- Biological Approach
- Assumptions
- Everything is first biological than psychological
- To understand human behavior we need to look at biological structures and processes within the body.
- Genetic basis
- Behavior geneticists study whether behavioral characteristics are inherited the same way as physical characteristics
- Twin studies are used to determine the likelihood that certain traits have a genetic basis by comparing concordance rates
- If MZ twins have a higher concordance rate than DZ twins then it would suggest a genetic basis
- Genotype and phenotype
- Genotype (persons genetic makeup)
- Influenced by environmental factors
- Phenotype (way genes are expressed through characteristics )
- Genotype (persons genetic makeup)
- Evolution and behavior
- Darwins theory of natural selection
- Genetically determined behavior that enhances an individuals chances of survival will continue for future generations
- This occurs naturally as some traits give the possessor certain advantages
- This advantages means they are more likely to survive, reproduce and pass on these traits
- Darwins theory of natural selection
- Evaluation
- Real-life application
- Increased understanding of biochemical processes led to the development of psychoactive drugs which helps to treat serious mental illnesses
- Means that patients can manage their conditions and try and have a relatively normal life
- Increased understanding of biochemical processes led to the development of psychoactive drugs which helps to treat serious mental illnesses
- Scientific methods of investigation
- Use of precise and highly scientific methods such as EEGS
- Possible to actcurately measure biological processes in ways that are not open to bias
- Reliable data
- Possible to actcurately measure biological processes in ways that are not open to bias
- Use of precise and highly scientific methods such as EEGS
- Causal conclusions
- Bio approach offers explanations for mental illnesses using neurotransmitters
- This evidence comes from studies that a particular drug reduces symptoms of a mental disorder and it is assumed that the neurochemical in the drug causes the disorder
- Limitation as it is claiming to discover causes when only an association exists
