Transaction Model of Communication

As the study of communication progressed, models expanded to account for more of the communication process. Many scholars view communication as more than a process that is used to carry on conversations and convey meaning. We don’t send messages like computers, and we don’t neatly alternate between the roles of sender and receiver as an interaction unfolds. We also can’t consciously decide to stop communicating, because communication is more than sending and receiving messages. The transaction model differs from the transmission and interaction models in significant ways, including the conceptualization of communication, the role of sender and receiver, and the role of context. Dean C. Barnlund, “A Transactional Model of Communication,” in Foundations of Communication Theory, eds. Kenneth K. Sereno and C. David Mortensen (New York, NY: Harper and Row, 1970), 83–92.

To review, each model incorporates a different understanding of what communication is and what communication does. The transmission model views communication as a thing, like an information packet, that is sent from one place to another. From this view, communication is defined as sending and receiving messages. The interaction model views communication as an interaction in which a message is sent and then followed by a reaction (feedback), which is then followed by another reaction, and so on. From this view, communication is defined as producing conversations and interactions within physical and psychological contexts. The transaction model views communication as integrated into our social realities in such a way that it helps us not only understand them but also create and change them.

The transaction model of communication describes communication as a process in which communicators generate social realities within social, relational, and cultural contexts. In this model, we don’t just communicate to exchange messages; we communicate to create relationships, form intercultural alliances, shape our self-concepts, and engage with others in dialogue to create communities. In short, we don’t communicate about our realities; communication helps to construct our realities.

The roles of sender and receiver in the transaction model of communication differ significantly from the other models. Instead of labeling participants as senders and receivers, the people in a communication encounter are referred to as communicators. Unlike the interaction model, which suggests that participants alternate positions as sender and receiver, the transaction model suggests that we are simultaneously senders and receivers. For example, on a first date, as you send verbal messages about your interests and background, your date reacts nonverbally. You don’t wait until you are done sending your verbal message to start receiving and decoding the nonverbal messages of your date. Instead, you are simultaneously sending your verbal message and receiving your date’s nonverbal messages. This is an important addition to the model because it allows us to understand how we are able to adapt our communication—for example, a verbal message—in the middle of sending it based on the communication we are simultaneously receiving from our communication partner.

The transaction model also includes a more complex understanding of context. The interaction model portrays context as physical and psychological influences that enhance or impede communication. While these contexts are important, they focus on message transmission and reception. Since the transaction model of communication views communication as a force that shapes our realities before and after specific interactions occur, it must account for contextual influences outside of a single interaction. To do this, the transaction model considers how social, relational, and cultural contexts frame and influence our communication encounters.

Social context refers to the stated rules or unstated norms that guide communication. As we are socialized into our various communities, we learn rules and implicitly pick up on norms for communicating. Some common rules that influence social contexts include don’t lie to people, don’t interrupt people, don’t pass people in line, greet people when they greet you, thank people when they pay you a compliment, and so on. Parents and teachers often explicitly convey these rules to their children or students. Rules may be stated over and over, and there may be punishment for not following them.

Norms are social conventions that we pick up on through observation, practice, and trial and error. We may not even know we are breaking a social norm until we notice people looking at us strangely or someone corrects or teases us. For example, as a new employee you may over- or underdress for the company’s holiday party because you don’t know the norm for formality. Although there probably isn’t a stated rule about how to dress at the holiday party, you will notice your error without someone having to point it out, and you will likely not deviate from the norm again in order to save yourself any potential embarrassment. Even though breaking social norms doesn’t result in the formal punishment that might be a consequence of breaking a social rule, the social awkwardness we feel when we violate social norms is usually enough to teach us that these norms are powerful even though they aren’t made explicit like rules. Norms even have the power to override social rules in some situations. To go back to the examples of common social rules mentioned before, we may break the rule about not lying if the lie is meant to save someone from feeling hurt. We often interrupt close friends when we’re having an exciting conversation, but we wouldn’t be as likely to interrupt a professor while they are lecturing. Since norms and rules vary among people and cultures, relational and cultural contexts are also included in the transaction model in order to help us understand the multiple contexts that influence our communication.

