The Selfield: Optimizing Precognition Research

We report an exploratory forced-choice precognition study based on a  protocol that utilized an immersive audiovisual environment to induce a  psi-conducive state in participants. Our objective was to assess whether  this optimization setup would help produce significant psi results with  an unselected population. We also sought to assess whether  trial-by-trial feedback would produce superior scoring to no-feedback  trials. For each trial, participants selected an opaque graphical sphere  that they felt contained a facial image, as opposed to being empty.  After selection, the program randomly determined whether the sphere  would be empty or not, and whether feedback would be shown. A preset  total of 3000 binary choice trials were collected from 82 participants.  Each participant contributed either 1 or 2 20-trial series, based on  preset scoring criteria. The total hit rate of successful trials was  50.1%, close to expectation under the null hypothesis of no psi effect.  Hit rates for feedback and no-feedback trials were in the predicted  direction (51.0% vs. 48.6%). A post-hoc analysis showed that hit rates  for feedback trials increased over the 20-trial series, suggesting that  participants may have progressively found a mental strategy for improved  scoring. Additionally, a subgroup of 26 experienced meditators had a  hit rate of 52.1%, a result consistent with previous literature that  suggests that meditators are particularly good participants for psi  research.
