Discrimination refers to positive or negative behaviour that is directed towards a social group and its members
Prejudice refers to a negative attitude towards members of a group, based solely on their group membership

A super-ordinate goal is one that cannot be achieved by any one group alone. Superordinate goals overrides other existing goals which each group might have
Mutual independence is two groups being somehow dependent upon one another to meet a goal (often the super-ordinate goal)
