Most humans form self-identities through their communication with others, and much of that interaction occurs in a group context. A group may be defined as three or more individuals who affiliate, interact, or cooperate in a familial, social, or work context. Group communication may be defined as the exchange of information with those who are alike culturally, linguistically, and/or geographically. Group members may be known by their symbols, such as patches and insignia on a military uniform. They may be known by their use of specialized language or jargon. Group members may also be known by their proximity, as in gated communities. Regardless of how the group defines itself, and regardless of the extent to which its borders are porous or permeable, a group recognizes itself as a group. Humans naturally make groups a part of their context or environment.

Primary and Secondary Groups

There are fundamentally two types of groups, primary and secondary. The hierarchy denotes the degree to which the group(s) meet your interpersonal needs. Primary groups meet most, if not all, of one’s needs. Groups that meet some, but not all, needs are called secondary groups. Secondary groups often include work groups, where the goal is to complete a task or solve a problem. Secondary groups may meet your need for professional acceptance and celebrate your success, but they may not meet your need for understanding and sharing on a personal level.

If Two’s Company and Three’s a Crowd, What Is a Group?

This old cliché refers to the human tendency to form pairs. Pairing is the most basic form of relationship formation; it applies to childhood best friends, college roommates, romantic couples, business partners, and many other dyads (two-person relationships). A group, by definition, includes at least three people. We can categorize groups in terms of their size and complexity.

The larger the group grows, the more likely it is to subdivide. Analysis of these smaller, or microgroups, is increasingly a point of study as the internet allows individuals to join people of similar mind or habit to share virtually anything across time and distance. A microgroup is a small, independent group that has a link, affiliation, or association with a larger group. With each additional group member the number of possible interactions increases (Harris & Sherblom, 1999; McLean,, 2003).

Small groups normally contain between three and eight people. One person may involve intrapersonal communication, while two may constitute interpersonal communication, and both may be present within a group communication context.

Group norms are customs, standards, and behavioural expectations that emerge as a group forms. If you post an update every day on your Facebook page and your friends stop by to post on your wall and comment, not posting for a week will violate a group norm. They will wonder if you are sick or in the hospital where you have no access to a computer to keep them updated. If, however, you only post once a week, the group will come to naturally expect your customary post. Norms involve expectations that are self and group imposed and that often arise as groups form and develop.

If there are more than eight members, it becomes a challenge to have equal participation, where everyone has a chance to speak, listen, and respond. Some will dominate, others will recede, and smaller groups will form. Finding a natural balance within a group can also be a challenge. Small groups need to have enough members to generate a rich and stimulating exchange of ideas, information, and interaction, but not so many people that what each brings cannot be shared (Galanes, Adams, & Brilhart, 2000).
