通过对赫蒂特大学学生进行横截面研究,评估侵略性和数字比率之间的关系
1Faculty of Arts and Sciences, Department of Anthropology, Division of Physical Anthropology, Hitit University, Çorum, Turkey.
概括
第二到第四位数的比率 (2D:4D) 显示了土耳其大学生中性别特异性与攻击性亚型的关联. 虽然较短的数字与女性的攻击性较低相关,但较高的2D:4D比率与男性的愤怒和敌意相关.
科学领域:
- 行为内分泌学行为内分泌学.
- 人类行为研究研究人类行为研究.
- 心理学科学 心理学科学
背景情况:
- 第二到第四位数比率 (2D:4D) 是产前丸激素暴露的公认生物标志物.
- 之前的研究将2D:4D比率与侵略性联系在一起,观察到由生物和环境因素影响的性别特异性变化.
研究的目的:
- 研究2D:4D比率与土耳其大学生中的侵略水平 (包括亚型) 之间的关系.
- 探索2D:4D比率与侵略性行为之间的关系中的潜在性别差异.
主要方法:
- 一项涉及Hitit大学203名本科生 (108名女性,95名男性) 的横截面研究.
- 数字长度 (2D和4D) 使用数字口径仪进行测量.
- 使用Buss-Perry侵略问卷 (BPAQ) 评估攻击程度;统计分析包括曼-惠特尼U,克鲁斯卡尔-瓦利斯和斯皮尔曼相关性.
主要成果:
- 在女性中,右手较短的2D和4D长度与身体和口头攻击有较弱的负相关性.
- 在男性中,右手较高的2D:4D比率和左手的2D:4D比率与愤怒和敌意子表弱正相关.
- 在右侧的2D:4D比率和男性的总攻击性得分之间发现了弱正相关性.
结论:
- 数字比率没有显示出显著的性二态,但其与侵略的关联在性别之间有所不同.
- 女性显示较短的手指长度和侵略性之间的负相关性,而男性显示较高的2D:4D比率和愤怒/敌意之间的正相关性.
- 尽管具有统计学意义,但相对应系数较弱表明这些发现的解释要谨慎.

01:47Aggression
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression.
