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.

to mass communication.
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.
