Ganzfeld Effect
The Ganzfeld effect (from German for "complete field"), or perceptual deprivation, is a phenomenon of perception caused by exposure to an unstructured, uniform stimulation field. The effect is the result of the brain amplifying neural noise in order to look for the missing visual signals. The noise is interpreted in the higher visual cortex, and gives rise to hallucinations. It has been most studied with vision by staring at an undifferentiated and uniform field of color. The visual effect is described as the loss of vision as the brain cuts off the unchanging signal from the eyes. The result is "seeing black", an apparent sense of blindness. A flickering ganzfeld causes geometrical patterns and colors to appear, and this is the working principle for mind machines and the dream machine. Ganzfeld induction in multiple senses is called multi-modal ganzfeld. This is usually done by wearing ganzfeld goggles in addition to headphones with a uniform stimulus. A related effect is se ...

German Language
German ( ) is a West Germanic languages, West Germanic language mainly spoken in Central Europe. It is the most widely spoken and Official language, official or co-official language in Germany, Austria, Switzerland, Liechtenstein, and the Italy, Italian province of South Tyrol. It is also a co-official language of Luxembourg and German-speaking Community of Belgium, Belgium, as well as a national language in Namibia. Outside Germany, it is also spoken by German communities in France (Bas-Rhin), Czech Republic (North Bohemia), Poland (Upper Silesia), Slovakia (Bratislava Region), and Hungary (Sopron).

Ganzfeld Experiment
A ganzfeld experiment (from the German words for “entire” and “field”) is an assessment used by parapsychologists that they contend can test for extrasensory perception (ESP) or telepathy. In these experiments, a "sender" attempts to mentally transmit an image to a "receiver" who is in a state of sensory deprivation. The receiver is normally asked to choose between a limited number of options for what the transmission was supposed to be and parapsychologists who propose that such telepathy is possible argue that rates of success above the expectation from randomness are evidence for ESP. Consistent, independent replication of ganzfeld experiments has not been achieved, and, in spite of strenuous arguments by parapsychologists to the contrary, there is no validated evidence accepted by the wider scientific community for the existence of any parapsychological phenomena. Ongoing parapsychology research using ganzfeld experiments has been criticized by independent reviewers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prisoner's Cinema
Prisoner's cinema is the phenomenon of a "light show" of various colors that appear out of the darkness. The light has a form, but those that have seen it find it difficult to describe. Sometimes, the cinema lights resolve into human or other figures. The phenomenon is reported by prisoners confined to dark cells and by others kept in darkness, voluntarily or not, for long periods of time. It has also been reported by truck drivers, pilots, and practitioners of intense meditation. Astronauts and other individuals who have been exposed to certain types of radiation have reported witnessing similar phenomena. Scientists believe that the cinema is a result of phosphenes combined with the psychological effects of prolonged lack of exposure to light, and others have noted a connection between the form the lights take and neolithic cave paintings. Popular culture The pilot episode for the original ''Twilight Zone'' series, "Where Is Everybody?," depicts elaborate, fully realistic hallu ...

Pythagoras
Pythagoras of Samos ( grc, Πυθαγόρας ὁ Σάμιος, Pythagóras ho Sámios, Pythagoras the Samos, Samian, or simply ; in Ionian Greek; ) was an ancient Ionians, Ionian Ancient Greek philosophy, Greek philosopher and the eponymous founder of Pythagoreanism. His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, the Western philosophy, West in general. Knowledge of his life is clouded by legend, but he appears to have been the son of Mnesarchus, a gem-engraver on the island of Samos. Modern scholars disagree regarding Pythagoras's education and influences, but they do agree that, around 530 BC, he travelled to Crotone, Croton in southern Italy, where he founded a school in which initiates were sworn to secrecy and lived a communal, asceticism, ascetic lifestyle. This lifestyle entailed a number of dietary prohibitions, traditionally said to have included vegetarianism, although m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electroencephalogram
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The biosignals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp EEG") using the International 10-20 system, or variations of it. Electrocorticography, involving surgical placement of electrodes, is sometimes called " intracranial EEG". Clinical interpretation of EEG recordings is most often performed by visual inspection of the tracing or quantitative EEG analysis. Voltage fluctuations measured by the EEG bioamplifier and electrodes allow the evaluation of normal brain activity. As the electrical activity monitored by EEG originates in neurons in the underlying brain tissue, the recordings made by the electrodes on the surface of the scalp vary in accordance with their orientation and ...

