What is parapsychology? The scientific study of behavior and experience is known as psychology. The study of abnormal behavior and experiences, often known as paranormal ones, is known as parapsychology. Time, distance, and force have no bearing on paranormal events. Extrasensory perception (ESP), which is the study of communications purportedly without the involvement of any known sensory organs, and psychokinesis (PK), which is the study of physical actions that appear to occur without the involvement of any recognized motor organs, are the two primary disciplines of parapsychology.
