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] |

Paranormal
Paranormal events are purported phenomena described in popular culture, folk, and other non-scientific bodies of knowledge, whose existence within these contexts is described as being beyond the scope of normal scientific understanding. Notable paranormal beliefs include those that pertain to extrasensory perception (for example, telepathy), spiritualism and the pseudosciences of ghost hunting, cryptozoology, and ufology. Proposals regarding the paranormal are different from scientific hypotheses or speculations extrapolated from scientific evidence because scientific ideas are grounded in empirical observations and experimental data gained through the scientific method. In contrast, those who argue for the existence of the paranormal explicitly do not base their arguments on empirical evidence but rather on anecdote, testimony, and suspicion. The standard scientific models give the explanation that what appears to be paranormal phenomena is usually a misinterpretation, mi ...

Meta-analysis
A meta-analysis is a statistical analysis that combines the results of multiple scientific studies. Meta-analyses can be performed when there are multiple scientific studies addressing the same question, with each individual study reporting measurements that are expected to have some degree of error. The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived. Meta-analytic results are considered the most trustworthy source of evidence by the evidence-based medicine literature.Herrera Ortiz AF., Cadavid Camacho E, Cubillos Rojas J, Cadavid Camacho T, Zoe Guevara S, Tatiana Rincón Cuenca N, Vásquez Perdomo A, Del Castillo Herazo V, & Giraldo Malo R.

Documentation
Documentation is any communicable material that is used to describe, explain or instruct regarding some attributes of an object, system or procedure, such as its parts, assembly, installation, maintenance and use. As a form of knowledge management and knowledge organization, documentation can be provided on paper, online, or on digital or analog media, such as audio tape or CDs. Examples are user guides, white papers, online help, and quick-reference guides. Paper or hard-copy documentation has become less common. Documentation is often distributed via websites, software products, and other online applications. Documentation as a set of instructional materials shouldn't be confused with documentation science, the study of the recording and retrieval of information. Principles for producing documentation While associated ISO standards are not easily available publicly, a guide from other sources for this topic may serve the purpose.,, Documentation development may involve d ...

Sensory Leakage
Sensory leakage is a term used to refer to information that transferred to a person by conventional means (other than psi) during an experiment into ESP.Robert Todd Carroll. (2014)"Sensory Leakage in The Skeptic's Dictionary. For example, where the subject in an ESP experiment receives a visual cue—the reflection of a Zener card in the holder's glasses—sensory leakage can be said to have occurred. History Scientists such as Donovan Rawcliffe (1952), C. E. M. Hansel (1980), Ray Hyman (1989) and Andrew Neher (2011) have studied the history of psi experiments from the late 19th century up until the 1980s. In every experiment investigated, flaws and weaknesses were discovered so the possibility of naturalistic explanations (such as sensory cues) or deception and trickery were not ruled out. The data from the Creery sisters and the Soal-Goldney experiments were proven to be fraudulent, one of the subjects from the Smith-Blackburn experiments confessed to fraud, the Brugmans' exp ...

Ray Hyman
Ray Hyman (born June 23, 1928) is a Professor Emeritus of Psychology at the University of Oregon in Eugene, Oregon, and a noted critic of parapsychology. Hyman, along with James Randi, Martin Gardner and Paul Kurtz, is one of the founders of the modern skeptical movement. He is the founder and leader of the Skeptic's Toolbox. Hyman serves on the Executive Council for the Committee for Skeptical Inquiry. Career Hyman was born in Chelsea, Massachusetts. In his teenage years and later while attending Boston University, he worked as a magician and mentalist, impressing the head of his department (among others) with his palmistry. Hyman at one point believed that 'reading' the lines on a person's palm could provide insights into their nature, but later discovered that the person's reaction to the reading had little to do with the actual lines on the palm. This fascination with why this happened led him to switch from a journalist degree to psychology. JREF president D.J. Grothe as ...

