Autoganzfeld II: an attempted replication of the PRL ganzfeld research.
We report the results of an attempt to replicate the ganzfeld-ESP findings of Charles Honorton and his colleagues at the Psychophysical Research Laboratories. Two series of 50 first-time or novice participants and one series of 51 first-timers defined as emotionally close comprised the replication...

Alexander, Cheryl H. su: Extrasensory perception Parapsychology sug: subj: Extrasensory perception Parapsychology ab: We report the results of an attempt to replicate the ganzfeld-ESP findings of Charles Honorton and his colleagues at the Psychophysical Research Laboratories. Two series of 50 first-time or novice participants and one series of 51 first-timers defined as emotionally close comprised the replication data set. Additionally, one series of 50 clairvoyant (no sender) sessions were done along with 8 general pilot sessions. The experiments used much of the same equipment and the same procedure used by PRL researchers. The replication series yielded a direct hit rate of 26.5% (ESπ =.52), which failed to confirm the PRL findings. As expected, the emotionally close series produced a hit rate of 37.3%, which was significantly above chance (ESπ = .64, p =.035). All sessions combined (N= 209) resulted in a nonsignificant hit rate of 25.8%. The replication series exhibited a notable decline in scoring following an interim report of this work in 1995. None of the correlates of successful performance found in prior research were significantly replicated in this study. An expected negative correlation with geomagnetic activity was found at a suggestive level.
