Extrasensory perception (ESP) also known as the sixth sense, is a paranormal ability about receiving information not gained through the recognized physical senses, but sensed with the mind. It is claimed to be more sophisticated than intuition and the knowledge obtained is usually received from dreams, astral projection, or psychic abilities.
Parapsychology is the study of alleged psychic phenomena and other paranormal claims, for example, those related to near-death experiences, synchronicity, apparitional experiences, etc. Criticized as being a pseudoscience, the majority of mainstream scientists reject it. Parapsychology has also been criticised by mainstream critics for claims by many of its practitioners that their studies are plausible despite a lack of convincing evidence after more than a century of research for the existence of any psychic phenomena.
Telepathy is the purported vicarious transmission of information from one person's mind to another's without using any known human sensory channels or physical interaction. The term was first coined in 1882 by the classical scholar Frederic W. H. Myers, a founder of the Society for Psychical Research (SPR), and has remained more popular than the earlier expression thought-transference.
A psychic is a person who claims to use extrasensory perception (ESP) to identify information hidden from the normal senses, particularly involving telepathy or clairvoyance, or who performs acts that are apparently inexplicable by natural laws, such as psychokinesis or teleportation. Although many people believe in psychic abilities, the scientific consensus is that there is no proof of the existence of such powers, and describes the practice as pseudoscience. The word "psychic" is also used as an adjective to describe such abilities.
In American science fiction of the 1950s and '60s, psionics was a proposed discipline that applied principles of engineering to the study of paranormal or psychic phenomena, such as extrasensory perception, telepathy and psychokinesis. The term is a blend word of psi and the -onics from electronics. The word "psionics" began as, and always remained, a term of art within the science fiction community and—despite the promotional efforts of editor John W. Campbell, Jr—it never achieved general currency, even among academic parapsychologists. In the years after the term was coined in 1951, it became increasingly evident that no scientific evidence supports the existence of "psionic" abilities.
Mentalism is a performing art in which its practitioners, known as mentalists, appear to demonstrate highly developed mental or intuitive abilities. Performances may appear to include hypnosis, telepathy, clairvoyance, divination, precognition, psychokinesis, mediumship, mind control, memory feats, deduction, and rapid mathematics. Mentalists perform a theatrical act that includes special effects that may appear to employ psychic or supernatural forces but that are actually achieved by "ordinary conjuring means", natural human abilities, and an in-depth understanding of key principles from human psychology or other behavioral sciences.

Rhine, was an American botanist who founded parapsychology as a branch of psychology, founding the parapsychology lab at Duke University, the Journal of Parapsychology, the Foundation for Research on the Nature of Man, and the Parapsychological Association. Rhine wrote the books Extrasensory Perception and Parapsychology: Frontier Science of the Mind.

Rudi Schneider, son of Josef Schneider and brother of Willi Schneider, was an Austrian Spiritualist and physical medium. His career was covered extensively by the Journal of the American Society for Psychical Research, and he took part in a number of notable experiments conducted by paranormal researchers/debunkers, including Harry Price, Albert von Schrenck-Notzing and Eric Dingwall. Some of these researchers declared him to be a fraud while others were unable to find evidence of trickery.

Eileen Jeanette Vancho Lyttle Garrett was an Irish medium and parapsychologist. Garrett's alleged psychic abilities were tested in the 1930s by Joseph Rhine and others. Rhine claimed that she had genuine psychic abilities, but subsequent studies were unable to replicate his results, and Garrett's abilities were later shown to be consistent with chance guessing. Garrett elicited controversy after the R101 crash, when she held a series of séances at the National Laboratory of Psychical Research claiming to be in contact with victims of the disaster. John Booth, and others, investigated her claims, and found them to be valueless, easily explainable, or the result of fraud.
Walter Franklin Prince was an American parapsychologist and founder of the Boston Society for Psychical Research in Boston.
Telekinesis is a hypothetical psychic ability allowing a person to influence a physical system without physical interaction. Experiments to prove the existence of telekinesis have historically been criticized for lack of proper controls and repeatability. There is no reliable evidence that telekinesis is a real phenomenon, and the topic is generally regarded as pseudoscience.
