- Biological Approach
- Assumptions
- The brain structure and functions can help us explain our thoughts
- Genes, neurochemistry and the nervous system help us apprehend
- Genetic Basis
- If behavioural traits are inherited like physical ones
- Twin Studies
- Identical twins are found to have higher correlation rates for behavioural traits
- Identical twins share 100% DNA
- Genotype and Phenotype
- Phenotype- the way genes are expressed
- Genotype- genetic makeup
- The environment affects the genotype expression
- E.G. identical twins can look different is one exercises more
- Human behaviour is affected by the interaction between the environment and genetics
- Evolution and Behaviour
- Natural selection
- Those with more advantageous genetics will survive and pass down the genes to keep the traits in the gene pool
- Evaluation
- Scientific- uses a range of precise methods, such as fMRIs, so we can measure biological processes
- Real-Life- has led to the development of psychoactive drugs to treat mental illnesses which allow patients to live more normal lives
- Determinist- implies we have no control over our actions
- Cannot Separate Nature and Nurture- identical twins likely come from similar environments so the results could be supporting nurture more
- Assumptions
