Biological Theory and Crime

Flashcards about the Biological Theory of criminology, covering brain dysfunction, the pre-frontal cortex, and the amygdala.

Biological Theory

The theory that criminals are pre-programmed through their DNA (genes).

Biological theory 1

Claims that criminals are pre-programmed through their DNA (genes).

Pre-frontal cortex

Area of the brain responsible for higher level mental functions such as reasoning, planning ahead, problem-solving, and rational decision-making.

Underdeveloped pre-frontal cortex

In criminals, it is often found to be underactive and underdeveloped, leading to impulsive and irrational decisions.

Amygdala

The emotional and motivational center of the brain; activated when something scary happens.

Amygdala in criminals

In criminals, these areas have been found to show increased activity within brain scans.

Amygdala in violent criminals

Increased activity in these areas can result in a decrease in reasoned thinking and an increase in impulsiveness and aggression.

Brain injury and crime

Brain injury could be caused through illness or injury.
