Nonverbal communication is the transmission of messages or signals through a nonverbal platform such as eye contact, facial expressions, gestures, posture, and body language. It includes the use of social cues, kinesics, distance and physical environments/appearance, of voice and of touch. It can also include the use of time and eye contact and the actions of looking while talking and listening, frequency of glances, patterns of fixation, pupil dilation, and blink rate. Nonverbal communication involves the conscious and unconscious processes of encoding and decoding.
Encoding is defined as our ability to express emotions in a way that can be accurately interpreted by the receiver.
Decoding is called “nonverbal sensitivity”, defined as the ability to take this encoded emotion and interpret its meanings accurately to what the sender intended.
Encoding is the act of generating information such as facial expressions, gestures, and postures. Encoding information utilizes signals which we may think to be universal. Decoding is the interpretation of information from received sensations given by the encoder. Decoding information utilizes knowledge one may have of certain received sensations. For example, in the picture above, the encoder holds up two fingers, and the decoder may know from previous experience that this means two.
There are some “decoding rules”, which state that in some cases a person may be able to properly assess some nonverbal cues and understand their meaning, whereas others might not be able to do so as effectively. Both of these skills can vary from person to person, with some people being better than others at one or both. These individuals would be more socially conscious and have better interpersonal relationships.
An example of this would be with gender, woman are found to be better decoders than men since they are more observant of nonverbal cues, as well as more likely to use them.
Common types of non-verbal communication are following:
Facial Expressions : Facial expressions are responsible for a huge proportion of nonverbal communication. Consider how much information can be conveyed with a smile or a frown. The look on a person’s face is often the first thing we see, even before we hear what they have to say.
Gestures : Deliberate movements and signals are an important way to communicate meaning without words.2 Common gestures include waving, pointing, and using fingers to indicate numeric amounts. Other gestures are arbitrary and related to culture.
Paralinguistics : Paralinguistics refers to vocal communication that is separate from actual language. This includes factors such as tone of voice, loudness, inflection, and pitch. Consider the powerful effect that tone of voice can have on the meaning of a sentence. When said in a strong tone of voice, listeners might interpret approval and enthusiasm. The same words said in a hesitant tone of voice might convey disapproval and a lack of interest.
Body Language and Posturer : Posture and movement can also convey a great deal of information.4 Research on body language has grown significantly since the 1970s, but popular media have focused on the over-interpretation of defensive postures, arm-crossing, and leg-crossing, especially after publishing Julius Fast’s book Body Language.
Proxemics : People often refer to their need for “personal space,” which is also an important type of nonverbal communication. The amount of distance we need and the amount of space we perceive as belonging to us is influenced by a number of factors including social norms, cultural expectations, situational factors, personality characteristics, and level of familiarity.
Eye Gaze : The eyes play an important role in nonverbal communication and such things as looking, staring and blinking are important nonverbal behaviors. When people encounter people or things that they like, the rate of blinking increases and pupils dilate. Looking at another person can indicate a range of emotions including hostility, interest, and attraction.
How to Overcome Eye Contact Anxiety
Haptics : Communicating through touch is another important nonverbal behavior. There has been a substantial amount of research on the importance of touch in infancy and early childhood. Harry Harlow’s classic monkey study demonstrated how deprived touch and contact impedes development. Baby monkeys raised by wire mothers experienced permanent deficits in behavior and social interaction. Touch can be used to communicate affection, familiarity, sympathy, and other emotions.
Appearance : Our choice of color, clothing, hairstyles, and other factors affecting appearance are also considered a means of nonverbal communication.8 Research on color psychology has demonstrated that different colors can evoke different moods. Appearance can also alter physiological reactions, judgments, and interpretations.
Artifacts : Objects and images are also tools that can be used to communicate nonverbally. On an online forum, for example, you might select an avatar to represent your identity online and to communicate information about who you are and the things you like
A Word From Verywell : Nonverbal communication plays an important role in how we convey meaning and information to others, as well as how we interpret the actions of those around us.
