1.6 Circular Communication Model

The Circular Communication Model describes communication as a continuous, bidirectional, and mutually constitutive process in which participants are simultaneously and continuously both senders and receivers, with no fixed starting point, no definitive endpoint, and no clean separation between message production and response. This model emerged as a direct correction of linear transmission models, which depicted communication as a one-way sequence from sender to receiver.

The Problem with Linear Models

Linear models such as Shannon and Weaver's 1949 model depicted communication as a unidirectional sequence:

Source → Encoder → Channel → Decoder → Receiver

This representation, while analytically useful for engineering purposes, fundamentally distorts the nature of human communication in several ways:

• It implies that communication begins with a sender who has a pre-formed message and ends when a receiver decodes it.
• It assigns distinct, non-overlapping roles: one party sends, the other receives.
• It treats the receiver as a passive endpoint rather than an active co-participant.
• It excludes the ongoing mutual influence that shapes communication as it unfolds.

Harold Lasswell's corresponding verbal model—"Who says what in which channel to whom with what effect?"—shares these linearizing assumptions. Real human communication rarely corresponds to this sequence.

The Circular Structure

The circular model addresses these limitations by proposing that:

1. Both parties are simultaneously senders and receivers. While one person speaks, the other is producing a constant stream of nonverbal and paralinguistic signals—nodding, frowning, leaning forward, shifting posture—that function as simultaneous messages, influencing the speaker's ongoing production.

2. Communication has no fixed beginning or end. Any given exchange is embedded in a prior history of interactions that shape the meaning of current messages, and in an anticipated future that gives current messages their strategic significance.

3. Responses modify subsequent messages. The circular model incorporates feedback as a continuous process of mutual adjustment rather than a post-hoc evaluation. The speaker shapes their message in real time based on the receiver's ongoing responses.

4. Meaning is coconstructed. Neither party alone controls the meaning of the exchange; meaning emerges from the interaction between the messages produced, the interpretive frameworks applied by both parties, and the relational and cultural contexts in which the exchange is embedded.

Schramm's Circular Model

Wilbur Schramm's revision of Shannon and Weaver's model introduced the concept of a "field of experience" that both communicators bring to the exchange. For communication to succeed, the fields of experience must overlap: messages that fall entirely outside the receiver's experience cannot be decoded.

Schramm extended the model further by replacing the linear sequence with a circular one in which both parties simultaneously encode and decode, producing and interpreting messages in a continuous loop. The model represented each communicator as performing both the encoder/interpreter functions, connected by a bidirectional feedback loop through the shared field of experience.

Osgood-Schramm and the Symmetry of Communication

The Osgood-Schramm model, developed collaboratively with Charles Osgood, presented the most explicit circular structure: each communicator performs three processes—encoding, decoding, and interpreting—and these processes are identical in both parties. The model has no labeled "sender" or "receiver" because both parties always occupy both roles. Communication is represented as a circle in which messages flow continuously between two encoding-decoding-interpreting nodes.

This symmetry makes explicit a principle that linear models obscure: listening is not passive waiting but active interpretive work, and responding is not a mere reaction but a new encoding of the interpreted message plus the respondent's own perspective and goals.

Circular Causality

The circular model embodies the cybernetic principle of circular causality: A causes B, B causes A, in an ongoing loop with no identifiable first cause. In communication:

• A speaker's hesitation causes a listener's attention to intensify.
• Intensified attention causes the speaker to feel more confident.
• Increased confidence causes the speaker to elaborate.
• The elaboration causes the listener to generate a question.
• The question reshapes the speaker's subsequent framing.

Each response is simultaneously an effect of the preceding message and a cause of the subsequent one. This mutual determination makes it meaningless to ask "who started it" or to assign exclusive causal responsibility to one party.

Punctuation

Paul Watzlawick, Janet Beavin Bavelas, and Don Jackson identified punctuation as the process by which communicators impose a starting point and causal structure on the continuous flow of circular communication. Because interaction is an unbroken sequence, participants must choose where to begin their analysis—and they typically choose a starting point that portrays their own behavior as a response to the other rather than a cause of the other's behavior.

A classic example: one partner says "I nag because you withdraw"; the other says "I withdraw because you nag." Each party punctuates the circular sequence differently, identifying the other's behavior as the first cause. Both punctuations are simultaneously valid descriptions of the same circular pattern. Conflicts about punctuation—about who "started" a pattern or who is "to blame"—are among the most common and most refractory communication problems in close relationships.

The Transactional Model as Extension

Dean Barnlund's transactional model extends the circular approach further by emphasizing that:

• Communication is simultaneous, not sequential: both parties are always communicating at the same time on multiple channels.
• Messages include not only intentional verbal content but all behavior and signals—including silence and absence—that occur in the communicative context.
• Communicators bring prior experiences, attitudes, values, and cultural frameworks to every exchange, and these shape both what is sent and what is interpreted.
• The environment—physical setting, temporal context, social structure—is itself a message that shapes what can be communicated and how.

Implications for Communication Competence

The circular model has practical implications for how communication competence is understood and taught:

• Listening is not a passive gap between turns but an active and continuously communicative act that shapes the direction and quality of the exchange.
• Effective communicators monitor their impact on others in real time and adjust their communication based on the responses they observe.
• Responsibility for communication outcomes is shared: the meaning of a message is not determined by the sender's intention alone but by the interactive process through which it is produced, transmitted, received, and responded to.
• Communication breakdown cannot be attributed to a single failure in a linear sequence but must be analyzed as a property of the circular pattern within which it occurs.

The Circular Communication Model thus provides a more accurate and more empowering account of communication than its linear predecessors—one that acknowledges the mutual, recursive, and contextually embedded character of all communicative exchange.
