This document discusses communication and effective communication skills. It notes that communication is a two-way process that involves both listening and expressing. Barriers to communication like cultural differences, language issues, and distractions can lead to misunderstandings. Effective communication skills include making eye contact, using body language, summarizing what has been said, and encouraging the other person to continue. Selective listening and barriers like noise, time constraints, and discomfort with a topic can negatively impact communication.
