Listening is a key communication skill that involves receiving, understanding, remembering, and responding to spoken messages. There are five stages to the listening process: receiving the message, understanding meaning, remembering content, and responding with feedback. Effective listening enhances productivity, improves relationships, avoids conflicts, and adds to one's image and personality. Barriers to listening include prejudgments, lack of focus, and distractions. Developing active listening skills like maintaining eye contact and asking questions can help overcome these barriers.
