An experiment tested the pathways through which alcohol expectancies and intoxication influenced men's self-reported sexual aggression intentions during an unprotected sexual encounter. After a questionnaire session, male social drinkers (N = 124) were randomly assigned to either an alcohol condition (target peak BAC = .08%) or a control condition. Upon completion of beverage consumption, parti...

Different approaches have been used to classify children as relationally aggressive, physically aggressive, or both relationally and physically aggressive (co-occurring aggression). The goal of the current study (N = 164, 50.9% boys, Mage = 47.75 months, SD = 7.37) was to test a bifactor model of aggression, which allows for aggression to be assessed dimensionally, and postulates a co-occurring...

After pair-bonding, male prairie voles (Microtus ochrogaster) display aggression toward novel females but not toward their female partner. Here we show that this selective aggression in pair-bonded male prairie voles is associated with increased release of vasopressin (AVP) in the anterior hypothalamus (AH). Pharmacological activation of AVP-V1a receptors (V1aR) in the AH induced selective aggr...

BACKGROUND Neurochemical studies have pointed to a modulatory role in human aggression for a number of central neurotransmitters; some (e.g., serotonin) appear to play an inhibitory role, while others (e.g., vasopressin) appear to play a facilitator role in the modulation of aggression. While recent animal studies of neuropeptide Y (NPY) have suggested a facilitator role for central NPY in the ...

We examined the roles of sensation seeking, risk taking, and moral reasoning in the development of reactive and proactive aggression. Data were drawn from a multiethnic, longitudinal study of children from Switzerland (N = 1,571; assessed annually over 6 years; 7-years-old at Time 1). At all six time points, teachers reported children’s reactive and proactive aggression via questionnaire. Child...
