Idea
Perspective emphasising importance of physical processes in the body such as genetic inheritance and neural function.
Parts to it
Assumptions
Genetic basis of behaviour
Genotype and phenotype
Evolution and behaviour
Assumptions
Biological processes: genes, neurochemistry and nervous system
Genetic basis of behaviour
Twin and family studies used to determine likelihood that certain traits have a genetic basis by comparing concordance rates to see to the extent they share similar characteristics.
Genotype and phenotype
Genotype: Actual genetic makeup
Phenotype: Way genes are expressed through physical, behavioural and psychological characteristics (environmental factors).
Evolution and behaviour
Darwins natural selection. Genetics behaviour enhances chance of survival and reproduction in future generations.
