What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Men from a culture of honor often use physical aggression in response to threats as a way of restoring lost honor. These threats can range from being called an offensive name to someone flirting with their romantic partner. However, cultures of honor form to protect society against threats. Once society no longer needs protection, cultures of honor dissipate. In three studies, the protective qualities of a culture of honor were examined by comparing aggression levels when romantically attached men were threatened to when their significant other was threatened. Study 1 (N=114) consisted of hypothetical scenarios while Study 2 (N=260) and …
