Introduction
Communication models are simple “maps” that show how messages move between people.
They help us understand why a message becomes clear in some situations and confusing in others.
In Unit 4, UGC NET often tests feedback, noise, context, and the difference between one-way and two-way communication.
In Real Life: We shift between speeches, chats, phone calls, and WhatsApp messages, and each situation matches a different model.
Exam Point of View: Most mistakes happen when students mix up interactive and transactional models, or ignore field of experience.
Why Communication Models are Needed
Communication is happening all the time, but it is not always easy to “see” the process. Models convert an invisible process into a visible structure. When you can see the structure, you can compare models, spot barriers, and answer exam questions quickly.
What a communication model explains
A communication model explains the path of meaning from one person to another. It usually answers these ideas in a structured way.
- Who starts communication
- What is being shared
- How it is sent
- Who receives it
- What response comes back
- What disturbs the message
- What result happens in the end
Common components of communication models
Most models use the same components, even if the names change slightly.
- Sender
The person or group who starts communication. - Message
The idea, information, emotion, or instruction that is shared. - Encoding
Encoding is an academic word meaning converting ideas into symbols. In simple English, it means turning thoughts into words, gestures, emojis, pictures, or signals. - Channel
The medium used to send the message, such as speech, phone, email, poster, WhatsApp, or TV. - Receiver
The person or group who gets the message. - Decoding
Decoding means converting symbols back into meaning. In simple English, it means understanding what the sender actually meant. - Feedback
The reply or response from the receiver, such as questions, reactions, facial expressions, or a written reply. - Noise
Noise means any disturbance that changes or reduces the clarity of the message.
- Physical noise includes sound, weak network, unclear mic, bad handwriting
- Semantic noise includes confusing words, jargon, double meaning terms
- Psychological noise includes stress, fear, anger, bias, lack of interest
- Cultural noise includes language gap, values gap, social norms mismatch
- Context
Context means the surrounding situation. In simple English, it includes place, time, relationship, culture, mood, and purpose.
Why misunderstandings happen
Misunderstanding happens when the receiver decodes the message differently from what the sender intended. This usually occurs because of noise, weak feedback, or different backgrounds.
Schramm used a very important idea called field of experience. Field of experience is an academic phrase meaning a person’s background. In simple English, it includes language, knowledge level, culture, and past learning.
When the sender and receiver do not share enough common experience, the same words can create different meanings.
Linear models of communication
Linear models show communication as a straight path. The message mostly moves in one direction, from sender to receiver. These models are common in speeches, announcements, and mass communication where the audience does not respond immediately.
Core idea and best use
Linear models work best when the purpose is to inform, instruct, or persuade a large audience quickly. They are less effective when doubts must be cleared immediately, because feedback is weak or missing.
Aristotle model
Aristotle’s model is one of the earliest models and it is mainly linked with public speaking.
Structure
- Speaker
- Speech
- Audience
Key focus
- The model focuses on persuasion and influence, especially how a speaker’s message impacts the audience.
Strengths
- Simple and easy for speech situations
- Useful for understanding public speaking and rhetoric, which means the art of persuasive speaking
Limitations
- Feedback is not emphasized
- Audience is mostly treated as passive
- Noise and context are not clearly shown
Situational Example: A teacher gives a motivational speech in assembly. Students listen silently, and the teacher measures success by audience reaction and discipline.
Lasswell model
Lasswell presented communication as a formula that helps analyze mass media communication.
Formula
Who → Says What → Which Channel → To Whom → With What Effect
What makes it special
- It highlights effect, meaning the result of communication on people, such as attitude change, belief change, or behavior change.
Strengths
- Very useful for media, advertising, political communication, propaganda, and public campaigns
- Helps analyze communication outcomes clearly
Limitations
- Feedback is not clearly shown
- Communication looks like a one-direction influence
- Real-life communication can be more interactive than this model suggests
Shannon–Weaver model
Shannon–Weaver is closely linked with telephone systems and information theory. It explains communication as a signal process and clearly highlights disturbance.
Basic flow
Source → Transmitter → Channel → Receiver → Destination
What makes it special
- It clearly shows noise affecting the channel, so it becomes an exam-friendly clue.