Hallucination
A hallucination is a perception in the absence of an external stimulus that has the qualities of a real perception. Hallucinations are vivid, substantial, and are perceived to be located in external objective space. Hallucination is a combination of 2 conscious states of brain wakefulness and REM sleep. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from "delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Many hallucinations happen also during sleep paralyses. Hallucinations can occur in any sensory modality—visual, auditory, olfa ...

Wolfgang Metzger
Wolfgang Metzger (born 22 July 1899 in Heidelberg, Germany; died 20 December 1979 in Bebenhausen, Germany) is considered one of the main representatives of Gestalt psychology (Gestalt theory) in Germany. Metzger's most widely acclaimed work is ''Psychologie: Die Entwicklung ihrer Grundannahmen seit der Einführung des Experiments'' (Psychology: The development of basic principles since the introduction of the experimental method). It portrays systematically the foundations of psychology, including the different kinds of psychological reality, the problems associated with reference systems, order, and much more. Pivotal in its discussions is the cumulative knowledge, at that time, of the entire Gestalt school. Biography Metzger was a student and associate of the founders of the Berlin school of Gestalt theory, Max Wertheimer, Wolfgang Köhler and Kurt Koffka. Metzger became Max Wertheimer's assistant in Frankfurt/Main in the 1930s and his successor when the Nazis forced Wertheimer ...

Psychological Bulletin
The ''Psychological Bulletin'' is a monthly peer-reviewed academic journal that publishes evaluative and integrative research reviews and interpretations of issues in psychology, including both qualitative (narrative) and/or quantitative (meta-analytic) aspects. The editor-in-chief is Dolores Albarracín (University of Illinois at Urbana–Champaign). History The journal was established by Johns Hopkins psychologist James Mark Baldwin in 1904,Benjamin, Ludy T. ''A Brief History of Modern Psychology''. Malden, MA: Blackwell Pub., 2007, pp. 70–1, . immediately after he had bought out James McKeen Cattell's share of ''Psychological Review'', which the two had established ten years earlier. Baldwin gave the editorship of both journals to John B. Watson, when scandal forced him to resign his position at Johns Hopkins in 1920. Ownership of the ''Bulletin'' passed to Howard C. Warren, who eventually donated it to the American Psychological Association, which continues to own it to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parapsychology
Parapsychology is the study of alleged psychic phenomena (extrasensory perception, telepathy, precognition, clairvoyance, psychokinesis (also called telekinesis), and psychometry) 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 many of its practitioners claiming that their studies are plausible in spite of there being no convincing evidence for the existence of any psychic phenomena after more than a century of research. Parapsychology research rarely appears in mainstream scientific journals; instead, most papers about parapsychology are published in a small number of niche journals. Terminology The term ''parapsychology'' was coined in 1889 by philosopher Max Dessoir as the German . It was adopted by J. B. Rhine in the 1930s as a replacement fo ...

Perception
Perception () is the organization, identification, and interpretation of sensory information in order to represent and understand the presented information or environment. All perception involves signals that go through the nervous system, which in turn result from physical or chemical stimulation of the sensory system.Goldstein (2009) pp. 5–7 Vision involves light striking the retina of the eye; smell is mediated by odor molecules; and hearing involves pressure waves. Perception is not only the passive receipt of these signals, but it is also shaped by the recipient's learning, memory, expectation, and attention. Gregory, Richard. "Perception" in Gregory, Zangwill (1987) pp. 598–601. Sensory input is a process that transforms this low-level information to higher-level information (e.g., extracts shapes for object recognition). The process that follows connects a person's concepts and expectations (or knowledge), restorative and selective mechanisms (such as ...

Charles Honorton
Charles Henry Honorton (February 5, 1946 – November 4, 1992) was an American parapsychologist and was one of the leaders of a collegial group of researchers who were determined to apply established scientific research methods to the examination of what they called "anomalous information transfer" (extrasensory perception) and other phenomena associated with the "mind/body problem"—the idea that mind might, at least in some respects, have a physical existence independent of the body. Biography Over several decades, Honorton conducted many experiments, the most famous and significant of which involved the use of the Ganzfeld experiment technique for creating a state of sensory deprivation. His hypothesis was that the information "channel," or transfer mechanism, in ESP was "weak" and easily diluted or drowned out by normal sensory input. Honorton rejected the term parapsychology, instead preferring to approach extra-sensory perception as one would any other area of psychophy ...
