【摘要】：動物研究顯示,雌激素調(diào)節(jié)條件性恐懼習得和消退,但是,人類的性激素對條件性恐懼習得和消退的影響還不太清楚。因此,本研究以大學生為研究對象,考察女性不同生理周期對條件性情境恐懼的習得和消退的影響。20名經(jīng)前期和20名經(jīng)期女被試暴露于3種情境下:無厭惡刺激情境(N)、可預測情境(P)和不可預測情境(U),預測此3種情境下是否出現(xiàn)厭惡刺激。以在線索條件下和無線索條件下對厭惡刺激的主觀預期值為因變量。研究結果顯示:在習得階段,經(jīng)期女性在P情境下的條件性線索恐懼的主觀預期值高于經(jīng)前期女性;經(jīng)前期女性在3種情境下的條件性情境恐懼的主觀預期值都高于經(jīng)期女性,但只在N情境和P情境,與經(jīng)期女性相比,經(jīng)前期女性對厭惡刺激的主觀預期值存在顯著差異。在消退階段,與經(jīng)期女性相比,經(jīng)前期女性在3種情境下的條件性情境恐懼的主觀預期值更高,且經(jīng)前期女性對厭惡刺激的主觀預期值在N情境和P情境顯著高于經(jīng)期女性。該結果顯示,經(jīng)前期女性對條件性情境恐懼易習得難消退,表明此生理階段的性激素影響大腦的情緒調(diào)節(jié)功能,從而影響條件性情境恐懼。
[Abstract]:Animal studies have shown that estrogen regulates the acquisition and extinction of conditioned fear, but the effects of human sex hormones on conditioned fear acquisition and extinction are unclear. Therefore, this study investigated the effects of different physiological cycles on the acquisition and extinction of conditioned situational fear among college students. 20 premenstrual and 20 menopausal female subjects were exposed to three situations: no aversion stimulus situation (N), Predictive scenario (P) and unpredictable situational (U), predict whether aversion stimuli occur in these three situations. The dependent variable is the subjective expected value of aversion stimulus under cues and without cues. The results showed that: in the acquisition stage, the subjective expectation of fear of conditional cues in menstrual women was higher than that in premenstrual women; The subjective expected values of fear in premenstrual women in three situations were higher than those in menstrual women, but only in N and P situations. Compared with women in menstrual period, there were significant differences in subjective expectations of aversion stimuli among premenstrual women. At the stage of regression, the subjective expectation value of conditional situational fear of premenstrual women was higher than that of menstrual women, and the subjective expectation value of premenstrual women to aversion stimulus was significantly higher than that of menstrual women in N situation and P situation. The results showed that the fear of conditioned situation was easy to be learned and dissipated in the early stage, which indicated that the sex hormone in this physiological stage affected the emotional regulation function of the brain, thus affecting the fear of conditional situation.
