Group Communication Theory

This resource will help you group your audience based on their common characteristics. It also introduces a group's roles, status, power, and hierarchy. The purposes of different groups in the workplace are explored.

What is a Group

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.

When we discuss demographic groups as part of a market study, we may focus on large numbers of individuals that share common characteristics. If you are the producer of an ecologically innovative car such as the Smart ForTwo, and know your customers have an average of four members in their family, you may discuss developing a new model with additional seats. While the target audience is a group, car customers don't relate to each other as a unified whole. Even if they form car clubs and have regional gatherings, a newsletter, and competitions at their local race tracks each year, they still subdivide the overall community of car owners into smaller groups.

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 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.

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. You may think to yourself before taking a speech turn or writing your next post, and you may turn to your neighbor or co-worker and have a side conversation, but a group relationship normally involves three to eight people.

In Table 2.1 "Possible Interaction in Groups", you can quickly see how the number of possible interactions grows according to how many people are in the group. At some point we all find the possible and actual interactions overwhelming, and subdivide into smaller groups. Forums may have hundreds or thousands of members, and you may have hundreds of friends on MySpace or FaceBook, but how many do you regularly communicate with? You may be tempted to provide a number well north of eight, but if you exclude the "all to one" messages, such as a general Twitter to everyone (but no one person in particular), you'll find the group norms will appear.

Group norms are customs, standards, and behavioral expectations that emerge as a group forms. If you blog everyday on your FaceBook page, and your friends stop by to post on your wall and comment, and then stop for a week, you'll violate a group norm. They will wonder if you are sick or in the hospital where you can't access 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, self and group imposed, 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, be heard, 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.
