S: ERPs allow researchers to isolate and study how individual cognitive processes take place in the brain while EEGs record general brain activity
L: ERPs have very poor spatial resolution, some processes can’t be studied by ERP as they can’t be presented a large number of times with the same response
S: post mortem: the high spatial resolution of post mortem allows the study of microscopic brain structures down to the neuronal level
L: as post mortem is not conducted on the living brain, unusual behaviour in life and damage found is correlational
