BRAUD' ABSTRACT: A formal investigation was conducted in order to determine whether a rela- tively large number of unelected subjects would be able to exert a distant mental influence upon the rate of hemolysis of human red blood cells. For each of 32 subjects, red blood cells in 20 tubes were submitted to osmotic stress (hypotonic saline). The subjects attempted to protect the cells in 10 of the tubes using visualization and intention strategies; the remaining 10 tubes served as noninfluence controls. For each tube, rate of hemolysis was measured photometrically over a 1-minute trial period. Subjects and experimenter were "blind" re- garding critical aspects of the procedure, and subjects and tubes were located in separate rooms in order to eliminate conventional influences. Results indicated that a significantly greater number of subjects than would be expected on the basis of chance alone showed independently significant differences between their "protect" and "control" tubes (p = 1.91 x 10-5). Overall, blood source (i.e., whether the influenced cells were the subject's own cells or those of another person) did not significantly influence the outcome, although there was a trend toward stronger. hitting in the "own blood" condition. Additional analyses of the results were performed by SRI International researchers to determine whether the data were better described by remote action (causal) or by intuitive data sorting (informational) predictions; the results of those mathematical analyses were inconclusive. This research is presented in the context of methodologies for investigating a possible role of psi in self- healing. Laboratory research has indicated that under certain conditions persons are able to psychokinetically influence a variety of biological systems (see r An earlier version of this paper was presented at the 31st annual convention of the Parapsychological Association in Montreal, Canada, August 17-21, 1988.

I am indebted to Rick Berger, Steve Dennis, George Hansen, Scott Hubbard, Kay Mangus, Ed May, Diane Morton, Julie Nixon, Marilyn Schlitz, Helmut Schmidt, Winona Schroeter, and Jessica Utts for their important contributions to various phases of this investigation. This project was supported, in part, by a subcontract from SRI International.

At the Mind Science Foundation (MSF), we have been able to observe successful distant mental influences upon the spatial orien- tation of fish, the locomotor activity of small rodents, and the physiolog- ical activity of another person (Braud, 1978a, 1979; Braud, Davis, & Wood, 1979; Braud & Schlitz, 1983; Schlitz & Braud, 1985). Such findings are consistent with an interpretation of psychic healing in which the healing might be contributed, at least in part, by the healer's conscious or unconscious psychokinetic influence upon the healee's bodily pro- cesses. It is a relatively straightforward matter to design experiments to isolate a possible psi component in one person's healing of another. The healee may be kept blind regarding the timing and nature of a healing attempt, and various isolation and control procedures can be applied. However, it is ordinarily impossible to study the role of psychic functioning in self- healing in vivo using such techniques. The healer is necessarily aware of the timing and nature of self-healing attempts, and therefore the psychic process cannot be isolated from the many nonpsychic factors that can in- fluence healing. We cannot distinguish a psychic effect from the more conventional influences of expectation (the "placebo" effect), changes in emotionality, self-regulation of neural, muscular, and hormonal activities, etc. Fortunately, it may be possible to eliminate the influence of these nonpsychic processes through the use of biological psychokinesis (bio- PK) protocols that have proved useful in the study of distant mental influ- ence. The strategy would involve the selection of some specific biological activity to be targeted psychokinetically and then the removal of the mea- sured biological activity, in space or in time, from the reach of all possible nonpsychic self-influences. Spatial or temporal isolation could be accomplished in three ways: 1. The experimental participant could attempt to influence cells, tissue, or biochemicals that have been freshly removed from his or her body. 2. The participant could attempt to influence his or her own biological activity that had been prerecorded at an earlier time and that had remained unobserved until the subsequent influence attempt; this strategy involves the so-called "time-displaced" or "retro-psychokinesis" design explored by Schmidt (1976, 1981; Schmidt, Morris, & Rudolph, 1986). Another method of removing the target biological activity in time would be to ask participants to attempt to influence their own future activity. In this case, the influence epochs would have to be coded in a way that would elimi- nate the possibility that the participant might remember the desired out- come and consciously or unconsciously self-regulate at the time of the future test in order to bring about the,desired changes. 3. The participant could attempt to influence a particular physiological or biochemical process within his or her body while, at the same time, the activity of a similar, externalized process is monitored to determine whether the latter responds in "resonance" or in "sympathy" with the former.

