Complete exam-focused revision notes on communication processes, models, verbal and non-verbal cues, culture, groups, classrooms, barriers and mass media.
संचार केवल message भेजना नहीं है; साझा अर्थ बनाना, समझ की जाँच करना और feedback से सुधार करना है।
Shared meaning under a particular context
Communication is a dynamic process in which participants create, transmit, receive and interpret messages through symbols and channels within a context, with the possibility of feedback and noise.
Message पहुँच जाना communication की सफलता नहीं; receiver ने intended meaning समझा या नहीं—यह feedback से पता चलता है।
Information is content or data. Communication includes the relational process of encoding, channel selection, interpretation and feedback.
Elements and the feedback loop
Noise can affect any stage; context surrounds the entire process.
Words and gestures are symbols. Their interpretation depends on language, experience, relationship, expectations and culture.
एक ही शब्द अलग context में अलग अर्थ दे सकता है।
What makes communication a living process?
Participants often send and receive simultaneously. While one speaks, the other communicates attention, confusion or resistance non-verbally.
A message can be clarified or apologized for, but its occurrence and effect cannot be fully erased.
Every message carries content and also signals something about status, closeness, trust or power.
In social presence, silence, delay, posture and absence may also be interpreted. This does not mean every behaviour was intentionally sent.
It considers receiver knowledge, language, culture, needs, motivation, accessibility and the communication goal.
Classify by participants, direction, formality and medium
| Axis | Types | Fast clue |
|---|---|---|
| Participants | Intrapersonal, interpersonal, group, public, mass | Who/how many? |
| Direction | Upward, downward, horizontal/lateral, diagonal | Where in hierarchy? |
| Formality | Formal, informal/grapevine | Official channel? |
| Code/medium | Oral, written, visual, non-verbal, digital | How represented? |
Models are maps: each highlights a different feature
| Model | Core form | High-yield identity |
|---|---|---|
| Aristotle | Speaker → Speech → Audience → Effect | Rhetorical/public persuasion; speaker-centred linear model |
| Lasswell | Who says What in Which Channel to Whom with What Effect? | Mass communication and effect analysis |
| Shannon-Weaver | Source → transmitter → channel (+noise) → receiver → destination | Mathematical/engineering linear model; noise |
| Berlo SMCR | Source–Message–Channel–Receiver | Communication skills, attitudes, knowledge, social system, culture |
| Osgood-Schramm | Circular encoding–decoding–interpreting | Feedback and role interchange |
| Newcomb ABX | A and B communicate about X | Balance/orientation in a social system |
| Westley-MacLean | Events → communicator/gatekeeper → audience | Mass media, environmental events and gatekeeping |
| Dance helical | Expanding spiral | Communication develops cumulatively over time |
Choose the channel that fits the task
Spoken language in conversation, lecture, meeting, interview, telephone or video conference.
Strengths: speed, warmth, immediate clarification.
Limits: memory distortion, weak record, speaker anxiety.
Letters, notices, reports, e-mails, messages, articles and policy documents.
Strengths: record, precision, complex detail, wide distribution.
Limits: delayed feedback, tone ambiguity, literacy demand.
Charts, graphs, diagrams, maps, photographs, symbols, slides and demonstrations.
Strengths: pattern visibility, recall and explanation of relationships.
Limit: a decorative visual without a clear message adds noise.
Richer media carry more cues and allow faster feedback. Face-to-face is rich; a formal written report is leaner but better for stable, detailed records.
The parallel channel: body, voice, space, time and objects
| Field | Studies | Example |
|---|---|---|
| Kinesics | Body movement, gesture, posture, facial expression | Nod, folded arms, smile |
| Oculesics | Eye behaviour | Gaze, eye contact |
| Proxemics | Use of interpersonal space | Distance, seating position |
| Haptics | Touch | Handshake; culturally regulated |
| Chronemics | Use and meaning of time | Punctuality, waiting, speaking time |
| Paralanguage / vocalics | How words sound | Pitch, pace, volume, pause, tone |
| Artifacts | Objects and appearance | Dress, status symbols, room design |
| Physical environment | Spatial setting | Lighting, temperature, furniture |
A single gesture is not a universal lie detector. Interpret clusters of cues, baseline behaviour, context, culture and the person’s possible disability or discomfort.
एक gesture देखकर personality या intention तय करना गलत है।
The popular “7–38–55 rule” is often overgeneralized. Mehrabian’s findings concerned communication of feelings/attitudes under inconsistent verbal and non-verbal cues—not all communication.
