Butovskaya M., Burkova V., Mabulla A. Sex Differences in 2D:4D Ratio, Aggression and Conflict Resolution in African children and adolescents: A Cross-Cultural Study

Butovskaya M., Burkova V., Mabulla A. Sex Differences in 2D:4D Ratio, Aggression and Conflict Resolution in African children and adolescents: A Cross-Cultural Study // Journal of Aggression, Conflict and Peace Research, Vol.1, issue 1, 2010, pp.17-31.

ABSTRACT

This study was conducted on children and adolescents from the three tribal cultures from Northern Tanzania: the Hadza, the Datoga and the Iraqw. The comparative data on aggression and conflict management skills were measured at Endomaga Boarding School, Lake Eyasi, Mangola in Northern Tanzania, in 2005-2006. The final sample included 219 children, ranging from 7 to 20 years of age. No sex differences were found in self-ratings or frequency of occurrence of physical, verbal and indirect aggression in Iraqw children and adolescents, or in self-ratings in Hadza. Hadza boys reported a higher occurrence of physical and indirect aggression during the previous week compared to girls. No differences between the sexes were found in constructive conflict resolution and third-party interventions practiced by Iraqw and Datoga children and self-ratings in Hadza. Hadza boys reported a higher frequency of constructive conflict resolution and third-party interventions compared to girls. Significant sexual dimorphism on the 2D:4D ratio was found for our African sample. A significant negative correlation between the right hand 2D:4D ratio and ratings on physical aggression was found for the girls. The girls with the lowest finger index estimated themselves as more verbally aggressive, compared to girls with a medium 2D:4D ratio.

KEYWORDS

Gender (sex) differences; physical aggression; verbal aggression; indirect aggression; constructive conflict resolution; third-party intervention; consolation; socialisation strategies; 2D:4D ratio.
