The study introduces the Event-Related Potential method in neurolinguistics, an electrophysiological method based on Electroencephalogram (EEG) data, used to assess on-line processing of cognitive activity focusing on the measurement of Event-Related Potentials (ERP). ERPs can be utilized when a comprehender’s only task is to understand a word, phrase or sentence or to produce names or more elaborate utterances. Recording electrical brain activity in response to written and spoken words (as well as smaller and larger linguistic units) thus provides a means of tracking the brain’s sensitivity to various linguistic inputs, revealing which factors are important to processing and the time course of their infl uence. Diff erent types of neural activity are introduced: N100, P200, N200, P300, N400, P600. Then, foundings from various studies are presented; that semantic processing of a word begins even before it is uniquely identifi ed and that there is a continuous mapping from linguistic input onto semantic representations, specifying words’ semantic, phonological and syntactic properties.
