【摘要】：Kosfeld等研究证实由下丘脑分泌、脑垂体释放的神经肽催产素能增强人们对他人的信任感,能增强人们对他人观点的从众效应,从而增强人们的社会凝聚力。本实验研究首次使用真实社会情景实验范式,探究了在日常生活中的社会性问题的情景下,催产素鼻喷剂是否会影响人们对男性专家身份的建议者、女性专家身份的建议者——心理咨询师,或男性非专家身份的建议者、女性非专家身份的建议者——园林设计师,对他们所给予的解决这些社会性情景问题的选择性建议的接受率,同时我们也探究了催产素鼻喷剂对人们所能感知到的对专家身份建议者的面孔或非专家身份建议者的面孔以及新面孔的喜欢程度和信任感的影响,与此同时我们也研究了催产素鼻喷剂的效应是否能长时间维持。本研究的实验设计为双盲设计,被试间设计,对照实验设计。实验中我们邀请了男性和女性被试,总共160名被试随机使用了24IU的催产素鼻喷剂或安慰剂,休息45分钟后进行决策任务实验。实验结果表明与使用安慰剂鼻喷剂的被试相比,催产素能显著性增强人们对女性心理咨询师所给予的建议的接受率,但对男性心理咨询师、男性园林设计师以及女性园林设计师所给予的建议的接受率没有显著性影响。并且根据人们对建议者面孔和新面孔的喜欢程度和信任感评分结果显示与另外三位建议者相比女性心理咨询师为最具信任感的个人,但相对于安慰剂组,催产素对人们所能感知到的外显性喜欢程度评分和信任感评分没有显著性影响。同时实验结果表明催产素能显著性提高人们对女性心理咨询师所给予的建议的接受率的效应无法维持一周的时间,人们所接受的大部分的建议均返回到他们最初的选择。由此推断催产素能增强人们对最具信任感的个人的观点的从众效应,但无法增强人们所能外显感知到的对最具信任感个人的信任感或喜欢程度,因此催产素能短暂的提升人们对最具信任感的个人所给予的建议的接受率。总而言之,在日常生活中,催产素能通过增强人们对最具有信任感个人所给予的建议的从众效应从而增强人们的社会性凝聚力。
[Abstract]:Kosfeld and other studies have confirmed that oxytocin released from hypothalamus and pituitary can enhance people's trust in others, enhance their conformity to other people's views, and thus enhance their social cohesion. In this study, we first used the real-society situational paradigm to explore whether oxytocin nasal spray would influence people's advice on male expert status in situations of social problems in daily life. Female expert status counselors, or male non-expert status counselors, female non-expert identity counselors, landscape designers, The acceptance rate of their selective recommendations to address these social scenarios, We also looked at the effects of oxytocin nasal spray on the perceived level of interest and trust in the faces of or non-expert status counselors, as well as in new faces. At the same time, we studied whether oxytocin nasal spray effects can be maintained for a long time. The experimental design of this study is double-blind design, inter-test design and controlled experimental design. A total of 160 subjects were randomly assigned to use oxytocin nasal spray or placebo from 24IU for 45 minutes to conduct a decision-making task experiment. The results showed that oxytocin significantly increased the rate of acceptance of the advice given to female counsellors, but to male counsellors, compared with those who took a placebo nasal spray. There was no significant effect on the acceptance rate of advice given by male and female landscape architects. And women counselors were the most trusted individuals compared to the three other counselors, but compared to the placebo group, according to the people's preference and trust ratings for the face of the proponent and the new face. Oxytocin had no significant effect on the perceived scores of explicit liking and trust. The results also showed that oxytocin could significantly improve the acceptance rate of the advice given by female counsellors for a week, and most of the advice people accepted returned to their initial choice. It is inferred that oxytocin enhances the herd effect on the most trusted individuals, but does not increase the perceived level of trust or interest in the most trusted individuals. Oxytocin therefore temporarily increases the acceptance rate of advice given by the most trusted individuals. In general, oxytocin enhances social cohesion in daily life by enhancing the herd effect of advice given by the most trusted individuals.