Psi influence thus becomes a viable component in self-regulation and hence in self-healing. We might even find that persons are psychically able to influence their own cells or activities more readily than they are able to influence the cells or activities of another person. If this is indeed the case, it would suggest that psi's contribution to self-healing may be greater than its contribution to the healing of another person. It would also suggest that more impressive re- sults might be obtained in bio-PK studies if experimenters selected target systems that were more closely associated with the participant-influencers in their experiments. We have conducted numerous bio-PK experiments in which both se- lected and unselected participants were able to alter significantly the ac- tivity of specific biological target systems, mentally and at a distance. In all of those studies, the amount of target system activity in the prescribed direction during a number of influence periods was compared statistically with its activity during an equal number of interspersed control (nonin- fluence) periods. The obtained bio-PK results have been reliable and rela- tively robust. For example, a recent review of all of the MSF's electro- dermal bio-PK experiments conducted to date indicated a z = 4.08, p = .000023, and mean effect size = 0.29 for all 13 experiments combined (Braud & Schlitz, 1989). Experiments could be conducted, using an iden- tical methodology, in which persons attempt to influence their own biolog- ical materials. If Eccles (1977) and others are correct in maintaining that one's mind routinely exerts a true psychokinetic influence upon one's own brain through "cognitive caresses" of the synapses of cortical neurons, then perhaps the most ideal target material would be nervous tissue that had been removed and cultured externally (or cloned). At first, it might appear that such an experiment would not be feasible. However, a study of this type could actually be done with the cooperation of a neurosurgeon. Brain tissue that is removed for medical reasons and that is ordinarily discarded might be artificially cultured and maintained as target material for bio-PK attempts by the patient, following his of her recovery from the operation. Outside of this seemingly science-fictional scenario, the next best target material might be lymphocytes (white blood cells with important roles in the immune process: B-cells, T cells, natural killer cells). Unfortunately, the procedures required for the measurement of these cells or of their bio- logical activities are relatively complex and beyond the capabilities of most psi research facilities. It is noteworthy that several researchers re- cently have reported results of experiments in which their subjects were strikingly successful in self-regulating specific sub-populations of their leukocytes (e.g., neutrophils) using relaxation and imagery techniques (see Braud, 1986; Hall, 1984a, 1984b; Schneider, Smith, & Whitcher, Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 4 Journal of the American Society for Psychical Research 1984). The work of Schneider et al. is especially interesting in view of the accuracy, rapidity, and specificity of the influences that occurred without the provision of conventional sensory feedback. The process appears goal- directed and immediately reminds one of the similar goal-directed nature of psychokinesis. The third best, and logistically the easiest, material with which to work would be osmotically stressed red blood cells. The goal of the experiment would be to protect one's own red blood cells and retard their rate of hemolysis. If red blood cells are maintained in fluids having a salinity similar to that of the blood plasma, the cells survive for long periods. However, if placed in a fluid having a salinity lower than that of the plasma (e.g., in distilled water or in very dilute saline), the corpuscles swell due to the movement of water through their semipermeable mem- branes. Eventually the cells rupture and release their hemoglobin content into the surrounding medium. The rate of hemolysis can be measured using a spectrophotometer with an output to a computer and pen recorder. Light of a given wavelength is passed through a tube of blood cells sus- pended in dilute saline. Intact cells are relatively opaque to the light. As the cells rupture, the solution becomes increasingly transparent. The spec- trophotometer/computer/pen recorder system provides an objective readout of the change in light passage over time, and hence the time course of hemolysis. Rate of hemolysis can be measured during influence trials in which the research participant attempts to mentally retard the he- molytic process, that is, attempts to psychokinetically protect the red blood cells from osmotic injury. These results can be compared with he- molysis rates obtained during interspersed control trials in which no psy- chokinetic attempts are made. We conducted a preliminary experiment of this sort in our laboratory several years ago. In that experiment, involving a single selected subject and a small number of trials, a significant influence of hemolysis rate was observed (Braud, Davis, & Wood, 1979). In the present experiment, we sought to repeat that experiment with many more trials, a large number of