psychology - biological approach AO3

• pro - real-world application - increased understanding of ----------- processes that control --------:

  list 3 examples mental health illnesses that psychoacitve drugs can fix

  increased understanding of biochemical processes that control behaviours

  depression, ocd and schizophrenia with high success rates
• how does the drug therapy of SSRI work

  works via increasing serotonin levels in brain as we now know serotonin used for regulating mood
• what did soomro 2008 discover

  effective in alleviating things like ocd -----> people can live in communities than sitting in hospital
• whats the actual assurance that an approach is tested using the scientific method and what does it mean at the end


  studies take place in highly controlled environments so researcher able to replicate research studies under experimental conditions --------> adds validity to original findings
• whats an example of using scientific research method to study this approach

  brain imaging and recording measures
• whats the good thing about having objective results

  create generalised laws about where specific behaviours are located in brain
• what did peterson do in 1998 to further solidify the scientific approach


  used fMRI scans to demonstrate how:

  borcas area was active during speaking test

  wernickes area was active during listening test
• how is it a problem, in twin studies, that biological cant separate the effects of nature and nurture

  since identical twins, non identical twins and related family have genetic similarities, so theoretically any. behavioural similarities must be genetic from a biological perspectives
• how is the fact family members are exposed to similar environmental conditions is a variable a problem from the biological approach

  findings can easily be interpreted as supporting nature(genes/ from birth) than nurture(enviromental stimuli)
• why is the concordance for MZ twins never 100 a bad thing

  since MZ share 100% of genes, expect to share same behavioural characteristics
• what did the study by gottsman and corey find about ocd

  found concordance rate for OCD symptoms for MZ twins to only be 87%, 47% for dz twins -----> suggests how other factors from enviroment impact on behavioural characters -----> suggest behaviours innate AND leant
• problem - bio determinism

  means people could explain ------- and ------- behaviour as a ------ of their -------

  people could explain immoral and deviant behaviour as a result of their biology
• name an example of a gene that creates more aggressive behvaiour

  MAOA - causes reduction serotonin in brain
• how does this cause a conflict with our legal system

  could make people say how that its a person faulty biology of the individuals that led to immoral behaviour
• what unethical programs could be installed to track negative genes

  also removes a sense of ---- ----

  genetic screening ----> genetic engineering a population less likely to do immoral things

  also removes a sense of free will
• what is biological reductionism in short

  tries to explain complex human behaviour by reducing it down to easy explanation
• give an example of a simple explanation to aggressive behaviour(hormone)

  testosterone levels high
• why cant you assume that testosterone is the only cause of aggression

  other possible factors such as sleep deprivation, other cultural/ environmental/ cognitive factors
• this other possibilities to a behaviour means biological takes a what approach
