biological approach Flashcards
scientific methods
FMRI+EEG used for genetic and biological basis of behaviour. advances in techno; measure physiological and neural processes without bias. therefore it is based on objective +reliable data
biological determinism
sees human behaviour determined by internal and genetic causes. however in reality, genotype is influenced by phenotype. a purely genetic explanation becomes problematic when we consider criminality (crime gene?) therefore it is too simple and ignores environmental factors
real world application
increased understanding of neurochemical processes is associated with psychoactive drugs; anti-depressants that increase serotonin levels. this decreases hospital admissions as people can manage their symptoms at home.
cannot separate nature and nurture
assumes that similarities are due to similar genes. similar environments are confounding variables here. explains why DZ twins have higher conc rates than normal siblings even though 50% are same genes= share more environmental exp
natural selection
critics of darwin; karl popper claim that it is not possible to prove/falsify the evolutionary theory as we cannot see it and can only infer. however, others claim that basic principles are supported by fossils
