Declassified and Approved For Release 2014/01/09: CIA-RDP79-00999A000200010006-9 Information transmission under conditions of sensory shielding WE present results of experiments ,suggesting the existence of one or more perceptual modalities through which individuals obtain information about their environment, although this information is not presented to any known sense. The litera- ture-3 and our observations lead us to 'conclude that such abilities can be studied under laboratory conditions. We have investigated the ability of certain people to describe graphical material or remote scenes shielded against ordinary perception. In addition, we performed pilot studies to determine if electroencephalographic (EEG). recordings might indicate perception of remote happenings even in the absence of correct overt responses. We concentrated on what we consider to be our primary responsibility?to resolve under conditions as unambiguous as possible the basic issue of whether a certain class of para- normal perception phenomena exists. So we conducted our experiments with sufficient control, utilising "visual, acoustic and electrical shielding, to_ensure that all conventional paths of sensory input were blocked: At all times we took measures to prevent sensory leakage and to prevent deception, whether intentional or unintentional. Our goal is not just to catalogue .interesting events, but to uncover patterns of cause-effect relationships that lend them- selves to analysis and hypothesis in the forms with which we are familiar in scientific study. The results presented here constitute a first step towards that goal; we have established under known conditions a data base from which departures as a function of physical and psychological variables can be studied in future work. ? REMOTE PERCEPTION OF GRAPHIC MATERIAL First, we conducted experiments with Mr Uri Geller in which we examined his ability, while located in an electrically shielded room, to reproduce target pictures drawn by experi- menters located at remote locations. Second, we conducted double-blind ' experiments ' with Mr Pat Price, in which we measured his ability to describe remote outdoor scenes many miles from his physical location. Finally, we conducted pre- Declassified and Approved For Release 2014/01/09: CIA-RDP79-00999A000200010006-9 Declassified and Approved For Release 2014/01/09: CIA-RDP79-00999A000200010006-9 C.) Nature Vol. 251 October 18 1974 liminary tests using EEGs, in which subjects were asked to perceive whether a remote light was flashing, and to determine whether a subject could perceive the presence of the light, even if only at a noncognitive level of awareness. In preliminary testing Geller apparently demonstrated an ability to reproduce simple pictures (line drawings) which had been drawn and placed in opaque sealed envelopes which he was not permitted to handle. But since each of the targets was known to at least one experimenter in the room with Geller, it was not possible on the basis of the preliminary testing to discriminate between Geller's direct perception of envelope contents and perception through some mechanism involving the experimenters, whether paranormal or subliminal. So we examined the phenomenon under conditions designed to eliminate all conventional information channels, overt or subliminal. Geller was separated from both the target material and anyone knowledgeable of the material, as in the experiments of ref. 4. In the first part of the study a series of 13 separate drawing ?experiments were carried out over 7 days.--No-experiments are deleted from the results presented here. At the beginning of the experiment either Geller or the experimenters entered a shielded room so that from that time forward Geller was at all times visually, acoustically and electrically ,shielded from personnel and material at the target location. Only following Geller's isolation from the experi- menters was a target chosen and drawn, a procedure designed to eliminate pre-experiment cueing. Furthermore, to eliminate the possibility of pre-experiment target forcing, Geller was kept ignorant as to the identity of the person selecting the target and as to the method of target selection. This was accomplished by the use of three different techniques: (I) pseudo-random technique of opening a dictionary arbitrarily and choosing the first word that could be drawn (Experiments 1-4); (2) targets, blind to experimenters and subject, prepared independently by
