not passive; they seek entertainment, information, personal identity and social interaction. A teenager scrolling TikTok for humour and a professional reading news for information both apply the same active choice mechanism.
此理论由布鲁默和卡茨提出，将焦点从“媒体对人们做了什么”转向“人们用媒体做了什么”。受众并非被动，他们寻求娱乐、信息、个人认同和社交互动。青少年浏览TikTok搞笑视频与专业人士阅读新闻获取信息，都运用了同样主动选择的机制。
2. Encoding/Decoding Model | 编码/解码模型
Stuart Hall’s Model: Meaning = Producer’s Encoding ↪ Text Encoding ↪ Audience Decoding. Misunderstanding occurs when codes are not shared.
斯图尔特·霍尔模型：意义 = 制作者编码 → 文本编码 → 受众解码。当编码与解码的符码不共享时会产生误读。
Hall argued that media messages are encoded with intended meanings, but audiences decode them through their own cultural frameworks. The same advertisement can be interpreted differently by diverse audiences based on class, gender or ethnicity. This reveals that meaning is not fixed but negotiated.
霍尔指出，媒体信息以预设意义进行编码，但受众会通过自身的文化框架解码。同一条广告可能被不同受众因阶级、性别或种族差异而解读各异。这表明意义并非固定，而是协商而成。
3. Agenda-Setting Theory | 议程设置理论
Theorem: The press may not be successful in telling people what to think, but it is stunningly successful in telling them what to think about. (Bernard Cohen, 1963)
定理：媒体或许不能成功告诉人们怎么想，却在极大程度上成功告诉人们该想什么。（伯纳德·科恩，1963年）
McCombs and Shaw demonstrated that the salience of issues in the news correlates with the public’s perception of importance. If climate change dominates headlines, audiences rank it as a top concern. This agenda-transfer informs the ‘framing’ effect, where media not only select issues but shape how they are understood.
麦库姆斯和肖证明，新闻议题的显著性与公众对重要性的认知高度相关。若气候变化占据头条，受众就会将其列为头等大事。这种议程转移促成了“框架”效应，即媒体不仅挑选议题，还塑造人们理解议题的方式。
4. Representation and Stereotypes | 表征与刻板印象
Representation Formula: Reality → Mediation (Selection, Omission, Construction) → Mediated Representation → Audience Perception. Stereotypes are simplified, exaggerated representations that reduce complexity.
表征公式：现实 → 中介化（选择、省略、构建） → 媒介化表征 → 受众认知。刻板印象是简化、夸大的表征，以消减复杂性。
Stuart Hall calls representation the process by which meaning is produced through language and signs. Stereotypes often reflect power imbalances, as in the portrayal of ethnic minorities or women. Laura Mulvey’s Male Gaze theory extends this by examining how visual media positions women as passive objects of a heterosexual male viewer.
斯图尔特·霍尔将表征称为通过语言和符号产生意义的过程。刻板印象常反映权力失衡，如对少数族裔或女性的刻画。劳拉·穆尔维的男性凝视理论进一步探讨视觉媒体如何将女性定位为异性恋男性观者的被动对象。
5. Semiotics: Signifier and Signified | 符号学：能指与所指
Saussure’s Principle: Sign = Signifier (form) + Signified (concept). Their relationship is arbitrary and governed by cultural codes.
索绪尔原理：符号 = 能指（形式） + 所指（概念）。二者之间的关系是任意的，由文化符码支配。
A red traffic light (signifier) signifies ‘stop’ (signified). In media texts, denotation is the literal meaning, while connotation is the associated meaning. Roland Barthes expanded this with myth: a connotation that becomes so widely accepted it appears natural, like a luxury watch connoting success.
红色交通灯（能指）意指“停止”（所指）。在媒体文本中，外延是字面意义，内涵是联想意义。罗兰·巴特用神话拓展：内涵被广泛接受而显得自然，如奢华手表内涵成功。
6. Narrative Theories: Todorov’s Equilibrium | 叙事理论：托多罗夫平衡模型
Narrative Formula: Equilibrium → Disruption → Recognition → Attempt to Repair → New Equilibrium. Stories move from stability through conflict to resolution.
叙事公式：平衡 → 打破 → 辨识 → 尝试修复 → 新平衡。故事由稳定经过冲突走向化解。
Tzvetan Todorov’s model is widely applied to film, news and advertising. A charity advert might show a child suffering (disruption), the charity’s intervention (attempt to repair) and a hopeful outcome (new equilibrium). Propp’s character functions—hero, villain, helper—can be mapped onto narratives but Todorov’s structure underpins temporal flow.
