Interpersonal Communication Models

Why This Matters

As a leader, every interaction you have—whether it's a one-on-one with a direct report, a team meeting, or a difficult conversation—is shaped by how communication actually works. These models aren't abstract theories; they're frameworks that explain why some messages land and others fall flat, why certain relationships deepen while others stall, and why context changes everything. You're being tested on your ability to diagnose communication breakdowns and choose the right approach for the situation.

Understanding these models means recognizing that communication is never just about what you say. It's about how meaning gets constructed, who holds the power in an exchange, and what barriers stand in the way. The models here progress from simple transmission views to complex relational theories—and that evolution mirrors how leadership communication has matured. Don't just memorize definitions—know which model applies when a message fails, when trust needs building, or when a relationship needs repair.

Linear and Component Models

These foundational models treat communication as a process with identifiable parts. They help you isolate where breakdowns occur—is it the sender, the channel, or the noise?

Shannon and Weaver's Model

• Linear transmission framework—sender encodes a message, sends it through a channel, and receiver decodes it, with noise as any interference
• Noise identification is the key leadership application; noise can be physical, semantic, or psychological and must be anticipated
• Limitation for leaders: assumes one-way communication, which rarely reflects real workplace dynamics

Berlo's SMCR Model

• Source credibility matters—the sender's knowledge, attitudes, and communication skills directly affect message reception
• Channel selection shapes interpretation; choosing email vs. face-to-face isn't neutral, it changes how the message lands
• Receiver variables including listening skills, prior knowledge, and cultural background determine whether understanding occurs

Interactive and Transactional Models

These models recognize that communication flows both ways and meaning emerges through exchange. Feedback isn't optional—it's how you know if communication actually happened.

Schramm's Interactive Model

• Fields of experience must overlap for understanding; shared context, vocabulary, and background create common ground
• Feedback loops transform communication from broadcast to dialogue, allowing real-time adjustment
• Meaning is co-created—it doesn't exist in the message itself but emerges from the interaction between communicators

Transactional Model of Communication

• Simultaneous sending and receiving—while you speak, you're also reading reactions, making both parties active participants at all times
• Context dependency means the same words carry different weight depending on environment, relationship history, and power dynamics
• Communication is continuous—every interaction builds on previous ones and shapes future exchanges

Developmental and Relational Models

These models explain how communication changes over time and how relationships deepen through strategic disclosure. Leadership isn't just about single messages—it's about building trust across many interactions.

Helical Model

• Spiral structure represents how communication builds on itself—each interaction adds a layer to the relationship
• Past interactions shape present ones; you can't ignore history when communicating with someone you've worked with before
• Growth orientation makes this model useful for understanding mentorship, coaching, and long-term team development

Social Penetration Theory

• Onion metaphor—relationships develop through layers, moving from superficial exchanges to deeper, more intimate disclosure
• Reciprocity drives depth; self-disclosure must be mutual for relationships to progress
• Trust precedes vulnerability—leaders who expect deep honesty without first creating safety will hit walls

Johari Window Model

• Four quadrants of awareness: open (known to self and others), blind (unknown to self), hidden (known only to self), and unknown (undiscovered by anyone)
• Feedback expands awareness—others can reveal your blind spots if you create conditions for honest input
• Self-disclosure builds trust—strategically sharing from your hidden area moves information into the open, strengthening relationships

Uncertainty and Expectation Models

These models address the psychological dynamics of communication—how we manage the unknown and respond when expectations are violated. Leaders who understand these dynamics can navigate ambiguity and recover from missteps.

Uncertainty Reduction Theory

• Information-seeking strategies: passive (observing), active (asking others), and interactive (direct conversation) approaches to learning about someone
• Uncertainty creates anxiety—new team members, unfamiliar stakeholders, and organizational changes all trigger this dynamic
• Predictability builds comfort; effective onboarding and clear communication reduce the cognitive load of uncertainty

Expectancy Violations Theory

• Violations can be positive or negative—a leader who's surprisingly approachable violates expectations in a good way; one who's unexpectedly harsh does the opposite
• Relationship and reward value determine how violations are interpreted; high-status communicators get more latitude
• Social norms set baselines—you can't strategically violate expectations if you don't first understand what's expected

---

Cognitive and Psychological Models

These models explain internal processes that affect how messages are processed and accepted. What happens in someone's mind matters as much as what you say.

Cognitive Dissonance Theory

• Psychological discomfort arises when beliefs, attitudes, or behaviors conflict—and people are motivated to resolve it
• Resolution strategies include changing beliefs, seeking new information, or minimizing the importance of the conflict
• Leadership application: when delivering feedback that conflicts with someone's self-image, expect resistance and plan for it

Self-Check Questions

1. A new employee seems hesitant to share ideas in meetings. Which two models best explain what might be happening, and what would each suggest as an intervention?

2. You sent a clear email, but your team misinterpreted the message. Using Shannon-Weaver and Berlo's SMCR, identify at least three possible sources of the breakdown.

3. Compare and contrast Social Penetration Theory and the Johari Window. How would you use each to improve a stalled working relationship with a peer?

4. A leader known for being formal suddenly cracks jokes in a meeting. Using Expectancy Violations Theory, explain how this might be received differently by a direct report versus a senior executive.

5. Your feedback to a high performer about a development area was met with defensiveness. Which model explains their reaction, and what communication strategy might help them process the information?
