In Weiskrantz study, they lesioned the amygdala in one group. What did they lesion in the other group of monkeys?
Nothing
The PFC
The hippocampus
A different area of the temporal lobe
What was the primary finding from lesioning the amygdala in Weiskrantz's study?
The monkeys became aggressive.
The monkeys showed a lack of fear and became tame.
The monkeys' memory was decreased.
The monkeys died.
A human study that shows similar conclusions to Weiskrantz study is....
HM's case study by Milner and Scoville
KF's case study
SM's case study by Feinstein et al.
Luby et al.'s study on poverty and the brain
How long did Rosenzweig and Bennett keep their rats in different cages before they were euthanized?
2-3 weeks
30-60 days
1-2 years
6 months
Which of the following was NOT in the enriched cage condition in Rosenzweig and Bennett's study?
They received maze training
They had a range of toys to play with
They had other rats in the cage with them
They had sugar in their water and their food
What happened to the brains of Rosenzweig and Bennett's rats?
They had more acetylcholine receptors
Brain weight increased 7-10%
Synapses increase 20%
All of these options
Which of the following was NOT a condition in Albert et al,'s study.
Sham castration
Castration with testosterone tubes inserted later
Castration with empty tubes re-inserted
Castration with amygdala lesioning
Castration
What happened to the alpha status of the castrated male rats in Albert et al.'s study?
They maintained their alpha status
They lost their position and submissive males become alphas
Neither
True or false...increasing testosterone through tubes AFTER castration decreased aggression in the castrated alpha male rats in Albert et al's study.
True
False (aggression was increased after testosterone replacement)
False (there was no change)
How old does a rat or mouse have to be before it can reproduce?
About two weeks old
About two months old
About two years old
About two days old
For how many generations of rats did Van Oortmerssen and Bakker selectively breed their rats?
2
5
11
20
A short attack latency means a rat is...
More aggressive
Less aggressive
The name of the experimental test that is used to measure aggression in rats.
The resident-intruder paradigm
The minimal group paradigm
The home-invasion paradigm
Selective breeding
What was the heritability of aggression in Van Oortmerssen and Bakker's study?
0.2 (20%)
0.3 (30%)
0.5 (50%)
0.9 (90%)
Which of the following was NOT a result in Mosienko's study?
TPH2 knockouts attacked 6 times faster than the control group
The TPH2 gene increased aggression MORE than the MAOA gene
TPH2 knockouts attacked for 7 times as long than the control group
100% of the TPH2 knockouts attacked within 5 mins of the resident-intruder test (compared to 22% in control group)
What will knocking out the TPH2 gene do to serotonin levels?
We don't know
Increase it
Decrease it
It won't affect it - the TPH2 gene will affect testosterone
