- Neural and Hormonal Mechanisms
- Neurotransmitters
- Serotonin
- Low levels = aggression
- Dopamine
- High levels = aggression
- Serotonin
- 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
- Androgen Stimulation in the early days after birth causes changes in the neural system
- Conner and Levine (1969) suggests developmental factors
- Associated with aggression
- Found in humans and non-human animals
- Men with high levels of testosterone do not necessarily become aggressive
- Athletic Prowess
- Dabbs et al (1987) criminals with high levels of testosterone had a history of violent crimes
- Gender bias, focused on men - what about women? studies shows increased testosterone makes women nicer in some situations.
- Klinesmith et al (2006) found that environmental stimuli, such as guns, increase aggression and thus increases testosterone
- Sapolsky (1997) aggressive behaviour elevates testosterone levels
- 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
- Lowers neurotransmitte, serotonin
- 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
- Castration
- 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
- Appears to have a mediating affect on aggression-related hormones
- Testosterone
- Neurotransmitters
- Certain individuals have increased genetic disposition to aggression
- Evolution and Human
- Evolutionary Theory
- Infidelity and Jealousy
- Group Displays
- Social Psychology
- Decrease in Aggression
- Hormone therapy restores aggression to pre-castration levels
