Organizational Communication and Perception account for 3 to 5 questions in RBI Grade B Phase-2 and SEBI/PFRDA Grade A Paper-2. Every aspirant must memorize: (1) Classic Models of Communication (Aristotle’s Rhetoric, Harold Lasswell’s 5W Formula 1948, Shannon & Weaver’s Linear Mathematical Model 1949 [which introduced ‘Noise’ but originally lacked ‘Feedback’, later added by Norbert Wiener], Wilbur Schramm’s Interactive ‘Field of Experience’ Model 1954, David Berlo’s SMCR Model 1960, and Barnlund’s Transactional Model 1970); (2) Formal Small-Group Networks (Bavelas & Leavitt: Wheel, Y, Chain, Circle & All-Channel/Star); (3) Keith Davis’s 4 Informal Grapevine Chains (Single Strand, Gossip, Probability & Cluster — most common!); (4) Joseph Luft & Harrington Ingham’s Johari Window (1955 — Open/Arena, Blind Spot, Hidden/Facade, Unknown); and (5) Perceptual Shortcuts & Harold Kelley’s Attribution Theory (Distinctiveness, Consensus, Consistency).
1. Classic Models of Communication: Shannon–Weaver, Berlo’s SMCR, Schramm & Barnlund
In RBI Grade B and SEBI Grade A Paper-2, questions frequently test which communication model introduced a specific element (like Noise, Field of Experience, or SMCR):
| Communication Model & Year | Category | Exact Components, Innovations & Exam Triggers |
|---|---|---|
| 1. Aristotle’s Model (300 BC) | Linear (Public Speaking) | 5 Elements: Speaker → Speech → Occasion → Audience → Effect. Built on 3 persuasive pillars: Ethos (credibility/character), Pathos (emotional appeal), and Logos (logical reasoning). |
| 2. Harold Lasswell’s Model (1948) | Linear (Mass Media) | 5W Verbal Formula: Who (Sender) → Says What (Message) → In Which Channel (Medium) → To Whom (Receiver) → With What Effect? |
| 3. Shannon and Weaver’s Mathematical Model (1949) Claude Shannon & Warren Weaver (Bell Labs) |
Linear / Transmission Model ‘Mother of All Models’ |
• 6 Original Components: Information Source (Sender) → Transmitter (Encoder) → Signal/Channel (+ NOISE Source) → Receiver (Decoder) → Destination. • Exam Traps: 1. FIRST model to introduce the concept of ‘NOISE’ (technical, semantic, and effectiveness problems). 2. The original 1949 Shannon–Weaver model was strictly one-way (Linear) and did NOT include ‘Feedback’! Cybernetician Norbert Wiener later added the Feedback Loop to it. |
| 4. David Berlo’s SMCR Model (1960) | Linear Psychological Model | Expands Shannon–Weaver into 4 Core Components (S–M–C–R), each with 5 attributes: • S — Source (Sender): Communication Skills, Attitudes, Knowledge, Social System, Culture. • M — Message: Content, Elements, Treatment, Structure, Code. • C — Channel (5 Senses!): Hearing, Seeing, Touching, Smelling, Tasting. • R — Receiver: Same 5 attributes as Source (Communication Skills, Attitudes, Knowledge, Social System, Culture). |
| 5. Wilbur Schramm’s Osgood–Schramm Model (1954) | Interactive (Circular) Model | • Replaced one-way linear transmission with a two-way circular loop where each participant continuously acts as Encoder, Interpreter, and Decoder. • Coined the concept of ‘Field of Experience’ (effective communication occurs only in the overlapping area of shared background/culture/language between Sender and Receiver) and Semantic Noise. |
| 6. Dean Barnlund’s Transactional Model (1970) & Frank Dance’s Helical Model (1967) | Transactional / Dynamic Models | • Barnlund (1970): Sender and Receiver send and receive messages SIMULTANEOUSLY (concurrent verbal and non-verbal feedback) using Public Cues, Private Cues, and Behavioural Cues. • Frank Dance’s Helical Spiral (1967): Communication evolves continuously like an expanding helix/coil, building upon past knowledge and experience. |
2. Formal Small-Group Communication Networks (Leavitt) vs Informal Grapevine Chains (Keith Davis)
• Centralized Networks (Best for SIMPLE, routine tasks requiring speed & accuracy):
1. Wheel Network: MOST CENTRALIZED network! All communication flows exclusively through a single central leader/hub; peripheral members cannot talk directly to each other. High speed, high accuracy on simple tasks, very clear leader emergence, but LOWEST member morale/satisfaction!
