Question 15

AO3 strengths

Answer 15

strength
- its scientific
- uses a range of precise and highly objective methods which include scanning techniques like fMRI and EECs
- Due to technological advances, its possible to accurately measure physiological and neural processes in ways that aren’t open to bias
- strength as it’s based on objective and reliable data
strength
- Real world applications
- increased understating of neurochemical processes in the brain is associated with use of drugs as antidepressants which increase serotonin in synapses
- people can manage their conditions and live in society

Question 16

AO3 weaknesses

Answer 16

weakness
- sees human behaviour as governed by internal genetics which we have no control over
- eg a purely genetic argument can’t explain why people commit crimes when there’s no crime gene
- the way an individual’s genotype is expressed as heavily influenced by environment
- its too simplistic and ignores mediating effects of environment
