This document discusses demonstrative communication, which involves sending and receiving messages through nonverbal means like facial expressions, body language, and tone of voice. Effective demonstrative communication requires active listening skills - making eye contact, being attentive without distractions, observing body language, and avoiding side conversations. It also involves providing feedback through paraphrasing, reflecting on what was said, and asking clarifying questions. In contrast, ineffective demonstrative communication can happen when senders overload receivers with information, speak too fast, or use an inappropriate or hostile tone of voice.
