Abstract

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 bymeans of an early electrical brain response, recognition potential (RP), which indexes semantic processing and originates from basal extrastriate areas. The effects of word frequency on closed-class words were also investigated. For these purposes, open- and dosed-class words, among other stimuli, were presented by means of the rapid stream stimulation procedure. Results showed that there were no significant differences when comparing the RP evoked by open- and closed-class words in the left hemisphere. However. in theright hemisphere this situation changed: the RP evoked by open- and closed-class words did differ. Moreover, there were no differences between the RPevoked by closed-class words and pseudowords, These patterns of results suggest that the semantic processing of closed-class words shares some aspects with the processing of open-class words. despite the existence of some differences. Thus, whereas the semantic processing of open-class words recruits brain areas of both hemispheres, the semantic processing of closed-classwords is left-lateralized. A second purpose of this work is to study word-frequency effects on closed-class words. Our results show the insensitivityof closed-class words to word-frequency effects.
