Biological Assumptions |
Genes influence behaviour: genotype (genetic) and phenotype (environmental). Biological structures e.g. the nervous system and the brain are the most important in producing feelings and behaviour. NATURE. Brain chemistry influences behaviour and chemical imbalances can cause mental disorders e.g. schizophrenia. Case study: testosterone prisoners According Darwin's theory of evolution, humans have evolved from animals so have much in common with the ones close on the evolutionary tree. There is behavioural continuity between species and so can generalise animal findings to humans, as we have the same basic instincts. |

Research methods |
PET Scans (Scientific): +scanning increased understanding of brain. +less invasive and gives more accurate measurements of brain activity to investigate localisation of function. -involves injection of radioactive glucose into bloodstream. Case studies: HM surgery to treat epilepsy, severe amnesia, proof brain is involved in memory. -not generalisable -unique case -small sample +in depth detail Experiments: prisoners and testosterone levels and crimes commited more violent=higher testosterone levels. -which causes which? +evidence for hormones influencing behaviour +objective |
