Electrophysiological signatures of visual lexical processing: open- and closed-class words.
This paper presents evidence of the disputed existence of an electrophysiological marker for the lexical-categorical distinction between open- and closed-class words. Event-related brain potentials were recorded from the scalp while subjects read a story. Separate waveforms were computed for open- and closed-class words. Two aspects of the waveforms could be reliably related to vocabulary class...
متن کاملElectrophysiological signatures of event words: Dissociating syntactic and semantic category effects in lexical processing.
Numerous theories have been proposed regarding the brain's organization and retrieval of lexical information. Neurophysiological dissociations in processing different word classes, particularly nouns and verbs, have been extensively documented, supporting the contribution of grammatical class to lexical organization. However, the contribution of semantic properties to these processing differenc...

متن کاملSemantic processing of open- and closed-class words: an event-related potentials study.
Previous research on open- and closed-class words has revealed the existence of several differences in the processing of these types of vocabulary. In this paper the processing of open- and closed-class words was compared by means of an early electrical brain response, recognition potential (RP), which indexes semantic processing and originates from basal extrastriate areas. The effects of word...
متن کاملA New Model for Lexical Choice for Open-Class Words
The lexical choice process should be regarded as a constraint satisfaction problem: the generation system must choose a lexical unit that is accurate (t~mthful), va//d (conveys the necessary information), and preferred (maxirnal under a preference function). This corts~aint-based architecture allows a clema separation to be made between what the system knows of the object or event, and what the...
