Listening comprehension involves actively receiving, constructing meaning from, and responding to spoken and non-verbal messages. There are three main types of listening: active listening which involves understanding, proper interaction and feedback; selective listening where only parts are remembered; and ignoring listening which does not involve listening at all. Effective listening involves several stages from hearing to remembering. Barriers to listening include physical barriers like noise, physiological barriers like health issues, and psychological barriers like personal anxiety. People often do not listen effectively because they are distracted, recall little of what is said, and spend less than half their time actually listening. To improve listening, one should stop talking, ask questions, maintain eye contact and listen creatively.
