Approved For Release 20=08/11: CIA-RDP9M017192RVN7G066b6UJbSk an eigenvalue of gamma = -1/3 (RIP 1982, 165-168). RNG1 uses the thermal noise pulses of a p-n transition in such a way that every pulse contributes to the production of the Markoff chain. Since due to equation (4) pragmatic information is the product of novelty E and confirmation B, the same amount of pragmatic informa- tion can be expressed either as much novelty and less confirmation or vice versa. However, if the total amount of pragmatic informa- tion is limited it follows immediately that events containing much novelty E cannot occur very often, which would mean very much confirmation B. For instance, if the "observers" in an RSPK case would "expect" more confirmation B of the focus system for a spe- cific "surprising" phenomenon x, such that the product E(x) * B(x) would exceed the product I = A * R, the phenomenon may produce a displacement in such a way that something unexpected hap- pens for which E(x') * B(x') = A * R holds. From this we can see that the model is even able to give a natural explanation of the re- markable "elusiveness" of RSPK phenomena. A MULTIVARIATE PK EXPERIMENT WITH UNIDIRECTIONAL CORRELATED RNGS Walter von Lucadou (University of Utrecht). Present Address: Hildastrasse 64, D-7800 Freiburg i. Br. , West Germany The experiment should be conceived as a conceptual replica- tion of an experimental program which was performed by the author and collaborators during 1979 and 1985 at the Freiburg University (ZP, 1986, 170-206). A further aim of the experiment is to test several theoretical predictions of the model of pragmatic information (MPI) (see pp. 18-22). The main issue of the experiment is to find (significant) nonlocal correlations between independent sets of psychological and physical variables. Such correlations can also be regarded as a PK effect. Experimental Design The experiment is a statistical PK experiment with a parallel design: About 300 self-selected subjects each performed 8 runs, with each run containing 996 trials of a binary random sequence produced by two different but correlated random sources (RNG1 and RNG2). The display is an optical and acoustical one. During the eight runs per session, RNG1 and RNG2 are ex- changed systematically in a doubleblind way. Every second run is a nonfeedback run with the same RNG conditions as the previous Both RNGs produce binary Markoff chains (0,1) with an er- gotic expectation value of P = 1/2, a variance of s = /(n/12) and With RNG2 only those pulses of RNG1 contribute that surmount a certain level of pulse amplitude. This level and the generation rate (counting time) of the RNG can be chosen arbitrarily. The level was set to 150 units and the counting time to 40 units in most runs. This implies that a run needs about two minutes. With - these parameters the count rate of RNG1 is about 1600 counts/unit and 1000 counts/unit for RNG2. This procedure provides a unidirectional correlation between RNG1 and RNG2 because RNG2 can only produce a count if RNG1 produces one surmounting the given level of amplitude. The prob- ability for a count in RNG2 is therefore about 1000/1600. The Markoff chains are used as the PK target. They represent the momentary pulse rate of the random source (p-n transition). A "1" means that the momentary pulse rate is increasing while a "0" indicates it is decreasing. Thus, a comparison of the two RNGs allows us to find out whether PK changes either the rate of the random pulses or its amplitude or even both (see Hypothesis 3). The Markoff chains produced by RNG1 and RNG2, respec- tively, are not directly connected to the display. A special pseudo- random sequence (difference set: 83, 41, 20) with a defined auto correlation function decides the direction of the display, thus de- fining a "display function" D. This display function is the same for all runs including the nonfeedback runs. The psychological variables are measured by the "Amsterdamse Biographische Vragenlijst" (ABV) and two versions of the VROPSOM. The ABV and VROPSOM-M are filled out by the subject before the experiment and VROPSOM-O after the experiment. The ABV is dis- played item by item on the computer screen and the subject gives the answer by pushing a button. Before starting each run the subject has to give a confidence score on his or her "PK abilities." The Markoff chains of both RNGs of all runs and the answers on the ABV questionnaire are binarily coded and stored on diskette. After every session day a safety copy of the diskette is made. The experimenter is kept blind to the results until the end of the whole study. Moreover, he is not present in the room with the subject during the experimental session. The subjects get trial-by-trial feedback on the display (colored computer screen with sound) and an additional verbal feedback on the computer screen after each feedback run. The subject is not informed about the nonfeedback runs that take place in the pause between the feedback runs. The whole session takes about 45 minutes. A standardized instruction is given by the experimenter.
