A single subject who had a history of multiple PSI experiences was given 23 sessions of 40 symbol-guessing trials per session over a 4-mo. period. Accuracy scores were correlated with the geomagnetic activity (Ap) on the days of the testing. A moderately strong negative correlation was found between the scores and the geomagnetic activity. These results are compatible with those reported for subjective psi experiences.
