What hormones has been correlated with aggression and violence? Give a study that relates to this.

Testosterone

Many! (Cohen, Radke, Albert )

What neurotransmitter has been correlated with antisocial, impulsive, aggressive and violent behaviour? Give a study that investigates this.

Serotonin

(Passamonti)

100
What are the names of the cells in the brain?
Neurons

Which psychologists wanted to know how different environments would affect brain development in rats? 

Rosenzweig & Bennett

200

What happened in Albert et al's study after they castrated the alpha male rats?

Their aggression decreased and they lost their "alpha" status.

200

Low serotonin levels decrease what region's ability to control the amygdala. 

The prefrontal cortex (and the connection of the PFC with the amygdala)

200

What part of the brain is our "emotional centre"? Give a study that investigates this.

The amygdala

(Many! Feinstein, Passamonti)

200

Describe the procedure in the Iowa Gambling Task.  Describe the "pattern" and results.

17 healthy controls/ 8 patients with lesions on vmPFC.

4 deck of cards. Participants select a card from one of the decks. They repeat 100 times. They win or lose based on their decisions. They don't know, but 2 decks have high initial reward but long term risk. Whereas 2 decks have low initial risk and low reward.

Result: healthy participants were able to see the "pattern" about about 20-30 trials.  Participants with vmPFC were not.

Which psychologists wanted to investigate the role of the hippocampus in the role of spatial memory?

Maguire (2000)

300
According to Goetz et al and Radke et al, what part of the brain does testosterone affect when viewing angry faces?
The amygdala
300
What is the amino acid that helps to build serotonin in the brain?
Tryptophan
300
What part of our brain is associated with regulating our impulsive behaviour?
Prefrontal cortex (or the frontal lobe)
300
what system is slow, deliberate and requires conscious effort?
system two
300

Which psychologist wanted to know the correlation between damage to the PFC & familial aggression? 

Grafman

How does amygdala activation correspond with aggression?

Amygdala activation enables us to feel emotions. One way it does this is by stimulating physiological preparedness for f/f/f response. Aggression is an adaptive response and is the "fight" response.  Therefore amygdala activation may lead to increase aggression (or anxiety).  

400

How did Passamonti et al manipulate serotonin levels in the brain?

They had participants drink a placebo or a drink that decreased tryptophan.

400
What part of our brain may play a role in system two processing of information?
the ventromedial prefrontal cortex
400

What does the Iowa Gambling Task gage (measure)? 

risk assessment

400

Which researcher(s) investigated the role of the MAOA gene and the impacts on social behaviour in children, using twins in their research? 

Raine and Baker (2007)

500

10% of which hormone can cross the blood-brain barrier and diminish grey matter in the hippocampus and PFC while activating the amygdala? 

Cortisol


500

Which phenotype of a gene leads to higher levels of serotonin in the brain? 

MAOA-L 

500

What part of the brain are the amygdala and hippocampus located in?

temporal lobe

500
How many trials were there in Bechara et al's study on ventromedial pfc damage and the Iowa Gambling Task?
100

HL extension: Which psychologists studied aplysia in order to see how fear conditioning reshapes the brain connections? 

Kandel