unselected subjects, and an improved methodology, in order to test the reproducibility and generality of the finding. Briefly, subjects attempted mentally to retard the rate of hemolysis of osmotically stressed human red blood cells that were isolated from all conventional influences. The sub- jects and the target system were kept in separate rooms. Rate of hemolysis was monitored accurately by a spectrophotometer interfaced by means of an analog-to-digital converter to a microcomputer. The experimenter operating the equipment was blind regarding the scheduling of the influ- ence (protect) versus noninfluence (control) attempts. Half of the subjects worked with their own blood cells, and half worked with cells from an- other person; both experimenter and subject were blind regarding the blood source. The experimental design included features that we hoped would help us determine whether any obtained psi effect might be most parsimoniously interpreted as a true psychokinetic (remote action) effect or, alternatively, as an instance of "intuitive data sorting" (see May, Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Distant Mental Influence of Hemolysis Rate 5 Radin, Hubbard, Humphrey, & Utts, 1985). Prior to the formal experi- ment to be described in detail in this paper, two additional studies were conducted-a pilot study and an "intermediate phase" study. Space limi- tations permit only relatively brief summaries of those two studies. SUMMARY OF THE PILOT PHASE Thirty-two unselected subjects participated in a pilot study designed to explore the new methodology and to determine whether blood source (own blood cells vs. another person's blood cells) was an important factor. An experimental session involved hemolysis measurements for 10 blood tubes. The subject attempted to retard the rate of hemolysis of 5 of these tubes, mentally and at a distance. The remaining 5 tubes served as control tubes that the subject did not attempt to influence. The 5 influence and 5 control tubes were scheduled according to a random sequence that was prepared by a third party and that was unknown to the experimenter who made the hemolysis measurements. Light transmission through each tube (which is proportional to hemolysis) was measured for each second of a 2-minute sampling period; the difference between the mean of the initial 5 seconds and the final 5 seconds of light measurements yielded a change score that served as the hemolysis measure. Following the completion of the experimental session, 10 additional blood-containing tubes were measured for hemolysis rate. It was intended that these 10 measurements would provide additional "nonlocal" baseline data and would also be useful in comparing remote action (RA) versus intuitive data sorting (IDS) predictions of the experimental outcome. Ac- cording to the RA hypothesis, the mean of the 5 "local" control tubes should be equivalent to the mean of the 10 nonlocal baseline tubes, and the mean of the 5 influence tubes should be lower (i.e., in the direction of less hemolysis or greater protection of the cells) than both of the former means. According to the IDS hypothesis, the mean of the local controls should be above, and that of the influence tubes should be below, that of the nonlocal baseline tubes; the grand mean of the 10 tubes for the experi- mental session should not differ from the mean of the 10 nonlocal baseline tubes. An analysis of variance of the hemolysis scores indicated extremely great and highly significant variability among the subjects, but no other significant main effects or interactions. Therefore, significant evidence for a remote influence of the blood cells was not obtained in the pilot study. There was, however, a nonsignificant tendency for a slight "protection" effect in the "another's blood" condition, whereas the opposite effect (i.e., less protection during the influence trials) occurred in the "own blood" condition. The nonlocal baseline measurements were found to be inadequate for their intended purpose because in every case but one the mean percent light transmittance change score for the 10 nonlocal baseline Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789ROO2200620001-9 6 Journal of the American Society for Psychical Research tubes was lower than both experimental sessions means (i.e., consistently lower than both the control and the influence tube means). It was deter- mined that this consistent reduction in hemolysis for the nonlocal baseline tubes (and to a lesser extent, for the tubes later in the experimental ses- sions as well) was due to a progressive change in the blood cells contrib- uted by several environmental factors that increased the "noise" level of the experiments and that included higher apparatus (i.e., spectrophotom- eter tube holder) temperatures during later tests, and increasing exposure of the blood cells to temperature changes, air, and mechanical trauma (i.e., mechanical agitation) during the course of repeated tests of a single blood sample (i.e., multiple tests of the contents of a single Vacutainer blood collection tube). As a result of the pilot sessions themselves, as well as additional tests conducted concurrently with and subsequent to the pilot experiment, the sources of these interfering factors were identified, and steps were devised that could be taken