    LEARNING OUTCOMES

    • Identify and define the basic components of different communication models.
    • Discuss how various communication models can be applied to real-world situations.

    BASIC PROCESS MODELS OF COMMUNICATION

    Imagine you are learning how to build your own computer. You are familiar with how to use computer technology and on a functional level you understand how computers work. Have you ever taken the time to examine and learn the process of computing to understand the series of actions necessary to make them work?

    Learning about the communication process is like learning about any other process. We are familiar with different ways we communicate through channels like the spoken word or text messaging. What are some of the processes that shape communication? How can we understand these processes to become more competent communicators?

    Understanding interpersonal communication is enhanced by internalizing processes of interaction. To continue this process, we turn to interaction models that elucidate the unique phenomena involved in human communication. The basic process models covered in this module do not include every model but focus on important models pertinent to grasping communication.

    Transmission models

    Transmission models of communication focuses on the transportation of message(s) from one communicator to another to disseminate knowledge over space (Sapienza, et. al., 2016). Transmission models are focuse on communication as a linear process where the sender is projecting a message to a target without much consideration to ongoing process or feedback loops as described in other models.

    In 1949 mathematician Claude Shannon and engineer Warren Weaver developed a basic transmission model of communication that serves as a foundational tool to understanding the communication process (Shannon & Weaver, 1949). The Shannon and Weaver model breaks communication down into five parts- Sender, Encoder, Channel, Decoder, Receiver (Figure 1).

    Figure \(\PageIndex{1}\): Shannon-Weaver’s Model of Communication

    Note. Notice how the sender and receiver both undergo the transaction simultaneously.

    The sender is the original information source of the message. Encoder refers to the transmitter that converts the message into signals. Channel is the means by which the message is conveyed. Decoder is the location of the signal that converts the message. Receiver is the intended target of the message. As a message passes from sender to receiver, it can be impeded by noise, which can alter or distort the message meant for the receiver.

    For example, let’s say that Blake is a chemistry professor who is explaining the periodic table in class. Blake would represent the sender or information source.

    Blake’s means of encoding or transmitting would be his brain converting the ideas into a message. The channel professor Blake is using is their voice accompanied by writing a diagram on the board.

    The decoders would be the ears and eyes of the students in the class. The receivers or destinations are the brains of the students. In this chemistry class there is an abundance of noise that is inhibiting the transmission of the message that Professor Blake is sending. Jamie and Dakota are mischievous class clown types who are intent on derailing the learning experience by making various animal noises at their lab station.

    Alex is more interested in watching YouTube videos on a phone with one earbud in and one out, feigning attention to Professor Blake’s message. Meanwhile, Jordan who is desperately attempting to learn chemistry is internally enraged at the inattentive classmates and periodically sneers and makes gestures imploring others to be silent.

    In mass mediated communication, messages are encoded into various channels. In a State of the Union address, the President of the United States has a target audience- the American public. The President and his team craft the speech over a period to be delivered to Congress and broadcast live to a television audience. This speech will be simultaneously broadcast through radio and internet channels.

    The process described above differs from the immediate interpersonal context of transaction because it is not as dependent on immediate feedback. Yes, people will respond in real time through discussions and social media posts. However, this has no impact on the original message created as it was designed as a one-way communication event. How the President’s message is interpreted will differ significantly due to subjective interpretations based on identity.

    Even in a process that is more one-way than immediately interactive, human beings are still communicating meaning to each other. Understanding the differences in structure, code and channel help us gain insight in how these processes influence our interactions on a macro and micro level. In a State of the Union address the President is speaking to the entire country with specific ideas and declarations to embolden ardent supporters.

    All of these examples show how noise can impede the quality of a message. Now that we have briefly discussed the Shannon and Weaver model, we will turn to Berlo’s adaptation of the Shannon and Weaver model.

    Berlo’s SMCR Model

    In 1960, David Berlo expanded the Shannon and Weaver model to more accurately reflect the communication process (Turaga, 2016). Berlo’s model is divided into four basic components: source, message, and channel and receiver. In each pillar of Berlo’s model are subcategories that describe the interaction process in greater detail (Figure 2).

    Figure \(\PageIndex{2}\): Berlo’s SMCR Model of Communication

    Source

    The source is the origin of the message. Source can also be analogous to sender as the messenger provides the initial context of the interaction. The source must have basic communication skills such as reading, speaking and listening to be an effective communicator. In addition, the attitude of the sender is important in developing a relationship with the audience. The sender must also be knowledgeable regarding the subject matter she/he is discussing.

    Inherent in every message are the social systems (values, beliefs, religion) the sender is immersed in, which impacts the rhetorical choices the sender makes. Culture also influences the sender’s message as messages can be interpreted differently depending on an individual’s cultural background.

    Message

    The first element to consider in a message is content. What is included in the message from beginning to end? Elements are additional aspects such as gestures and signs, that accompany the transmission of the message. Treatment is the way the message is sent, similar to gift wrapping of a present where the message itself is wrapped inside the treatment.

    Structure refers to the framework of the message or how the message is constructed. Code refers to form, i.e. text or language that the message is conveyed in.

    Channel

    Similar to the Shannon and Weaver model, channel refers to the medium in which the message is delivered. In order for the message to be received it must be perceived by one or more of the five senses: sight, hearing, smell, touch or taste. Most often, messages are conveyed through sight and sound but non-verbal elements such as touch, taste or smell can also convey meaning, as any chef or dancer will tell you.

    Receiver

    Receiver is the person, destination or decoder of the message. As we discussed with the sender, attitude, knowledge, social systems and culture must be considered in understanding how this process works.