Strengths
- Excellent for technical and digital communication
- Helps understand signal distortion, message loss, and clarity issues
- Strongly connects communication with engineering-style thinking
Limitations
- Human emotions and relationships are not emphasized
- Communication is treated as message transfer, not meaning creation
- Feedback is not central in the original version
Linear models summary table
| Model | Main idea | Strong clue words | Best fit situations |
|---|---|---|---|
| Aristotle | Speaker influences audience | speaker, speech, audience | speech, lecture, assembly |
| Lasswell | Communication measured by effect | effect, mass media | advertising, campaigns, TV |
| Shannon–Weaver | Noise disturbs message in channel | transmitter, noise | phone, internet, signal |
Interactive models of communication
Interactive models include two-way communication. The sender sends a message, the receiver responds, and this response helps improve the next message.
Interactive models are better than linear models when clarification is needed.
Schramm interactive model
Schramm explained communication using feedback and field of experience.
Core ideas
- Communication becomes effective when sender and receiver share common experiences
- Feedback helps correct misunderstanding
- Misunderstanding increases when field of experience overlaps less
Field of experience is an academic phrase meaning the background of the sender and receiver. In simple English, it includes language, knowledge, culture, and past learning.
Strengths
- Explains misunderstanding in a realistic way
- Highlights the importance of shared knowledge
- Shows the value of feedback in improving clarity
Limitations
- Still often looks like turn-by-turn communication
- Simultaneous sending and receiving is not fully captured
Osgood–Schramm circular model
Osgood–Schramm presented communication as a continuous circular process. Both people act as sender and receiver.
Key idea
- Each person is continuously encoding, decoding, and interpreting
- Communication is not a straight line, it is a repeating cycle
Strengths
- Realistic for conversations and discussions
- Supports the idea that roles change quickly
- Shows communication as continuous, not one-time
Limitations
- Noise and context are not always shown as clearly as in transactional thinking
- Communication in large mass settings is not the main focus
Transactional model of communication
Transactional communication treats communication as simultaneous. People do not wait like turn-by-turn strictly. They send and receive together using words, tone, and body language.
Simultaneous is an academic word meaning happening at the same time. In simple English, it means both people communicate together.
Transactional communication
Core ideas
- Both participants are sender and receiver at the same time
- Meaning is created together, not simply transferred
- Non-verbal cues strongly shape meaning, such as facial expression, tone, posture, silence, and timing
Role of context and relationship
The same message can create different meanings depending on the situation.
- Relationship changes meaning, such as friend versus teacher versus parent
- Place changes meaning, such as classroom versus home versus office
- Mood changes meaning, such as calm versus angry
- Culture changes meaning, such as formal society versus casual society
Barnlund is commonly linked with transactional thinking because he focused on cues and meaning creation in real interactions.
Exam Point of View: Transactional model is the safest answer when a question mentions context, relationship, non-verbal cues, and meaning being created together.
Exam-friendly comparisons and common confusions
Linear vs interactive vs transactional
| Point | Linear | Interactive | Transactional |
|---|---|---|---|
| Direction | One-way | Two-way | Simultaneous two-way |
| Feedback | Weak or missing | Present | Continuous and natural |
| Receiver role | Mostly passive | Active responder | Co-creator of meaning |
| Context emphasis | Low | Medium | Very high |
| Best example | Speech, notice | Q and A, email replies | Face-to-face talk, phone call tone |
Where feedback appears
- Linear models usually do not show feedback clearly
- Interactive models show feedback as a major part
- Transactional model treats feedback as continuous through verbal and non-verbal signals
Where noise is highlighted
Noise can exist in all communication, but Shannon–Weaver highlights it clearly. If the question strongly points to disturbance in the channel, Shannon–Weaver is usually the best match.
Field of experience and misunderstanding
Field of experience is strongly linked with Schramm. It explains why the same message can be decoded differently by different people based on knowledge and background.
Other important communication models often asked
UGC NET sometimes asks models beyond the basic three types. Knowing these helps you handle difficult options in MCQs.
Berlo SMCR model
Berlo explained communication using four major components.
SMCR
- Source
- Message
- Channel
- Receiver
Berlo also explained that communication quality depends on communication skills, attitude, knowledge, social system, and culture of both source and receiver.
Dance helical model
Dance explained communication as a helix, which means a spiral.
Helix is an academic word meaning a spiral shape. In simple English, it means communication grows and changes as we gain experience. Each new conversation is influenced by previous conversations.
Key idea
- Communication is continuous and dynamic
- Past experiences shape future messages
Newcomb ABX model
Newcomb described communication as a balance in social relationships.
Core idea
- A and B communicate about X
- Communication helps maintain balance in relationships and shared understanding
This is useful for group communication and social interaction questions.