to eliminate or greatly reduce them in the formal study. Temperature changes in the spectrophotometer tube holder were con- trolled through (a) the addition of an external cooling fan to the apparatus, (b) reducing the durations of the hemolysis measurement periods, and (c) turning off the apparatus except when measurements were actually being made. The substitution of a more effective anticoagulant (acid-citrate-dex- trose) for that used in the pilot study (heparin) greatly diminished the ef- fects of progressive exposure to room temperature, air, and mechanical trauma during repeated pipette samplings so that hemolysis rate remained relatively stable over the course of 20 measurements from a given main Vacutainer source tube. When between 20 and 30 samples had been taken from a main Vacutainer tube, this stability began to deteriorate. SUMMARY OF THE INTERMEDIATE PHASE OF SALINITY TESTS Following the completion of the pilot study, salinity tests were con- ducted in order to determine salinity values that might mimic anticipated psi-induced hemolysis rate changes. These tests provided the basis for Monte Carlo analyses that were designed to determine appropriate param- eters for an adequate differential test of the IDS versus RA predictions of psi functioning that was to be conducted in the formal study. A total of 332 hemolysis trials were completed using whole blood samples collected from 10 different persons. For these tests, the "noise- reducing" improvements mentioned above were incorporated. Hypotonic salinity values of 0.425%, 0.429%, 0.434%, 0.442%, and 0.450% (corre- sponding, respectively, to 50%, 50.5%, 51%, 52%, and 53.33% of 0.85% normal physiological saline) were tested. Sampling epochs of 1-minute duration were used, rather than the 2-minute periods of the pilot study. All other procedures were identical to those of the pilot study. These were all, Approved For Release 2000/08/08 : CIA-RDP96-00789ROO2200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Distant Mental Influence of Hemolysis Rate 7 of course, "control" tests in which no subjects attempted to influence the hemolysis process. As anticipated, the "noise-reducing" improvements resulted in the vir- tual elimination of the extreme variability seen in the pilot study and yielded much greater stability (less degradation) of the blood samples. The optimum salinity value for mimicking an anticipated psi-induced reduction of hemolysis rate of approximately 1.0 standard deviation was found to be in the vicinity of 0.429%-0.434% saline (equivalent to 50.5%-51.0% of normal 0.85% physiological saline). Monte Carlo simulation analyses conducted on these salinity data indicated that on the basis of the magni- tudes of hemolysis changes observed in these intermediate phase salinity tests, the use of 2 versus 8 samples (tubes) distributed throughout equiva- lent "psi effort" periods would provide adequate measurements for a dif- ferential test of the IDS versus RA interpretations of any psi effects ob- tained in the formal experiment. Another purpose of these salinity tests was to assure that our spectro- photometric method was actually assessing hemolysis, rather than other possible artifactual time-changing processes that could be confused with hemolysis. A number of tests were performed using identical procedures but with normal 0.85% physiological saline rather than hypotonic saline. No hemolysis should occur with such a solution, and any changes ob- served could be attributed to artifacts. As expected, hemolysis did not occur in these normal saline tests; the photometric readings and curves were completely stable throughout the sampling periods. OVERVIEW OF THE FoRMAL EXPERIMENT On the basis of the findings of the preliminary study, the pilot study, and the intermediate phase experiments, a final protocol for the formal experiment was developed that included the following features: 1. Thirty-two subjects (from the same population and selected in the same manner as in the pilot study) would each participate in one experi- mental session. Hemolysis measurements would be made by the experi- menter, W.G.B. 2. Sixteen subjects would attempt to influence (protect) their own blood cells, and 16 would attempt to influence the cells of another person. Both subject and experimenter would be blind regarding the source of the blood until all 32 sessions had been completed. This "own" versus "other" factor was retained in the formal experiment because of the trend toward different outcomes in those two conditions observed in the pilot study. 3. Blood samples would be collected in Vacutainer tubes containing acid-citrate-dextrose (ACD) anticoagulant and would be refrigerated im- mediately after the blood was drawn. Blood samples would be stored at Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 8 Journal of the American Society for Psychical Research 4?C and would be removed from the refrigerator only briefly, before each hemolysis trial. 4. Hemolysis trials would be conducted between 14 and 42 hours fol- lowing a blood draw. The ACD anticoagulant permits cold storage of blood cells for as long as 3 to 4 weeks with minimal deterioration of red blood cells. 5. The temperature increase of the spectrophotometer would be mini- mized by means of an external cooling fan, the use of shorter sampling epochs, and allowing the apparatus to remain on only during hemolysis measurement periods. 