Lesson 3

• Communication models


  Conceptual models that help understand how the communication process works
• Communication models covered


  • Aristotle's communication model
  • Laswell's communication model
  • Shannon and Weaver's communication model
  • Berlo's communication model
• Aristotle's communication model


  • 3 variables: Speaker, Speech, Audience
  • Linear process from speaker to audience
• Laswell's communication model


  • 5 variables: Communicator, Message, Medium, Receiver, Effect
  • Focuses on who says what through which channel to whom with what effect
• Shannon and Weaver's communication model

  • 7 variables: Source, Encoder, Channel, Noise, Decoder, Receiver, Feedback
  • Identifies noise as a factor affecting communication
• Berlo's communication model (SMCR)

  • 4 variables: Source, Message, Channel, Receiver
  • Source features: Communication skills, Attitude, Knowledge, Social system, Culture
  • Message features: Content, Elements, Treatment, Structure, Code
  • Channel is the medium used
  • Receiver features similar to Source
• Communication models help understand the communication process and the variables involved
