Marina L. Butovskaya, Valentina Burkova, Audax Mabulla / Валентина Буркова
Аннотация This study was conducted on children and adolescents from three tribal cultures from Northern Tanzania: the Hadza, the Datoga and the Iraqw. The comparative data on aggression and conflict management skills were measured in boarding school of Endomaga, Lake Eyasi, Mangola, Northern Tanzania in 2005 - 2006. The final sample included 219 children, ranged from 7 to 20 years. No sex differences were obtained in self-ratings or frequencies of occurrences of physical, verbal and indirect aggression in Iraqw children and adolescents as well as on self-ratings in Hadza. Hadza boys reported higher occurrence of physical and indirect aggression during last week compared to girls. No sex differences were found in constructive conflict resolution and third-party interventions practiced by Iraqw and Datoga children and self-ratings in Hadza. Hadza boys reported the 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. The significant negative correlation between the right hand 2D:4D ratio and ratings on physical aggression was found for the girls. The girls with a lowest finger index estimated themselves as more verbally aggressive compared to girls with medium 2D:4D ratio.
