Proactive aggression
Proactive aggression
Cold-blooded, calculated behaviour aimed at specific goals
Reactive aggression
Reactive aggression
Hot-blooded, impulsive response with anger & physiological arousal
Amygdala's main function in aggression
Amygdala's main function in aggression
Threat detection centre evaluating stimuli & determining responses
Serotonin's effect on brain activity
Serotonin's effect on brain activity
Inhibitory - slows neuronal activity & promotes self-control
Testosterone production sites
Testosterone production sites
Primarily in male testes, small amounts in female ovaries
Biosocial model of status (BMoS)
Biosocial model of status (BMoS)
Testosterone fluctuates with status competition, affects aggression
Dual-hormone hypothesis
Dual-hormone hypothesis
Testosterone promotes aggression only when cortisol is low
Orbitofrontal cortex (OFC) role
Orbitofrontal cortex (OFC) role
Self-control, impulse regulation & aggressive behaviour inhibition
Virkkunen et al. finding on 5-HIAA
Virkkunen et al. finding on 5-HIAA
Impulsive offenders had lower 5-HIAA (serotonin breakdown product)
Main research limitation for neural/hormonal aggression studies
Main research limitation for neural/hormonal aggression studies
Correlational - can't establish causation due to ethical constraints
