Opening Communication
In many interpersonal encounters, the first few minutes are extremely important as first impressions have a significant impact on the success of further communication.
Everyone has expectations and norms as to how initial meetings should proceed and people tend to behave according to these expectations. If these expectations are mismatched, communication will not be effective or run smoothly, and some form of negotiation will be needed if relations are to continue.
At a first meeting, formalities and appropriate greetings are usually expected: such formalities could include a handshake, an introduction to yourself, eye contact and discussion around a neutral subject such as the weather or your journey may be useful. A friendly disposition and smiling face are much more likely to encourage communication than a blank face, inattention or disinterested reception.
Reinforcement
The use of encouraging words alongside non-verbal gestures such as head nods, a warm facial expression and maintaining eye contact, are more likely to reinforce openness in others.
The use of encouragement and positive reinforcement can:
Encourage others to participate in discussion (particularly in group work)
Signify interest in what other people have to say
Pave the way for development and/or maintenance of a relationship
Allay fears and give reassurance
Show warmth and openness.
Reduce shyness or nervousness in ourselves and others.
