Linear Communication ModelInteractional Model of CommunicationBerlos Sender-Message-Channel-Receiver Model of CommunicationTransactional Model of CommunicationModels of communication refers to the conceptual model used to explain the humancommunication process. The first major model for communication came in 1949 by ClaudeElwood Shannon and Warren Weaver for Bell Laboratories[1] Following the basic concept,communication is the process of sending and receiving messages or transferring informationfrom one part (sender) to another (receiver).[2]

The senderwas the part of a telephone a person spoke into, the channel was the telephone itself, and thereceiver was the part of the phone where one could hear the other person. Shannon and Weaveralso recognized that often there is static that interferes with one listening to a telephoneconversation, which they deemed noise. The noise could also mean the absence of signal.[1]In a simple model, often referred to as the transmission model or standard view ofcommunication, information or content (e.g. a message in natural language) is sent in some form(as spoken language) from an emisor/ sender/ encoder to a destination/ receiver/ decoder. Thiscommon conception of communication views communication as a means of sending andreceiving information. The strengths of this model are simplicity, generality, and quantifiability.Social scientists Claude Shannon and Warren Weaver structured this model based on thefollowing elements: 1. An information source, which produces a message. 2. A transmitter, which encodes the message into signals 3. A channel, to which signals are adapted for transmission 4. A receiver, which decodes (reconstructs) the message from the signal. 5. A destination, where the message arrives.
  4. 4. Shannon and Weaver argued that there were three levels of problems for communication withinthis theory. The technical problem: how accurately can the message be transmitted? The semantic problem: how precisely is the meaning conveyed? The effectiveness problem: how effectively does the received meaning affect behavior?Daniel Chandler critiques the transmission model by stating:[3] It assumes communicators are isolated individuals. No allowance for differing purposes. No allowance for differing interpretations. No allowance for unequal power relations. No allowance for situational contexts.David BerloIn 1960, David Berlo expanded on Shannon and Weaver‘s (1949) linear model ofcommunication and created the SMCR Model of Communication.[4] The Sender-Message-Channel-Receiver Model of communication separated the model into clear parts and has beenexpanded upon by other scholars.SchrammCommunication is usually described along a few major dimensions: Message (what type ofthings are communicated), source / emisor / sender / encoder (by whom), form (in which form),channel (through which medium), destination / receiver / target / decoder (to whom), andReceiver. Wilbur Schramm (1954) also indicated that we should also examine the impact that amessage has (both desired and undesired) on the target of the message.[5] Between parties,communication includes acts that confer knowledge and experiences, give advice andcommands, and ask questions. These acts may take many forms, in one of the various manners ofcommunication. The form depends on the abilities of the group communicating. Together,communication content and form make messages that are sent towards a destination. The targetcan be oneself, another person or being, another entity (such as a corporation or group of beings).Communication can be seen as processes of information transmission governed by three levels ofsemiotic rules: 1. Syntactic (formal properties of signs and symbols), 2. Pragmatic (concerned with the relations between signs/expressions and their users) and 3. Semantic (study of relationships between signs and symbols and what they represent).Therefore, communication is social interaction where at least two interacting agents share acommon set of signs and a common set of semiotic rules. This commonly held rule in somesense ignores autocommunication, including intrapersonal communication via diaries or self-
  5. 5. talk, both secondary phenomena that followed the primary acquisition of communicativecompetences within social interactions.BarnlundIn light of these weaknesses, Barnlund (2008) proposed a transactional model ofcommunication.[6] The basic premise of the transactional model of communication is thatindividuals are simultaneously engaging in the sending and receiving of messages.In a slightly more complex form a sender and a receiver are linked reciprocally. This secondattitude of communication, referred to as the constitutive model or constructionist view, focuseson how an individual communicates as the determining factor of the way the message will beinterpreted. Communication is viewed as a conduit; a passage in which information travels fromone individual to another and this information becomes separate from the communication itself.A particular instance of communication is called a speech act. The senders personal filters andthe receivers personal filters may vary depending upon different regional traditions, cultures, orgender; which may alter the intended meaning of message contents. In the presence of"communication noise" on the transmission channel (air, in this case), reception and decoding ofcontent may be faulty, and thus the speech act may not achieve the desired effect. One problemwith this encode-transmit-receive-decode model is that the processes of encoding and decodingimply that the sender and receiver each possess something that functions as a codebook, and thatthese two code books are, at the very least, similar if not identical. Although something like codebooks is implied by the model, they are nowhere represented in the model, which creates manyconceptual difficulties.Theories of coregulation describe communication as a creative and dynamic continuous process,rather than a discrete exchange of information. Canadian media scholar Harold Innis had thetheory that people use different types of media to communicate and which one they choose to usewill offer different possibilities for the shape and durability of society (Wark, McKenzie 1997).His famous example of this is using ancient Egypt and looking at the ways they built themselvesout of media with very different properties stone and papyrus. Papyrus is what he called SpaceBinding. it made possible the transmission of written orders across space, empires and enablesthe waging of distant military campaigns and colonial administration. The other is stone andTime Binding, through the construction of temples and the pyramids can sustain their authoritygeneration to generation, through this media they can change and shape communication in theirsociety (Wark, McKenzie 1997).Psychology of communicationBernard Luskin, UCLA, 1970, advanced computer assisted instruction and began to connectmedia and psychology into what is now the field of media psychology. In 1998, the AmericanAssociation of Psychology, Media Psychology Division 46 Task Force report on psychology andnew technologies combined media and communication as pictures, graphics and soundincreasingly dominate modern communication.
