Dopamine
Serotonin
Noradrenaline
Histamine
What happens when someone has a faulty MAOA gene?
It makes you hungry.
It increases hormone levels.
Leads to less production of MAOA enzyme.
Lower levels of aggression are displayed.
Low production of the Enzyme MAOA can lead to...?
(a)
The MAOA gene has been nicknamed the 'warrior gene'.
True
False
The experiment that supports this genetic theory was conducted by who?
Freud and Little Hans
Sheldon and Body shapes
McDermott and the hot sauce study
Mednick and the adoption study
Those with a low activity MAOA were (a) to issue the punishment in the experiment.
On strength of the McDermott experiment was:
There was a mix of males and females taking part.
It had low ecological validity.
It was conducted in a lab setting so it had high control over variables.
Select the 2 correct evaluation that challenge the MAOA gene theory.
Lack of evidence to support the theory that a single gene can cause aggression.
It has low internal validity as it was a lab experiment which means there was less control over extraneous variables.
The control variables weren't constant throughout the experiment which makes them unreliable.
The MAOA gene theory is too deterministic as it suggests a singular mutated gene can cause criminal behaviour.