Communicate across different meaning systems
Culture influences preferred directness, silence, emotional display, politeness, personal space, time orientation, hierarchy and the interpretation of gestures.
Inter-cultural competence का अर्थ दूसरे culture को stereotype करना नहीं, बल्कि curiosity और respectful adaptation रखना है।
More meaning is embedded in relationship, setting, shared history and non-verbal cues; messages may be indirect.
More meaning is made explicit in words; clarity, directness and written detail may be preferred.
These are tendencies, not labels for every individual.
Ethnocentrism: judging another culture by one’s own as the superior norm.
Cultural sensitivity: seeking local meanings while retaining ethical judgment.
Networks, roles, norms and decision quality
| Network | Structure | Likely strength |
|---|---|---|
| Wheel | One central member connects others | Fast for simple tasks; high centralization |
| Chain | Sequential hierarchy | Orderly, but filtering/distortion risk |
| Y | Chain with a branch | Moderately centralized |
| Circle | Each connects to neighbours | More participation; slower coordination |
| All-channel | Everyone can communicate with everyone | High satisfaction/creativity for complex tasks |
Strong cohesion plus pressure for unanimity can suppress dissent and realistic appraisal.
Prevention: invite critique, assign a devil’s advocate, seek outside views, let leader speak later.
From teacher transmission to learner meaning-making
Teacher talk is not equal to student learning. Effective classroom communication makes learner thinking visible.
Classifies classroom verbal behaviour into 10 categories:
Indirect teacher talk में feelings स्वीकारना, praise, ideas use करना और questions शामिल हैं।
Combine social presence, clear instructions, predictable structure, asynchronous access, captions/transcripts, timely feedback and multiple participation modes.
The 7 Cs plus listening, empathy and feedback
Empathy: understand another person’s perspective and feeling while maintaining boundaries.
Sympathy: feel concern/pity for them.
Express needs, boundaries and disagreement clearly while respecting others.
Assertive ≠ aggressive. Aggression violates the other’s dignity; passivity suppresses one’s own legitimate needs.
Specific, timely, task-focused, actionable and dialogic.
Diagnose the point of failure before choosing the repair
| Barrier | How it disrupts meaning | Typical repair |
|---|---|---|
| Physical/environmental | Noise, distance, poor lighting, overcrowding | Change setting; reduce disturbance |
| Physiological | Fatigue, pain, hearing/visual difficulty | Accessibility, breaks, multiple modes |
| Semantic/language | Jargon, ambiguity, unfamiliar code | Plain language, define, translate, examples |
| Psychological/emotional | Anxiety, prejudice, defensiveness, low trust | Psychological safety, empathy, timing |
| Perceptual | Selective attention and interpretation | Paraphrase, evidence, perspective check |
| Cultural | Different norms and meanings | Ask, verify, adapt, avoid stereotypes |
| Organizational | Hierarchy, filtering, status gap, overload | Shorter channels, open feedback, clarity |
| Technological | Device/network failure, poor digital skill | Test tools, backup mode, support |
Repeating the same unclear message louder does not remove semantic noise.
Barrier जिस स्तर पर है, repair भी उसी स्तर पर होना चाहिए।
Large, mediated, institutional and technologically reproduced communication
Mass audience एक जैसी नहीं होती; वह अनेक सामाजिक, भाषायी और सांस्कृतिक समूहों से बनती है।
Print, audio, video, live interaction and user participation now meet on digital platforms. The old producer–audience boundary becomes more porous.
PROSUMERCROSS-MEDIAON-DEMANDHow media selects, frames, influences and is used
| Theory/concept | What it says | Memory hook |
|---|---|---|
| Gatekeeping | Actors/routines select what enters the public flow | Which message passes the gate? |
| Agenda-setting | Media salience influences what issues people think about | What to think about—not necessarily what to think |
| Framing | Presentation emphasizes particular problem definitions/causes | Which angle becomes visible? |
| Two-step flow | Media influence often moves through opinion leaders | Media → leader → others |
| Uses and gratifications | Audiences actively choose media for needs | What do people do with media? |
| Cultivation | Long-term heavy exposure can shape perceptions of social reality | Repeated media world → worldview |
| Spiral of silence | Fear of isolation may silence perceived minority opinion | Opinion climate controls voice |
| Knowledge-gap hypothesis | Information growth may benefit higher-resource groups faster | More information can widen gaps |
