      • Genes
      • Neural and Hormonal Mechanisms
        • Neurotransmitters
          • Serotonin
            • Low levels = aggression
          • Dopamine
            • High levels = aggression
        • Hormonal
          • Testosterone
            • Castration
              • Decrease in Aggression
              • Hormone therapy restores aggression to pre-castration levels
              • Castration at birth shows decreased levels of aggression in adults
                • Androgen Stimulation in the early days after birth causes changes in the neural system
                  • Edwards (1968) suggests that testosterone masculinises androgen-sensitive neural circuits
              • Conner and Levine (1969) suggests developmental factors
            • Associated with aggression
              • Found in humans and non-human animals

              • Lindman et al (1987) those who act aggressively drunk have higher testosterone levels
            • Influential during two periods of life; 1)'Critical Time Period' , 2)Adulthood
              • 1) Acts to sensitise neural brain circuits
              • 2) Testosterone peak during puberty, corresponding peak in male aggression
            • Those with more testosterone are more likelyto be competitive and assertive
              • Aggression in certain situations are just a by-product
            • Acts on serotonergic synapses
              • Lowers neurotransmitte, serotonin
                • Research incicates as being involved with heightened levels of aggressiveness
            • Male hormone found in low levels amounst females
              • Low levels of testosterone found in aggressive females
            • Albert et al (1998) Reported there was a lot of research which doesn't show a significant relationship between aggression and testosterone
          • Cortisol
            • Appears to have a mediating affect on aggression-related hormones
              • Dabbs et al (1991)
            • McBurnett et al (2000) low cortisol levels resulted in antisocial acts and aggression
      • Certain individuals have increased genetic disposition to aggression
    • Evolution and Human
      • Evolutionary Theory
      • Infidelity and Jealousy
      • Group Displays
