backchanneling cues such as yes and uh-huh come under which stage of listening
Backchannel (linguistics) Due to research development in recent years, backchannel responses have been expanded to include sentence completions, requests for clarification, brief statements, and non-verbal responses and now fall into three categories: non-lexical, phrasal, and substantive.[3] A non-lexical backchannel is a vocalized sound that has little or no referential meaning but still verbalizes the listener's attention. In English, sounds like "uh-huh" and "hmm" serve this role. Phrasal backchannels most commonly assess or acknowledge a speaker's communication with simple words or phrases (for example, "Really?" or "Wow!" in English). Substantive backchannels consist of more substantial turn-taking by the listener and usually manifest as asking for clarification or repetitions.
