Define non veriable communication?

Nonverbal communication between people is communication through sending and receiving wordless cues.
It includes the use of visual cues such as body language (kinesics) , distance (proxemics) and physical environments/appearance, of voice (paralanguage) and of touch (haptics).[1] In can also include chronemics (the use of time) and oculesics (eye contact and the actions of looking while talking and listening, frequency of glances, patterns of fixation, pupil dilation, and blink rate).
Just as speech contains nonverbal elements known as paralanguage, including voice quality, rate, pitch, volume, and speaking style, as well as prosodic features such as rhythm, intonation, and stress, so written texts have nonverbal elements such as handwriting style, spatial arrangement of words, or the physical layout of a page. However, much of the study of nonverbal communication has focused on interaction between individuals,[2] where it can be classified into three principal areas: environmental conditions where communication takes place, physical characteristics of the communicators, and behaviors of communicators during interaction.
Nonverbal communication involves the processes of encoding and decoding. Encoding is the act of generating the information such as facial expressions, gestures, and postures. Decoding is the interpretation of information from received sensations from previous experiences.[2]
Only a small percentage of the brain processes verbal communication. As infants, nonverbal communication is learned from social-emotional communication, making the face rather than words the major organ of communication. As children become verbal communicators, they begin to look at facial expressions, vocal tones, and other nonverbal elements more subconsciously.
