The main models of communication are usually grouped into three big types, and then explained through several classic specific models.

Big categories of communication models

  1. Linear models (one‑way)
    • Message moves in a straight line: sender → message → channel → receiver.
 * No real feedback; the receiver is mostly passive.

 * Common examples: advertisements, announcements, lectures, political speeches.
  1. Interactive models (two‑way with feedback)
    • Sender and receiver take turns: one sends, the other responds, with feedback loops.
 * Recognize that people interpret messages based on their background and experience.

 * Typical in emails, text messages, or Q&A sessions where you respond after the other person finishes.
  1. Transactional models (simultaneous, dynamic)
    • Both people are senders and receivers at the same time.
 * Emphasize context, culture, relationship, and noise (anything that disrupts the message).

 * Best fits real‑life conversations, meetings, and relationship‑based communication.

Key named models you’re likely to be asked about

1. Aristotle’s model (classic linear)

  • Focus: public speaking and persuasion.
  • Elements: speaker → speech → audience → effect (persuasion).
  • Works best for: speeches, debates, political rallies, formal presentations.

2. Shannon–Weaver model

  • Category: linear.
  • Elements: information source → transmitter (encoder) → channel → receiver (decoder) → destination.
  • Introduces noise : anything that interferes with the message (static on a call, bad handwriting, typos).
  • Originally for telephone/engineering communication, now used widely to explain basic transmission.

3. Lasswell’s model

  • Category: linear.
  • Famous formula: “Who says What in Which channel to Whom with What effect?”
  • Very useful for analyzing media messages, ads, PR campaigns, and political communication.

4. Berlo’s S‑M‑C‑R model

  • Category: linear (but more detailed).
  • S‑M‑C‑R stands for Source, Message, Channel, Receiver.
  • Adds depth: looks at factors like communication skills, attitudes, knowledge, social system, and culture for both source and receiver.
  • Highlights that how you say something (tone, nonverbal cues) is as important as what you say.

Interactive models

5. Osgood–Schramm model

  • Category: interactive.
  • Removes clear “sender/receiver” roles; both parties encode, decode, and interpret messages in turn.
  • Shows communication as a continuous circular process rather than a straight line.
  • Great for explaining conversations where meaning is negotiated back and forth.

6. Westley and MacLean model

  • Category: interactive.
  • Adds: multiple sources, environmental events, and gatekeepers (people who filter messages, like editors).
  • Useful for mass communication, news media, and social media flows where messages are selected and reshaped before you see them.

Transactional models

7. Barnlund’s transactional model

  • Category: transactional.
  • Emphasizes:
    • Simultaneous sending and receiving.
    • Multiple channels (verbal, nonverbal, written) at once.
    • Influence of personal experience, relationships, and social norms.
  • Good for understanding complex, real‑time interactions like team discussions or negotiations.

8. Dance’s helical model

  • Category: transactional.
  • Uses a helix (spiral) to show that communication:
    • Is continuous and never exactly repeats.
    • Expands and changes as we gain experience.
  • Helpful for seeing how long‑term relationships and communication patterns evolve over time.

Model Type Main idea Best for explaining
Aristotle Linear Speaker focuses on persuading an audience. Speeches, debates, rhetoric.
Shannon–Weaver Linear Technical transmission with noise affecting the signal. Phone calls, basic message transmission, noise effects.
Lasswell Linear “Who says what, in which channel, to whom, with what effect?” Media analysis, propaganda, campaigns.
Berlo S‑M‑C‑R Linear (detailed) Source, Message, Channel, Receiver, with focus on skills, attitudes, etc. Interpersonal and mass communication design.
Osgood–Schramm Interactive Circular, both sides encode and decode. Two‑way conversations, negotiated meaning.
Westley & MacLean Interactive Multiple sources, gatekeepers, feedback. News media, social media, public communication.
Barnlund Transactional Simultaneous sending/receiving, context and relationships. Real‑time interaction, group discussions.
Dance’s Helical Transactional Communication grows and changes like a spiral over time. Long‑term communication development.

How to remember “what are the different models of communication”

If you need a quick exam‑style answer to “what are the different models of communication?”, you can safely write:

  • There are three main types:
    • Linear models (Aristotle, Shannon–Weaver, Lasswell, Berlo S‑M‑C‑R).
* Interactive models (Osgood–Schramm, Westley and MacLean).

* Transactional models (Barnlund, Dance’s Helical).

In simple terms: linear is one‑way, interactive is two‑way with turn‑taking and feedback, and transactional is two‑way happening at the same time, shaped by context and relationships.
