(German for "uniform or whole field"). A sensory-deprivation protocol for inducing a state of consciousness between wakefulness and sleep; in parapsychology, the ganzfeld is typically used in association with telepathy experiments.
A technique for investigating ESP in which the person experiences an absence of patterned stimulation. This generally involves the subject wearing halved table-tennis balls over the eyes while listening to hiss, or white noise, through headphones.
A clinical technique for investigating PSI Phenomena, in which the test subject experience an absence of patterned stimulation. This technique generally involves the subject wearing halved table tennis balls over the eyes while listening to either white or pink noise signals through a headset to induce a state of mild sensory deprivation by providing 'homogenous' sensory fields.
Homogeneous environment created for a percipient by playing white noise to him through headphones and also furnished a uniform visual field for him by (for example) wearing translucent goggles.
German for "total field". A device for exploring the total visual field. The "pocket Ganzfeld", consisted of two half ping-pong balls placed over the two eyes, produced the same effect as the original Ganzfeld - a six-foot diameter hemisphere.
An experimental technique in which the subject is placed into an altered state of consciousness (through sensory deprivation) in order to facilitate ESP; typically tests for telepathic ability.
