biological approach

Question 1

biological approach

Answer 1

importance of physical processes in the body like genetic inheritance and neural function

Question 2

genes

Answer 2

make up chromosomes and consist of DNA which codes to physical features of an organism and psychological features
-transmitted from parents to offspring

Question 3

biological structure

Answer 3

an arrangement or organisation of parts to form an organ,system of living thing

Question 4

neurochemistry

Answer 4

relating to chemicals in the brain that regulates psychological functioning

Question 5

genotype

Answer 5

The particular set of genes that a person possesses

Question 6

phenotype

Answer 6

The characteristics of an individual determined by both genes and the environment

Question 7

evolution

Answer 7

The changes in inherited characteristics in a biological population over successive generations

Question 8

assumptions of behaviourist approach

Answer 8

Suggest that everything psychological is at first biological, so to fully understand human behaviour. We must look at biological structures and processes within the body.

Question 9

genetic basis of behaviour

Answer 9

Behaviour geneticists study whether behavioural characteristics such as intelligence, personality, mental disorder etc. are inherited in the same way as physical characteristics such as height and eye colour.

Twin Studies are used to determine the likelihood that certain traits have a genetic basis by comparing concordance rates between pairs of twins

Monozygotic (MZ) twins = higher concordance rates than dizygotic (DZ): suggests a genetic basis

MZ= share 100 % of genes
DZ= 50%

Question 10

Evolution and behavior biological approach

Answer 10

Natural selection main principle is that genetically determined behaviour that enhances an individual survival will continue in future generations, so it will remain in gene pool unless individual does not reproduce

Question 11

strength of the biological approach

Answer 11

P - scientific
E - measurable and observable so can e tested in controlled conditions
E - brain scanning techniques - highly controlled
L - highly controlled supported by empirical evidence

Question 12

limitation of the biological approach

Answer 12

P - family twin studies struggle to disentangle influence of nature and nurture
E - due to genes - similarities
E - all exposed to same environment
L - findings easily interpreted supports
