backchannel communication

Backchannel communication refers to the informal or secondary signals, cues, or conversations that occur alongside main communication, providing feedback or clarification. It includes gestures like nodding, facial expressions, or words like "uh-huh" during a conversation, which let the speaker know you’re engaged or understanding their message. It also encompasses electronic responses, such as quick responses in chat, emoji reactions, or verbal affirmations in meetings. These cues support effective communication by conveying attentiveness, agreement, or confusion without interrupting the primary dialogue.