6. A session would consist of four 15-minute periods-two control (C) periods and two protect (P) periods. For half of the subjects, these periods would be scheduled in a CPPC order; for half of the subjects, a PCCP order would be used. This block-counterbalancing design was employed in order to assure that any reasonably linear potential progressive error (such as changes in hemolysis rate due to slight progressive warming of the apparatus) would contribute equally to the two (C and P) conditions and therefore not introduce a systematic bias. Whether a given subject's sequence was CPPC or PCCP would be randomly determined by an asso- ciate (M.S.) through use of the RAND table of random numbers. The experimenter doing the hemolysis measurements would, of course, be blind regarding these sequences. A subject would learn his or her proper sequence by consulting a sealed envelope delivered to the subject after the experimenter's interactions with the subject had been completed and the experimenter had returned to the equipment room. 7. The beginning of each 15-minute period would be signaled by an appropriate number of tones delivered to the subject's headphones. The subject would have been instructed to attempt to mentally decrease the rate of hemolysis of the distant red blood cells during the two 15-minute protect periods. During the two 15-minute control periods, the subject would attempt not to think about the experiment and would allow the cells to hemolyze at their normal, rapid rate. During the two protect periods, the subject would view a projected color slide of healthy, intact red blood cells as an aid to visualization and intention. During the two control pe- riods, the subject would close his or her eyes and think about matters unconnected with the experiment. 8. During each 15-minute period, either two or eight hemolysis tubes (samples) would be measured. Monte Carlo analyses conducted at SRI International indicated that curves derived from 2 versus 8 tubes (samples) would be sufficient for an adequate test of the IDS versus RA interpreta- tions of any obtained psi effect. The subject would be blind regarding the number of tubes being measured during any 15-minute period and would be instructed to apply mental effort as steadily and as consistently as pos- sible throughout the entire 15-minute protect periods. The experimenter would learn whether to measure 2 or 8 hemolysis tubes during each 15- minute period by consulting a sealed envelope delivered to him just before Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789ROO2200620001-9 Distant Mental Influence of Hemolysis Rate 9 the beginning of the measurement session. This random, balanced tube sequence would have been determined earlier by M.S., again using the RAND table of random numbers. 9. Because the subjects must remain blind regarding the number of tubes being measured during each 15-minute period, it would not be pos- sible to provide them with real-time auditory feedback of the progress of hemolysis, as we had hoped to do. Such feedback would provide subjects with information about the number of tubes and would therefore violate the blindness requirement and add a psychological confound to the experi- ment. However, the subject would receive numerical feedback about he- molysis outcomes at the conclusion of the session. 10. The subject's session would be preceded by 8 minutes of tape-re- corded instructions for relaxation and guided imagery, designed to help reduce distractions and focus attention upon the desired goal event-viz., decreased hemolysis during effort (protect) periods. 11. Hemolysis measurements would be accomplished with a procedure identical to that used in the pilot study, with the following exceptions: (a) the recording epochs would be 1 minute rather than 2 minutes in duration, and (b) the subject would not hear tones signaling the beginning and end of each tube measurement (as in the pilot study), but rather would hear tones signaling the beginning of each of the four 15-minute periods. 12. Hemolysis scores would be analyzed in a manner identical to that described in the pilot study. A similar ANOVA would be used to assess the presence of a psi effect. In addition, all hemolysis percent change scores would be normalized for purposes of additional IDS versus RA analyses. Subjects Thirty-two subjects participated in the study. Participants were selected from a pool of normal, healthy individuals and were screened to eliminate those with known allergic or immunological disorders or other illnesses and those currently taking medication (other than oral contraceptives and/ or occasional cold medicines). Twenty-one of the subjects had already participated in the pilot investigation and were asked to participate again because of their familiarity with the procedure. Eleven subjects were first- time participants who substituted for pilot study subjects who were unable to take part in the formal study. The final sample consisted of 17 females and 15 males, ranging in age from 23 to 53 years. Each subject was paid $20 as a token of appreciation for the inconvenience and slight discomfort of donating a blood sample and for participating in the subsequent 11h- hour laboratory session.

