Step 1: Understanding the Concept:
Communication models are graphic or structural representations that describe the key components, steps, and flow of information within the communication process.
Step 2: Detailed Explanation:
J. Paul Leagans (1961), a pioneer in agricultural extension, designed a highly influential communication model tailored specifically for agricultural development.
Leagans' model of communication consists of exactly 6 essential, closely linked elements that must work together for communication to succeed:
1. Communicator (Source): The person who starts the communication process (e.g., the extension agent).
2. Message: The information, practice, or technology being shared.
3. Channel: The medium used to transmit the message (e.g., radio, demonstration, or leaflet).
4. Treatment: The physical and psychological formatting of the message to make it clear and interesting to the audience.
5. Audience: The intended receivers of the message (e.g., the farmers).
6. Audience Response: The action taken by the audience after receiving the message (e.g., adopting, rejecting, or seeking more information).
If any of these 6 elements are weak or fail to function, the entire communication process breaks down, resulting in a failure to transfer technology.
Therefore, Leagans' model contains 6 elements.
Step 3: Final Answer:
Leagans' model of communication contains 6 elements, matching Option (A).