    Berlo’s model is a simplistic description of the communication process. All messages begin with a person of origin and destination. Let’s return to our scenario involving Professor Blake’s chemistry class. Professor Blake needs to relay and important message to students involving next week’s test. Blake wants to inform them about changes to the study guide but has noticed a few of the students were absent in the last class meeting.

    Professor Blake is the source and the message describes the important changes. To ensure continuity, Blake decides to send the message through the channel of email. The message is marked “URGENT” in capital letters to increase the chances the students will open it.

    The tag “URGENT” is an example of an element to punctuate the message. Despite the fact Blake has been frustrated lately with some of the students in class, Blake makes sure to use an upbeat tone to not display frustration. Good teachers need to be balanced and exhibit patience.

    Always remember attitude is important in developing and maintaining a relationship with the audience. If Professor Blake does not get the desired feedback then changes may need to be made to the communication channel or code.

    Transactional model

    The transactional model of communication is a more simplified model for understanding the communication process. Developed by Dean Barnlund (2008), the transactional model can be understood as a circular model of communication, more focused on the simultaneous interaction of participants than a linear process (Figure 3).

    Both sender and receiver are continually affected by the messages being sent and received back and forth. The transactional model reflects an exchange of ideas, meaning and feelings. Similar to a relationship between a business owner and a client, communication depends on the giving and receiving of information or content.

    Figure \(\PageIndex{3}\): Transactional Model of Communication

    Note. Observe that the Transactional Model recognizes feedback in communication, suggesting the joint activity and meaning-making that occurs between interlocutors.

    In the transactional model, communication is simultaneous and interdependent. Riley is a physical therapist who helps clients recover from injuries. Much of Riley’s job is to understand the pain and discomfort of the clients in order to effectively help them recuperate. In this situation, both Riley and the clients must exchange information in order to accomplish mutual goals. Riley wants to help the clients recover and the clients want to feel better.

    Riley’s newest client, Cameron is a challenge to help. Cameron has suffered from several injuries from playing soccer, including a few concussions. The problem is Cameron does not like to verbally disclose the injuries because of the desire to continue playing. This unwillingness to disclose injuries makes it difficult for Riley to properly treat Cameron.

    In this situation, both Riley and Cameron are dependent on each other to reach the desired outcome. They both have different goals. While Riley wants to do the job properly and ensure Cameron’s health and safety, Cameron is reluctant to disclose information in order to stay on the field. Each person in this situation must mitigate the other’s feelings, ideas and goals in real time to come to a shared meaning or mutually beneficial outcome.

    The transactional model of communication emphasizes the role of feedback and the ongoing negotiation of participants in an interpersonal context. How is communication different in situations that are less personal and immediate? To help answer this question, we turn to the transmission model of communication.

    Now that we have discussed the idea of communication as transmission we turn to a discussion of rituals. Often, our communication practices depend on a repetitive dynamic of sharing meaning through symbolic interaction and the reinforcement of cultural values.

    Ritual model

    The ritual model of communication focuses on the sharing of information and preserving that information over time (Figure 5). Ritual communication relies on shared belief systems (Carey, 2009).

    Figure \(\PageIndex{4}\): Ritual model

    Note. The ritual model emphasizes how communicators draw from outside sources to establish the meaning of everyday messages.

    Developed by James Carey, the ritual model considers symbolism, shared practices and codes which produce a cultural identity. An audience is more participant than receiver in an ongoing dance of familiar steps. Communication is not a simple process of sending a message to a receiver. Communication is shaped by the process itself, rather than the content of the message.

    Take the evening news for example. Often these broadcasts begin with morbid subjects like the coverage of a murder or kidnapping. Then the broadcast will cover the weather, sports and a human-interest story. Viewers have an expectation of how this format will proceed because of the familiarity of the format.

    Content does not change much from broadcast to broadcast as the same types of stories are plugged into the recognizable format. Evening news broadcasts may be viewed while the family eats dinner and discusses the day’s proceedings. Engagement with the evening news serves as cultural currency for the consumer and the messages therein become conversation points to expand on in everyday conversations. Thus, communication content is shaped directly by the evening news ritual.

    Conclusion

    In closing, we have covered three types of models of communication to understand how interactions work and are affected by feedback and context. Our everyday interactions are shaped by a variety of factors that can alter the meaning or understanding of content. Often, the same message can be understood more effectively by changing the code or channel in which it is presented. By learning process models, we can more effectively encode and decode messaging to become more competent communicators.

    LEARNING ACTIVITIES

    Activity 1: Personal Model of Interpersonal Communication

    In small groups of 3-5 students, have them develop their own model of interpersonal communication. Include all of the components that are necessary to describe how communication between people works. The model could be a drawing or an object (such as a toaster or slinky toy) that symbolizes the communication process. Prepare to share the model with the class, explaining in detail about the model.

    Activity 2: Barriers to Communication

    In small groups of 3-5 students, assign each group a different communication context (i.e., verbal, written and/or online). Have them discuss within their group potential communication barriers for their context and ways to reduce those barriers. They should be prepared to discuss their answers with the class. During this discuss, the instructor should highlight common barriers that overlap the varied contexts for further discussion about the communication process (in general).

    Examples of different communication contexts that may be used in this activity include:

    · Verbal: interpersonal conversations with friends, family, co-workers, acquaintances and others; presentations in public settings; and communication business situations.

    · Written: writing a personal letter; text messaging with family, friends or others; and business writing such as a proposal, memo or presentation.

    · Online: emailing family or friends; using social media to connect with friends or others; communicating with others via instant messaging or video conferencing software.
