This chapter analyzes social groups, highlighting the differences between them. Two or more people who identify and interact with one another. A small social group whose members share personal and lasting relationships. Cooley called this type of group primary because they: Large and impersonal groups whose members pursue a specific goal or activity. *people look to one another strategically (for what they can do for one another) *part of a secondary group could turn itself into a primary group. *important element of group dynamics is leadership. *small circles of friends may have no leader at all. *however large secondary groups place leaders in a formal chain of command. *leaders make plans, give orders, and get things done. *leaders raise group morale and minimize tension and conflict among members. There are 3 kinds of leadership styles: *authoritarian: makes decisions; demands that group members obey. *appreciated in a crisis: *democratic: member involvement in decision making.