An attempt was made to schedule two experimental ses- sions on Tuesday (at 10:00 a.m. and at 2:00 p.m.) and two sessions on Wednesday (at 10:00 a.m. and at 2:00 p.m.). On the Monday evening, the participant was given a two-page written description of the procedure and was asked to read the description at home and become familiar with it. The four blood samples were drawn by a registered nurse.2 The blood collection tubes (Becton Dickinson Vacutainer tubes containing acid- citrate-dextrose anticoagulant) were labeled with the names of the blood donors and were placed in a small refrigerator immediately after the blood draws. The refrigerator was maintained at 4? C throughout the experiment. When all four blood samples had been drawn, the nurse switched the name labels on two of the tubes, using a randomizing schedule that had been prepared ahead of time by an associate of the experimenter (M.S.). This schedule was always kept by the nurse (and a copy kept by M.S.) and was unknown to the experimenter until the study had been completed. The purpose of switching the labels of two tubes was to permit two subjects to attempt to influence their own blood and two to attempt to influence an- other person's blood that week, and to keep the subjects and the experi- menter blind regarding the blood source until all 32 sessions of the study had been completed.3 Following his or her arrival for the experimental session on Tuesday or Wednesday, the experimenter showed the subject the equipment at the target site, emphasized the spectrophotometer tube holder in which the target tubes later would be placed sequentially, and then escorted the sub- ject to the distant subject room, located in another part of the building (see floor plan in the Figure). The subject sat in a comfortable armchair and was told that shortly after the experimenter left the subject's room, an assistant would slip an envelope under the subject's door. The subject was 2 The order in which the subjects' blood was drawn, and hence their subject numbers for the blood source factor (i.e., whether they subsequently attempted to influence their own or another person's blood) was determined by the alphabetical sequence of the surnames of the four subjects who assembled on any given Monday evening blood-drawing session. 3 On one Monday evening, a last-minute cancellation by a subject resulted in three, rather than the usual four, blood draws that evening. The next week, the subject who had cancelled for the previous week appeared; there also appeared an additional subject who was not ex- pected, resulting in six subjects that evening. For the two subjects who did not conform to the schedule that evening, blood tubes were inadvertently switched, when they should not have been. This resulted in a total of 18 subjects in the "another's blood" condition and 14 subjects in the "own blood" condition.

(The 32 period-sequence enve- lopes had been prepared beforehand by M.S. using the RAND table of random numbers and a private algorithm. Throughout the experiment, the envelopes remained hidden from the experimenter. M.S. retained a copy of the period sequences for the 32 envelopes.) During each of the two 15-minute control periods, the subject was to attempt to keep her or his mind off of the experiment and to think of other matters; if she or he could not help thinking about the experiment, the subject was asked to imagine hemolysis proceeding at its normal, rapid rate. During each of two 15- minute protect periods, the subject was to attempt to mentally retard the rate of hemolysis of the red blood cells in the tubes.for that period using any of the mental strategies described on the instruction sheet. The experi- menter demonstrated a slide projector that could be used by the subject during the two protect periods. The 35 mm color slide depicted healthy, intact red blood cells, and it was included as a helpful aid to the subject's visualization of the desired goal. The subject was told that the beginning of each period would be signaled by an appropriate number of tones (one for Period 1, two for Period 2, and so on) presented through headphones.

