"Aggression is one of the most troubling facets of the human experience. As we know from the nightly news, aggression causes people to harm people they know, people they love, and people they've never met. Some people cause harm because they feel too much, whereas others do so because they don't feel much at all. Our genes influence whether we'll respond to an insult with aggression--but so does our culture. So the better question to ask might be this: Why don't more people behave aggressively? In this engaging fifteen-lecture course, Professor DeWall walks you through the briar patch of aggression to answer all your questions about the root causes of hostile behavior. Incorporating vivid case studies and psychological research, the lectures challenge you to reconsider what you think you know about aggression and offer practical tools to prevent it in your daily life. Listen along with Professor DeWall today for an in-depth look at this fascinating but troubling aspect of human behavior." -- Amazon web site.
