Evaluation: biological approach
Strength: uses scientific methods of study
To investigate the genetic and biological basis of behaviour, the biological approach makes use of precise and highly scientific methods, including scanning techniques such as fMRIs and EEGS, family and twin studies and drug trials. With advances in technology it is possible to accurately measure biological and neural processes in ways which are not open to bias. This means that the biological approach is based on reliable data.