  6. 6. Constructionist ModelThere is an additional working definition of communication to consider[examples needed] that authorslike Richard A. Lanham (2003) and as far back as Erving Goffman (1959) have highlighted. Thisis a progression from Lasswell‘s attempt to define human communication through to this centuryand revolutionized into the constructionist model. Constructionists believe that the process ofcommunication is in itself the only messages that exist. The packaging can not be separated fromthe social and historical context from which it arose, therefore the substance to look at incommunication theory is style for Richard Lanham and the performance of self for ErvingGoffman.Lanham chose to view communication as the rival to the over encompassing use of CBS model(which pursued to further the transmission model). CBS model argues that clarity, brevity, andsincerity are the only purpose to prose discourse, therefore communication. Lanham wrote, ―Ifwords matter too, if the whole range of human motive is seen as animating prose discourse, thenrhetoric analysis leads us to the essential questions about prose style‖ (Lanham 10). This issaying that rhetoric and style are fundamentally important; they are not errors to what weactually intend to transmit. The process which we construct and deconstruct meaning deservesanalysis.Erving Goffman sees the performance of self as the most important frame to understandcommunication. Goffman wrote, ―What does seem to be required of the individual is that helearn enough pieces of expression to be able to ‗fill in‘ and manage, more or less, any part that heis likely to be given‖ (Goffman 73) Goffman is highlighting the significance of expression.The truth in both cases is the articulation of the message and the package as one. Theconstruction of the message from social and historical context is the seed as is the pre-existingmessage is for the transmission model. Therefore any look into communication theory shouldinclude the possibilities drafted by such great scholars as Richard A. Lanham and ErvingGoffman that style and performance is the whole process.Communication stands so deeply rooted in human behaviors and the structures of society thatscholars have difficulty thinking of it while excluding social or behavioral events[weasel words].Because communication theory remains a relatively young field of inquiry and integrates itselfwith other disciplines such as philosophy, psychology, and sociology, one probably cannot yetexpect a consensus conceptualization of communication across disciplines[weasel words].Communication Model Terms as provided by Rothwell (11-15): Noise; interference with effective transmission and reception of a message. o For example;  physical noise or external noise which are environmental distractions such as poorly heated rooms, startling sounds, appearances of things, music playing some where else, and someone talking really loudly near you.  physiological noise are biological influences that distract you from communicating competently such as sweaty palms, pounding heart,
  7. 7. butterfly in the stomach, induced by speech anxiety, or feeling sick, exhausted at work, the ringing noise in your ear, being really hungry, and if you have a runny nose or a cough.  psychological noise are the preconception bias and assumptions such as thinking someone who speaks like a valley girl is dumb, or someone from a foreign country can‘t speak English well so you speak loudly and slowly to them.  semantic noise are word choices that are confusing and distracting such as using the word tri-syllabic instead of three syllables. Sender; the initiator and encoder of a message Receiver; the one that receives the message (the listener) and the decoder of a message Decode; translates the senders spoken idea/message into something the receiver understands by using their knowledge of language from personal experience. Encode; puts the idea into spoken language while putting their own meaning into the word/message. Channel; the medium through which the message travels such as through oral communication (radio, television, phone, in person) or written communication (letters, email, text messages) Feedback; the receivers verbal and nonverbal responses to a message such as a nod for understanding (nonverbal), a raised eyebrow for being confused (nonverbal), or asking a question to clarify the message (verbal). Message; the verbal and nonverbal components of language that is sent to the receiver by the sender which conveys an idea.Linear ModelIt is a one way model to communicate with others. It consists of the sender encoding a messageand channeling it to the receiver in the presence of noise. Draw backs – the linear model assumesthat there is a clear cut beginning and end to communication. It also displays no feedback fromthe receiver. For example; a letter, email, text message, lecture.The Linear Model.Interactive Model
  8. 8. It is two linear models stacked on top of each other. The sender channels a message to thereceiver and the receiver then becomes the sender and channels a message to the original sender.This model has added feedback, indicates that communication is not a one way but a two wayprocess. It also has ―field of experience‖ which includes our cultural background, ethnicitygeographic location, extend of travel, and general personal experiences accumulated over thecourse of your lifetime. Draw backs – there is feedback but it is not simultaneous.The Interactive Model. For example – instant messaging. The sender sends an IM to the receiver, then the original sender has to wait for the IM from the original receiver to react. Or a question/answer session where you just ask a question then you get an answer.Transactional ModelIt assumes that people are connected through communication; they engage in transaction. Firstly,it recognizes that each of us is a sender-receiver, not merely a sender or a receiver. Secondly, itrecognizes that communication affects all parties involved. So communication isfluid/simultaneous. This is how most conversations are like. The transactional model alsocontains ellipses that symbolize the communication environment (how you interpret the data thatyou are given). Where the ellipses meet is the most effective communication area because bothcommunicators share the same meaning of the message. For example – talking/listening to friends. While your friend is talking you are constantly giving them feedback on what you think through your facial expression verbal feedback without necessarily stopping your friend from talking.The Transactional Model.
