EEG

Question 1

strength: high temporal resolution

Answer 1

allows researcher to take a real time recording of brain activity rather than still image (as is case w FMRI and PM) researcher can gain more accurate measure of general brain activity in a particular task, provides greater insight into processes of the brain such as activity of brain during sleep, increasing validity

Question 2

weakness: low in spatial resolution

Answer 2

only provide information on general activity in the brain, cannot pinpoint exact source of neural activity involved in behaviour, unlike ERP which allow researcher to identify specific brain activity in particular task, findings may be less valuable in developing understanding than by using alternative ways of scanning brain eg ERP
