[The age-related features of influence biofeedback training on efficiency of functional state voluntary regulation in
Abstract:
The aim of the study was to assess an impact of biofeedback training (5 sessions) onto the voluntary regulation of the brain functional state (relaxation) in two groups of children of 7-8 and 9-10 years old. EEG alpha-band spectral coherence and skin resistance were measured during pre-relaxation, relaxation and post-relaxation phases before and after training. Short-term memory test was used to evaluate behavioral changes in functional state regulation before and after training. The group of children of 9-10 y.o. was the only group that showed any significant relaxation-related changes of spectral coherence in alpha-band after training. Besides, that group showed a significant post-relaxation improvement in short-term memory volume. We found a number of individual psychophysiological indices that influenced an efficiency of the biofeedback training.
