Аннотация:Despite 50 years of research, there is still no common understanding of neurophysiological processes underlying meditation practice since the data obtained are often quite contradictory. For overcoming these difficulties, the literature suggests paying more attention to describing the type of meditation, practitioners’ experience, and other subjective factors (for example, discomfort from electrophysiological equipment or presented stimuli) that can influence the meditation process. In this article, we tried to consider these methodological recommendations and developed a special structured interview to take these factors into account. The results showed that neither field studies (investigation of meditation in conditions as close to natural as possible), nor the study of monks of the same tradition, from the same monasteries, having the same experience in meditation, does not guarantee that sufficiently homogeneous groups of subjects can be formed. A detailed analysis of the proposed structured interview may be necessary to research meditation’s influence on brain mechanisms.
