Unit 6: Communication - Subjective Questions

Communication is the process through which two or more persons exchange ideas, information, feelings, facts, or experiences to achieve mutual understanding and bring about a desired response.

In extension education, communication is a purposeful process by which an extension worker shares useful knowledge and technologies with rural people and receives feedback from them.

Important features:

• It involves at least a sender and a receiver.
• A meaningful message must be transmitted.
• It uses a suitable channel or medium.
• It aims at common understanding, not merely transmission.
• Feedback makes communication complete.
• It is a continuous, dynamic, and two-way process.
• In extension work, it seeks desirable changes in the farmers' knowledge, attitude, skills, and practices.

The major principles of effective communication are:

1. Clarity: The purpose and message should be clear, simple, and unambiguous.
2. Credibility: The communicator and the information communicated must be trustworthy.
3. Content relevance: The message should address the needs, interests, and problems of the audience.
4. Audience orientation: Communication must consider the receivers' education, culture, experience, and economic condition.
5. Appropriate channel: The medium should suit the message, audience, resources, and local situation.
6. Consistency: Messages from different sources should not contradict one another.
7. Completeness: All essential information required for understanding and action should be provided.
8. Timeliness: Information should reach people when it is most useful, such as before the sowing season.
9. Participation: The audience should be encouraged to ask questions, discuss, and share experiences.
10. Feedback: The communicator should verify whether the message has been understood and accepted.
11. Repetition and reinforcement: Important ideas may be repeated through different channels.
12. Learning by doing: Demonstrations and practical experiences improve understanding and retention.

Thus, communication becomes effective when it is need-based, understandable, credible, participatory, and action-oriented.

Communication performs the following functions in agricultural extension:

• Information function: It informs farmers about new technologies, government schemes, weather, markets, and input availability.
• Educational function: It develops knowledge and practical skills through training, demonstrations, and discussions.
• Persuasive function: It motivates farmers to examine and adopt beneficial innovations.
• Decision-support function: It helps farmers compare alternatives and make informed farm decisions.
• Coordination function: It connects farmers, scientists, extension agencies, markets, and local institutions.
• Socialization function: It transmits social values, norms, and community experiences.
• Problem-solving function: It enables farmers to express difficulties and obtain technical guidance.
• Feedback function: It carries farmers' reactions and field-level problems back to researchers and administrators.
• Motivational function: It builds confidence and encourages collective action and self-reliance.

Communication therefore links research, extension, and farmers and supports planned agricultural and rural development.

The communication process consists of the following elements:

1. Communicator or source: The person or institution that initiates communication, such as an extension officer.
2. Message: The information, idea, or recommendation being communicated.
3. Encoding: Converting an idea into words, pictures, signs, or demonstrations.
4. Channel: The means used to carry the message, such as a farm visit, radio programme, video, or leaflet.
5. Receiver: The person or group for whom the message is intended.
6. Decoding: Interpreting and assigning meaning to the received message.
7. Response: The receiver's reaction to the message.
8. Feedback: Information returned to the communicator about understanding or action.
9. Noise: Any physical, semantic, psychological, or technical disturbance affecting communication.
10. Context: The social, cultural, and physical situation in which communication occurs.

Example: An extension officer demonstrates seed treatment to farmers. The officer is the source, the treatment procedure is the message, the demonstration is the channel, and the farmers are the receivers. Farmers' questions and their ability to repeat the procedure provide feedback.

Aristotle's model is one of the earliest linear models of communication. It mainly explains public speaking and persuasion.

Basic sequence:

Speaker → Speech → Audience → Effect

It may also consider the occasion on which communication takes place.

Components:

• Speaker: The person delivering the message.
• Speech: The content and manner of presentation.
• Audience: The persons receiving the speech.
• Effect: The change in understanding, attitude, or behaviour produced by the speech.

Relevance to extension:

• Useful for farmer meetings, campaigns, lectures, and public addresses.
• Emphasizes the communicator's credibility and persuasive ability.
• Encourages adaptation of the message to the audience.

Limitations:

• It is mainly one-way and linear.
• It does not adequately include feedback.
• It gives little attention to noise and channel selection.
• It treats the audience largely as passive receivers.

Therefore, it is useful for analysing persuasive speeches but is insufficient for participatory extension communication.

Lasswell's model is expressed through the question:

Who says what, in which channel, to whom, and with what effect?

Its elements are communicator, message, medium, audience, and effect. It is useful for analysing mass communication, propaganda, and the outcome of a message.

Shannon–Weaver model contains:

Information source → Transmitter → Signal/Channel → Receiver → Destination

It also introduces noise, which can interfere with the signal during transmission.

