In this study we investigated the effects of state and trait aspects of self-focused attention on genital and subjective sexual arousal of sexually functional, healthy women during presentation of audiovisual erotic stimuli. Psychophysiological sexual response was measured as vaginal pulse amplitude using a vaginal photoplethysmograph. Experiential aspects of sexual arousal were measured both during stimulus presentation and retrospectively after stimulus offset. Trait level of sexual self-focus was measured with the Sexual Self-Consciousness Scale. State self-focus was induced by switching on a TV camera that pointed at the participant's face and upper torso. A manipulation check revealed that both groups experienced equally elevated levels of self-focused attention of their physical appearance. Induction of state self-focus per se did not affect genital responses, but an interaction effect of self-focus and participants' level of trait sexual self-focus was revealed. Compared with women with low scores on this trait, women with high scores exhibited smaller genital responses when state self-focus was induced. Both groups did not differ when no self-focus was induced. Increase of state self-focus did not affect subjective sexual arousal, but participants with a high level of trait sexual self-focus reported stronger subjective arousal, compared with those with low trait level. The results were discussed with reference to previous work in this field. Some implications for treatment of sexual arousal disorder were discussed.
在本研究中,我们调查了在呈现视听色情刺激期间,自我关注的状态和特质方面对性功能正常、健康女性的生殖器及主观性唤起的影响。使用阴道光电容积描记器测量心理生理性性反应,以阴道脉搏振幅作为指标。在刺激呈现期间及刺激结束后进行回顾性测量性唤起的体验方面。使用性自我意识量表测量性自我关注的特质水平。通过打开指向参与者面部和上半身的电视摄像机来诱导状态自我关注。一项操纵检查显示,两组在对自身外貌的自我关注水平上均同样升高。状态自我关注的诱导本身并未影响生殖器反应,但揭示了自我关注与参与者特质性自我关注水平之间的交互作用。与该特质得分低的女性相比,特质得分高的女性在诱导状态自我关注时生殖器反应较小。在未诱导自我关注时,两组没有差异。状态自我关注的增加并未影响主观性唤起,但与特质水平低的参与者相比,特质性自我关注水平高的参与者报告的主观性唤起更强。结合该领域以前的研究对结果进行了讨论。还讨论了对性唤起障碍治疗的一些启示。
