What is nonverbal communication primarily based on?

Nonverbal communication is primarily based on gestures, body movements, and facial expressions because these elements play a crucial role in conveying messages without the use of words. Nonverbal cues can express emotions, attitudes, and reactions, often providing context that complements or contradicts verbal communication. For instance, a smile can indicate friendliness, while crossed arms might suggest defensiveness. The subtleties of body language and facial expressions can significantly affect how a message is interpreted and understood during interpersonal interactions, making them essential components of communication in various settings, including therapeutic environments like occupational therapy.

In contrast, the other options focus on forms of communication that rely heavily on verbal or written language, which do not capture the nuances and immediate reactions that nonverbal communication offers. This highlights the importance of understanding nonverbal cues, especially in professions that require empathy and connection, such as occupational therapy.