Comparison:

• Purpose: Lasswell emphasizes persuasion and communication effects, whereas Shannon–Weaver emphasizes accurate technical transmission.
• Channel: Both models recognize the importance of a communication channel.
• Noise: Noise is an explicit component of the Shannon–Weaver model but not of Lasswell's original formulation.
• Effect: Lasswell directly asks about the effect of communication; Shannon–Weaver primarily examines signal accuracy.
• Feedback: Neither original model gives sufficient attention to feedback, although feedback was added in later adaptations.
• Nature: Both are primarily linear models.
• Application: Lasswell is useful for analysing agricultural campaigns and media messages, while Shannon–Weaver helps identify technical, environmental, and semantic disturbances.

Both models are valuable, but participatory extension requires a two-way model incorporating feedback and shared understanding.

Berlo's model explains communication through four major components: Source, Message, Channel, and Receiver, abbreviated as SMCR.

1. Source

The effectiveness of the source depends upon:

• Communication skills
• Attitudes
• Knowledge
• Social system
• Culture

2. Message

A message has:

• Content: The subject matter
• Elements: Verbal and non-verbal components
• Treatment: The way the content is organized and presented
• Structure: Arrangement of ideas
• Code: Language, symbols, pictures, or gestures used

3. Channel

Berlo relates channels to the human senses:

• Seeing
• Hearing
• Touching
• Smelling
• Tasting

4. Receiver

The receiver is influenced by the same factors as the source: communication skills, attitudes, knowledge, social system, and culture.

Extension relevance: An extension worker should possess technical knowledge and communication skills, encode recommendations in locally understandable forms, use suitable sensory channels, and consider the farmers' social and cultural backgrounds.

A major limitation is that the model does not explicitly show feedback or noise.

Linear model

• Communication moves in one direction from sender to receiver.
• The receiver is treated mainly as passive.
• Feedback is absent or ignored.
• Examples include Aristotle's model and the original Shannon–Weaver model.
• It is useful for announcements and mass-media broadcasts.

Interactional model

• Communication occurs in two directions.
• The receiver provides feedback after receiving the message.
• Sender and receiver exchange roles in turn.
• It recognizes context and the receiver's response.
• Examples include interviews, question-answer sessions, and advisory visits.

Transactional model

• Participants simultaneously send, receive, and interpret messages.
• Meaning is jointly created through continuous interaction.
• Verbal, non-verbal, cultural, social, and situational factors are recognized.
• Both participants are active communicators rather than fixed senders and receivers.

Most suitable model: The transactional model is generally the most suitable for extension education because extension is participatory and problem-oriented. It allows farmers to share indigenous knowledge, clarify doubts, give feedback, and participate in decisions. However, linear communication may still be useful for rapidly transmitting general information through radio, television, or mobile alerts.

Communication barriers may be classified as follows:

1. Physical barriers

Noise, distance, poor lighting, unsuitable seating, and interruptions may prevent proper reception.

2. Mechanical or technical barriers

Defective microphones, weak radio signals, poor internet connectivity, and printing errors interfere with transmission.

3. Semantic barriers

Difficult terminology, ambiguous words, unfamiliar symbols, translation errors, and excessive technical language create misunderstanding.

4. Psychological barriers

Prejudice, fear, anxiety, low motivation, distrust, and resistance to change affect attention and interpretation.

5. Socio-cultural barriers

Differences in language, caste, customs, beliefs, gender roles, values, and social status may reduce interaction.

6. Organizational barriers

Rigid hierarchy, delayed information, unclear responsibilities, information overload, and inadequate coordination hinder communication.

7. Personal barriers

Poor listening, lack of communication skills, limited knowledge, and negative attitudes of either the sender or receiver create difficulties.

8. Message-related barriers

An irrelevant, lengthy, untimely, incomplete, or poorly organized message may fail to produce understanding.

9. Channel-related barriers

Selecting a medium inaccessible or unsuitable to the audience reduces effectiveness.

These barriers may cause distortion, delay, misunderstanding, or complete failure of communication.

Communication barriers in rural extension can be reduced through the following measures:

• Conduct an audience analysis before planning the communication programme.
• Use simple, familiar, and locally understood language.
• Avoid unnecessary scientific terms; explain essential terms with examples.
• Select channels accessible to the audience and combine interpersonal and mass-media methods.
• Use pictures, specimens, models, demonstrations, and audiovisual aids.
• Encourage questions, discussion, and immediate feedback.
• Listen carefully to farmers and respect their experiences and indigenous knowledge.
• Present relevant information at the proper season and time.
• Test equipment and teaching materials before the programme.
• Build credibility through accurate information, honesty, and consistent field contact.
• Be sensitive to cultural beliefs, gender relations, literacy levels, and social differences.
• Summarize key ideas, repeat important points, and verify understanding through practical performance.

The central remedy is to make communication clear, participatory, locally relevant, and feedback-oriented.

