Decision making, problem solving and planning. Responsible for personality expression.
2 of 13
Damage to the pre-frontal cortex?
Can lead to impulsivity, loss of self control, immaturity, altered emotionality and inability to modify behaviour.
3 of 13
Role of hypothalamus?
Plays an important role in producing hormones that help control different cells and organs and that govern physiological functions.
4 of 13
Damage to hypothalamus?
Can cause outbursts of aggression and violence.
5 of 13

AO3 - Research support?
Phinease Gage (case study) had a metal rod go through his head and became much more aggressive after the accident, demonstrating that damage to the brain can cause major changes to a person and their aggression levels.
8 of 13
AO3 - Compliments to research support?
Use of case studies can be highly valid - brain structures can be isolated and measured in a variety of ways. Such measurements are highly reliable and scientifically credible, therefore removing bias and increasing objectivity.
9 of 13
AO3 - Criticisms of research support?
Case studies tend to assume that brain injury caused the aggression, but there are other possible factors. Therefore we cannot establish a cause and effect relationship.
10 of 13
AO3 - Differing theories?
Social learning theory - Criminality is a result of having criminal/aggressive role models.
11 of 13
AO3 - Any other points?
Brain injury focuses on bio factors and ignores other factors - as such, it is limited on its own.
12 of 13
AO3 - Any other points?
Theory suggests that criminal behaviour is the result of brain damage and that an individual has no free will in their behaviour. Deterministic.
