biological approach

Question 1

assumptions of the biological approach

Answer 1

that everything that is psychological is at first biological
mental processes of the mind as being separate from the physical brain

Question 2

what are twin studies used for

Answer 2

to determine the likelihood that certain traits have a genetic basis by comparing concordance rates between twins

Question 3

mz

Answer 3

monozygotic = share 100% of twins genes

Question 4

dz

Answer 4

dizygotic = share about 50% of twins genes

Question 5

genotype v phenotype

Answer 5

genotype their actual genetic makeup

phenotype the way the genes are expressed through physical behavourial and pyschological characteristics

Question 6

natural selection by Charles Darwin

Answer 6

any genetically determined behaviour that enhances an individual’s survival and reproduction will continue in future generations

Question 7

twin case study
investigated the genetic basis for a disorder , twins and grown up in similar environments . concordance rates express the likelihood that a trait is present in one twin it is found in the other

Answer 7

mz = 49%
dz = 17%
ordinary siblings = 9%

Question 8

determinist view of behaviour
weakness

Answer 8

it sees human behaviour as governed by internal biological causes which we have no control over , implications for law and wider society such as the criminal gene

Question 9

nature v nurture
weakness

Answer 9

mz and dz twins have eugenic similarity confounding variable of enviroment

Question 10

scientific approach
strength

Answer 10

due to the biological basis of the approach it uses precise methods such as fmri eegs family and twin studies .based on reliable data

Question 11

real life application
strength

Answer 11

increased understanding of the biochemical processes in the brain has led to the development of psychoactive drugs to treat mental illnesses such as depression , suffers can manage condition then remain in hospitals
