What is the term for using facial expressions, body positions, and vocal inflections to convey messages?

The term that encompasses the use of facial expressions, body positions, and vocal inflections to convey messages is non-verbal communication. Non-verbal communication is a broad concept that includes various forms of communication that do not rely on words, such as gestures, posture, eye contact, and tone of voice. These elements work together to provide context and emotion to spoken words and often can convey information more powerfully than verbal messages alone.

Body language is a significant component of non-verbal communication, focusing specifically on the physical behaviors that convey emotional states or intentions. While body language is a vital aspect of non-verbal communication, the latter also includes other non-physical cues such as tone of voice and facial expressions, which are not fully encapsulated by the term "body language."

Verbal communication refers specifically to the use of spoken or written words, while written communication is restricted to text. Neither of these options incorporates the non-verbal aspects that play a crucial role in how messages are interpreted in interpersonal interactions. Thus, understanding non-verbal communication is essential for effective interaction and conveys a rich array of information that can enhance or contradict what is being said verbally.
