Abstract

Two experiments were conducted in this study. First, the relation of reaction time (RT), and respiration rate to contingent negative variation (CNV) amplitude during a relaxation by the self-regulation method (SRM) were examined in 9 healthy subjects who had practiced SRM for 5 weeks. CNV amplitudes were reduced during SRM in both CNVs associated with the fastest and slowest RTs. The respiration rate decreased during SRM compared to before and after SRM condition. The CNV amplitude decreased along with the respiration rate. Secondly, the effect of the voluntarily change in the respiration rate on CNV amplitude was studied in 7 subjects who had not mastered SRM. The CNV amplitude also decreased with the respiration rate. These results suggest that the CNV amplitude reduction during SRM could be associated with the effects of the respiration rate. but not with RT.
