Relationship between digit ratios and aggressive behavior in male undergraduates

目的探讨大学男生指长比与攻击行为的相关性,为相关研究的深入开展提供参考。方法采用修订后攻击问卷,抽取辽宁医学院326名18～23岁大学男生为研究对象,筛查出高攻击行为组23人,其余303人为低攻击行为组,运用直接测量法测定左右手指长。结果大学男生攻击行为与父亲职业、父亲学历、家庭经济条件、教养方式、与父母关系、学习成绩、受欢迎程度均存在明显相关(P值均<0.05)。大学男生左手食指(2D)和环指(4D)明显长于右手(P值均<0.05),左手2D∶3D(中指)和2D∶5D(小指)明显大于右手(P值均<0.05)。高攻击男生左手2D∶3D、右手2D∶4D与身体攻击、言语攻击和攻击总分均存在明显相关(P值均<0.05),右手3D:4D与身体攻击、言语攻击、愤怒和攻击总分均存在明显相关(P值均<0.05)。结论高攻击男生部分指长比与身体攻击、言语攻击及愤怒存在相关。

Objective To explore the relationship between digit ratios and aggressive behavior in male undergraduates, and to provide evidertce for the further study. Methods Totally 326 male undergraduates aged from 18 to 23 years old were surveyed with revised aggression questionnaire. Twenty-three male students were selected as the higher aggressive behavior group, and 303 male were normal group. Measurements were taken from the middle of the basal crease to the tip of the finger. Results Aggressive behavior was significantly related to father＇s work, father＇s educational attainments, family＇s economic condition, parental rearing style, relationship between parents and children, academic performance and popularity （ P 〈 0.05 ）. The left index finger （ 2D ）＆ ring finger （4D） were significantly longer than those of right hand in male undergraduates （ P 〈 0.05 ）. The ratio of 2 D and 3 D and of 2 D and 5 D on left was significantly higher than on right hand in male undergraduates （ P 〈 0.05 ）. In higher aggressive behavior male, 2D： 3D on left and 2D： 4D on right was significantly related to physical aggression, verbal aggression, anger and total aggression（ P 〈 0.05 ）. The ratio of 3 D and 4D on fight was significantly related to physical aggression, verbal aggression, anger and total aggression （ P 〈 0.05 ）.
