The experimental setup is simple: a six-foot-wide, 60-foot-long corridor with a straight black line running along the floor. A blindfolded subject attempts to walk the line, and a researcher records any wobbles to the right or left. Christine Mohr, now a lecturer in experimental psychology and neuropsychology at the University of Bristol in England, designed the study for her doctoral dissertation at the University of Zurich. Before the study participants walked the line, Mohr asked them about parapsychology--specifically, their belief in so-called psi phenomena, including telepathy, clairvoyance and psychokinesis (using mental imagery to move objects).
