This chapter deals with moral courage. We seek to highligh this construc by comparing it with other prosocial behaviors,such as helping behavior and related constructs such as heroism or social control. We also include research about classical determinants of helping behavior that do not affect moral courage,followed by studies about determinants that foster moral courageous behavior. Models for moral courage as well as scales to measure it are presented. Finally,we discuss a practical implementation of our research:moral courage trainings.