Agricultural journalism is the collection, preparation, editing, publication, and dissemination of information related to agriculture and rural development through print, electronic, and digital media.

Scope:

• Crop and livestock production
• Horticulture, fisheries, and forestry
• Farm machinery and input use
• Agricultural research and innovations
• Weather and climate advisories
• Agricultural markets and prices
• Government policies, credit, and insurance
• Rural development and farmers' organizations
• Success stories and indigenous practices

Functions:

• Provides timely and reliable farm information.
• Educates farmers about improved practices.
• creates awareness of programmes, markets, and services.
• Connects scientists, extension personnel, policymakers, and farmers.
• Highlights farmers' problems and carries rural voices to decision-makers.
• Motivates adoption by presenting evidence and success stories.
• Preserves and shares useful local knowledge.
• Supports public discussion of agricultural and environmental issues.

Thus, agricultural journalism acts as an important bridge between knowledge-generating institutions and rural communities.

Effective agricultural writing should follow these principles:

• Accuracy: Facts, figures, names, recommendations, and scientific claims must be verified.
• Clarity: Short sentences and familiar words should be used.
• Relevance: The content must address farmers' actual needs and seasonal concerns.
• Timeliness: News should reach farmers when they can use it.
• Objectivity: Facts should be separated from opinion, promotion, or personal bias.
• Brevity: Unnecessary details should be removed without sacrificing essential information.
• Local orientation: Local examples, crops, prices, and conditions increase usefulness.
• Attribution: Information should be linked to credible experts or institutions.
• Human interest: Experiences and quotations from farmers make a feature engaging.
• Actionability: Recommendations should explain what to do, how to do it, and what precautions to take.

An agricultural news report commonly answers who, what, when, where, why, and how. News often uses the inverted-pyramid structure, placing the most important facts first. A feature article may use a more descriptive structure but must remain factually correct.

Agricultural journalism uses several media forms:

Print media

Newspapers, farm magazines, newsletters, leaflets, folders, bulletins, and posters provide permanent information that can be reread. However, their usefulness may be limited by literacy and delayed distribution.

Radio

Radio can reach large and scattered rural audiences at low cost and in local languages. It is useful for weather, market, and seasonal advisories, but messages are temporary unless repeated.

Television and video

These media combine sound and visuals and are suitable for showing farm operations. Their limitations include cost, electricity requirements, and limited opportunities for direct feedback.

Digital and social media

Websites, mobile applications, podcasts, messaging groups, and social platforms offer rapid, interactive, and multimedia communication. Challenges include digital literacy, connectivity, misinformation, and unequal access.

Community media

Community radio, local newsletters, folk media, and village information boards reflect local needs and encourage participation.

Interpersonal support

Journalistic messages become more effective when supported by extension workers, progressive farmers, and local leaders who clarify and demonstrate recommendations.

No single medium is universally best. A media mix selected according to audience, purpose, urgency, cost, and local accessibility produces better results.

An innovation is an idea, practice, or object perceived as new by an individual or another unit of adoption. The innovation need not be newly invented; it is sufficient that the potential adopter considers it new.

Diffusion is the process by which an innovation is communicated through certain channels over time among members of a social system.

The four main elements are:

1. Innovation: The new idea, technology, or practice being considered, such as a drought-tolerant crop variety.
2. Communication channels: The means through which information passes, including mass media, extension workers, neighbours, and digital platforms.
3. Time: It includes the duration of the decision process, the relative speed of adoption, and the rate at which the innovation spreads.
4. Social system: The community or network within which diffusion occurs. Its norms, leadership, institutions, and interpersonal relationships influence adoption.

Diffusion is therefore not merely the distribution of information; it is a social communication process involving learning, evaluation, influence, and decision-making.

Adoption is an individual-level process through which a person considers an innovation and decides to use it fully and continuously. Diffusion is the broader social process through which the innovation spreads among members of a social system.

Major differences:

• Unit of analysis: Adoption focuses on an individual, household, or organization; diffusion focuses on a social system or population.
• Main concern: Adoption examines personal decision-making; diffusion examines the spread and rate of acceptance.
• Outcome: Adoption results in acceptance, rejection, continuation, or discontinuance; diffusion results in a pattern of spread over time.
• Influences: Adoption is shaped by needs, resources, attitudes, and perceived attributes; diffusion is also shaped by networks, opinion leaders, communication channels, and social norms.
• Measurement: Adoption may be measured by whether and how intensively a person uses an innovation. Diffusion may be measured by the percentage of members adopting over time.

For example, one farmer's decision to use drip irrigation is adoption, while the gradual spread of drip irrigation throughout a district is diffusion.

The rate of adoption is strongly influenced by five perceived attributes:

1. Relative advantage: The degree to which an innovation is considered better than the existing practice. Higher profit, lower cost, reduced risk, or labour saving generally accelerates adoption.

