Being frightened, heart pounding, adrenaline pumping, cold-sweat fear, is not an enjoyable experience. Except when it is. Just look at the popularity of haunted houses, horror films and novels. People like a good scare, under the right circumstances. With us this Halloween to take a look at why so many of us seek out things that frighten us are Miami University psychology professor Dr. Elizabeth Kiel; Gary Vaughn, associate professor of English at University of Cincinnati's McMicken College of Arts and Science; and joining us from Pittsburgh public radio WESA, Dr. Margee Kerr, a sociologist at the University of Pittsburgh and Chatham University who studies the science of fear. Dr. Kerr is an advisor for ScareHouse in Pittsburgh, which has been ranked as one of America's Scariest Halloween Attractions by the Travel Channel.
