neural and hormonal

Question 1

neural meaning

Answer 1

• relates to the nervous system and brain only

Question 2

limbic system meaning

Answer 2

• subcortical structures in the brain believed to be involved in regulating human emotions, including aggression

Question 3

serotonin meaning

Answer 3

• neurotransmitter with inhibitory effects throughout the brain, has a key role in aggression

Question 4

testosterone meaning

Answer 4

• hormone produced mainly in male testes, associated with aggressiveness

Question 5

limbic system

Answer 5

• coordinates behaviour that satirises emotional and motivational urges
• amygdala and hippocampus are associated with aggression, are apart of the limbic system

Question 6

amygdala

Answer 6

• evaluates sensory info, prompts a response to environmental threats/ challenges
• if certain areas are stimulated , animals respond aggressively, so removing the areas of the amygdala eliminates the aggressive response

Question 7

kluver and bucy

Answer 7

• destruction of amygdala in a monkey who was dominant in a social group, caused it to lose its dominant place in the group

Question 8

hippocampus

Answer 8

• involved in forming long term memories
• if an animal encounters another animal that its been attacked by before, they’ll respond aggressively
• impaired functioning stops nervous system putting stimuli into context
• may create innapropiate aggressive response

Question 9

  -

Question 10

dolan et al (testoesterone)

Answer 10

• positive correlations between testosterone levels and aggressive behaviours in a sample of male offenders in max security hospitla

Question 11

whats the difference between neural and hormonal

Answer 11

neural = brain structures ( limbic system) + neural transmitters (serotonin)

hormonal - test only

Question 12

amygdala support

Answer 12

• role supported by research into human aggression

e- e.g pardini carried out longitudinal study of 56 male p , with different histories of violence

e- MRI scans shows that people with smaller amygdala = higher lvls of aggression and violence even after controlling for confounding variables

l- suggests that amygdala plays important role in evaluating sensory info’s importance and a smaller amygdala can’t do this aswell, makes aggression more likely
