Title: "What's the norm here?"
Description: Social categorization processes may lead work groups to form different types of group norms. We present a model of norm formation and suggest that group norms may emerge immediately following the group's inception. Further, the content of such norms may be influenced by group members' demographic heterogeneity. We outline a profile of work group norms and describe how social categorization processes influence the norm formation process. We also develop a series of testable propositions related to these norms. Finally, we discuss the implications of our social categorization model for future research on work groups in organizations.