The exercise was accompanied by low-volume, ambient music and ocean sounds. Low-volume ambient music was also presented through the sub- ject's headphones throughout the four periods of the experiment and was interrupted only for the four-period signaling tone presentations. The con- clusion of the experiment was indicated to the subject by the cessation of the music. At that time, the subject was to sign and date his or her period sequence sheet and then be escorted back to the apparatus room by an assistant. The experimenter returned to the apparatus room, where the equipment had already been readied for use. Just before entering this room and closing the door, he indicated to an assistant that the experiment was about to begin. The assistant gave him a sealed envelope that contained infor- mation about his 2- versus 8-tube sequence for that session, and then de- livered another sealed envelope to the subject; this latter envelope con- tained the subject's protect versus control period sequence for that session. The experimenter started the audiotape that presented the preliminary ex- ercises to the subject. He then conducted the 20 hemolysis measurements for the session. From his point of view, there were also four 15-minute periods of measurements; two of the periods (indicated on a sheet within his envelope) were to involve measurements of two tubes, and two of the periods were to involve measurements of eight tubes. This number of measurements factor was included to provide data for a differential test of the IDS and RA predictions of psi performance (see below). The subjects remained blind regarding the tube number schedule for the session. Each of 20 identical 10-m1 glass spectroscope tubes had been filled be- forehand with 6.0 ml of 0.425% saline, and these had been kept in the refrigerator at 4? C. The saline for all tubes for all sessions came from the same stock solution of 0.85% normal physiological saline, purchased in 20-liter quantity from Fisher Scientific Supply Company and diluted with distilled water to 0.425% by the experimenter before the study began. This use of solution from the same stock eliminated variability that other- wise might have been contributed by that factor. The experimenter re- moved the main blood collection (Vacutainer) tube bearing that subject's name from the refrigerator, inverted the tube eight times in order to assure a homogeneous suspension of its blood cells, opened the tube, and placed it in a test tube rack on the equipment table. He then removed the first of the hypotonic saline tubes from the refrigerator and allowed it to stand at room temperature and warm slightly so that moisture from the warmer room-temperature air no longer condensed on the tube after the latter was wiped with tissue. He placed the now frost-free saline tube into the holder of the spectrophotometer and adjusted the controls of the device so that a digital reading of precisely 100.0% light transmission was obtained for Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Distant Mental Influence of Hemolysis Rate 13 this blank tube. He pressed a computer keyboard key to initiate a subrou- tine that signaled the subject in the distant room that a 15-minute period was about to begin. He next removed the tube from the holder and added to the tube 100 ?l of whole blood from the main Vacutainer tube. He quickly stoppered the saline tube with a rubber stopper, inverted the tube twice to assure homogeneity of its contents, and quickly replaced the tube in the spectrophotometer holder. When the holder cover was closed, the chart recorder pen moved to indicate minimal light transmittance; at the point of greatest excursion of the pen, the experimenter pressed a key- board key to initiate the 1-minute sampling epoch for that tube. The Vacu- tainer blood collection tube was then returned to the refrigerator, and the next hypotonic saline tube was placed in the test tube holder so that it might warm slightly for the next trial. The precise timing of all procedural events was controlled by the experimenter through the use of several pro- cedural cues and by means of extreme stereotypy of responding. Throughout the sampling epoch, the chart recorder and the digital readout of the spectrophotometer were shielded' so that they could not be observed by the experimenter. This was done in order to eliminate immediate feed- back to the experimenter in the hope that this might reduce the latter's own psi contribution to the experimental outcome. Percent light transmittance measures at a wavelength of 660 mp (an absorbance minimum for hemoglobin) relative to the blank tube con- taining saline alone were taken by means of a Sequoia-Turner Model 390 spectrophotometer with digital and chart recorder readouts. The spectro- photometer provided an analog output that varied from 0 to 1.0 v DC and was linearly related to percent light transmittance (with 0 v DC = 0% T and 1.0 v DC = 100% T). This output was increased by a factor of 10 by means of a differential amplifier, and the resulting 0 to 10.0 v DC signal was fed into an analog-to-digital converter installed in an IBM PC-XT compatible computer. The A/D converter (CGRS Microtech PC DIADAC 1) uses an industry standard AD 574A 12-bit A/D chip with 0.0024 volt accuracy and 35 ?sec conversion speed. A software program was written that sampled the A/D converter at the end of each second of the 1-minute trial period. Thus, the system automatically provided 60 measurements of the time course of hemolysis (i.e., percent transmittance) during each 1- minute trial. The 60 values were written to a floppy disk file and were also printed out at the end of the trial. In addition to this digital data collection, an analog chart record was obtained for each trial (using a Markson Model 1202 pen recorder). At the end of the 1-minute sampling epoch, the experimenter removed the tube from the holder and began his preparations for the remainder of the trials. Approximately one minute elapsed between trials. If a period called for the measurement of two tubes, those two tubes were measured at the middle of the 15-minute period, that is, at times corresponding to the measurement of tubes 4 and 5 of an eight-tube period.