2. ‘Y’ Network: Slightly less centralized than the Wheel; two members communicate through a central person.
3. Chain Network: Strict vertical hierarchy (A ↔ B ↔ C ↔ D ↔ E); moderate speed, high accuracy, prone to Serial Distortion / Filtering across links.
• Decentralized Networks (Best for COMPLEX, creative problem-solving tasks):
4. Circle Network: Each member communicates only with their two adjacent neighbours (left and right); slow speed, low accuracy, no clear leader.
5. All-Channel (Star / Comcon) Network: MOST DECENTRALIZED network! Every member is free to communicate directly with every other member (zero restrictions, e.g., self-managed brainstorming teams). HIGHEST member satisfaction, best for complex/ambiguous problems, no single leader emergence!
• 1. Single Strand Chain: Person A tells B → B tells C → C tells D in a long sequential line (Least accurate; prone to maximum distortion).
• 2. Gossip Chain (Wheel Pattern): One person (A) actively seeks out and tells EVERYONE else in the group indiscriminately (used for non-job-related personal/social news).
• 3. Probability Chain: Person A transmits information at random to others according to the laws of probability (used when information is mildly interesting but insignificant).
• 4. Cluster Chain (MOST DOMINANT & COMMON Grapevine Pattern in Organizations!): Person A selectively tells a few trusted contacts (B, C, D), and only some of them selectively pass it on to their trusted inner cluster! According to Keith Davis, the Grapevine is 75% to 80% accurate on factual points (though incomplete) and those who actively pass information along the Cluster Chain are called ‘Liaison Individuals’.
3. The Johari Window (Luft & Ingham, 1955), Communication Barriers & Perceptual / Attribution Biases
| Framework / Concept | Core Quadrants / Rules | Exact Exam Definitions & Strategic Implications |
|---|---|---|
| 1. The Johari Window (1955) Created by Joseph Luft & Harrington Ingham (‘Jo’ + ‘Hari’) |
2 x 2 Matrix of Self-Awareness: • Horizontal: Known to Self vs Not Known to Self • Vertical: Known to Others vs Not Known to Others |
• Quadrant 1 — Open Area (Arena): Known to Self AND Known to Others. Goal of interpersonal training is to enlarge the Open Arena through two processes: Self-Disclosure (Exposure) (moving vertically down to shrink the Hidden Area) and Soliciting Feedback (moving horizontally right to shrink the Blind Spot)! • Quadrant 2 — Blind Spot (Blind Area): NOT Known to Self, BUT Known to Others (e.g., an irritating mannerism or unconscious bias you don’t realize you have). Shrunk by Feedback. • Quadrant 3 — Hidden Area (Facade): Known to Self, BUT NOT Known to Others (private feelings, fears, secrets kept hidden from colleagues). Shrunk by Self-Disclosure. • Quadrant 4 — Unknown Area (Dark Area): NOT Known to Self AND NOT Known to Others (untapped latent potential, repressed memories). |
| 2. Barriers to Effective Communication | Semantic, Psychological, Organizational & Personal | • Filtering: Deliberate manipulation/sweetening of unfavourable information by a subordinate so that the boss sees it more favourably (upward distortion). • Semantic Barriers: Bypassed instructions, technical jargon, words with multiple meanings, faulty translations. • Psychological Barriers: Premature evaluation, selective perception, distrust, emotional state, information overload. |
| 3. Harold Kelley’s Attribution Theory (1967) & Perceptual Biases | Judging whether another’s behaviour is Internally Caused (personal effort/character) or Externally Caused (situation/luck) using 3 Factors: | • 1. Distinctiveness: Does the person display different behaviours in different situations? (High Distinctiveness → External Attribution; Low Distinctiveness → Internal Attribution). • 2. Consensus: Does everyone who faces a similar situation respond in the same way? (High Consensus → External Attribution; Low Consensus → Internal Attribution). • 3. Consistency: Does the person respond the same way over time? (High Consistency → Internal Attribution [when Distinctiveness & Consensus are low]). • Major Perceptual Shortcuts / Errors: — Fundamental Attribution Error: Underestimating the influence of external factors and overestimating internal/personal factors when judging others’ failures. — Self-Serving Bias: Attributing one’s own successes to internal factors (ability/effort) and one’s own failures to external factors (bad luck/unfair test). — Halo Effect vs Horn Effect: Drawing a general positive impression (Halo) or negative impression (Horn) about an individual on the basis of a SINGLE characteristic. — Projection vs Stereotyping: Attributing one’s own traits to others (Projection) vs judging someone on the basis of one’s perception of the group to which they belong (Stereotyping). |
🎯 High-Yield Exam One-Liners (Last-Minute Revision Box)
- Shannon and Weaver’s Mathematical Model of Communication (1949) is a Linear transmission model that first introduced the concept of ‘Noise’ (Norbert Wiener later added the Feedback loop).
