ABSTRACT
For those who teach students in psychology, education, and the social sciences, the Handbook of Demonstrations and Activities in the Teaching of Psychology, provides practical applications and rich sources of ideas. Teachers believe that classroom demonstrations promote students' awareness and understanding of psychological concepts and principles. Teachers can use this activity to illustrate that different sciences confront the same problem. The free-rider problem in economics, the irrationality of voting in political science, and the prisoner's dilemma in psychology all oppose group benefits with individual interests. Dynamic social impact theory predicts the emergence of lour group-level phenomena whenever people in spatially distributed groups, such as residents of an apartment complex or people at a banquet table, influence one another. Group norms, the set of implicit or explicit rules established by a group to regulate the behavior of its members, are studied in many psychology classes.
