Posture and movement are crucial aspects of which type of communication technique?

The correct choice is nonverbal communication because posture and movement are integral components of how we convey messages without using words. Nonverbal cues include body language, facial expressions, gestures, and overall posture, which can significantly influence how a message is interpreted. For example, an open posture can signal confidence and receptiveness, while crossed arms might suggest defensiveness or resistance.

These nonverbal elements can either reinforce or contradict what is being said verbally, making them a crucial aspect of effective communication. This emphasizes the importance of being aware of one's body language and movements during interactions, as they can communicate feelings and attitudes just as powerfully as spoken language.

Other options, such as verbal, written, and visual communication, do not focus on body language and movement in the same way that nonverbal communication does, making them less relevant in the context of this question.
