Olds and Milner
Supports effects of drugs including recreational drugs on CNS (used rats).
1 of 31
Wolosker
Supports neurotransmitter theory, found glial cells to have a role.
2 of 31
Jovanic
Supports neurotransmitters affecting brain when looking at woment with PMDD.
3 of 31
Duke
Disputes neurotransmitters being involved in brain. Smaller than expected inverse relationship between serotonin and aggression.
4 of 31
Straiker and Mackie
Shows recreational drugs affect the brain using hippocampal neurons from mice.
5 of 31
Pertwee
Shows brain has more than one reward pathway so recreational drugs aren't that bad.
6 of 31
Heinz
Found link between increased alcohol intake and aggression due to serotonin transmission in amygdala.
7 of 31
Andy and Velamati
Supports role of limbic system in aggression, as cats have aggressive seizures when it is stimulated.
8 of 31
Downer
Supports amygdala and evolution in aggression because monkeys are passive without it.
9 of 31
Raine
Supports brain structure causing aggression as NGRIs have abnormal brain.
10 of 31
Sperry
Supports role of brain structure in aggression, particularly with corpus callosum.
11 of 31
Swantje
Supports role of amygdala in aggression. Aggressive women have a lower volume of amygdala by 16%.
12 of 31
Phineas Gage
Case study that supports role of prefrontal cortex in aggression.
13 of 31
King and Whitman
Case studies that support amygdala's role in aggression.
14 of 31
Adelson
Shows that brain shows homonal stress response to aggression triggering hypothalamus.
15 of 31
Trainor
Mice can't be generalised to humans, but their hypothalamus and limbic system is similar.
16 of 31
Marsh
Low connectivity between amygdala and prefrontal cortex is present with aggression.
17 of 31
Buss and Shackleton
Supports evolution in aggression. Men use debasement and intersexual threats when threatened.
18 of 31
Lorenz
Supports evolution as geece imprint on adult and adult is aggressive to protect babies.
19 of 31
Wynne-Edwards
Group selection is to keep populations in check.
20 of 31
Batra
Used the term 'eusocial' to decribe nesting behaviour in bees as they cooperate.
21 of 31
Dobash
Supports evolution as sexual jealousy leads to aggression.
22 of 31
Dollard
Frustration aggression theory: when source of frustration can't be challenged, displacement happens.
23 of 31
Dabbs
Supports role of hormones in aggression. 10/11 prisoners have high testosterone levels.
24 of 31
Barzman
Supports role of hormones in aggression. Boys in psychiatric hospital are aggressive with more cortisol.
25 of 31
Chang
Supports role of hormones in aggression. Fish are more aggressive with more testosterone and cortisol.
26 of 31
Wagner
Supports role of hormones in aggression. Castrated mice are less aggressive.
27 of 31
Mazure and Booth
Men with more testosterone are more likely to be delinquent.
28 of 31
Montoya
Testosterone/cortisol balance predicts impulsivity and instrumental aggression.
29 of 31
Fromm
Adds to psychodynamic theory. Two types of aggression, one when threatened and one when achieving goals.
30 of 31
Sluyter
Although mice and humans share 90% of genes, they can't be generalised.
