1 A person claiming to be psychic demonstrates his ability to find an underground source of water using a “dowsing rod.” As a psychologist, which tests would you like to use to test hypotheses about how the water was found? A. This psychic should have to find water several more times in order to prove the hypothesis that he is psychic correct B. The psychic should have to find water again under a condition that controls for all the other possible explanations, such as cheating, coincidence, non-verbal clues from the audience, etc. C. As a psychologist, I don’t need to test this claim because common sense has already dis-proven the possibility of psychic abilities. D. I would want to look at a videotape of the psychic demonstration frame by frame in order to determine where the deception occurred. E. The psychic should be asked to find underground water several more times, but each time a different possible explanation would be tested 8/24/04History, Perspectives