- David Berlo’s SMCR Model (1960) breaks communication into Source, Message, Channel (the 5 human senses: Hearing, Seeing, Touching, Smelling, Tasting), and Receiver.
- Wilbur Schramm’s Interactive Model (1954) introduced circular two-way feedback and the concept of ‘Field of Experience’ (shared background/culture needed for effective encoding and decoding).
- Dean Barnlund’s Transactional Model (1970) views communication as a simultaneous, continuous process where both participants send and receive verbal/non-verbal cues at the exact same time.
- Among Bavelas and Leavitt’s Formal Small-Group Networks, the ‘Wheel Network’ is the MOST centralized (highest speed/accuracy on simple tasks, strongest leader emergence, but lowest member satisfaction).
- The ‘All-Channel (Star / Comcon) Network’ is the MOST decentralized formal network (every member communicates freely with everyone else; highest member satisfaction and best for complex tasks).
- Keith Davis (1953) classified informal ‘Grapevine’ communication into 4 chains: Single Strand, Gossip, Probability, and Cluster Chain.
- In Keith Davis’s framework, the ‘Cluster Chain’ (where a person selectively shares news only with a few trusted contacts) is the MOST dominant and common grapevine pattern in organizations.
- In the ‘Gossip Chain’ of the grapevine, one individual actively seeks out and tells everyone else in the organization non-selectively.
- The Johari Window was created by psychologists Joseph Luft and Harrington Ingham in 1955 and comprises 4 quadrants: Open Area (Arena), Blind Spot, Hidden Area (Facade), and Unknown Area.
- In the Johari Window, ‘Self-Disclosure (Exposure)’ reduces the Hidden Area (Facade), whereas ‘Soliciting Feedback’ reduces the Blind Spot, expanding the Open Arena.
- In upward organizational communication, ‘Filtering’ refers to a subordinate purposefully manipulating or softening negative information so the superior perceives it more favourably.
- Non-verbal communication dimensions include Kinesics (body language, gestures, facial expressions), Proxemics (use of physical space/distance — Edward T. Hall), Paralanguage (tone, pitch, speed of voice), and Chronemics (use of time).
- According to Harold Kelley’s Attribution Theory (1967), observers judge whether behaviour is Internally or Externally caused based on 3 cues: Distinctiveness, Consensus, and Consistency.
- Under Kelley’s Attribution Theory, Low Distinctiveness + Low Consensus + High Consistency leads to an INTERNAL Attribution (blaming the person), whereas High Distinctiveness + High Consensus leads to an EXTERNAL Attribution (blaming the situation).
- The ‘Fundamental Attribution Error’ is the tendency to underestimate external situational factors and overestimate internal personal factors when judging the behaviour of OTHERS.
- The ‘Halo Effect’ occurs when an evaluator forms an overall positive impression of a person based on a SINGLE positive trait (while the ‘Horn Effect’ forms an overall negative impression from a single negative trait).

❓ Frequently Asked Questions (Exam FAQs)
Q: What are the four sub-fields of non-verbal communication frequently tested in RBI Grade B?
(1) Kinesics — study of body movements, gestures, posture, and facial expressions (Ray Birdwhistell); (2) Proxemics — study of physical space and interpersonal distance zones: Intimate, Personal, Social, Public (Edward T. Hall); (3) Paralanguage (Vocalics) — tone, pitch, volume, speech rate, and pauses; and (4) Chronemics — how time (punctuality, waiting time) is used to communicate status and respect.
Q: What is the difference between the Halo Effect, Stereotyping, and Projection?
The Halo Effect forms an overall positive impression of an individual based on a single admirable trait (e.g., assuming an articulate candidate is also technically brilliant). Stereotyping judges an individual based on generalizations about the demographic/social group they belong to. Projection occurs when a manager attributes their own personal traits, motives, or flaws onto another person.
