  • Biological Psychology - our 'Nature' affects our Behaviour
    • Key Terms
      • Central Nervous System
        • The brain and spinal cord, controls most behaviour through passing electrical impulses
      • Neurones
        • Nerve cells which send impulses around the brain and body
      • Synapse
        • A junction between neurones
      • Neurotransmitters
        • Chemicals released by neurones to pass the impulses across the synaptic gap
      • Receptor
        • Protein molecules situated on neurones, they receive the impulses
      • Hormone
        • Chemical released from a gland and affects target organs (such as sex organs)
      • Brain Lateralisation
        • The uneven distribution of tasks carried out by the hemispheres of the brain
      • Genes
        • Inherited units of information
    • Methodology
      • Twin and Adoption Studies
        • Twin - change genes, keep environment same. Adoption - change environment, keep genes steady
      • PET/MRI Scans
        • MRI - structural PET - functional
      • Animal Experiments
        • Animal are used when the IV is invasive, and unethical to apply to humans
    • Gender Development
      • Gender is a result of our genetic make up (e.g chromosomes, hormones, anatomy)
    • Studies
      • Dr Money (1975) - aim: investigate the case of 'Brenda Reimer' as support for his theory of gender neutrality
      • Raine (1997) - aim: discover if murderers who have pleaded not guilty for reasons of abnormality show brain abnormalities in PET Scans
    • Key Issue
      • Are transgender operations in children ethical?
        • Freedom of choice
        • Surgery should not be taken lightly
        • If born with androgen insensitivity syndrome, parents have to decide the anatomical sex of their baby
    • Practical
      • 'Do males have better spatial ability than females?'
