Flashcards in Aggression neural and hormonal mechanisms Deck (24):
1

What did Brown find in 1982?

There was less serotonin metabolic waste products in the cerebrospinal fluid in more aggressive individuals.

2

What did Mann find in 1990? What direction does it support?

Men scored higher on aggression after the reduction of serotonin by drugs. Serotonin causing aggression.

3

What did Ferrari find in 2003? What directions does it support?

Rats who had fought for ten days at the same time had higher levels of dopamine and lower levels of serotonin on the 11th day. Suggests aggression causes the changes in neurotransmitter levels.

4

What did LeVine find in 1997?

An increase in dopamine is linked to an increase in aggression.

5

What did Buitelaar find in 2003? What direction does this support?

A reduction in dopamine using an anti-psychotic drug led to a reduction in aggression. Dopamine causes aggression.

6

What did Couppis find in 2008?

Dopamine is linked to movement and self-initiated actions, so the increase in dopamine could be due to an increase in movement in Ferrari's study.

7

What did Nelson find in 1995?

Found a positive correlation between testosterone and aggression levels.

8

What did Wagner find in 1979? What model does this support?

Aggression decreased when mice were castrated and increased when testosterone was injected. The Basal model.

9

What did Mazur and Booth find in 1998? What model does this support? What makes it special?

Testosterone level of air force veterans increased following divorce. It supports the reciprocal model. A longitudinal study using 4 medical examinations across 10 years.

Stimulating the lateral hypothalamus in rats led to increased preditorial aggression.

20

What was the case of Phineas Gage?

After a tamping iron when through his head he became aggressive and rude.

21

What did Raine find?

Using brain scans on people with anti-social personality disorders he found that had 11% less neurons in the pre-frontal cortex than normal people.
