Abstract
The first objective of this experiment was to explore the possibility that the pattern of PK scoring might be different between relatively high and low alpha coherence states. Subjects were selected for their ability to produce alpha coherence. Alpha coherence required that both right and left EEG channels met selected amplitude and frequency limits simultaneously and that they were within 12.5% of the same frequency. The results of the t-tests as well as the F test for the total variance between PK run scores for high alpha coherence runs and low alpha coherence runs did not reach significance.
This study also explored the possible difference in variance of a subject's PK scores as related to the magnitude of directional shift in physiological state measure. For this study, shifts of state were inferred by the amount of change generated in each of the monitored physiological measures, EEG,EMG, BSR, and Skin Temperature. The relationship between the magnitude of directional shift and success in the PK task, nonrandom operation of the computer's random number generator was explored.
Overall PK variance differences between shifts in physiological state were nonsignificant, as tested by calculating correlation coeficients. The degree of PK run score variance did not appear connected to the shifts in physiologiccal state.
The possible correlation between cognitive style, as measured by Richardson's Verbalizer Visualizer Questionnaire, and performance on the PK task was also explored. No correlation was indicated by the results.
