"A symbolic process in which communicators try to convince other people to change their attitudes or behaviors regarding an issue through the transmission of a message in an atmosphere of free choice"
After looking online, there are different but similar views of persuasion techniques. Emotional layer holds the most power of persuasion. After all most people make decisions based on emotions.In order to persuade someone you must understand them. It is important to understand that each person responds differently, either strongly emotionally or visually. You should adjust techniques based on the kind of mind you are dealing with.
For a simple way of looking a persuasion: you want to create a need, appeal to social needs, and used loaded words and images. When creating a need you want to appeal to a person's fundamental need for shelter, love, self-esteem and self-actualization. Appealing to social needs is the appealing to the need to be popular, prestigious, or similar to others. You want to use the power of positive words, such as "new and improved" or "all natural." Not only do you want your words and imagery to be positive, but have them have action with words such as "do that" or "be this."
Most of these techniques I was already familiar with, however these next ones I did not know about....
Mirror-based techniques = matching a person's language (the words they use more often) and body language.
Rhetorical questions = asking them a question not only engages the person and automatically makes them receptive, but also makes them feel that they are making the decision.
and of course
Eye contact = creating eye contact with a person develops trust
