Brain Exp of aggressiom

• Frontal lobe

  
  

  decision making, personality, mental processes such as forward planning and speech​
• Temporal lobe

  processing sensory input (primarily auditory)​
• Parietal lobe

  processing sensory information - primarily visual
• Occipital lobe

  visual processing​
• Prefrontal cortex

  Function - Logical thinking, forward planning, decision making and regulating emotions​

  Left hemisphere – positive emotions​

  Right hemisphere – negative emotions

  Damage - Issues with anger management, impulsive actions due to not thinking about consequences, and lack of forward planning
• Right Amygdala

  Function - Maintaining emotions, emotional behaviour and motivation​

  Damage - Increase of brain activity so flood of emotions, emotional instability​
• Left Amygdala​

  Function - Response to internal and external stimuli to provide instinctive feelings and behaviours – fight or flight instinct​

  Damage - Instability in the response – choose to fight more often​
• Hypothalamus

  Function - Regulating and releasing hormones including those that regulate sexual function. Testosterone - aggression​

  Damage - Hormonal imbalance, so an increase in the levels of some hormones e.g. ​
• :) Supported by phineas gage

  Large metal rod went through his frontal lobe in a railway accident, and as a result his personality changed. T/f showing frontal lobe is connected to personality​
• :) Practical applications

  shows that damage to a part of the brain can cause specific symptoms, scientists can predict symptoms and place measures to reduce. T/f improving qual of life​
• :( Behavioural Determinism

  shows behaviour as predetermines, individuals lack free will. T/f have no responsibility over behaviour as they were 'born that way'​
• :( Reductionist

  Neural circuits, nature, other theories like SLT/ T/g insufficient explanation of behaviour
• Brain (aggression)

  :) Supporting evidence - Phineas Gage

  :) Practical Applications

  :( Behavioural Determinism

  :( Reductionist - nature
• Brain Structure

  A) Frontal Lobe

  B) Parietal

  C) Occipital

  D) Temporal
