the biological approach Flashcards
(8 cards)
ao1 assumption
everything is innate and governed by biology
ao1 twin studies
often used to ascertain whether or not a behaviour has a genetic basis
when comparing mz&dz concordance rate for mz is higher, it can be determined there’s a genetic basis for behaviour
phenotype
observable characteristics of an individual, which is a consequence of interactions between the genotype and environment
genotype
collection of inherited genetic material thats passed from generation to generation
natural selection, charles darwin
any genetic material that can aid survival of an individual is passed on to their offspring w the effect that any those with the alleles that allowed this behaviour will survive
ao3 strength= real world application
increased understanding of neurochemicals processes in the brain is associated with the use of psychoactive drugs that increase levels of the neurotransmitter seretonin at the brain synapse.
such drugs have been associated with reduction is depression symptoms
this means that people w depression may be better able to manage their condition & live life in community rather than hospital
ao3 strength= scientific methods
uses scientific methods of investigation to investigate the genetic and biological basis of behaviour, the bio approach makes use of a range of precise and highly objective methods (frmi’s/eeg).
with advances in technology, it’s possible to accurately measure physiological and neural processes in ways that aren’t open to bias.
means much of bio approach is based on objective & reliable data
ao3 limitation= biological determinism
determinist in that it sees human behaviour as governed by internal, genetic causes over which we’ve no control.
however we’ve already seen the way in which individuals genotype is expressed