Parapsychological Association
The Parapsychological Association (PA) was formed in 1957 as a professional society for parapsychologists following an initiative by Joseph B. Rhine. Its purpose has been "to advance parapsychology as a science, to disseminate knowledge of the field, and to integrate the findings with those of other branches of science." The work of the association is reported in the ''Journal of Parapsychology'' and the ''Journal of the American Society for Psychical Research''. (primary source) The Parapsychological Association became affiliated with the American Association for the Advancement of Science in 1969, and it is still an affiliate as of 2019. History The Association was created in Durham, North Carolina, on June 19, 1957. Its formation was proposed by Rhine, then Director of the Duke Parapsychology Laboratory at Duke University, at a ''Workshop in Parapsychology'' held there. Using the occasion afforded by this wide representation of the field, Rhine proposed that the group form its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trait Theory
In psychology, trait theory (also called dispositional theory) is an approach to the study of human personality. Trait theorists are primarily interested in the measurement of ''traits'', which can be defined as habitual patterns of behaviour, thought, and emotion. According to this perspective, traits are aspects of personality that are relatively stable over time, differ across individuals (e.g. some people are outgoing whereas others are not), are relatively consistent over situations, and influence behaviour. Traits are in contrast to states, which are more transitory dispositions. In some theories and systems, traits are something a person either has or does not have, but in many others traits are dimensions such as extraversion vs. introversion, with each person rating somewhere along this spectrum. There are two approaches to define traits: as internal causal properties or as purely descriptive summaries. The internal causal definition states that traits influence our behav ...

Pink Noise
Pink noise or noise is a signal or process with a frequency spectrum such that the power spectral density (power per frequency interval) is inversely proportional to the frequency of the signal. In pink noise, each octave interval (halving or doubling in frequency) carries an equal amount of noise energy. Pink noise sounds like a waterfall. It is often used to tune loudspeaker systems in professional audio. Pink noise is one of the most commonly observed signals in biological systems. The name arises from the pink appearance of visible light with this power spectrum. This is in contrast with white noise which has equal intensity per frequency interval. Definition Within the scientific literature, the term 1/f noise is sometimes used loosely to refer to any noise with a power spectral density of the form S(f) \propto \frac, where ''f'' is frequency, and 0 < α < 2, with exponent α usually close to 1. One-dimensional signals with α = 1 are usually called pink noise. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Noise
In signal processing, white noise is a random signal having equal intensity at different frequencies, giving it a constant power spectral density. The term is used, with this or similar meanings, in many scientific and technical disciplines, including physics, acoustical engineering, telecommunications, and statistical forecasting. White noise refers to a statistical model for signals and signal sources, rather than to any specific signal. White noise draws its name from white light, although light that appears white generally does not have a flat power spectral density over the visible band. In discrete time, white noise is a discrete signal whose samples are regarded as a sequence of serially uncorrelated random variables with zero mean and finite variance; a single realization of white noise is a random shock. Depending on the context, one may also require that the samples be independent and have identical probability distribution (in other words independent and iden ...

American Society For Psychical Research
The American Society for Psychical Research (ASPR) is the oldest psychical research organization in the United States dedicated to parapsychology. It maintains offices and a library, in New York City, which are open to both members and the general public. The society has an open membership, anyone with an interest in psychical research is invited to join. It maintains a website; and publishes the quarterly ''Journal of the American Society for Psychical Research''. History It was William Fletcher Barrett's visit to America that ultimately led to the formation of the American Society for Psychical Research in December, 1884.Fichman, Martin. (2004). ''An Elusive Victorian: The Evolution of Alfred Russel Wallace''. University of Chicago Press. p. 111. Barrett was invited by several members of the American Association for the Advancement of Science.

Sharon Harper
Sharon Harper (born in Stamford, Connecticut in 1966) is a contemporary visual artist, based in Cambridge, Massachusetts. Harper is interested in photography as it relates to perceptual experiences between humans and the natural environment. Harper is currently professor of Visual and Environmental Studies at Harvard University. Work Harper's photographs examine human perception of time through the movements of the sun, moon, and stars, as mediated by a large format camera. Harper is known for her series "Moon Studies and Star Scratches," in which she uses multiple exposures on large format film to overlap weeks or months of nightly images of the moon and stars to create records of perceptual experience over time. Museum Collections Harper's photographs are in the permanent collections of major institutions such as the Museum of Modern Art, New York, the Whitney Museum of American Art, New York, the Albright-Knox Art Gallery in Buffalo, New York, the Museum of Fine Arts, Houst ...
