Which movement indicates agreement in communication?

Nodding the head is a universally recognized gesture indicating agreement. This nonverbal cue often conveys understanding, affirmation, or support during communication. When someone nods their head while another person is speaking, it reinforces a positive interaction and shows that they are engaged and in alignment with what is being expressed. The act of nodding provides immediate feedback in conversation, signaling attentiveness and validation of the speaker's message.

In contrast, other movements mentioned, such as holding a hand up, crossing arms, and looking away, can signify different emotions or states. Holding a hand up might suggest a desire to interject or pause the conversation. Crossing arms can indicate defensiveness or resistance, and looking away may denote disengagement or disinterest. These gestures do not convey agreement in the same clear manner as nodding the head does.
