Lecture 02: Communication Process and Roadblocks

Summary

Key Points

• The primary functions of communication are to inform, persuade, motivate, and entertain, each requiring clarity, credibility, and audience interest. 17:18
• Public speaking can shape audiences through persuasive language, emotional appeal, and the strategic use of non‑verbal signals. 24:16
• Human communication follows a structured pattern of sender, message, channel, receiver, and effect, and includes both verbal and non‑verbal cues such as gestures and facial expressions. 25:07
• Selecting a medium that matches the receiver’s access and need for feedback—media richness—enhances message effectiveness and reduces misunderstandings. 27:45
• Linguistic barriers arise from unfamiliar languages, jargon, or informal tones that prevent the audience from understanding the message. 36:06
• Psychological, cultural, and gender differences—such as ego, fixed mindsets, stereotypes, or superstitions—can distort interpretation if not respected. 39:32
• Physical and technical obstacles like noise, poor acoustics, or faulty equipment hinder communication and must be mitigated. 40:33
• Overcoming barriers requires identifying the audience, tailoring the message, encouraging open feedback, reducing hierarchical distance, and adhering to ethical principles of honesty, patience, and generosity. 43:43
