A Study of Factors Affecting the Variability in Emotion-related Psychophysiological Responses

정서생리반응의 변산성에 영향을 주는 요인에 관한 연구

Korean constitutional type(Sasang Chejil) was considered with anxiety level and personality type in order variability frequently encountered in EEG research. Sasang Chejil type seems a very important factor to be controled to minimize the variabilty since Sasang Cheji subgroups showed distinct differences in EEG relative power ao more recording sites and frequency bands than the subgroups of anxiety level and personality type, well-reconized variability-contribution factors. It is likely that Tae-Eum Chejil type is predispositioned to be more relaxed and feel happier and less unhappy than So-Yang type since the former showed greater alpha relative powers and left-hemisphere activations at both of the resting and emotional states.
