- Biological Approach 1
- Strengths
- Scientific
- Uses experimental methods
- Gives good objective evidence
- Uses experimental methods
- Strong argument for nature side of nature/nurture debate
- Lots of practical applications
- Can give treatment knowing the biology of disorders
- Scientific
- Limitations
- Reductionist
- Reduces all human behaviour to physical processes
- Over simplistic
- Can't explain consciousness and self awareness
- Ignores influence of environment
- Deterministic
- Ignores individuals' thoughts and feelings
- Behaviour is due to your biological makeup
- Ignores individuals' thoughts and feelings
- Reductionist
- Evolution of behaviour
- Change of characteristics and makeup of a population over successive generations
- our nervous system is the product of evolution
- It is likely evolution has influenced out behaviour
- All animals are related meaning all brains and CNSs are related
- Brain and behaviour have been gradually built up through evolution, from simple to complex
- Ways to investigate
- Family study
- Twin study
- Adoption study
- Genotype
- a person's genetic makeup
- Phenotype
- The expression of the genetic makeup - their physical appearance
- Influence of genes
- Genetic information is passed on to the next generation through genes
- development of the brain is passed on through genetic information
- this can change how people behave
- development of the brain is passed on through genetic information
- Genetic information is passed on to the next generation through genes
- Explaining human behaviour
- Different areas of the brain are responsible for different types of thinking and behaviour
- Genetic influences particular types of behaviour
- E.G. schizophrenia (a psychological disorder) causes hallucinations and is said to be a malfunction of the nervous system because of a faulty gene
- Chemical processes - hormones and neurotransmitters
- Over-activity and under activity of these can result in changes in feelings and behaviour
- Strengths
- Reduces all human behaviour to physical processes
