Two field experiments were designed to explore ambivalence-induced behavior toward people with disabilities in low-cost helping situations. In Experiment 1, confederates, who either rode in a wheelchair or walked, asked shoppers for a small sum of money and either provided a reason (positive presentation) or did not provide a reason (negative presentation) for the request. Contrary to prediction, more people with a physical disability than without a physical disability were helped, regardless of their presentation. In Experiment 2, the presence of confederates in wheelchairs resulted in significantly fewer violations of parking spaces reserved for people with handicaps.
