Schramm's Model of Communication Wilbur L. L. Schramm was a forefather in the development of a basic model of communication.. His model is a derivation of the Shannon-Weaver transmission communication model of communication. The Shannon-Weaver model proposed six elements of communication:
source encoder message channel decoder receiver
Wilbur Schramm's 1954 model expands on this thinking by emphasizing the process of encoding encoding and and decoding decoding the message. message. Schramm Schramm envisioned envisioned this process as a two-way circular communication between the sender and receiver. Where the Shannon-Weaver model is a more mathematical and technological one, Schramm incorporates incorporates the study of human behavior in in the communication process. process . In addition to the six elements above, Schramm has included these concepts:
Feedback - information that comes back from the receiver to the sender and tells him how well he is doing. Diagram of Schramm's feedback loop
Field of Experience - an individual's beliefs, values, experiences and learned meanings both as an individual or part of a group.

Dr. Schramm suggests that the message can be complicated by different meanings learned by different people. Meanings can be denotative or connotative. Denotative meanings are common or dictionary meanings and can be roughly the same for most people. Connotative meanings are emotional or evaluative and based on personal experience. A message can also have surface and latent meanings. Other characteristics of messages that impact communication between two individuals are: intonations and pitch patterns, accents, facial expressions, quality of voice, and gestures. The successful transmission of a message depends on whether this message will be accepted over all the competing messages. Schramm's model of communication also allows for the process of interpreting the message. This process is influenced by the presence of both physical (phone, tv, sirens, etc.) and semantic (distractions, age, attitudes, etc.) noise. Dr. Schramm believed that all of these elements were important functions of communication in society. He felt that people in a society need information on their environment and methods of communicating in order to make decisions. Most importantly we need "places to store the accumulated knowledge and wisdom of a society and this is why we have libraries" (Schramm, 1963, pg. 14). Within a library, all of these elements of Wilbur Schramm's communication model are useful in addressing problems with conducting a reference interview. This model provides the rationale to solve the problem presented in this project. Solution to the Problem Schramm’s model seemed best for solving this particular communication problem because of the
cyclical nature of the interaction between patron and librarian at the reference desk. Schramm's model emphasizes two way communication between the individuals. Normally more than one question is needed to ascertain exactly what a patron wants. The process of asking open ended questions to gain knowledge of what the patron is looking for allows for the possibility of constructive feedback. Even if only one question is asked, body language sends other signals so that there is always more than one message. Schramm is the first to include the field of experience which is a key factor in the lack of communication in our intital situation where there is not enough information given. According to Schramm, “The sender can encode or the receiver can decode only
in terms of the experience he has had.” Therefore, the patron does not know that s/he must
differentiate between the history of Spain or travel in Spain when s/he asks for books on Spain. The reference librarian who has just been answering historical questions for someone else would naturally be quick to direct the patron to history books. The lack of further questioning brings the cycle of feedback to a halt.
This diagram interprets Schramm's communication model using figures (instead of circles) to show human communication between two people. For our problem one figure represents the librarian and the other the patron. The difference between Schramm's graphic representation and Infotech's is the use of different colors to distinguish between the two people, the messages and the field's of experience. The varying type face suggests the processing by each person to decode-interpretencode the message. The diagram with colo r-coded differences comes from Schramm's emphasis on how people are different. He explains that we will encode messages based solely on our experience and group affliliations which will not be the same for any two people. The diagram represents Schramm's communications model by using two human figures and various color changes to signify the way a message or signal changes, including the limitations of personal fields of experience, sensory receptors, and noise.
Many patrons come into a library with a predisposed notion of a prudish and unfriendly librarian. This attitude combined with an intimidation of computers, a lack of knowledge of the cataloging system, a possible language and cultural barrier, can produce a frustrated patron who is afraid to ask for help. Even patrons who feel comfortable in a library setting may find it diff icult to approach the reference desk. Librarians recognize that library users often ask their initial questions in incomplete and unclear terms. Conducting a reference interview is the best process of extrapolating information from a patron and a good example of Schramm's model in action.
The patron looking for "books on Spain" would have been better served by a friendly, approachable librarian who asked specific questions designed to understand the message sent:
What would you like to find out about Spain? How are you planning on using this information?
Is this for a project? Because if it is for a school project the answer may be different than if it is for another purpose. The use of these open ended questions allows the librarian to clarify the problem, locate the information required to answer the question, find a solution and communicate the answer to the patron. This technique effectively sets up the first cycle of communication. The question then can be asked, "Is this the information you were looking for?" If the patron says "no" then the process of encoding and decoding the patron's message and providing feedback can begin again until a solution is found. The motivation behind the question is more important at this point in bringing the librarian and patron closer to a common area of understanding. Continuing with this two-way question and answer process will ensure that the patron is satisfied with the information provided.
Schramm's model of communication is useful for librarians helping patrons find the information they need. It is the librarian’s job to be empathetic and put the patron at ease with the proper body
language and communication skills. At the reference desk the librarian needs the proper tools and skills in order to be empathetic and decode the patron’s request so that a positive reference interview can take place and the patron leaves satisfied. Using Schramm’s model of communication
will help the librarian co nduct a positive reference interaction. Many aspects of Schramm’s model can be found in the “RUSA Reference Guidelines for Behavioral Performance of Reference and Information Service Providers.”
