In the area of Parapsychology, the experiences of Prof. Rhine were decisive, as well as the one of Pratt and Woodruf. The study of certain individuals having the ability to foresee stochastic events, were studied intensely in its statistical slope.
This Project of Investigation sought to repeat the classical tests, introducing a new study element: the variations of the cerebral waves Alpha, Beta and Theta (7,9/13 Hz - 3,9/7,9 Hz - 13/20 Hz), and the use of disturbance factors: a generator of high-frequency electric field (Tesla type), a radio-frequency generator and an audio-frequency generator.
237 validated experiments were taken, with a margin of experimental error estimated in 6,5%. This study suggests that special phenomena of foreseeing don't exist, if the subject doesn't surpass a rate of successes of 40%. The introduced disturbance factors didn't have relevance in the aspects of radio-frequency and audio, not representing the distributions, private variations. On the other hand, the generator of electrical field shows that the subject can be driven to a state of “confusion” that turns him unable to obtain normal results. In this matter, the curve without interference’s possesses a maximum at 20% of successes, and with the interference, it possesses a maximum in 8% of successes.
This findings reveal an unsuspected probability of a “psi-missing” factor in the presence of an electrical alternate field (30 KV/10 KHz at 1 m).