2. Compatibility: The extent to which the innovation agrees with existing values, experience, farming systems, and needs. A compatible practice is more easily accepted.

3. Complexity: The perceived difficulty of understanding and using the innovation. Greater complexity generally slows adoption.

4. Trialability: The degree to which the innovation can be tested on a limited scale. Small-scale trials reduce uncertainty and encourage adoption.

5. Observability: The extent to which the results are visible to others. Clearly observable benefits encourage discussion and imitation.

Other factors include initial cost, risk, availability of inputs, reversibility, profitability, institutional support, and access to credit.

Extension agencies can increase adoption by demonstrating relative advantage, linking the innovation with local practices, simplifying instructions, permitting small trials, and making results observable through demonstrations and farmer field visits.

The traditional adoption process consists of five stages:

1. Awareness: The farmer first learns that an innovation exists but has limited information about it.
2. Interest: The farmer becomes interested and actively seeks additional information.
3. Evaluation: The farmer mentally assesses whether the innovation is suitable, profitable, and feasible under local conditions.
4. Trial: The farmer tests the innovation on a small scale to reduce uncertainty.
5. Adoption: After satisfactory results, the farmer decides to use the innovation fully and continuously.

Example of a new crop variety:

• A farmer hears about the variety through radio at the awareness stage.
• The farmer asks an extension worker for details at the interest stage.
• Yield, maturity period, cost, and market demand are considered at the evaluation stage.
• The variety is planted on a small plot at the trial stage.
• If the performance is satisfactory, it is planted on a larger area in subsequent seasons at the adoption stage.

The process is not always strictly linear. A farmer may skip stages, return to an earlier stage, reject the innovation, or discontinue it after adoption.

The innovation-decision process explains how an individual moves from first knowledge of an innovation to confirmation of a decision. It has five stages:

1. Knowledge: The person becomes aware of the innovation and learns how it functions.
2. Persuasion: A favourable or unfavourable attitude develops through information, observation, and discussion.
3. Decision: The person undertakes activities leading to adoption or rejection, often including a trial.
4. Implementation: The innovation is actually put into use. Reinvention or modification may occur at this stage.
5. Confirmation: The person seeks support for the decision and evaluates the results over time.

Possible outcomes:

• Continued adoption: Regular use is maintained.
• Rejection: The innovation is not adopted after consideration.
• Later adoption: Initial rejection is followed by adoption when conditions change.
• Discontinuance: Use stops after adoption.
• Replacement discontinuance: A better innovation replaces the earlier one.
• Disenchantment discontinuance: Use stops because results are unsatisfactory.

Extension support should therefore continue beyond the initial decision so that farmers can solve implementation problems and avoid unnecessary discontinuance.

Adopters are classified according to innovativeness, meaning the relative time at which they adopt an innovation compared with other members of a social system. The adoption-time distribution is commonly divided using the mean and standard deviation into five categories:

1. Innovators — : The first persons to adopt. They are venturesome and willing to take risks.
2. Early adopters — : Respected local opinion leaders who adopt after careful consideration.
3. Early majority — : Deliberate adopters who accept an innovation before the average member but require evidence.
4. Late majority — : Skeptical adopters who accept after the average member, often because of peer pressure or economic necessity.
5. Laggards — : The last to adopt; they tend to rely on tradition and require strong evidence and support.

The first two groups account for , while the two majority groups together account for .

This classification is relative to a particular innovation and social system. A farmer may be an innovator for one practice but a late adopter for another. The terms should therefore not be used as permanent or insulting labels.

Innovators

Characteristics: Venturesome, willing to take risks, technically curious, better connected with outside sources, and able to absorb possible losses.

Strategy: Provide early access to technical information, research contacts, prototypes, and opportunities for experimentation.

Early adopters

Characteristics: Respected community members, careful decision-makers, progressive, and influential as opinion leaders.

Strategy: Involve them in on-farm trials, demonstrations, field days, and farmer-to-farmer communication.

Early majority

Characteristics: Deliberate, practical, and willing to adopt after observing proven local results.

Strategy: Present reliable cost-benefit evidence, local success stories, training, and visible demonstrations.

Late majority

Characteristics: Skeptical, economically cautious, influenced by peer pressure, and likely to adopt only after an innovation becomes common.

Strategy: Reduce risk through subsidies, credit, input availability, group approaches, repeated guidance, and community endorsement.

Laggards

Characteristics: Tradition-oriented, locally focused, resource-constrained, and cautious because a failed decision may be highly damaging.

Strategy: Use patient interpersonal contact, simple recommendations, trusted local communicators, low-cost trials, and strong follow-up support.

Extension workers should avoid stereotyping. Strategies must also consider farmers' resources, needs, gender, access to information, and local conditions.
