- 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
- Central Nervous System
- 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
- Twin and Adoption Studies
- 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
- Are transgender operations in children ethical?
- Practical
- 'Do males have better spatial ability than females?'
