  • Key Concepts
    • Criminal Behaviour
      • Core Theory
        • Nature ( biological) vs nurture ( social learning theory) debate
        • Heritability= the proportion of behaviour that is due to genetic factors
        • Biological Theory
          • criminal personality and criminal behaviour is inherited, their DNA has programmed them to become a criminal. Criminal behaviour is passed down through families in genes. If your parent is a criminal you have a higher chance of becoming a criminal.
          • As criminal behaviour is abnormal the biological theory argues that the brains of criminals are “abnormal” this is brain dysfunction.
        • Brain Dysfunction
          • Pre frontal cortex= the area is under active in some criminals which means criminals can’t from an association between fear and anti-social behaviour leading to not fearing the consequences of their behaviour
          • Limbic system= criminals have increased activity in this area, this creates higher levels of aggression.  Research shows the amygdala dos not function normally in psychopaths can lead to crimes such as ****
          • Corpus callosum= less active in criminals therefore less communication between rational and irrational sides of the brain, leads to irrational crimes such as theft or mugging
          • Temporal Lobe= in criminals activity is slower in aggressive psychopaths, leads to slower learning from their actions
    • Crime= a criminal act which breaks the law, intends to break the law
    • Problems with measuring crime-
      • 1. Statistics count the number of criminal acts rather than the number of criminals
      • 2.People may not be aware that they are victims of crime
      • 3. Victims do not always want to report crime for a number of reasons
    • Criminal personality= a collection of traits that make a person different from a  “normal” law abiding person
      • Impulsivness
      • Lack of feeling of guilt
      • Pleasure seeking
      • Over Optimistic
      • Self importance
