This theory developed by Walter Fisher, which the concept of this theory is about narration or the story telling which is the effective method to communicate. You can persuade, or persuasion takes place when peoples past experiences influence our need for communication and also base our behaviour.
Thus narrative paradigm is very helpful in analysing the nature of human communication. This narrative paradigm cam interpret whether verbal or non-verbal communication that can interprets arranged logically to generate a meaning. This communication process is influenced by the experiences and other factors from the past. The concept upholds the idea that communication happens between a narrator and the listener in the form of a story.
Example is people listen on the story of which is narrated from the past which they tend to listen on the stories narrated long ago because it is part of our culture back then, and do not tend to listen on the previous research which is lately narrated. And the credibility and reality of the storiea told before and people believes that it is true.
