Abstract

Reports an error in the original article by N. S. Don et al (Journal of Parapsychology, 1995[Dec], Vol 59[4], 357-380). Figure 1 on page 359 was improperly rotated on the page. The figure and legend are reproduced properly. Used signal processing analysis to examine forced-choice ESP data from 6 experiments. A cross correlation of guesses with targets revealed presence of periodic maxima. Most matches between guesses and targets were in dusters that recurred regularly and periodically throughout the range of displacements. Fourier analyses of cross correlations were performed to quantify harmonic patterns, and power maxima wee compared to Monte Carlo simulations. In linear and circular correlation analyses of grouped data from selected Ss, the mean power was significant. Post hoc analyses of grouped data from 52 unselected Ss revealed that only Ss with visual cognitive styles guessing high-!imagery targets had significant or near-significant correlation waves. Psi may be an oscillatory correlational field dependent on or interacting with mental factors and target characteristics and capable of organizing information in contextually meaningful ways.
