InterNiche is well known for its mature code and high-quality Internet protocol software and networking expertise, specifically targeting connected device imple- mentations.
When judging all the mentations from the ganzfeld experiment, the judge (JW) noted that water and birds were, in fact, very common themes in the mentations, even though in many cases, there was no water or birds on any of the four clips in the set to be judged.
Following this explanation, the correspondences between mentations and decoy clips could be viewed as due to clairvoyance, or, for those receivers who later watched all four clips in the used set, as due to precognition.
An independent judge (JW) rated the virtual mentations according to their similarity to the target video clip and three decoys, as the "human receiver" had done with his or her own personal mentation.
The inter-rater reliability between the two judges employed by Roe and Holt (2005) was poor, with a Cohen's kappa of .202, suggesting that the mentations were indeed open to a range of interpretations.
For these analyses we planned to consider only the RNG-generated mentations so as to allow for meaningful comparisons with the studies described above.
RNG mentations will allow each independent judge to identify the target clip to a greater degree than expected by chance.
In both modes, three percipients would be used, and the individual mentations about each site would be combined into a single mentation pertinent to that site, which was to be ranked by an independent judge.
However, Kanthamani and Palmer (1993) described an experiment in which senders were presented with the target image only briefly (ten 1-ms exposures during the sending period) and between exposures were engaged in a PK task so that they might adopt a "subliminal sending strategy." Independent judges' ratings of receivers' mentations gave only two direct hits in 22 trials, which was nonsignificantly below a mean chance expectation of 5.5.
he the thing was on the first two , there wasn't sonically any space for his time around we kind of created ace in its own right to put the extra mentation in."
The latest research looked for sleep-time "mentation" - thoughts, essentially - in a small group of very unusual patients.
Afterward they were shown four target possibilities (all postcard-sized pictures) and they rated each picture as to its similarity to their mentation. Thus in the laboratory experiment participants were helped by strong suggestions about the possibility of precognition.
