What Is RSPK?
RSPK stands for Recurrent Spontaneous Psychokinesis — the scientific term used in parapsychology to describe what is commonly known as poltergeist activity. The term was coined by researcher William G. Roll to provide a testable hypothesis for cases involving objects moving or being thrown, unexplained noises, electrical disturbances, and other physical phenomena that recur over a period of time in association with a specific individual or location.
The Poltergeist Hypothesis
The RSPK framework represents a significant departure from traditional interpretations of poltergeist activity. Rather than attributing the phenomena to ghosts, spirits, or external entities, the RSPK hypothesis proposes that the physical disturbances originate from a living person — typically called the “agent” or “focus person” — who unconsciously generates PK (Psychokinesis) that manifests as physical disturbances in the environment. This hypothesis was developed through the observation that poltergeist cases frequently center on a specific individual, and the phenomena tend to cease when that person is removed from the environment.
The Agent Profile
Research into RSPK cases has identified a recurring profile for the focus person. The agent is most commonly an adolescent or young adult, frequently female, who is experiencing significant psychological stress, repressed anger, or emotional turmoil. Roll and other researchers proposed that the inability to express or process intense emotions through normal channels leads to an unconscious externalization of psychic energy that produces physical effects. This model draws on psychodynamic psychology and proposes a mechanism where psychological pressure is converted into physical force.
Classic Cases
Several extensively investigated RSPK cases have contributed to the research literature. The Miami poltergeist case (1967), investigated by Roll and J.G. Pratt, involved objects repeatedly falling from shelves in a warehouse, with activity centering on a young employee. The Enfield poltergeist (1977-1978) in London involved extensive witnessed phenomena including furniture movement, knocking, and a child’s alleged levitation. The Rosenheim poltergeist (1967) in Germany was notable for occurring in an office environment, with electrical disturbances documented by physicists from the Max Planck Institute.
Skeptical Perspective
Skeptics argue that RSPK cases can be explained by deliberate fraud (often by the focus person seeking attention), unconscious or conscious trickery, misperception of normal events, and investigator bias. In several high-profile cases, the agent was caught producing phenomena through normal means, undermining the credibility of those specific cases. Critics also note that the PK mechanism proposed in the RSPK hypothesis has no established physical basis.
Related Terms
RSPK is connected to PK (Psychokinesis), PSI (Parapsychological Phenomena), and the broader field of parapsychological research conducted at institutions including DOPS (Division of Perceptual Studies) and SPR (Society for Psychical Research). Investigation of RSPK cases also involves tools standard in paranormal investigation including EMF (Electromagnetic Field) detection and EVP (Electronic Voice Phenomenon) recording.
