Body language other than any kind of communication is non-verbal. It uses physical behavior to express or convey information. This includes facial expressions, body posture, gestures, eye movement, touch and the use of space.
It is important to note that different body parts also contribute to one’s physical behavior. The ears, eyes, hands, legs always indicate a form of non-verbal communication.
It does not have a particular grammar or meaning to the behavior. Other than sign language that have specific meanings. However, interpretations may vary from cultures, countries or communities.
Someone’s expression may be interpreted different using the different signals of the body language for instance; confidence, first impression, lying, or even disengagement have signals that can easily indicate it.
Someone who is confident is seen through their body language. One’s physical behavior always helps with first impressions. This can be shown or indicated by the following;
Posture; standing tall with shoulders back.
Eye contact; solid with a “smiling” face.
Gestures with hands and arms; purposeful and deliberate.
Speech; slow and clear.
Tone of voice; moderate to low.
Body language also indicates one’s behavior or honest. That is to say, through body language, one can easily see a person lying. For example;
Eyes maintain little or no eye contact, or there may be rapid eye movements, with pupils constricted.
Hand or fingers are in front of his or her mouth when speaking.
His or her body is physically turned away from you, or there are unusual/unnatural body gestures.
His or her breathing rate increases.
Complexion changes such as in color; red in face or neck area.
Voice changes such as change in pitch, stammering, throat clearing.
Therefore, one has to clearly study one’s physical behavior for better judgement of them.
