Biological Approach^ Flashcards
Assumptions
everything psychological is first bio
genes affect beh
influences psy differences
mind lives in the brain
- contrast to cog app. who sees them seperate
Neurochemical Basis of Behaviour
actions of chemicals in the brain
- neurotransmitters
response to beh/ thoughts process
imbalance in the neurotransmitters links to mental disorders
Genotype
genes determine characteristics
Phenotype

Real World Application
understand of neurochemical process in the brain increases
drug therapy - antidepressants
increases the understanding of neurochemical processes
Scientific Methods
objective / precise
brain scanning measures it in an unbias way
reliable and objective data
Biological Determinism
only sees human beh as govern by internal bio factors (genes)
phenotype is influenced by envi
Twin Studies
monozygotic - 1 zygote, 100% identical concordance rate
dyzogotic - 2 zygote, non identical, lower rate
Family Studies
Galton’s
- all natural abilities are inherited
- observe families characteristics
Adoption Studies
nurture
compare non bio family traits
Selective Breeding
breed for desired characteristics to be passed down
