Sensory deprivation or perceptual isolation [1] is the deliberate reduction or removal of stimuli from one or more of the senses. Simple devices such as blindfolds or hoods and earmuffs can cut off sight and hearing, while more complex devices can also cut off the sense of smell, touch, taste, thermoception (heat-sense), and the ability to know which way is down.
Honorton focused on what he thought was the connection between ESP and dreams and began exposing his research subjects to the same sort of sensory deprivation that is used in demonstrations of the ganzfeld effect, hypothesizing that it was under such conditions that "psi" (a catch-all term used in parapsychology to denote anomalous psychic ...
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. [1] The effect is the result of the brain amplifying neural noise in order to look for the missing visual signals.
The Montreal experiments were a series of experiments, initially aimed to treat schizophrenia [1] by changing memories and erasing the patients' thoughts using the Scottish psychiatrist Donald Ewen Cameron's method of "psychic driving", [2] as well as drug-induced sleep, intensive electroconvulsive therapy, sensory deprivation and Thorazine.
The experiments were designed to study the behavioral and neural development of monkeys reared with a sensory substitution device. [ 2 ] [ 3 ] Acting on a tip-off from a student, the ALF removed Britches from the laboratory on April 20, 1985, when he was five weeks old. [ 4 ]
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 ...
The pit of despair was a name used by American comparative psychologist Harry Harlow for a device he designed, technically called a vertical chamber apparatus, that he used in experiments on rhesus macaque monkeys at the University of Wisconsin–Madison in the 1970s. [2]
Dual sensory loss is the simultaneous loss of two senses. Research has shown that 6% of non-institutionalized older adults had a dual sensory impairment, and 70% of severely visually impaired older adults additionally suffered from significant hearing loss. [7] Vision and hearing loss both interfere with the interpretation and comprehension of ...
