    Elements of Communication

    (According to Leagans’ Model):

    1. Communicator
    2. Message
    3. Channel
    4. Treatment
    5. Audience
    6. Audience Response

    1. Communicator
    • The initiator or sender of the message.
    • In Extension: a communicator may be a village-level worker, BDO, SMS, scientist, etc.
    • Source of knowledge: research institutes, universities, projects.
    • Extension agents carry messages from research to farmers.

    Credibility:

    • Means: Trustworthiness and competence.
    • Progressive villages: Scientist > Radio > Progressive Farmer > Extension Agency > Demonstration.
    • Non-progressive villages: Demonstration > Progressive Farmer > Scientist > Extension Agency > Radio.

    Attitude of Source: Should be favorable towards self, audience, and content.

    Fidelity: Refers to faithful performance of communication. Increases by skill, not just attitude.

     

    Key Communicator: A person sought for information and advice.

    • Identified using:
      1. Sociometric Method: Best method. Members nominate people they go to for advice. Result: Sociogram.
      2. Self-designating Method: Individuals assess themselves.
      3. Information-rating Method: Random members are asked to rate others’ influence.

     

    1. Message (Content)
    • What the communicator wants the audience to receive, understand, accept, and act upon.
    • Berlo’s Dimensions of Message:
      • Code: Symbols used (e.g., language, gestures).
      • Content: Information or subject.
      • Treatment: Manner or style of presentation.

    Characteristics of a Good Message: Timeliness, Specificity, Credibility

     

    Types of Message Distortion by (Kirk):

    1. Systematic Distortion: Message is changed but no information is lost.
    2. Fog Distortion: Maximum information loss occurs.
    3. Mirage Distortion: Unwanted/additional information gets mixed in.

     

    Encoding vs. Decoding:

    • Encoding: Sender’s act – Listening, Reading.
    • Decoding: Receiver’s act – Speaking, Writing.

     

    👉 Message Flow Models

    1. Hypodermic Needle Model: Assumes mass media has a direct, immediate, and powerful effect on a passive audience.
    2. Two-Step Flow Model (USA, 1940): Message flows from media → key communicator → audience.
    3. One-Step Flow Model: Message flows directly from media to audience, bypassing intermediaries. Acknowledges individual screening, personality effects.
    4. Multi-Step Flow Model: Message passes through multiple steps and layers, recognizing the complexity of influence in society.

     

    1. Channel; Channels are the physical or symbolic means through which a message travels from sender to receiver.
    • Definition: Channels are the physical bridges between the communicator and the audience.
    • Obstruction or Noise: Any disturbance that interferes with message transmission (e.g., unclear audio, illegible handwriting) is termed as noise.

     

    Types of Channels:

    Based on Form:

    1. Spoken Channels:
      • Examples: Farm and home visits, farmer’s call, meetings, radio talks.
      • Advantage: Allows immediate clarification and two-way interaction.
    2. Written Channels:
      • Examples: Personal letters, farm publications, newspapers, pamphlets.
      • Advantage: Provides permanent record and is useful for literate audiences.

     

    Based on Personal Involvement:

    1. Personal Localite:
      • Definition: Local leaders or individuals within the same social system of the receiver.
      • Example: Progressive farmers, village leaders.
      • Role: Highly credible and influential due to shared background.
    2. Personal Cosmopolite:
      • Definition: Communicators from outside the social system of the receiver, but with face-to-face contact.
      • Example: Extension agents, agricultural officers.
    3. Impersonal Cosmopolite:
      • Definition: Sources from outside the social system and with no personal interaction.
      • Example: Mass media (radio, TV, newspapers).
      • Role: Effective for large-scale dissemination, though less personalized.

     

    Based on Nature of Contact:

    1. Individual Contact:
      • Extension agent communicates one-on-one.
      • Examples: Farm and home visits, personal calls, consultations.
    2. Group Contact:
      • Extension agent communicates with a group, not individuals separately.
      • Examples: Group meetings, field days, training programs.
    3. Mass Contact:
      • Communication directed at a large audience simultaneously.
      • Examples: Campaigns, exhibitions, radio and TV programs, mass meetings.

     

    1. Treatment and Presentation
    • Treatment refers to the processing or tailoring of a message to make it:
      • Clear
      • Understandable
      • Realistic
    • Presentation is how the message is communicated or delivered to the audience.
      • It depends on:
        • Channel used
        • Nature of the audience (literate, illiterate, local, cosmopolitan, etc.)

    ✳️ Both treatment and presentation are vital to ensure effective understanding and impact.

     

    1. Audience
    • The audience (or receiver) is the target of the communication process.
    • They interpret, evaluate, and respond to the message.

    Audience Segmentation:

    • A communication strategy where the total audience is divided into sub-groups, and tailored messages are delivered to each group.
    • Example: Separating audience based on:
      • Age (youth, elderly)
      • Education level (illiterate, literate)
      • Occupation (farmers, agri-business owners)

    ✳️ This improves relevance and effectiveness of communication.

     

    1. Audience Response
    • It is the ultimate goal or final outcome of the communication process.
    • The receiver’s action or reaction (e.g., adopting a new practice, asking questions) is what completes the communication loop.
    • It is considered the terminating element in the communication cycle.

     

    1. Feedback
    • Feedback is essential to complete the communication process in extension education.
    • It is the reaction or response of the audience that is carried back to the communicator.
    • Example: A farmer applying a suggested practice and reporting results to the extension worker.

     

    Key Points:

    • “Action-Reaction” Interdependence is feedback.
    • It helps the communicator modify or reinforce the message.
    • Source-oriented: The communicator initiates and uses feedback to improve future communication.

    🔹 The concept of communication (including feedback) was explained by D. Berlo in his famous SMCR model:

    • S: Source (Communicator)
    • M: Message
    • C: Channel
    • R: Receiver (Audience)
