Term: ganzfeld

German for "entire field," it is an experimental technique originally devised in the 1930s by Wolfgang Metzger for investigating a psychological theory. Some parapsychologists have used the protocol as a way of increasing ESP. Generally, the technique forces a subject to turn inward through a type of sensory deprivation. The subject hears only white or pink noise. Ping pong balls are cut in half and placed over the eyes with red lights shined upon them. This bland environment supposedly results in a person turning inward for stimulation, resulting in enhanced senses: ESP. Some researchers have declared that the results are strongly and quantifiably successful, but others say the results are non conclusive.
