"My historical research was really on the history of an idea. That idea is that the intelligence of the poltergeist possibly resided in the unconscious of a living person who seemed to be at the centre of the physical manifestations. The concept that a person could have an energetic relationship with their physical environment—mind over matter, or psychokinesis—really took hold alongside emerging studies of physics, microbiology, and psychology in the late nineteenth and early twentieth centuries. I examined how that idea became prominently accepted by mid-twentieth century parapsychologists, bringing about a term, recurrent spontaneous psychokinesis (RSPK)".
