As a rule, verbal communication must always correspond with a non-verbal action within a conversation. If verbal communication happens to contradict the non-verbal aspect, there is potential confusion, which can cause problems in relationships and organizational set ups. For example if a husband expresses his love verbally to a wife, but doesn't allow the corresponding actions to follow, then there is the likelihood the meaning of the conversation will be misconstrued.
It is important to choose your diction correctly to project your thought. Choosing the right words will clearly allow the listener to grasp the full meaning of the message being passed. This will make communication more effective and smooth. Be careful not to use words that are ambiguous, have double-meanings or are contradicting.
It is crucial not to allow your emotions to get in the way in the event of communicating. Emotions will consequently impact your ability to pass on information. It is unnecessary to show anger if you disagree with a view or feel passionately about a subject. Good communication allows for healthy debates and not defensiveness and introduction of anger. Listening to the other party's view and learning to understand their point of view will ensure dialogue is healthy.
However your positive emotions should also be kept in check. Showing extreme happiness, joy or excitement can impede the smooth transfer of a message. It is important there's a fair balance of emotions throughout.
When you communicate, there must be a good balance between what you say and what you hear. Otherwise, you leave with nothing other than what you already know. The main reason for communication is to share ideas and thoughts and be able to build up on already accrued knowledge. You must pay attention to your listener and don't assume you know what the listener means. Keep an open mind always to understand the viewpoint of others.
