A technique that uses the ganzfeld effect to test individuals for extrasensory perception (ESP). In the experiment, participants are placed in a room in comfortable armchairs, Table tennis balls cut in half over his eyes, playing white noise headphones, and a red light shining on them for half an hour. During the time of participants was somewhat deprived from changing the stimulus, "the sender" trying to mentally send out information about the objects that were selected randomly. Participants speak loudly for that half an hour about what he can see. After half an hour is over, the participants were taken out of the country and presented a series of ganzfeld objects. Participants must select object that most closely resembles the picture they saw during the trial.