Westley and MacLean model
This model is often linked with mass communication.
Key idea
- Many events happen in the environment
- Media selects and shapes messages before they reach audiences
- Gatekeeping happens, which means selecting what information to pass
Gatekeeping is an academic word meaning controlling the flow of information. In simple English, it means deciding what news to show and what to hide.
Gerbner model
Gerbner explained communication as perception and representation.
Key idea
- People perceive events differently
- Messages are constructed and then interpreted
- Media representation can shape reality for audiences
Quick table of extra model clues
| Model | Best clue words | Common exam use |
|---|---|---|
| Berlo SMCR | source, message, channel, receiver | components and factors |
| Dance helical | spiral, growth, experience | continuous development |
| Newcomb ABX | balance, relationship, A B X | social interaction |
| Westley MacLean | mass media, gatekeeping | media selection |
| Gerbner | perception, representation | media reality shaping |
Key Points – Takeaways
- Communication models simplify a complex process into clear parts that are easy to study.
- Most models include sender, message, channel, receiver, and decoding.
- Encoding means converting ideas into symbols, and decoding means converting symbols into meaning.
- Noise reduces clarity and can be physical, semantic, psychological, or cultural.
Exam Point of View: If a question highlights disturbance inside the channel, transmitter, or signal distortion, Shannon–Weaver is usually the strongest option.
- Linear models are one-way and fit speeches, announcements, and mass messages.
- Aristotle focuses on speaker, speech, and audience, so it fits public speaking.
- Lasswell includes effect, so it fits media influence and persuasion analysis.
- Shannon–Weaver highlights noise, so it fits phone, internet, and technical messaging.
Exam Point of View: If a question includes the word effect or audience impact, Lasswell becomes a high-probability answer.
- Interactive models include feedback, so they fit discussion and clarification situations.
- Schramm explains misunderstanding using field of experience.
- Osgood–Schramm is circular and treats both as sender and receiver in conversation.
- Transactional model is simultaneous and depends heavily on context and relationship.
Exam Point of View: The common trap is to treat transactional as just two-way. Transactional is two-way plus simultaneous exchange plus context and non-verbal cues.
Model-wise structure and flow
This section gives you clean step patterns for quick recall. Use these when you want to match a scenario to a model.
Linear flow pattern
- Sender encodes a message
- Message travels through a channel
- Receiver decodes the message
- Effect happens in the receiver, such as understanding or behavior change
Linear flow fits situations where feedback is not expected immediately.
Shannon–Weaver flow pattern
- Source creates the message
- Transmitter converts message into signals
- Channel carries signals and noise may disturb them
- Receiver reconstructs the signal into a message
- Destination receives the final meaning
Interactive flow pattern
- Sender sends a message
- Receiver decodes and responds
- Feedback returns to sender
- Sender adjusts the next message based on feedback
- Shared field of experience increases clarity and reduces misunderstanding
Transactional flow pattern
- Both participants send and receive simultaneously
- Meaning is shaped by words, tone, and non-verbal cues
- Context and relationship continuously change interpretation
- Communication continues as a living process, not a fixed sequence
One-shot summary table
| Model type | What happens most | Best clue idea |
|---|---|---|
| Linear | Message moves one way | speech and announcement |
| Interactive | Feedback improves meaning | field of experience matters |
| Transactional | Meaning is created together | context and relationship dominate |
Examples
Example 1: A principal announces a rule in the assembly and students listen quietly without asking questions. This is a linear situation because the message moves one-way and the audience response is not used to shape the message.
Example 2: A teacher teaches a concept, then students ask doubts, and the teacher changes the explanation based on their questions. This matches interactive communication because feedback helps the sender improve clarity, and understanding becomes better after response.
Example 3: You tell your friend on a phone call to come at six, but network disturbance breaks your voice and your friend hears a different time. This matches Shannon–Weaver thinking because noise in the channel changes the message before it reaches the receiver.
Example 4: Two friends talk face-to-face, and one says “I am fine” but the tone sounds upset and the face looks tense, so the other friend understands that something is wrong. This matches transactional communication because meaning is shaped by tone, expression, relationship, and the situation.
Example 5: Ravi asked his classmate, “Are you joining the group study today.” The classmate replied “Yes,” but kept avoiding eye contact and continued scrolling on the phone. Ravi felt the response was not confident and he planned a backup partner. Later the classmate did not come, and Ravi understood that silence, attention, and body language also communicate meaning.