Relational context includes the previous interpersonal history and type of relationship we have with a person. We communicate differently with someone we just met versus someone we’ve known for a long time. Initial interactions with people tend to be more highly scripted and governed by established norms and rules, but when we have an established relational context, we may be able to bend or break social norms and rules more easily. For example, you would likely follow social norms of politeness and attentiveness and might spend the whole day cleaning the house for the first time you invite your new neighbors to visit. Once the neighbors are in your house, you may also make them the center of your attention during their visit. If you end up becoming friends with your neighbors and establishing a relational context, you might not think as much about having everything cleaned and prepared or even giving them your whole attention during later visits. Since communication norms and rules also vary based on the type of relationship people have, relationship type is also included in relational context. For example, there are certain communication rules and norms that apply to a supervisor-supervisee relationship that don’t apply to a brother-sister relationship and vice versa. Just as social norms and relational history influence how we communicate, so does culture.

Cultural context includes various aspects of identities such as race, gender, nationality, ethnicity, sexual orientation, class, and ability. We will learn more about these identities in Chapter 2 "Communication and Perception", but for now it is important for us to understand that whether we are aware of it or not, we all have multiple cultural identities that influence our communication. Some people, especially those with identities that have been historically marginalized, are regularly aware of how their cultural identities influence their communication and influence how others communicate with them. Conversely, people with identities that are dominant or in the majority may rarely, if ever, think about the role their cultural identities play in their communication.

When cultural context comes to the forefront of a communication encounter, it can be difficult to manage. Since intercultural communication creates uncertainty, it can deter people from communicating across cultures or lead people to view intercultural communication as negative. But if you avoid communicating across cultural identities, you will likely not get more comfortable or competent as a communicator. Difference, as we will learn in Chapter, isn’t a bad thing. In fact, intercultural communication has the potential to enrich various aspects of our lives. In order to communicate well within various cultural contexts, it is important to keep an open mind and avoid making assumptions about others’ cultural identities. While you may be able to identify some aspects of the cultural context within a communication encounter, there may also be cultural influences that you can’t see. A competent communicator shouldn’t assume to know all the cultural contexts a person brings to an encounter, since not all cultural identities are visible. As with the other contexts, it requires skill to adapt to shifting contexts, and the best way to develop these skills is through practice and reflection.


  • Communication models are not complex enough to truly capture all that takes place in a communication encounter, but they can help us examine the various steps in the process in order to better understand our communication and the communication of others.
  • The transmission model of communication describes communication as a one-way, linear process in which a sender encodes a message and transmits it through a channel to a receiver who decodes it. The transmission of the message many be disrupted by environmental or semantic noise. This model is usually too simple to capture FtF interactions but can be usefully applied to computer-mediated communication.
  • The interaction model of communication describes communication as a two-way process in which participants alternate positions as sender and receiver and generate meaning by sending and receiving feedback within physical and psychological contexts. This model captures the interactive aspects of communication but still doesn’t account for how communication constructs our realities and is influenced by social and cultural contexts.
  • The transaction model of communication describes communication as a process in which communicators generate social realities within social, relational, and cultural contexts. This model includes participants who are simultaneously senders and receivers and accounts for how communication constructs our realities, relationships, and communities.


  1. Getting integrated: How might knowing the various components of the communication process help you in your academic life, your professional life, and your civic life?
  2. What communication situations does the transmission model best represent? The interaction model? The transaction model?
  3. Use the transaction model of communication to analyze a recent communication encounter you had. Sketch out the communication encounter and make sure to label each part of the model (communicators; message; channel; feedback; and physical, psychological, social, relational, and cultural contexts).
