biological

-everything psychological is first biological

-to fully understand human behaviour we have to look at the biological processes and structures

-mind lives in the brain

Genetic basis of behaviour

-traits such as personality are inherited from parents

-twin studies used to investigate whether certain characteristics are genetic, studied using concordance rates (how often a pair share a trait or characteristic)

genotype and phenotype

Genotype- a persons genetic makeup

Phenotype- the way that genes are expressed through physical, behavioural and psychological characteristics

-the biological approach would accept that much of human behaviour depends on a interaction between inehirted factors and the environment
