biological approach

Question 1

uses scientific methods

Answer 1

in order to investigate genetic and biological basis of behaviour, the biological approach makes use of a range of precise and scientific methods such as scanning techniques and drug trails
it is possible to measure biological and neural processes in ways that are not open to bias.
biological approach is based on reliable data

Question 2

deterministic

Answer 2

biological approach is determined because we see human behaviour governed by internal biological causes over which we have no control
however this is at odds with the legal system as offenders are seen as responsible for their own actions
the discovery of the criminal gene may complicate this theory
negative implications for wider society as criminals find an excuse for their behaviour

Question 3

difficulty of separating nature and nurture

Answer 3

identical twins, non identical twins, member of the same family who have the same genes are likely to behave in a the same way
however, the fact that family member are exposed to similar environmental conditions an important confounding variable
limitation because findings could be interpreted as supporting nurture rather than nature
