  • Aggression - Behaviour aimed at harming others
    • Biological explanation
      • (Male) Hormones - Chemicals released by our endocrine system that affect how we behave.
        • Testosterone
          • Violent criminals - higher levels than non-violent criminals
      • Chromosomal abnormalties
        • Violent criminals - high proportion with extra Y chromosomes
        • XYY
      • Brain damage
        • Limbic system - Influences eating, sexual behaviour and aggression.
          • e,g. Charles Whitman
        • Prefrontal cortex - The front of the brain that is involved in social and moral behaviour and controls aggression.
    • Psychodynamic explanation
      • Freud
        • Thanatos - Part of our unconcious that causes aggressive drive.
          • Drives us towards self destruction.
          • Builds up inside us and creates pressure until we can't control it and it makes us act aggressively.
            • John Dollard disagreed that it would 'spill over' into aggression for no reason.
              • Frustration-aggression explanation
                • We need something to frustrate us before becoming aggressive.
        • Ego defence mechanisms - Behaviour strategies used to protect ourselves.
          • Displacement - Being aggressive to other people.
          • Sublimation - Challenging aggression into acceptable activities.
    • Social learning theory
      • Observation and imitation
        • Vicarious learning - Learning by observation.
        • Clearly demonstrated by children.
          • Implication - punishment can have the opposite effect of what is intended.
            • (Role model) Parent hits child - child learns to hit others.
        • Similar role models
      • Monitoring - Judging whether our own behaviour is appropriate or not.
        • Bandura
          • If we feel good about what we've done it will strengthen behaviour.
    • Development of Agression
      • Biological
        • Young et al - Effect of hormones.
          • Injected pregnant monkey's with testosterone.
            • Females grew up to behave like males therefore testosterone plays a vital part in aggression.
        • Raine - Brains of murderers
          • 41 murderers in California given a PET scan to compare with non-murderers
            • Lower activity in the prefrontal cortex of murderers therefore this factor can lead people into commiting violent crimes.
      • Frustration-aggression
        • Barker - Effect of frustration
          • Children kept waiting before allowed to play with toys and behaviour observed.
            • Children more aggressive than others not frustrated therefore frustration does lead to an increase of aggression.
        • Megargee and Mendelsohn - Link between aggression and personality type
          • Brutually aggressive criminals were interviewed and given personality tests.
            • Criminals repressed anger until built up and exploded therefore if we contain aggressive instinct for a long time, it will build up and become uncontrollable.
      • Social learning
        • Bandura et al -  3-6 yr old children and imitation
          • 96 children divided into 4 groups. Three shown aggressive behaviour towards bobo doll. Behaviour observed
            • Children shown aggressive behaviour were more aggressive to the dolls therefore children will copy others.
        • Liebert and Baron - Effect of violent TV on aggression in children
          • One group shown violence, other shown sports. Observed at play.
            • Violence group more aggressive therefore watching violent programmes increase aggression in children
              • Charlton - Introduced TV to see if it would affect aggression in children.
                • Behaviour recorded over 2 years but showed no increase. Therefore watching role models doesn't make children copy aggressive behaviour.
                • High ecological validity
                • Longitudinal
                • Contradicts
          • Contradicts
    • Reducing aggression
      • Biological
        • Drugs
          • Ritalin
            • Attention Deficit Hyperactivity Disorder (ADHD)
            • Stimulates brain activity
        • Psychosurgery - An operation on the brain to remove the abnormality.
      • Psychodynamic
        • Ego defence mechanisms
        • Catharsis - Watching others experience emotion to get rid of your own
      • Social learning
        • Bandura - Effect model being punished for aggression on imitation.
          • Children shown model being either punished or reinforced.
            • Punished group less aggressive therefore punishment reduces aggression.
        • Huesmann - Effect of teaching children to think more carefully about what they see and aggression.
          • Told what happens on TV is not real. Behaviour compared to group without training.
            • Trained children showed less aggression therefore it can be reduced by making TV models less influential
          • Parents do not have training to explain concepts in a way children can understand.
          • Parents not always present to discuss programmes afterwards.
  • Thanatos - Part of our unconcious that causes aggressive drive.
    • Drives us towards self destruction.
    • Builds up inside us and creates pressure until we can't control it and it makes us act aggressively.
      • John Dollard disagreed that it would 'spill over' into aggression for no reason.
        • Frustration-aggression explanation
          • We need something to frustrate us before becoming aggressive.
  • Laboratory -  Lack of ecological validity

A very colourful and well detailed mind map for aggression - this would be great for any visual learners out there!
