How communication scholars define communication itself, why it matters, and the core models,
principles, and ethical foundations that everything else in this course builds on.
Why Study Communication
Communication is one of the most practical, transferable skills a person can build. Employers
consistently rank communication skills—speaking, writing, listening—among the top qualities
they look for in new hires, often above technical expertise. Beyond the job market, communication is how
we build relationships, participate in civic life, and understand ourselves.
Four broad reasons make communication worth studying seriously:
Career success. Nearly every profession requires communicating with
colleagues, clients, and supervisors—in meetings, presentations, emails, and one-on-one
conversations.
Personal relationships. The quality of our friendships, family
relationships, and romantic partnerships depends heavily on how well we communicate.
Civic and democratic life. Talking through disagreements, deliberating in
groups, and participating in public discourse all rely on communication competence.
Self-understanding. We come to understand our own identity, values, and
beliefs partly through the process of articulating them to others.
Defining Human Communication
At its simplest, communication is the process of generating meaning by sending
and receiving symbolic cues that are influenced by multiple contexts. Every phrase in that definition
matters:
Key Term
Communication — the process of
generating meaning through the sending and receiving of symbolic cues that are affected by multiple
contexts.
Process. Communication is ongoing and dynamic, not a single, isolated
event. It unfolds over time and has no clear beginning or end.
Generating meaning. Communication is about making sense of the world and
sharing that sense with others—meaning is created, not just transmitted.
Symbolic cues. Words, gestures, images, and sounds are symbols—they
represent ideas but are not the ideas themselves. Symbols are arbitrary (there is no natural
connection between the word "tree" and an actual tree), ambiguous (they can be interpreted in more
than one way), and abstract (they stand in for something that is not physically present).
Multiple contexts. Communication is shaped by the context in which it
occurs, including psychological, relational, situational, environmental, and cultural context.
Types of Contexts
Context
What It Refers To
Psychological
The moods, emotions, and attitudes each communicator brings to the interaction.
Relational
The existing relationship between the communicators and how it shapes their interaction.
Situational
The specific event or circumstance in which communication takes place (e.g., a job interview vs.
a casual chat).
Environmental
The physical surroundings—location, layout, temperature, noise—that affect an
interaction.
Cultural
The beliefs, values, attitudes, and ways of communicating shared by a group and passed down over
time.
Models of Communication
Scholars have historically represented the communication process with three progressively more
sophisticated models.
The Linear Model
The earliest model treats communication as a one-way, linear process: a sender
encodes a message and transmits it through a channel to a receiver, who decodes it. Noise—anything that
interferes with the message—can occur at any point. This model is useful for illustrating basic
components, but it treats communication as one-directional, which does not reflect how real
conversations work.
The Interactive Model
The interactive model improves on the linear model by adding feedback—the receiver's response, which turns the sender into a receiver
and vice versa. This model also introduces the idea of a field of experience:
the influence of a person's culture, experience, and background on the communication process.
The Transactional Model
The transactional model is the most complete: it depicts communication as a
simultaneous, ongoing process in which both people are senders and receivers at the same time,
continuously constructing shared meaning together, all within overlapping fields of experience and
multiple contexts.
Example
While you are talking to a friend, you are simultaneously watching
their facial expression and adjusting your tone based on their reaction—you are not waiting for
them to finish before you start "receiving." That simultaneity is what the transactional model captures
that the linear model misses.
Principles of Communication
Communication can be intentional or unintentional. We often communicate
messages we did not consciously plan to send (e.g., an unintentional sigh signaling frustration).
It is impossible not to communicate. Even silence or the absence of a
response sends a message.
Communication is irreversible. Once a message is sent, it cannot be
"unsent"—you can apologize or clarify, but you cannot erase the fact that it was communicated.
Communication is not a panacea. More communication is not always better;
sometimes it can escalate a conflict rather than resolve it.
Communication Competence
Communication competence is the impression that communication behavior is both
appropriate and effective in a given situation.
Key Term
Appropriateness — communication
that fits the expectations of a given context or culture.
Key Term
Effectiveness — communication that
achieves its intended goal.
Competent communicators are able to adapt their behavior depending on the context and the people
involved—what is appropriate and effective with close friends is often not appropriate or
effective with a professor or a manager. Communication competence also requires cognitive complexity (the capacity to construct a variety of frameworks for
viewing an issue) and self-monitoring (the capacity to observe your own
communication behavior and adjust it).
Communication and Ethics
Ethics refers to the perceived rightness or wrongness of an action or
behavior. Because communication always has consequences for others, ethical considerations run through
nearly every communication choice—from what we choose to disclose, to how honestly we represent
facts, to how we treat people whose views differ from our own.
Study Tip
Ethical communication is a recurring thread across this entire
course—you will see it return in the chapters on interpersonal relationships (honesty,
self-disclosure) and inclusive communication (respect, avoiding bias). It is worth treating as a
throughline rather than a one-time topic.
Chapter Summary
Communication skills are valued in career, relational, civic, and personal-development contexts.
Communication is the process of generating meaning through symbolic cues shaped by multiple contexts
(psychological, relational, situational, environmental, cultural).
Three models describe the communication process with increasing sophistication: linear, interactive,
and transactional.
Core principles: communication can be unintentional, it is impossible not to communicate, it is
irreversible, and it is not a cure-all.
Communication competence means being both appropriate and effective, and requires cognitive
complexity and self-monitoring.
Ethics—the rightness or wrongness of communication choices—underlies the whole study of
communication.
