Apparitional
In parapsychology, an apparitional experience is an anomalous experience characterized by the apparent perception of either a living being or an inanimate object without there being any material stimulus for such a perception. In academic discussion, the term "apparitional experience" is preferred to the term "ghost" because: # The term ghost implies that some element of the human being survives death and, at least under certain circumstances, can make itself perceptible to living human beings. There are other competing explanations of apparitional experiences. # Firsthand accounts of apparitional experiences differ in many respects from their fictional counterparts in literary or traditional ghost stories and films (see below). # The content of apparitional experiences includes living beings, both human and animal, and even inanimate objects. History Attempts to apply modern scientific or investigative standards to the study of apparitional experiences began with the work of ...

Hallucinations In The Sane
Anomalous experiences, such as so-called benign hallucinations, may occur in a person in a state of good mental and physical health, even in the apparent absence of a transient trigger factor such as fatigue, intoxication or sensory deprivation. The evidence for this statement has been accumulating for more than a century. Studies of benign hallucinatory experiences go back to 1886 and the early work of the Society for Psychical Research, which suggested approximately 10% of the population had experienced at least one hallucinatory episode in the course of their life. More recent studies have validated these findings; the precise incidence found varies with the nature of the episode and the criteria of "hallucination" adopted, but the basic finding is now well-supported. Types Of particular interest, for reasons to be discussed below, are those anomalous experiences which are characterised by extreme perceptual realism. Apparitional experiences A common type of anomalous experi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parapsychology
Parapsychology is the study of alleged psychic phenomena (extrasensory perception, telepathy, teleportation, precognition, clairvoyance, psychokinesis (also called telekinesis), and psychometry (paranormal), 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 been criticised for continuing investigation despite being unable to provide reproducible evidence for the existence of any psychic phenomena after more than a century of research. Parapsychology research rarely appears in mainstream scientific journals; a few niche journals publish most papers about parapsychology. Terminology The term ''parapsychology'' was coined in 1889 by philosopher Max Dessoir as the German . It was adopted by Joseph Banks Rhine, J. B. Rhine in the 1930s as a replacement for the term ''psychical research'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schizotypy
In psychology, schizotypy is a theoretical concept that posits a continuum (theory), continuum of personality psychology, personality characteristics and experiences, ranging from normal dissociative, imaginative states to extreme states of mind related to psychosis, especially schizophrenia. The continuum of personality proposed in schizotypy is in contrast to a categorical view of psychosis, wherein psychosis is considered a particular (usually pathological) state of mind, which the person either has or does not have. Development of the concept The categorical view of psychosis is most associated with Emil Kraepelin, who created criteria for the medical diagnosis and classification of different forms of psychotic illness. Particularly, he made the distinction between dementia praecox (now called schizophrenia), manic depression, manic depressive insanity and non-psychotic states. Modern diagnostic systems used in psychiatry (such as the Diagnostic and Statistical Manual of Ment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallucination
A hallucination is a perception in the absence of an external stimulus that has the compelling sense of reality. 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. Hallucinations can occur in any sensory modality— visual, auditory, olfactory, gustatory, tactile, proprioceptive, equilibrioceptive, nociceptive, thermoceptive and chronoceptive. Hallucinations are referred to as multimodal if multiple sensory modalities occur. A mild form of hallucination is known as ...
