biological approach

Question 1

assumptions of biological approach

Answer 1

everything psychological has a biological basis
we must study biological processes and structures to understand behaviour
the mind lives within the brain

Question 2

what is the biological approach

Answer 2

a perspective that emphasizes the importance of physical processes in the body such as genetic inheritance and neural functions on behaviour

Question 3

4 main topics of biological approach

Answer 3

neurochemical basis of behaviour
genetic basis of behaviour
evolution of behaviour
genotype and phenotype

Question 4

what can low levels of serotonin lead to

Answer 4

OCD

Question 5

what can high levels of dopamine lead to

Answer 5

schizophrenia

Question 6

what does the neurochemical basis of behaviour suggest

Answer 6

chemicals in the brain regulate psychological functions. thought and behavior relies on chemical transmission

Question 7

what has imbalances of neurotransmitters been linked to

Answer 7

mental disorders

Question 8

what do twin studies analyse?

Answer 8

concordance

Question 9

what is concordance ?

Answer 9

similarities in characteristics

Question 10

what are monozygotic twins

Answer 10

share 100% of the same genes - identical

Question 11

what are dizygotic twins ?

Answer 11

share 50% of the same genes - non identical

Question 12

what are genes ?

Answer 12

consist of our DNA and make up for our psychological and physical features

Question 13

what is genotype?

Answer 13

set of genes a person possesses and has inherited

Question 14

what is phenotype?

Answer 14

gene that is expressed

Question 15

what is evolution ?

Answer 15

changes in inherited characteristics in a biological population over generations

Question 16

what do genotype and phenotype illustrate

Answer 16

human behaviors dependency upon interaction between genes (nature) and environment (nurture)

Question 17

evaluate biological approach.

Answer 17

+ scientific methods = highly precise tech and research methods such as FMRIs and twin studies. we can more accuratley asses biological and neural processes in ways that are less prone to bias. reliable date ^ validity
+ PA drug therapy that can treat serious mentall ilnesses such as depression. Useful sufferers can manage their condition
- deterministic
- reductionist

Question 18

what is natural selection?

Answer 18

any behaviour that increases the likelihood of survival will continue in future generations. the posessor more likely to survive passes on traits so more of that specie have their traits.

for example, we need to continue future generations by reproducing so our mating stiles are enhanced in order to optimise reproduction. This is through specific selection named intra and inter sexual selection.
