【摘要】：激情作为爱情成分中最易发生变化且最不易控制的成分,在亲密关系研究中十分关键。目前国内外对激情的研究多为考察其神经机制或对亲密关系的影响,较少考察激情唤醒和程度是否存在人格(如强化敏感性)差异。强化敏感性,指个体在面对强化刺激物时所表现出的反应性,影响个体行为、情绪以及动机等的改变趋势和程度。这一理论在心理病理学、成瘾行为及人事组织领域应用广泛,但在两性亲密关系方面的影响却有待探索。已有研究表明恋人间的奖惩性互动对于亲密关系的发展甚为重要,对于刺激信息不同的奖惩认知偏向或将引发情绪状态的区别。针对以往研究的存在的问题与局限,本研究主要针对以下几点内容进行探索:(1)个体强化敏感性对两性亲密关系激情及恋爱满意度影响;(2)激情唤醒的脑机制及生理机制;(3)不同强化敏感性个体激情唤醒的神经生理激活模式差异。本研究对以上问题的探讨分为自我报告和神经生理实验两部分:研究一:探究强化敏感性人格中的奖励敏感性(Sensitivity to Reward,SR)与惩罚敏感性(Sensitivity to Punishment,SP)对恋爱满意度及激情度是否存在影响,采用问卷法对550位处于恋爱中的大学生情侣进行调查,对其强化敏感性、激情度以及亲密关系满意度进行量化,并分析讨论。结果显示,SR对激情度有正向预测作用;SP对恋爱满意度有负向预测作用;此外,性别与激情度和恋爱满意度均显著相关,男性除SP外,其他各项分数均显著高于女性。但男、女性之间是否具有普遍的强化敏感性人格差异,或男性在自我报告上相比女性具有更强烈的社会赞许性倾向,将在研究二中进一步进行探索。经研究一结果发现SR与激情度联系更密切,而SP与激情度相关不显著,故研究二中仅考虑SR对激情的作用机制。研究二:为探究强化敏感性人格中的SR对两性亲密关系激情度是否存在神经生理层面的影响,采用fNIRS技术联合多导生理记录仪监测不同SR被试在观看不同人物照片并回忆相应事件时大脑HbO浓度及多项生理指标变化。结果表明,在高、低SR条件下,个体在激情唤醒时的脑区激活存在模式与程度上的差异,同时这种差异受性别因素影响;不同唤醒条件存在不同的生理反应模式,但个体SR高低对此无显著影响。
[Abstract]:Passion is the most changeable and difficult to control component of love, which is very important in the study of intimate relationship. At present, most of the researches on passion at home and abroad are to investigate its neural mechanism or influence on intimate relationship. Less to investigate the emotional arousal and the degree of personality (such as reinforcement sensitivity) differences. Enhanced sensitivity, refers to the individual in the face of the reinforcement of stimuli to show the responsiveness, affect individual behavior. The change trend and degree of emotion and motivation. This theory is widely used in the field of psychopathology, addictive behavior and personnel organization. However, the impact of sexual intimacy needs to be explored. Previous studies have shown that rewarding and punishing interactions between lovers are important for the development of intimate relationships. According to the existing problems and limitations of previous studies, the cognitive bias of different rewards and punishments or the difference of emotional state will be caused by different stimulative information. This study is mainly aimed at the following points: 1) the influence of individual enhancement sensitivity on the intimate relationship passion and love satisfaction of both sexes; 2) brain mechanism and physiological mechanism of arousal of passion; 3). The neurophysiological activation patterns of individual arousal of passion with different intensities and sensitivities are different. In this study, the above questions are divided into two parts: self report and neurophysiological experiment. Explore the reward sensitivity in the Enhancement of sensitive Personality (. Sensitivity to Reward. S) and the sensitivity to punishment (SP) had an effect on the degree of love satisfaction and passion. The questionnaire was used to investigate 550 college students in love, to quantify their sensitivity, passion and intimate relationship satisfaction, and to analyze and discuss the results. SR can positively predict the degree of passion. Sp had a negative predictive effect on love satisfaction. In addition, gender and passion and love satisfaction were significantly correlated, except SP, the other scores were significantly higher than that of women. Or men have a stronger social approval tendency than women in self-reporting, and will explore further in the second study. One study found that SR was more closely related to passion. However, SP had no significant correlation with the degree of passion. Therefore, in the second study, we only consider the mechanism of SR on passion. In order to explore whether SR in the sensitive personality has neurophysiological effect on the passion degree of intimate relationship between the two sexes. The changes of HbO concentration and several physiological indexes in the brain of different SR subjects were monitored by using fNIRS technique and multi-channel physiological recorder when they were watching photos of different characters and recalling the corresponding events. The results showed that the changes were higher than those in the control group. Under the condition of low SR, there were differences in pattern and degree of brain activation during arousal of passion, and the difference was affected by sex factors. Different arousal conditions had different physiological response patterns, but individual SR had no significant effect on it.
