广西汉族和壮族大学生指长比与攻击行为的相关性

目的:探讨广西汉族和壮族大学生指长比与攻击行为的相关性,为预防大学生攻击行为的发生提供一定的参考。方法:随机选取416例身体健康的广西汉族和壮族大学生(汉族182例,壮族234例)为研究对象。在知情同意的条件下,采用直接测量法测量左右手2D、3D、4D和5D指长,并用攻击行为问卷对研究对象进行调查。按民族和性别分组,计算左右手指长比2D:3D、2D:4D、2D:5D、3D:4D、3D:5D和4D:5D,探讨左右手各指长比与攻击行为的相关性。结果:汉族男生右2D:4D与敌对呈正直线相关。汉族女生左2D:3D与愤怒、敌对和攻击总分呈正直线相关,左2D:4D与敌对呈正直线相关,左3D:5D与身体攻击、右3D:5D与身体攻击和攻击总分、左4D:5D与身体攻击、右4D:5D与身体攻击和攻击总分均呈负直线相关。壮族女生右2D:3D与敌对和攻击总分呈正直线相关,右3D:5D与敌对呈负直线相关。结论:部分指长比对预防广西汉族大学生和广西壮族女大学生攻击行为的发生可能具有一定的参考意义。

Relationship between digit ratio and aggressive behavior of college students of Han and Zhuang nationality in Guangxi

Objective:To study the relationship between digit ratio and aggressive behavior of college students of Han and Zhuang nationality in Guangxi and to provide reference for preventing aggressive behaviors of college students.Methods:The digit lengths of the 2D-5D of left and right hands of 416 healthy Han and Zhuang college students in Guangxi were measured directly with their informed consent.All the participants were required to finish the aggression questionnaire.The individuals were allocated to 4 groups according to nationality and sex.The mean values of 2D ∶ 3D,2D ∶ 4D,2D ∶ 5D,3D ∶ 4D,3D ∶ 5D,4D ∶ 5D digit length ratios of all groups were calculated.The relationship between digit ratio and aggressive behavior of the 4 groups was studied.Results:There was a positive linear correlation between the right 2D ∶ 4D ratio and hostility in male Han group.There was a positive linear correlation between the left 2D ∶ 3D ratio and anger,hostility and aggression in female Han group and the linear correlation between the left 2D ∶ 4D ratio and hostility was also positive.There was a negative linear correlation between the left 3D ∶ 5D ratio and physical aggression in female Han group,and negative linear correlation was also found between the right 3D ∶ 5D ratio and physical aggression and aggression,between the left 4D ∶ 5D ratio and physical aggression,between the right 4D ∶ 5D ratio and physical aggression and aggression.There was a positive linear correlation between the right 2D ∶ 3D ratio and hostility and aggression,and a negative linear correlation between the right 3D ∶ 5D ratio and hostility in female Zhuang group.Conclusion:Some digit ratios may serve as reference for preventing aggressive behaviors of Han and Zhuang college students except the Zhuang males in Guangxi.