The comple- tion of the hemolysis measurements for the 20 tubes of an experimental session required one hour. When the 20th and final tube had been measured, and the results had been printed, the experimenter notified his assistant that the session was over. While the assistant went to the subject's room, the experimenter made photocopies of the data sheets and of his tube-number schedule. When the assistant returned with the subject, the assistant photocopied the subject's control/protect period sequence sheet. The assistant and the ex- perimenter then exchanged copies of their respective sequence sheets and data printouts. These duplicate records were filed for safekeeping by the assistant and by the experimenter. The experimenter and the subject then went to the experimenter's of- fice, and the subject described the techniques used to attempt to influence the blood cells. After this interview, the experimenter calculated the re- sults for the experimental session and provided the subject with informa- tion about the session outcome. This information consisted of verbal and numerical feedback about the hemolysis rates for the 20 tubes. The exper- imenter thanked the subject for his or her participation, and the subject left the laboratory. RESULTS When all 32 experimental sessions had been completed, the blood source information was decoded so that a determination could be made of which subjects attempted to influence their own blood and which at- tempted to influence blood from another person. For each session, change scores were calculated for each of the 20 blood sample tubes (trials). For each tube (trial), the mean of the initial five AID converter values was subtracted from the mean of the final five AID converter values. This change score represented the change in percent light transmittance from the first 5 seconds to the last 5 seconds of the 1-minute trial and provided a quantitative measure of the rate of hemolysis for a specific blood sample tube. For each subject, change scores were available for 10 control tubes and 10 influence (protect) tubes; for each tube condition, scores were available for either 2- or 8-tube measurements during each 15-minute pe- riod. Using these change scores, a three-factor analysis of variance was used to test the major hypotheses of the study. In this ANOVA, the three factors were: blood Source (own vs. another's, between); Subjects, random and nested under Source; and Condition (protect vs. control, within). The three experimental questions explored in this formal study were the following: 1. Would the rate of hemolysis (change scores) for the protect tubes differ from that for the control tubes? Such an effect would be indicated, in the absence of a significant Condition X Subjects interaction, by a Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Approved For Release 2000/08/08 : CIA-RDP96-00789R002200620001-9 Distant Mental Influence of Hemolysis Rate 15 significant Condition main effect in the ANOVA. Should the Condition X Subjects interaction effect prove significant, the condition effect would be examined separately in each of the individual subjects, using appropriate within-subject error estimates. 2. Would the degree of influence of hemolysis rate differ for the two blood sources (own cells vs. another's cells)? Such an effect would be indicated by a significant interaction of the Source and Condition factors of the ANOVA. 3. Would results for the two-tube measuring periods differ from those for the eight-tube measuring periods, and would the function describing this two- versus eight-tube effect match more closely the RA or the IDS prediction? For the statistical tests, any probability value found to be less than or equal to .05 would be deemed significant. The summary table for the ANOVA is given in Table 1, and means and standard deviations for the various groups and conditions are given in Table 2. The main effects for Condition and Source did not reach signifi- cance, nor did the Source X Condition interaction. However, the main effect for Subjects and the Condition x Subjects interaction were highly significant. The former effect, of course, indicates significant variability in outcome among the 32 subjects of the experiment. The significant Con- dition X Subjects interaction indicates that the effect of Condition (protect vs. control) differed from subject to subject; therefore, an interpretation of the Condition main effect was inappropriate, and individual subject by subject condition comparisons were called for. These individual comparisons were made by means of matched t tests, computed for each of the 32 subjects. These were calculated by comparing the hemolysis (change) scores for a subject's 10 protect tubes with the scores for his or her 10 control tubes. Individual t tests were calculated using separate estimates of variance, instead of using the combined esti- mate of error variance from the ANOVA, because of the wide spread among the variances across subjects. The t scores for the individual sub- jects are presented in Table 3. The independently significant subjects (i.e., those with Itl [181 > 2.101, p < .05, two-tailed) are indicated by as- Table 1 ANALYSIS of VARIANCE SUMMARY TABLE Source (own vs another's) 1 0.3480 0.3480 0.001 .981 Condition (protect vs control) 1 2.2278 2.2278 0.461 .503 Subjects 30 18078.7369 602.6247 297.626
