So, what is clearly needed is some form of baseline on which the correspondences between the receiver mentation and the target content can be compared.
The problem with this method is that in traditional ganzfeld experiments, the mentation is usually recorded only on an ordinary tape recorder, making it difficult to synchronize the mentation with the target clip during the judgment phase and with each of the decoy clips as though the decoy had been the target.
At exactly the same moment, the computer starts recording the receiver's mentation. The receiver's mentation can be heard in real time by the sender.
In addition to these alterations in protocol, we planned to manipulate the source of randomness by which mentation statements were selected in order to explore the effects of target lability, following Braud (e.g., 1981, 1994), who has talked at length and persuasively about its importance in the occurrence of PK.
The participants' subjective ratings of the degree of correspondence between the mentation and their experiences and thoughts while sending information about the target video clip will be higher for live RNG statements than for pseudorandom statements, which will be higher than for random number table statements.
For each condition of each trial, the independent judges compared the 8 statements to the four video clips for that trial, giving each clip a confidence rating (based on similarity between the clip and the mentation) between 0 and 99%.
In this paper we report on a second aspect of that study which concerns the performance of an RNG that served as a virtual receiver during the ganzfeld session, generating an alternative mentation to be rated by independent judges.
At the end of the sending period, the 20 statements that had been selected most often formed the mentation. In the event of any ties at the cutoff point of 20 the first selected was automatically taken.
In comparing the performance of the sender with that of the REG, it may have been preferable to have both mentations assessed by the independentjudge so as to make the outcomes more comparable.
The discrepancy between the results of holistic judgements of REG mentations by an independent judge and the outcome of the atomistic analysis could indicate that any apparent success of the REG mentation is actually due to psion the part of the judge.
Similarly, in the previous studies there was no indication that participants tended to guess the target according to what it would have been had the stock market figures been used from the day of their mentation rather than from a few days later.
