Measuring brain activity while a person performs a task
Measures blood flow to identify increased neurological activity due to increased demand for oxygen
Strength - Non-invasive
Strength - no harmful radiation
Strength - objective and reliable rather than verbal reports
Weakness - not a direct measurement but just for particular areas, so quite general and not truly qualitative
Weakness - Critics argue it overlooks networked nature of the brain by only looking at specific areas and that it is the communication between areas that provide vital information
