How groups develop their own culture and norms, what separates effective leadership from ineffective leadership, and a systematic process for group problem solving and decision-making.
Small groups are the basic building blocks of society—families, work teams, support groups, religious circles, and study groups are all examples. Learning to communicate effectively in groups matters for four reasons: groups fulfill William Schutz's needs for inclusion, affection, and control (see Chapter 6); group work is the norm in business and industry, so group skills are highly valued by employers; being an effective group member is a learnable, masterable skill, not an innate talent; and participating in small groups builds confidence in articulating beliefs, which strengthens civic and democratic participation.
This definition implies: the group must be small enough that members are mutually aware they form a collective entity (research shows groups of three or four are often more productive than groups of five or more); the interaction itself is what holds the group together; and members are interdependent—they cannot achieve their shared goal without each other.
| Classification | Definition | Example |
|---|---|---|
| Assigned group | Individuals are appointed to be members. | A student union advisory board. |
| Emergent group | Individuals choose to form the group out of personal need or desire. | A friend group that meets at college. |
| Task-oriented group | Formed to complete a task, such as solving a problem or making a decision. | Students studying together for an exam. |
| Relationship-oriented group | Usually long-term; exists to meet needs for inclusion and affection. | A family. |
These categories often blur in practice—an assigned, task-oriented class group can develop strong relational bonds over time, and a relationship-oriented group like a family still has to complete tasks together.
Norms often develop rapidly and implicitly—without anyone consciously "deciding" on a rule. If a member arrives late to a meeting and no one objects, the group has implicitly signaled that punctuality is not strictly enforced. Groups reinforce norms through feedback, such as a leader reminding members to put devices away.
A role is a consistent pattern of interaction or behavior a member exhibits over time. Roles can be formal (an assigned or positional role, such as treasurer or note-taker) or informal (a behavioral role that develops naturally based on personality and interaction, such as the group member who naturally becomes the facilitator).
| Function Type | Purpose | Example Behaviors |
|---|---|---|
| Task functions | Directly relevant to the group's purpose; affect productivity. | Initiating, information giving/seeking, opinion giving, clarifying, summarizing, coordinating. |
| Maintenance functions | Support cooperative, harmonious relationships among members. | Gatekeeping, supporting, harmonizing, relieving tension, showing solidarity. |
| Self-centered functions | Serve an individual's needs at the group's expense. | Withdrawing, blocking, seeking status/recognition. |
Both task and maintenance functions are essential to effective group communication; self-centered functions, by contrast, use the group to serve personal goals that compete with the group's own.
A group's climate—its emotional tone—is shaped by three factors: trust (task trust and interpersonal trust that others are working toward the group's goals, not hidden agendas), supportiveness (openness in which members care about each other, echoing Gibb's supportive categories from Chapter 6), and cohesiveness (the attachment members feel toward each other and the group). Highly cohesive groups tend to be more open, handle disagreement more effectively, and typically perform better.
Observable warning signs of groupthink include an illusion of invulnerability, an unquestioned belief in the group's morality, rationalizing away faulty decisions, stereotyping opposing viewpoints as weak or evil, self-censorship of dissenting opinions, direct pressure on members who express disagreement, and the emergence of "mind guards" who screen out contradictory information.
Within-group diversity can be observable (visible differences such as able-bodiedness, perceived gender, or age) or implicit (unseen differences such as values, political beliefs, or educational background). Group polarization around identity differences can create "in-group" and "out-group" conflict; the common in-group identity model suggests finding and emphasizing what members have in common rather than focusing on differences.
Group leaders must attend to four issues: identifying the group's task, creating cohesiveness, monitoring and adapting member behavior, and keeping the group focused. Leadership is the process of using communication to influence the behaviors and attitudes of others to meet group goals.
| Power Type | Description |
|---|---|
| Reward power | The ability to give followers what they want or need. |
| Punishment power | The ability to withhold what followers want or need, including coercion. |
| Referent power | Power based on others' admiration and respect (e.g., charisma). |
| Expert power | Power that arises from others valuing a person's knowledge or expertise. |
| Legitimate power | Power granted because of an official title, position, or role—most often used by designated leaders. |
Most people in the U.S. report greater satisfaction in democratically led groups, but the "best" style depends on the situation—an urgent deadline may call for a more directive approach than a democratic one would allow.
Effective leaders know the task at hand, know the people in the group, collect information in advance, distribute leadership when appropriate, and organize the discussion using a clear agenda (approval of past minutes, announcements, reports, new business, old business).
Groups are usually (though not always) better problem solvers than individuals because they combine more information and broader perspectives—but only when the process is systematic and organized.
| Question Type | Asks | Example |
|---|---|---|
| Questions of fact | Whether something is true or can be verified. | "How many first-generation students are enrolled?" |
| Questions of value | Whether something is good/bad, better/worse. | "Does our legal system provide justice for all?" |
| Questions of policy | What action should be taken (the word "should" is stated or implied). | "Should the state's drunk-driving laws be changed?" |
Effective groups start with a problem question ("How can we reduce parking complaints?") rather than a solution question ("How can we increase parking spaces?"), because solution questions bias the group toward one option before alternatives are considered.
Criteria are the standards used to judge potential solutions. Absolute criteria must be met (no leeway); important criteria should be met but allow flexibility. Solutions that fail absolute criteria are rejected outright; remaining options are ranked by how well they satisfy important criteria.
Brainstorming works best when members defer all judgment—positive or negative—until every idea has been generated ("no evaluation" is the core rule), because critical evaluation during idea generation kills creativity. Only after ideas are exhausted does the group move to evaluating each option against its established criteria.
Beyond problem solving, groups also make routine decisions, effect broader change, negotiate conflict, foster creativity ("two heads are better than one"), and maintain ties among stakeholders—people with an interest in an organization's actions.
Tools such as shared documents, file-sharing platforms, project-management apps, video conferencing, and team-chat applications help groups collaborate, especially in remote or hybrid settings. Technology does not automatically improve group communication, however—computer-mediated groups must work harder to explicitly establish norms and structure, since those cues develop less naturally online than face-to-face.
