This precognition study builds on previous research suggesting that free-response protocols with subject-optimization procedures produce higher psi-scores than protocols with no such procedures. Our study aimed to assess the value of optimisation procedures when coupled with a forced-choice protocol, involving multiple trials per session. A second objective was to assess whether trial-by-trial feedback improves scoring over no-feedback conditions. A pre-set total of 3000 binary choice trials were collected over a 7-week period, from 82 participants, including 26 experienced meditation practitioners. Each participant contributed 20 or 40 trials, based on pre-set scoring criteria. The task was set in an immersive environment coupled with a display of spheres emerging out of an animated starfield. For each trial, subjects had to guess which spheres contained an image; the program would then randomly determine whether or not it indeed contained the image, and whether or not feedback would be shown.

期刊介绍:
The Journal of Parapsychology is published quarterly in March, June, September, and December by the Parapsychology Press, a subsidiary of the Foundation for Research on the Nature of Man. The Journal is devoted mainly to original reports of experimental research in parapsychology. It also publishes research reviews, theoretical and methodological articles that are closely linked to the empirical findings in the field, book reviews, news, comments, letters and abstracts.
