Which of the following is an exclusive element identified by Wilbur Schramm in the process of mass communication?

The exclusive element Wilbur Schramm identified in the process of mass communication is the field of experience.

By this he meant the store of orientation, culture and prior knowledge each party brings to the exchange.

Communication succeeds to the degree that the sender's and receiver's fields of experience overlap.

The sender was already present in earlier linear models and so is not the element special to Schramm.

The receiver too features in the basic sender-message-receiver chain and is not his distinctive contribution.

The channel likewise appears across many models, whereas the field of experience is the concept Schramm added to explain shared meaning.
