The Psychology of Groups [Professor Name] [Class and Section Number]

Today’s Learning Objectives 1.Review the evidence that suggests humans have a fundamental need to belong to groups. 2.Compare the sociometer model of self-esteem to a more traditional view of self-esteem. 3.Use theories of social facilitation to predict when a group will perform tasks slowly or quickly (e.g., students eating a meal as a group, workers on an assembly line, or a study group). 4.Summarize the methods used by Latané, Williams, and Harkins to identify the relative impact of social loafing and coordination problems on group performance.

Today’s Learning Objectives 6.Describe how groups change over time. 7.Apply the theory of groupthink to a well-known decision- making group, such as the group of advisors responsible for planning the Space Shuttle Challenger operation. 8.List and discuss the factors that facilitate and impede group performance and decision-making. 9.Develop a list of recommendations that, if followed, would minimize the possibility of groupthink developing in a group.

Warm Up: How many groups?  List all the groups that you belong to.  Think about groups that involve your family, friends, and peers (school and/or work).
