Strength

• The limitations of EEG are partly addressed through the use of ERPs
• These bring much more specificity to the measurement of neural processes than could ever be achieved using raw EEG data
• as ERPs are derived from EEG measurements, they have excellent temporal resolution, especially when compared to neuroimaging techniques such as fMRI, and this has led to the widespread use in the measurement of cognitive functions and deficits
• researchers have been able to identify many different types of ERP and describe the precise role of these in cognitive functioning; for instance, the P300 component is thought to be involved in the allocation of attentional resources and the maintenance of working memory