茨维坦·托多罗夫的模型广泛运用于电影、新闻和广告。一则慈善广告可能展现儿童受苦（打破）、慈善介入（尝试修复）与充满希望的结局（新平衡）。普罗普的角色功能——英雄、反派、帮手——可套用于叙事，但托多罗夫的结构奠定了时间流程。
7. Media Effects Models: Hypodermic Needle vs Two-Step Flow | 媒体效果模型：皮下注射模型与两级传播
Hypodermic Needle Model (1930s): Media Message → Direct, Uniform Effect on Passive Audience. This early model assumed the media injects ideas directly into the mind.
皮下注射模型（1930年代）：媒体信息 → 对被动受众产生直接、均匀的效果。这个早期模型假设媒体直接将观念注入头脑。
Two-Step Flow (Lazarsfeld): Media Message → Opinion Leaders → Their Followers. Influence is mediated by personal relationships.
两级传播（拉扎斯菲尔德）：媒体信息 → 意见领袖 → 他们的追随者。影响力通过人际关系中介。
The hypodermic model, although discredited, remains useful for analysing moral panics over violent video games. The two-step flow highlights that audiences are not atomised but embedded in social networks, prefiguring contemporary influencer marketing.
皮下注射模型虽已被否定，仍可用于分析因暴力电子游戏引发的道德恐慌。两级传播则可凸显受众并非原子化个体，而是嵌入社会网络，为当今网红营销埋下伏笔。
8. Cultivation Theory and Mean World Syndrome | 培养理论与丑恶世界综合征
Gerbner’s Formula: Heavy TV Viewing → Cultivates Perception of Reality Mirrored from TV Content → Fearful ‘Mean World’ Outlook.
格伯纳公式：重度电视观看 → 培养出与电视内容相符的现实感知 → 充满恐惧的“丑恶世界”观。
Cultivation theory argues that television cultivates a shared worldview over time. Heavy viewers are more likely to overestimate violence, distrust others and adopt the ‘mean world syndrome’. This is not a direct effect but a gradual, cumulative process of symbolic environment absorption.
培养理论认为，电视长期培养出共享的世界观。重度观众更易高估暴力、不信任他人，并染上“丑恶世界综合征”。这不是直接效果，而是一个逐渐累积的符号环境吸收过程。
9. Reception Theory: Preferred, Negotiated, Oppositional Readings | 接受理论：主导式、协商式、对抗式解读
Hall’s Reading Positions: Preferred Reading (accepts intended meaning) ↔ Negotiated Reading (accepts partly but adapts) ↔ Oppositional Reading (rejects intended meaning entirely).
霍尔的解读立场：主导式解读（接受预期意义） ↔ 协商式解读（部分接受但调整） ↔ 对抗式解读（完全拒绝预期意义）。
Building on encoding/decoding, reception theory maps how real audiences interpret texts. A political broadcast’s preferred reading might support the party; a negotiated reading might agree with some policies but question others; an oppositional reading could frame it as propaganda. This model empowers the audience as active meaning-makers.
基于编码/解码模型，接受理论勾勒出真实受众如何解读文本。一则政治广播的主导式解读可能是支持该政党；协商式解读可能赞成部分政策但质疑其他；对抗式解读可能视其为宣传工具。该模型赋予受众作为积极意义制造者的权力。
10. Genre Theory and Hybridity | 类型理论与杂糅
Genre Formula: Repetition of Recognisable Elements (Iconography, Narrative Patterns) + Variation (to maintain interest) = Genre Evolution. Hybridity mixes conventions from different genres.
类型公式：重复可辨识元素（图像志、叙事模式） + 变化（维持兴趣） = 类型演化。杂糅混合了不同类型的惯例。
Genre offers audiences a set of expectations and producers a blueprint. Steve Neale argues that genres are instances of ‘repetition and difference’. A romantic comedy reuses meet-cute conventions but varies characters. Hybrid genres like dramedy or sci-fi horror borrow elements to attract broader audiences. Contemporary media are increasingly characterised by genre fluidity.
类型为受众提供一套预期，为制作者提供蓝图。史蒂夫·尼尔认为，类型是“重复与差异”的体现。一部浪漫喜剧重复了偶遇邂逅的惯例，但在角色上变化。剧喜或科幻恐怖等杂糅类型借用元素以吸引更广泛的受众。当代媒体日益呈现类型流动性。