  9. 9. Communication Theory FrameworkMain article: Theory of communicationIt is helpful to examine communication and communication theory through one of the followingviewpoints[weasel words]: Mechanistic: This view[who?] considers communication as a perfect transaction of a message from the sender to the receiver. (as seen in the diagram above) Psychological: This view[who?] considers communication as the act of sending a message to a receiver, and the feelings and thoughts of the receiver upon interpreting the message. Social Constructionist (Symbolic Interactionist): This view} considers communication to be the product of the interactants sharing and creating meaning. The Constructionist View can also be defined as, how you say something determines what the message is. The Constructionist View assumes that ―truth‖ and ―ideas‖ are constructed or invented through the social process of communication. Robert T. Craig saw the Constructionist View or the constitutive view as it‘s called in his article, as ―…an ongoing process that symbolically forms and re-forms our personal identities.‖ (Craig, 125). The other view of communication, the Transmission Model, sees communication as robotic and computer- like. The Transmission Model sees communication as a way of sending or receiving messages and the perfection of that. But, the Constructionist View sees communications as, ―…in human life, info does not behave as simply as bits in an electronic stream. In human life, information flow is far more like an electric current running from one landmine to another‖ (Lanham, 7). The Constructionist View is a more realistic view of communication[opinion] because it involves the interacting of human beings and the free sharing of thoughts and ideas. Daniel Chandler looks to prove that the Transmission Model is a lesser way of communicating by saying ―The transmission model is not merely a gross over-simplification but a dangerously misleading representation of the nature of human communication‖ (Chandler, 2). Humans do not communicate simply as computers or robots so that‘s why it‘s essential to truly understand the Constructionist View of Communication well. We do not simply send facts and data to one another, but we take facts and data and they acquire meaning through the process of communication, or through interaction with others. Systemic: This view[who?] considers communication to be the new messages created via ―through-put‖, or what happens as the message is being interpreted and re-interpreted as it travels through people. Critical: This view considers communication as a source of power and oppression of individuals and social groups.[7]Inspection of a particular theory on this level will provide a framework on the nature ofcommunication as seen within the confines of that theory.Theories can also be studied and organized according to the ontological, epistemological, andaxiological framework imposed by the theorist.
