Aggression Flashcards
Neural explanation
brain structures and neurotransmitter levels. Limbic system controls emotional response
Hypothalamus - controls ANS (if damaged…)
Amygdala - controls emotional response (damage can lead to overreaction)
Serotonin - higher aggression (no inhibition)
Neural - evaluation
ultimatum/Fmri
PA – benzodiazepines
Correlational research = inconclusive.
Scientific methods
Hormonal explanation
high testosterone associated with high aggression.
T acts with receptors in brain
Affects neural transmission and amount of neurotransmitters at serotonergic synapse. Low S = higher aggression
Hormonal - evaluation
Dolan found correlation
biological determinism
MAOA gene
gene controls enzyme low of this to (warrior gene)
Only men – on X (cancelled out in women)
Mop up excess neurotransmitters (abnormal leads to aggression)
Genetic - evaluation
Brunner Dutch family (but another explanation – SLT)
Legal system – free will and determinism
Objective method
Socially sensitive – blame family.
Evolutionary explanation
Adaptive
Status, territory, mates, resources and dominance
Strong jawline and forehead - attractive
Men fight for risk of cuckolding
Mate retention strategies
Direct guarding – give me your phone
Negative Inducement – insulting or threatening
Evolutionary - evaluation
domestic abuse risk.
Correlation between suspicion of cheating and spousal violence
Can explain gender difference – Campbell but soldiers. Kung san tribe shows it isn’t inevitable
Ethological
Animals aggressive because it is adaptive and is for survival. Fight for territory, status, dominance mates, resource
Ritualism
Fighting in pack – not real, just for practice
Innate releasing mechanism
Cue to be aggressive
Fixed action pattern
Automatic reaction
Ethological - evaluation
Stickleback Red fish
Haka and Eskimos support the fake fighting
PA – zookeepers
Extrapolation. Humans have different reasons
Deindividuation
Feel less responsibility
