Parapsychology in the context of "Joseph Banks Rhine"

The occult (from Latin occultus 'hidden, secret') is a category of esoteric or supernatural beliefs and practices which generally fall outside the scope of organized religion and science, encompassing phenomena involving a 'hidden' or 'secret' agency, such as magic and mysticism. It can also refer to paranormal ideas such as extra-sensory perception and parapsychology.

The term occult sciences was used in 16th-century Europe to refer to astrology, alchemy, and natural magic. The term occultism emerged in 19th-century France, among figures such as Antoine Court de Gébelin. It came to be associated with various French esoteric groups connected to Éliphas Lévi and Papus, and in 1875 was introduced into the English language by the esotericist Helena Blavatsky.

Kirlian photography is a collection of photographic techniques used to capture the phenomenon of electrical coronal discharges. It is named after Soviet inventor and researcher of Armenian descent Semyon Kirlian, who, in 1939, accidentally discovered that if an object on a photographic plate is connected to a high-voltage source, an image is produced on the photographic plate.The technique has been variously known as"electrographyelectrophotographycorona discharge photography" (CDP),"bioelectrographygas discharge visualization (GDV)electrophotonic imaging (EPI)", and, in Russian literature, "Kirlianography".

Kirlian photography has been the subject of scientific research, parapsychology research, and art. Paranormal claims have been made about Kirlian photography, but these claims are rejected by the scientific community. To a large extent, it has been used in alternative medicine research.

Sleep-learning or sleep-teaching (also known as hypnopædia or hypnopedia) is an attempt to convey information to a sleeping person, typically by playing a sound recording to them while they sleep. Although sleep is considered an important period for memory consolidation, scientific research has concluded that sleep-learning is not possible. Once a concept explored in the early history of psychology, sleep-learning appears frequently in fiction and parapsychology, and is widely considered to be pseudoscience.

A psychic is a person who claims to use powers rooted in parapsychology, such as 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.

Psychics encompass people in a variety of roles. Some are theatrical performers, such as stage magicians, who use various techniques, e.g. prestidigitation, cold reading, and hot reading, to produce the appearance of such abilities for entertainment purposes. A large industry and network exist whereby people advertised as psychics provide advice and counsel to clients. Some famous psychics include Edgar Cayce, Ingo Swann, Peter Hurkos, Janet Lee, Miss Cleo, John Edward, Sylvia Browne, and Tyler Henry. Psychic powers are asserted by psychic detectives and in practices such as psychic archaeology and even psychic surgery.

Henry Habberley Price FBA (17 May 1899 – 26 November 1984), usually cited as H. H. Price, was a Welsh philosopher, known for his work on the philosophy of perception. He also wrote on parapsychology.

Clairvoyance (/klɛərˈvɔɪ.əns/; from French clair 'clear' and voyance 'vision') is the claimed ability to acquire information that would be considered impossible to get through scientifically proven sensations, thus classified as extrasensory perception, or "sixth sense". Any person who is claimed to have such ability is said to be a clairvoyant (/klɛərˈvɔɪ.ənt/) ('one who sees clearly').

Claims for the existence of paranormal and psychic abilities such as clairvoyance have not been supported by scientific evidence. Parapsychology explores this possibility, but the existence of the paranormal is not accepted by the scientific community. The scientific community widely considers parapsychology, including the study of clairvoyance, a pseudoscience.

In parapsychology, psychometry (from Greek: ψυχή, psukhē, "spirit, soul" and μέτρον, metron, "measure"), also known as token-object reading, or psychoscopy, is a form of extrasensory perception characterized by the purported ability to glean accurate knowledge of an object's history by making physical contact with that object. Supporters assert that an object may have an energy field that transfers knowledge regarding that object's history.

There is no evidence that psychometry exists, and the concept has been widely criticized.
