Participant in a 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 ...
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.
Hallucinations caused by sensory deprivation can, like ganzfeld-induced hallucinations, turn into complex scenes. [4] William G. Braud with Charles Honorton were the first to modify the ganzfeld procedure for parapsychological use. [5] The effect is a component of the Ganzfeld experiment, a technique used in the field of parapsychology. [6]
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 ]
White torture, often referred to as white room torture, is a type of psychological torture [1] [2] technique aimed at complete sensory deprivation and isolation. A prisoner is held in a cell, devoid of any color besides white, that is designed to deprive them of all senses and identity. [2] [3] [4]
John C. Lilly developed the first sensory deprivation tanks and self-experimented them with the intention to study the origin of consciousness and its relation to the brain by creating an environment which isolates an individual from external stimulation.
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] The aim of the research was to produce an animal model of depression.
