Summary
50 males, 17 and 18 years of age, and their natural parents were given the Blacky Defense Preference Inventory to determine if there are commonalities of defense preferences within families and within sex groups.
The results tended to support the hypothesis that male adolescents manifest defense preferences more similar to those of their father than to nonrelated adult males but failed to support a comparable hypothesis concerning the adolescent's similarity of defense preferences to his mother versus nonrelated adult females. The adolescent males did not reveal defense preferences more similar to those of their father than of their mother nor were sex differences in defense preferences observed. An additional finding suggested that the adult males are more heterogeneous in their defense preferences than are adult females.
