Development different

Studies for individual
Raine- BA
Damasio et al -BD
Freuds theory
Studies for development
Dabbs et al
Hill and hurtado-E
Brain activation explain
Specific parts of the brain have specific functions (LOF)
Influence how we behave qnd reacts ( frontal lobe - impulse control amygdala- threat perception)
Under activity - over activity
Raine et al
Brain activation
41 murders who pleaded NGRI had been compared to controls matched on gender age and ethnicity
And measured there brain activity using a pet scan 32 mins after radioactive tracer was injected into them ^ activity > amygdala
¡ activity in > frontal lobe brain does influence aggression
Brain damage study explain
Phineas gage got into an accident and got tamping iron shots through his head this lead to damage to left and right frontal lobe > more aggression
Damasio eg all
Damage to both left and right frontal lobe caused a defect in rational decision making and reasoning and impulse control
Explaining his sudden change higher aggressive behaviour
Freud explain
Ppl motives arr driven by drives of eros and thanatos and manifested in the unconscious I’d
Undeveloped ego > unable to control I’d urges > more aggressive
Overdevelped superego> more judgmental persona > sees themselves as a failure > aggression towards themselves
Strength of freud
Explains hot blooded and cold blooded aggression in ppl
Hot blooded aggression- impulsive > satisfies the Id
Cold blooded aggression > planned out schemed > ego controls Id
Hormones explain
Exposure to Testosterone increase aggression
If someone is exposed during development they would be more aggressive
Explains why males are more aggressive than females
Dabbs at el
Tested the saliva of male prisoners
And found that there was high levels of testosterone in their saliva for the ppts that committed more violent crimes
Suggested that hormones can influence aggression
Evolution explain
Best suited for survival will survive
Most likely to reproduce an pass on advantageous allele down
Aggression is a tool for dominance
Aggressive genes - low maoa genes
Aggression prevents infidelity and straying
Buss mating Guarding techniques
Hill and hurtado
High aggression was linked to high social status in tribal communities in South America > more access to food and more chances of reproducing w mate
Supports evolutionary theory that aggression promotes survival and passes on of genes
