What does non-verbal communication include?

Non-verbal communication encompasses a range of methods through which individuals convey messages without the use of spoken or written words. One of the key components of non-verbal communication is facial expressions, which serve as powerful indicators of emotions and reactions. They can convey feelings such as happiness, sadness, anger, and surprise, often communicating more than verbal language can achieve.

In this context, while written text and auditory signals are forms of communication, they do not fall under the umbrella of non-verbal communication. Written text is a verbal form, as it involves the use of words and language, while auditory signals might include sounds or tones that are related to verbal communication but are not inherently non-verbal themselves. Therefore, focusing on facial expressions accurately identifies an essential aspect of non-verbal communication that is crucial for understanding interpersonal interactions and behaviors.
