Abstract [eng] The aim of dissertation study was to investigate the influence on the ratings of affective images based on the levels of healthy women‘s sex steroid hormone and to compare the responses of central and autonomic nervous system. The present dissertation is based on carried out three studies. Based on the results of the first study, it concluded that International Affective Picture System (IAPS) can be used for emotion studies in Lithuanian female. The second study demonstrated a significant positive relationship between progesterone level and valence ratings of unpleasant images. The third study showed that the menstrual cycle phase is a significant factor for the subjective rating of affective images. Unpleasant images are more arousing than pleasant for women in the luteal phase. The correlation analysis confirms that women sensitivity to pleasant and unpleasant stimuli in luteal phase could be influenced by progesterone levels. Mean late positive potential amplitude (LPP) depends on the content of affective stimulus, but does not depend on the levels of sex steroid hormone. Phasic heart rate response depends on the content of affective stimulus, but does not depend on the levels of sex steroid hormone. In conclusion, the findings indicate the effect of menstrual cycle phase on subjective affective image ratings in healthy women reporting regular menstrual cycle.
