Neurophysiological Approach to Examining Knowledge/Belief in the Prayer of an Untrained Person: A Case Study.

An adult female (22 years) of Christian orthodox religion was examined during the silent Lord's prayer, the most common, short prayer, with the aim of possible differentiation between belief and knowledge in her experience, analyzing the behavior of subgroups of theta and beta cerebral EEG rhythms, which occur through constant and occasional activation of cerebral regions. The participant was not trained in reading the prayer to herself or other people. EEG examination was performed by Nihon Kohden Corporation, EEG-1200-K Neurofax apparatus, in the monopolar longitudinal montage in the system of 10/20 electrodes aimed at determining the peak frequency value of each exploratory site. The method of result analysis was based on connecting cerebral regions into networks of 3 or more members according to identical peak frequency value, which was observed within subgroups of theta and beta frequencies and analyzed through a proximity index and continuity and discontinuity of activation during the observed period. Out of the definite observation sample of 3 s from each subperiods (beginning, middle and end), a window of 2 s was moving from the beginning till end of the period with 200-ms time lag. This resulted in six subsamples for each electrode and for each experimental situation (resting state, situation of prayer). Stable and unstable activity of the regions was assessed within subgroups via cartographic formulas equivalent to the states which subgroups of theta and beta imply in psychophysiological sense. The results indicated that through participant's inner dialogue-monologue there are elements of both knowledge and belief, and that this phenomenon is possible considering insufficiently specific circumstances of the experiment and the participant herself, such as her relatively young age and insufficient practice of praying. The paper discusses the types of connections between regions which imply knowledge and those related to belief according to our understanding and regarding findings in literature.
