  • Biological Approach
    • Weaknesses
      • Bad temporal resolution
      • No functional detail
      • Loud banging noise
      • No metal  - practical issue
      • Relating to behaviour - normally relate brain activity to behaviour
    • Research Methods
      • EEG Scans
        • Records electrical activity
          • Strengths
            • Safe and painless
            • Good temptoral resolutions
            • Ease of relating behaviour to acticity
          • Weaknesses
            • Not good structural detail
      • Post Mortem Investigations
        • Looking at brain after death
          • Strengths
            • Good structural detail
              • Large scale - by eye
              • Small scale - lookig at tissues through microscope
          • Weaknesses
            • No temproal resolutions (brain is not functions)
            • No functional detail (brain non-functioning)
            • Can't link to behaviour directly (person is deceased)
              • Can ask family members
            • Need order from coroner's and consent from family
      • PET Scans
        • Detects radioactive decay in parts of the brain
          • Strengths
            • Not much distress to patient
            • Good temporal resolution
              • Has timescale
            • Good functional detail
          • Weaknesses
            • Patients have to stay still - uncomfortable
            • Long procedure
            • No structural detail
      • MRI scans
        • Detects radio frequency signals
          • Strengths
            • Good structural detail
          • Weaknesses
            • Bad temporal resolution
            • No functional detail
            • Loud banging noise
            • No metal  - practical issue
            • Relating to behaviour - normally relate brain activity to behaviour
    • Assumptions
      • Human behavious is strongly influenced by our genetic makeup and our genetic inheritance
      • CNS is essantial for thought and behaviour
        • Structure of brain can explain thought and behaviour
      • Chemical processes are responsible for psychological function in the brain
        • imbalance of chemicals can cause psychological disorders
      • Humans have evolved biologically
        • Darwin's Theory
          • We have a lot in common with other animal;s
  • Good functional detail
    • Strengths
      • Safe and painless
      • Good temptoral resolutions
      • Ease of relating behaviour to acticity
