Groups within the electronic realm share many characteristics in common with groups that meet and function in shared physical spaces. Groups in both domains can be quite diverse in terms of the composition and personality characteristics of members, the purpose and goals of the group, and the contextual setting in which the group functions. A variety of factors likely affect and influence the structure and functioning of any given group. Many, if not most, of these factors can potentially influence the group, regardless of the domain (electronic or face-to-face) and produce similar outcomes. There are qualities of electronic communication settings and qualities of physical settings that can uniquely influence the dynamics of a group in those respective settings (see McKenna & Green, 2002; McKenna & Seidman, 2005 for reviews).
This chapter delves into the workings of online groups and examines potentially influential factors for group functioning. The chapter is divided into three sections, which examine (1) the role of the motivations and personality characteristics of individual members within the group, (2) the way in which different categories or kinds of online groups distinctly function (including support groups), and (3) aspects of the internal dynamics of online groups, such as cohesiveness, status and stereotypes, and performance.
Individuals and Groups
Individual motivations of members
Classical motivation theory indicates that all behavior is motivated in some way and that an individual will engage in particular behaviors to further a desired end (e.g., Atkinson & Birch, 1970; Lewin, 1951).
