Which form of communication includes elements such as posture, facial expression, and tone of voice?

The correct answer is non-verbal communication. This form of communication encompasses a variety of cues that express feelings and attitudes without the use of words. Elements such as posture, facial expression, and tone of voice play a significant role in conveying messages. For example, a positive posture can indicate openness and confidence, while a frown or crossed arms might suggest defensiveness or disinterest. Similarly, tone of voice can affect the interpretation of the spoken message, adding nuance and emotional context that words alone might not convey. Understanding non-verbal cues is essential for effective communication, as they often provide insight into a person's true feelings or intent beyond what is being explicitly stated.
