Oops. You're right, Wolfgang. I see my mistake now.

Dianavan, I don't think I can agree with you. Group dynamics are an important part of behavioral psychology. Behavioral psychology does not just deal with individuals. The size of the group is not important. Sociology also deals with groups of people (in different ways), and it can also be used as a tool for understanding why these kinds of things happen. But to not address group dynamics from the perspective of behavioral psychology leaves a very big hole in the total picture.