  10. 10. OntologyOntology essentially poses the question of what, exactly, it is the theorist is examining. One mustconsider the very nature of reality. The answer usually falls in one of three realms depending onwhether the theorist sees the phenomena through the lens of a realist, nominalist, or socialconstructionist. Realist perspective views the world objectively, believing that there is a worldoutside of our own experience and cognitions. Nominalists see the world subjectively, claimingthat everything outside of one‘s cognitions is simply names and labels. Social constructionistsstraddle the fence between objective and subjective reality, claiming that reality is what wecreate together.[unbalanced opinion][neutrality is disputed]EpistemologyEpistemology is an examination of how the theorist studies the chosen phenomena. In studyingepistemology, particularly from a positivist perspective, objective knowledge is said[who?] to bethe result of a systematic look at the causal relationships of phenomena. This knowledge isusually attained through use of the scientific method[neutrality is disputed]. Scholars oftenthink[weasel words] that empirical evidence collected in an objective manner is most likely to reflecttruth in the findings. Theories of this ilk are usually created to predict a phenomenon. Subjectivetheory holds that understanding is based on situated knowledge, typically found usinginterpretative methodology such as ethnography and also interviews. Subjective theories aretypically developed to explain or understand phenomena in the social world.[citation needed]AxiologyAxiology is concerned with how values inform research and theory development.[8] Mostcommunication theory is guided by one of three axiological approaches. The first approachrecognizes that values will influence theorists interests but suggests that those values must be setaside once actual research begins. Outside replication of research findings is particularlyimportant in this approach to prevent individual researchers values from contaminating theirfindings and interpretations.[9] The second approach rejects the idea that values can be eliminatedfrom any stage of theory development. Within this approach, theorists do not try to divorce theirvalues from inquiry. Instead, they remain mindful of their values so that they understand howthose values contextualize, influence or skew their findings.[10] The third approach not onlyrejects the idea that values can be separated from research and theory, but rejects the idea thatthey should be separated. This approach is often adopted by critical theorists who believe that therole of communication theory is to identify oppression and produce social change. In thisaxiological approach, theorists embrace their values and work to reproduce those values in theirresearch and theory development.[11]Mapping the theoretical landscapeA discipline gets defined in large part by its theoretical structure[weasel words]. Communicationstudies often borrow theories from other social sciences[neutrality is disputed]. This theoretical variation
  11. 11. makes it difficult to come to terms with the field as a whole[neutrality is disputed]. That said, somecommon taxonomies exist that serve to divide up the range of communication research. Twocommon mappings involve contexts and assumptions.ContextsMany authors and researchers[who?] divide communication by what they sometimes called"contexts" or "levels", but which more often represent institutional histories[neutrality is disputed].The study of communication in the US, while occurring within departments of psychology,sociology, linguistics, and anthropology (among others), generally developed from schools ofrhetoric and from schools of journalism. While many of these have become "departments ofcommunication", they often retain their historical roots, adhering largely to theories from speechcommunication in the former case, and from mass media in the latter. The great divide betweenspeech communication and mass communication becomes complicated by a number of smallersub-areas of communication research, including intercultural and international communication,small group communication, communication technology, policy and legal studies ofcommunication, telecommunication, and work done under a variety of other labels. Some ofthese departments take a largely social-scientific perspective, others tend more heavily towardthe humanities, and still others gear themselves more toward production and professionalpreparation.These "levels" of communication provide some way of grouping communication theories, butinevitably, some theories and concepts leak from one area to another, or fail to find a home at all.The Constitutive MetamodelMain article: Communication Theory as a FieldAnother way of dividing up the communication field emphasizes the assumptions that undergirdparticular theories, models, and approaches. Robert T. Craig suggests that the field ofcommunication as a whole can be understood as several different traditions who have a specificview on communication. By showing the similarities and differences between these traditions,Craig argues that the different traditions will be able to engage each other in dialogue rather thanignore each other.[12] Craig proposes seven different traditions which are: 1. Rhetorical: views communication as the practical art of discourse.[13] 2. Semiotic: views communication as the mediation by signs.[14] 3. Phenomenological: communication is the experience of dialogue with others.[15] 4. Cybernetic: communication is the flow of information.[16] 5. Socio-psychological: communication is the interaction of individuals.[17] 6. Socio-cultural: communication is the production and reproduction of the social order.[18] 7. Critical: communication is the process in which all assumptions can be challenged.[19]Craig finds each of these clearly defined against the others, and remaining cohesive approachesto describing communicative behavior. As a taxonomic aid, these labels help to organize theory
  12. 12. by its assumptions, and help researchers to understand why some theories may seemincommensurable.While communication theorists very commonly use these two approaches, theorists decentralizethe place of language and machines as communicative technologies. The idea (as argued byVygotsky) of communication as the primary tool of a species defined by its tools remains on theoutskirts of communication theory. It finds some representation in the Toronto School ofcommunication theory (alternatively sometimes called medium theory) as represented by thework of Innis, McLuhan, and others. It seems that the ways in which individuals and groups usethe technologies of communication — and in some cases are used by them — remain central towhat communication researchers do. The ideas that surround this, and in particular the place ofpersuasion, remain constants across both the "traditions" and "levels" of communication theory.Some realms of communication and their theories universal communication Law: Universal Theory, Dynamic-transactional Ansatz message production: Constructivist Theory, Action Assembly Theory message processing: Elaboration Likelihood Model, Inoculation theory discourse and interaction: Speech Acts Theory, Coordinated Management of Meaning developing relationships: Uncertainty Reduction Theory, Social Penetration Theory, Predicted Outcome Value Theory ongoing relationships: Relational Systems Theory, Relational Dialectics organizational: Structuration Theory, Unobtrusive and Concertive Control Theory small group: Functional Theory, Symbolic Convergence Theory media processing and effects: Social Cognitive Theory, Uses and Gratifications Theory media and society: Agenda Setting, Information deficit model, Spiral of silence, Symbolic Convergence Theory culture: Speech Codes Theory, Face-saving Theory making social worlds: Coordinated Management of Meaning, Symbolic InteractionismReferences 1. ^ a b Shannon, C.
