1. Listening involves hearing words and sentences and properly matching the mental faculties of the sender and receiver, requiring concentration.
2. There are three basic steps to listening: hearing, understanding, and evaluating. Hearing just catches the points, understanding creates meaning, and evaluating determines if it makes sense.
3. Types of listening include discriminative listening which focuses on specific sounds, marginal listening which focuses on important parts while neglecting additions, and projective listening which matches the listener's ideas to the speaker's message. Active listening incorporates full attention and feedback.
