01 Foundations of Communication
Learn how people create and interpret meaning through messages, how communication models describe that process, and how context and communication settings shape everyday interactions.
creates meaning
is the process through which people use messages to create and interpret meaning. Messages can be verbal, such as spoken or written words, or nonverbal, such as facial expressions, gestures, timing, and tone. is more than transferring information: meaning depends on how people interpret messages and the circumstances in which they encounter them.
People communicate to share information, coordinate tasks, express feelings, build relationships, negotiate expectations, and participate in community life. Asking a colleague to revise a report conveys a task while also helping define workplace roles and expectations. Messages can be ambiguous: “Could you look at this?” might mean a careful review or a casual glance. A speaker’s intention matters, but so does the listener’s interpretation; questions and responses can help clarify meaning.
Three models of
Models simplify so its features are easier to examine. The , , and emphasize different aspects of the process. They are complementary tools rather than competing rules.
: A source encodes a message and sends it through a channel to a receiver, who decodes it. —anything that interferes with the message—may disrupt this process. A public announcement may be difficult to understand because of poor audio or unfamiliar terms. This model is useful for one-way messages but gives little attention to .
: Communicators take turns sending messages and responding. lets a speaker adjust or clarify. In a text exchange, one person might send a question, wait for a reply, and then respond.
: People send and interpret messages at the same time, using verbal and nonverbal cues. is shaped by the relationship and situation, and can help shape them in turn. A listener’s expression may prompt a speaker to explain an idea differently. This model highlights as a dynamic, shared process.
A recorded announcement may be mostly linear, while a face-to-face conversation is often better understood transactionally.
and settings
means the circumstances that influence how messages are produced and understood. It includes the physical setting, purpose, participants’ relationships, social expectations, cultural knowledge, and channel. A brief message may seem clear to close friends who share background knowledge but confusing to a new colleague. The same words can carry different implications in a private conversation and a public meeting.
settings often overlap:
Interpersonal : Exchanges between people who influence one another, such as friends, family members, classmates, or coworkers. These interactions help people share information, manage relationships, and resolve misunderstandings.
Group : among people coordinating around a shared purpose, such as a project team or community committee. Members share information, make decisions, and negotiate roles.
Organizational : within and between organizations. Meetings, policies, emails, informal conversations, and public statements help coordinate work and shape an organization’s culture.
Public : One person or a small group addresses an audience, as in a speech, presentation, or public meeting. Speakers adapt messages to their purpose, audience, and occasion; audience responses can provide .
: carried through a medium or technology, such as a phone call, email, video meeting, or social platform. The medium affects which cues are available, how quickly people can respond, and who may encounter a message.
A team meeting is both group and organizational . A presentation shared online is both public and .
in everyday life
Everyday involves choices about what to say, how to express it, when to speak, and which channel to use. Listening is part of this process: attending to another person’s message and checking one’s understanding can prevent avoidable confusion. , such as a question, paraphrase, or facial expression, helps communicators see how a message is being received. may come from outside, such as traffic, or from within, such as distraction or worry.
is symbolic and cultural. Words and gestures do not carry exactly the same meaning for everyone; people interpret them through shared conventions and personal experience. When expectations differ, asking for clarification is often more reliable than assuming intent. can maintain relationships and accomplish practical tasks, and it can also reinforce or change social expectations. Attention to and effects supports more thoughtful participation in private, professional, and civic life.
